Protocols: Simple, essential tools to transform your health - the #1 Sunday Times bestseller from the creator of Huberman Lab

by Andrew D. Huberman

THE INSTANT #1 SUNDAY TIMES BESTSELLER

Simple, essential tools to transform your brain function, mood, focus and bodily health – the must-read first book from Stanford neuroscientist and creator of Huberman Lab, Dr Andrew Huberman.

In Protocols, Dr Andrew Huberman introduces simple, science-based practices that can substantially improve your day-to-day mental and physical state. They work the first time, and every time.

Huberman's protocols can help you unlock your brain and body’s full potential across seven sleep; exercise; stress control; nutrition; light; focus, motivation and learning; and personal growth. For example, a simple sleep protocol includes viewing sunlight as soon as possible after waking; a stress protocol involves doing a single breath pattern, once.

In his clear and engaging style, Dr Huberman explains the science behind each protocol, then shows how they can deliver immediate, effective results. What’s more, he described how to customise them, allowing you to adapt them to your individual needs.

Drawing on decades of research – from Dr Huberman’s own work and those of the many experts he has interviewed over the years – he delivers a comprehensive and indispensable guide to help you improve your mental health, physical health, and performance.

This book will transform your life.

About the author

Andrew Huberman, Ph.D., is a neuroscientist and tenured professor in the Departments of Neurobiology and Ophthalmology at Stanford University School of Medicine. His research laboratory, the Huberman Lab, has made significant contributions to our understanding of brain development, the neuroscience of visual perception and repair from blinding diseases such as glaucoma, the neural mechanisms of stress and resilience and neural plasticity—the nervous system’s ability to change and learn in response to experience.

Dr. Huberman earned his bachelor’s degree with honors and distinction from the University of California, Santa Barbara (1998), completed a master’s degree at UC Berkeley (2000) and earned his Ph.D. in neuroscience from UC Davis in 2004, where he received the Allan G. Marr Prize for the Best Ph.D. Dissertation. He conducted postdoctoral research at Stanford University School of Medicine from 2005 to 2010 and was awarded a Helen Hay Whitney Postdoctoral Fellowship.

His first faculty position was from 2011 to 2015 at the University of California, San Diego, in the Department of Neurosciences and the Neurobiology Section in the Division of Biological Sciences. In 2016, he was hired by the Stanford University School of Medicine as a tenured professor, where he currently directs the Huberman Laboratory. Dr. Huberman’s lab has published numerous peer-reviewed research and review articles in the highest-tier journals including Nature, Cell, Science and Neuron.

Across his career, Dr. Huberman has published over 75 peer-reviewed articles in top scientific journals including Nature, Science, Cell, Neuron, Current Biology, and Journal of Neuroscience. He has delivered more than 100 invited research and keynote seminars around the world, and he was a regular member of NIH grant review panels and contributor to the National Eye Institutes Audacious Goals Initiative to cure blindness. His research as a PhD student, postdoc and tenured professor made important discoveries into how the brain processes visual information, how brain circuits develop and function and are modified by experience. He has also published a human randomized controlled trial on the efficacy of stress mitigation tools and ways to improve sleep, heart rate variability and mood.

His research includes key areas such as visual circuit development; the molecular mechanisms that guide precise wiring between the eye and brain; how the brain processes the direction of visual motion; visual and brain circuits for circadian rhythm generation and timing; stress and threat detection circuits in the brain and discovery of neural pathways that trigger defensive behaviors; neural regeneration and methods to promote repair of damaged neural connections; and stress and performance, focusing on how visual inputs and breathing patterns influence brain states.

His research accomplishments have earned him numerous prestigious honors and awards, including the Cogan Award in 2017 for making crucial contributions to vision science and ophthalmology, the McKnight Neuroscience Scholar Award in 2013, and the Pew Biomedical Scholar Award in 2013 for his work on visual circuit function and plasticity. He was awarded the ARCS Foundation Graduate Fellowship for the best PhD dissertation and the Helen Hay Whitney Postdoctoral Fellowship.

Dr. Huberman served on the editorial boards of Current Biology, The Journal of Comparative Neurology, Journal of Neuroscience and Cell Reports and he has reviewed papers for Nature, Science, PNAS, Cell, Neuron and many other top tier journals. He also served on multiple grant review panels for the National Institutes of Health.

He co-directed the Cold Spring Harbor Laboratory course on "Vision: a platform for linking cell types, circuits and perception," training the next generation of vision researchers.

In his teaching roles, Dr. Huberman has taught undergraduate and graduate-level courses in neuroscience, neuroanatomy, and development

[Athan Smyrlis · Rating 4 out of 5]

Fascinating science. More toolbox than operating manual.

The science in this book is fascinating, and Huberman makes complex physiology approachable. Bringing sleep, exercise, nutrition, light and stress into one practical reference, and explaining why each recommendation might work rather than just what to do, is a real service. That earns the four stars.

My reservation is the promise in the subtitle. An operating manual implies that if you follow the steps, the machine runs. Knowing the steps, and even understanding the mechanism behind them, is not the same as knowing whether an approach is right for you.

To be fair, Huberman does not ask anyone to follow every recommendation. The book ranks them by importance and says they should be adapted. But there is a difference between giving readers permission to adapt and teaching them how. The same specificity that makes the protocols appealing can turn health into an ever-expanding list of things to get right. A reader comes away with more options, and more uncertainty about whether they are doing enough.

I read this as a cardiologist who has spent two decades sitting across from people whose lives have been disrupted by shift work, caregiving, pain, medication and grief. The question in that room is rarely just what would improve this person's physiology. It is what they can realistically change, what matters most, and what burden the advice itself will add. This book's knowledge came from a laboratory. It has to be applied in rooms like that one, and it does not always survive the trip.

That is the standard: help me tell the essentials from the refinements, what to try first, how to judge whether it is helping, and when doing less is the better decision. Explaining why an intervention might work does not answer those questions.

Sleep is where this matters most. Advice can turn rest into another performance task. Someone who follows every recommendation and still lies awake needs a way to read that outcome without concluding they have failed. "This is not the answer for me" should feel as available a conclusion as "I was not consistent enough."

This is an excellent education. It is not individualized guidance, and the title promises the second. Read it for the science. Treat the protocols as possibilities to consider, not standards to grade yourself against. And do not mistake difficulty getting better for a failure to try hard enough.

Thank you Simon and Schuster Canada and NetGalley for this ARC.

One of the things I appreciated most about Protocols is that it doesn’t necessarily need to be read cover to cover. You can easily skip ahead to the topics that interest you most or return to certain chapters when they become relevant to you. That said, I loved that the author explains early on that each chapter is intended to be a building block, with the recommendations presented in order of importance. This gives the book a clear structure while still allowing readers to approach it in whichever way works best for them.

I also really enjoyed the personal elements woven throughout the book. In each chapter, the author shares what led him to research that particular area, making the information feel more engaging and accessible. The scientific evidence behind each recommendation is thoroughly explained, including why it may be helpful rather than simply telling readers what they “should” be doing.

Of course, not every recommendation will work for every person, and it is important to consider your own body, circumstances, and individual needs. However, as far as health and self-improvement books go, I found this one informative, practical, and easy to navigate.

If you enjoyed the structured, actionable approach of Atomic Habits, I think this may appeal to you as well. The books cover different subjects, but they share a similar focus on making meaningful improvements through realistic, intentional changes.

Andrew Huberman is an absolute machine of a man. It takes a special kind of person to manage running a successful podcast, being a tenured professor at Stanford, being a social media celebrity on top of a rotation of sexual partners at his old age. They even tried to cancel him for having too much motion few years back, but it didn't work and probably barely effected his sleep score. While many critics will point out how his personal flaws detract from his overall philosophy (telling his followers to dopamine detox while sleeping with multiple women for example) they cannot deny that it is impressive and WE would likely all do the same in his position if given that status.

The book contains a good summary of protocols from his podcast over the years and is split into sections related to sleep, nutrition, exercise, learning and mental health. The advice is pretty basic: get sunlight, go to bed on time, exercise, eat your vegetables, etc and it really is the stuff your parents would have told you to do when you were a kid if they actually loved you. The true value is the detail and explanations why these things work. This kind of information does come across better in a book than his podcast I found because its easier to reference back and you really can only listen to so many podcasts about sleep before you realize this dude has just been yapping for three hours just to tell you the same thing he said in the last episode and you begin to fall asleep yourself.

Overall the book is pretty basic but solid. A huge missed opportunity to talk about relationships because I would love to see his autistic optimizing protocol mentality when it comes to dating given his credentials and success but the rizz and bedroom protocol probably could warrant a whole separate 300 page book.

I've waiting for "Protocols" approx 15 months, maybe even more. Initially I though it was going to be released Sept 2025, but then to my dismay I've learned that it's actually Sept 2026 ... I got encouraged by Huberman's podcast and recommendation from some people who told my that if I like Attia (his book on longevity was totally awesome), I should go for it.

So, here it is, but I rated it 3 - why so?
1. Let me start with what I liked here most - the "protocols" themselves - short, simple, universal "recipes" that pretty much everyone can apply: the best, the most actionable summary of the chapters one could imagine. They are clear, they are sound, they make sense.
2. The chapters are dedicated to varying topics - VERY varying: starting with sleep or food (understandable), and ending with ... light, stress control and personal growth (hmm ... sounds ... very personal & not always like a strict science). You'll probably enjoy some of them, but some you'll find not-so applicable.
3. Huberman mentions some commercial products and even recommends some of them, but he always says explicitly if he's in any collab with producers - that's a pro.
4. My biggest issue is that contrary to Attia's book or "Why we sleep" ... I've barely learned anything here. And the stuff I did (e.g., about light - I'm a bit skeptical about). So this book is quite good when it comes to reinforcing my knowledge and commitment regarding healthy nutrition and good sleep, but that's pretty much it. No game changer, no wow effect - just a good reference source I will reach to frequently (probably).

Solid 3/5, but I've expected something better.

[Rory Saunders · Rating 4 out of 5]

I am not a podcast guy. I like fitness and health hacks, but god knows I'm not going to sit through 3 hours on the microbiological effects of saffron or whatever. I had been recommended Dr. Huberman ad nauseam by friends and colleagues, but had not found a good way to approach his content. This book resolves that; it seems to condense all of his podcasting and website advice into a single, definitive source that can be easily referenced.

The book itself is great. I found his writing style to be engaging, and the chapters to be interesting. I read it from cover to cover in about a week, excluding the references of course. The tips are relatively easy to implement, the scientific backing is robust, and the book is well organized.

There are a few things that keep it off of a 5 star read for me:
1. It's very, very repetitive. I understand that it is meant to be used as a reference book, so each chapter has to stand for itself more or less, but my god you will read some sentences upwards of 20 times if you read the book sequentially.
2. If you did all of these things, you wouldn't have enough time to hold down a job, maintain a relationship, have children, etc. You definitely have to be selective about how you approach these protocols. If you don't, you'll be the healthiest, loneliest, and poorest person on earth.

[Bea · Rating 3 out of 5]

This book has too much information for me. The advice is backed up by loads of details, which I thought made it cumbersome to read. Maybe if I just kept the book around to look up particular issues it would be very useful. Most of the advice isn't new to me (eat less sugar, limit time on screens, exercise more), but if you like to read why, you will get all the chemical reactions and other scientific evidence you need.

[Michelle Fraley · Rating 2.5 out of 5]

2.5 ⭐️ rounded up. As a therapist and coach, much of this information seemed basic and redundant and Huberman is so long winded - the book was much longer than it needed to be. Of course, I cannot fault his research - he does go above and beyond and gives all the facts. Just felt a bit overdone for me. However, my low rating mainly comes from the nutrition and exercise chapters. I understand he is basing his protocols on science, but the protocols he offers are so structured and rigid, it would be difficult for the average person to stick with these protocols for diet and fitness. I wish books like this gave helpful habits and tips for regular people. Not people who do all of their shopping at Whole Foods and only eat non processed foods and have the financial resources to eat in this way. Also, the way he talked about food was just kind of a drag. Seemed like such a boring way to live honestly. The exercise protocols also seemed super rigid with the weekly program for strength and cardio that was totally set in stone - again, just seemed like this chapter was setting the average person up for failure. I’ve been helping people with behavior change for such a long time that I can tell you as a clinician that this is the type of book that people will read or listen to, and generally not follow through with…. It’s just far too inflexible to be practical. Oh…and the amount of time he spent talking about light exposure was enough to make me stare directly at the sun. Lol ok, we get it. Seeing sunlight in the morning is helpful.

I'm only two hundred or so pages in but I'm finding this book to be helpful. There's lots of in-depth information with plentiful citations from the literature. I'm finding it helpful to bounce around a bit and read deeply about the subjects I'm particularly interested in.

The book is well organized and it's helpful to have a juxtaposition between the science and Andrew's personal experience. I imagine I'll be working through this one for a while, but really happy to have such a practical compendium on my bookshelf.

[Trent · Rating 4 out of 5]

Thank you to Simon & Schuster Canada, the author and NetGalley for providing me with an ARC in exchange for an honest review.

A simple, yet effective book on improving various aspects of your overall health. Huberman presents evidence as to WHY you should consider following these tips in an easily digestible manner. One thing that surprised me was the transparency found in this novel, Huberman wasn’t afraid to share his partnerships with brands, when there wasn’t enough data to support a full conclusion, or even answering frequently asked questions directly in each chapter.

This is a book I’m certain I will be referring back to when needed.

[Amrita Kohli · Rating 1 out of 5]

Can’t trust a man who says their take on veganism / plant based diet is “I have vegan friends so I know it can work”… like fucking educate yourself on a topic you’re gonna write about. Comparing beans and rice to animal based protein sources is idiotic when there’s tempeh, seitan, TVP, etc.

Author is clearly biased and refuses to educate themselves fully and ignores the cardiovascular / harmful effects of an animal-based diet in the name of protein. Has no credibility on the topic of nutrition as well as several topics in this book

[louis barrette · Rating 1.5 out of 5]

Really wanted to like this :/ each chapter of the book was shallower than the knowledge i came in with - for sleep, this is an inadequate subset of Why We Sleep, for exercise and nutrition, the messaging is more one of personal experience than one based in science (and is still shallow for a guy like me who runs and lifts already), and the other sections also felt obvious. The book also suffers from a lot of repetition across the chapters.

2.5/5

[Teresa · Rating 3 out of 5]

Dr Huberman needs a protocol for brevity. There is far too much repetition in this book, even within the same protocol points are laboured to death and many of them have nothing new to say. Disappointing.

[Jasper · Rating 4 out of 5]

3.5/5.
It was pretty motivating and I learnt a fair few things, particularly in the middle chapters.
However, I felt like every protocol was longer than it needed to be (except for the exercise ones in chapter 2) and the audiobook sound quality was poor for some reason.

[The Bookish Elf · Rating 4 out of 5]

Within an hour of waking, go outside and get daylight into your eyes. Ten minutes if the sky is clear, roughly twice that if it is partly cloudy, half an hour if it is heavily overcast. Not through a window, not through sunglasses, not under a brimmed hat, and never by staring at the sun itself. If you wake before dawn, sit near a bright lamp until it rises. That is the first instruction in Protocols: An Operating Manual for the Human Body by Andrew D. Huberman, and it shows you exactly what kind of book this is: a manual that gives you the minutes, the conditions and the exceptions, then spends several pages explaining the cells in your retina that make it work.

How An Operating Manual for the Human Body Works

Huberman is a Stanford neuroscientist whose podcast, Huberman Lab, became one of the most listened-to health shows in the world. This book distils that catalogue into seven chapters: sleep, exercise, stress control, nutrition, light, focus and learning, and personal growth. Together they hold forty-seven protocols, ranked within each chapter by impact.

Every protocol follows the same template. A box of bolded steps tells you what to do. A section explains the physiology behind it. A question-and-answer section handles the objections readers actually raise, such as what to do on a cloudy day or whether a late espresso really matters. You can read it cover to cover, but it is built to be dipped into, and the steps are skimmable in seconds.

The introduction is part memoir. Huberman grew up around physicists, spent his teenage years skateboarding through some rough scenes, and found his way into neuroscience through a college lecturer who made the brain feel urgent. The most charming story belongs to the exercise chapter: at sixteen he cold-called the bodybuilder Mike Mentzer, who rang back, coached him by phone for months and charged him most of his savings for the privilege.

The nutrition chapter is the clearest example of the method. Instead of a named diet, Protocols: An Operating Manual for the Human Body by Andrew D. Huberman offers a ratio: how much complete protein a food delivers per calorie. Chicken and scallops sit at the top, beans and rice near the bottom, and grains and nuts are reclassified as carbohydrates and fats rather than protein sources. From there come plate thirds of protein, vegetables and starch, at least nine-tenths of food unprocessed, a modest fruit allowance and one treat a week. He refuses to call sugar poison and argues that eating windows work mainly by cutting calories, which puts him on the sensible side of several diet wars. Not every reader will accept his protein target of a gram per pound of body weight, which sits above what most research says muscle needs.

What Protocols: An Operating Manual for the Human Body Gets Right

The quiet thesis of Protocols: An Operating Manual for the Human Body by Andrew D. Huberman is that the most powerful levers are free. He says plainly that no pill replaces sleep, exercise or stress control, and he usually offers the zero-cost version of a tool before the device.

What works
The numbers are real numbers. A bedroom at 65 to 68°F. Caffeine stopped eight to ten hours before bed. A weekly training split of three lifting days and three cardio days with set ranges, rest times and heart-rate formulas. Very little is left vague.
The sleep chapter is the book's backbone. Fifteen protocols, built on Huberman's own field of circadian vision science, explain why light timing, temperature and consistency matter. Anyone fighting sleep deprivation will find a usable plan here before they reach a single supplement.
He admits gaps. He concedes that his famous advice to delay morning caffeine has no clinical trial behind it, that supplement studies are small and conflicting, and that rest techniques do not replace sleep. That candour is rarer in this genre than it should be.
Conflicts are disclosed. The front matter states he is a paid advisor to AG1, Eight Sleep, Function Health, Reveri and WHOOP, and he flags financial ties again at the point of use.
Where the Operating Manual for the Human Body Gives Ground
Weak evidence still gets strong language. The tone of Protocols: An Operating Manual for the Human Body by Andrew D. Huberman is confident throughout. Some scientists have criticised his podcast for overselling thin findings, and the book is better than that reputation suggests, but not immune. Mouse studies, single small trials and correlational cohorts are sometimes narrated as settled. The sleep chapter's claim that chronotypes split neatly into three equal groups, and the exercise chapter's insistence on taking every working set to failure, are stated with more certainty than the research supports.
The commercial ties are disclosed but not neutralised. Products he advises, part-owns or helped design turn up inside the recommendations. Disclosure is honest. It does not make the conflict disappear.
It is long and repetitive. More than five hundred pages of main text, frequent repeats of the same rules, and an admission at the start of one chapter that its first three protocols largely re-run earlier ones. The editing shows strain elsewhere too: the exercise chapter promises five protocols and delivers four, and a promised sugar-craving tool never arrives.
The notes are vast but uneven. Roughly eleven hundred endnotes, mostly peer-reviewed, sit alongside his own podcast episodes and lower-tier open-access journals. It reads as a bibliography assembled to support claims rather than a weighing of them.
Read It If / Skip It If

Who gets the most from Protocols: An Operating Manual for the Human Body by Andrew D. Huberman, and who should pass:

Read it if:

You want a single reference shelf for sleep, training and focus, with exact numbers.
You already follow the podcast and want the essentials organised and searchable.
You prefer to understand the mechanism before you change a habit.

Skip it if:

You want a short, simple plan; this is a reference work, not a weekend read.
You need advice for a diagnosed medical condition, which this is not. Talk to your doctor before trying the supplement or drug sections.
You are wary of health advice from someone with product ties, however well disclosed.

Worth Your Shelf

As a reference, yes. Protocols: An Operating Manual for the Human Body by Andrew D. Huberman is the most organised, actionable version of his advice you will find, and its free core of light, sleep, training and calm is sound enough to change an ordinary week. Read it with a pencil and a little scepticism, start with the morning walk, and treat the supplement pages as the last chapter of the conversation rather than the first.

The sun is free. Most of what matters in this book is too.

[Theodora Girgis · Rating 5 out of 5]

This book was written for my EXACT personality type - it is a literal reference book for health, perfect for the Type A person who just wants to clearly understand what to do, how to do it, and what the science says.

I used to watch Andrew Huberman's videos over COVID then fell off the YouTube fitness scene for years, I've been in a real lifestyle funk lately though and when I saw that he was releasing his first book, I had it pre-saved and immediately began listening to the audiobook the day it was released. I finished listening to all 18 hours in exactly one week over my long (and miserable) commute + daily dog walks. Huberman has a great voice, so it was easy to stay focused. On top of that, I appreciated the content so much that I've now also bought a physical copy of the book to easily reference in the future (despite it being a THICK book and me having ZERO space left on my bookshelf... oops).

The book is split up into seven sections: 1. Sleep, 2. Exercise, 3. Stress Control, 4. Nutrition, 5. Light, 6. Focus, Motivation, and Learning, and 7. Personal Growth. All important things that I've been struggling with lately. I've seen some reviews and articles that describe the tips as way too overwhelming and full of recommendations for (expensive) products from Huberman's many sponsors. As a perfectionist and a completionist, I also felt overwhelmed trying, at first, to FIX my life all at once and I do agree that the frequent "sponsored product" plug could be off-putting at times (sorry Andrew... I'm not inclined to spent $125 on blue + green light blocking glasses right now), but something that Huberman emphasizes in his introduction and repeats throughout the book is that you're not meant to take everything in the book and change your whole life or even follow it down to a T. Rather, he wants the book to serve as a catalogue of recommendations. Struggling with your sleep lately? Look through the listed protocols and implement one of them. Do some self-experimentation. Find what works. Adopt it as part of your lifestyle. Move onto the next thing. Same goes for nutrition, stress, focus, etc. If you are constantly seeking to improve your wellbeing, there will always be something else you can try.

Since listening to the book, my biggest lifestyle shifts have been around sleep, light exposure, and exercise. I've started using my 10,000 lux happy light (which I got during my COVID seasonal depression) again in the mornings and its really improved my ability to feel awake and not miserable when the day starts. I've also cracked down on my evening phone use (it helps that my phone is on its last legs and the battery doesn't last longer than an hour at a time anymore lol) and I started using a warmer coloured lamp rather than overhead bright lights in my room once the sun has set outside - both tips have definitely improved my sleep quality. The biggest shift for me has been exercise - I've been walking every chance I get and I started doing my strength training in the mornings rather than after work which has helped with my motivation, consistency, and sleep. Another thing, which I hadn't thought of much before, has been breathing - when I'm stressed or anxious, the physiological sigh is now my go-to breath technique to immediately calm down, and when I'm unfocused, a few deep diaphragm breaths can usually help me lock in again.

There's a lot more that I can and will do, but I'm taking it one step at a time. Do I feel like my life has been fixed? No, very far from it. But I do feel a bit less directionless now that the engineer in me has finally found an operating manual for myself.

This book is straight up amazing! To feel the author’s deep love for science and to bask in his incredible knowledge was the best reading experience.

I was listening and then having to write so many notes I just bought the book on iBooks so I could highlight effectively.

The book goes through an incredible list of things we can do to improve our sleep, our health, our function and our longevity.

Ranging from hydrating effectively to the best nutrition, exercise to light therapy, focusing on our learning and growth. The author backs all of these with science.

I highly recommend this one for anyone who likes to read about becoming more healthy.

I’m not a scientist so can’t vouch for everything in the book, however, it seemed very well researched. There are several things outlined in this book that I will incorporate in my every day life with hopes of improving my health and cognitive function.

[Matthew Morris · Rating 2 out of 5]

This book is kind of wellness/"life hacking" slop, generally I do not like that he continues to tout his own branded products despite his disclaimers, I find him to be talking too much in his own voice and overlaying his own opinions in a casual manner, and really the book seems to be a lot of .... fluff. I know this is probably to make it read for a larger audience, but it reads as cheap advertising rather than a thoughtful book.

[Steven L · Rating 5 out of 5]

Below are my notes (for Littler Books). I hope you find them helpful.

1. A protocol is a science-based formula designed to help overcome common obstacles or achieve a specific health or performance goal. Each protocol is grounded in physiology and is meant to take the minimum time needed to produce the greatest results.

2. No pill can replace exercise, sleep, or proper stress control. Even drugs that allow for neuroplasticity will not produce learning on their own.
a. "... better living through chemistry still requires better living."

3. Treat personal experience as data. Test protocols and note what happens when they stop.

4. Sleep is the foundation of mental health, physical health, and performance. Sleep deprivation has been linked to elevated risk of heart disease, stroke, hormonal imbalances, obesity, cancer, depression, and age-related dementia. The goal is to sleep well 90 to 95% of nights.

5. Sleep Protocol 1: View Sunlight as Soon as Possible After Waking.
a. Get morning sunlight in your eyes for five to ten minutes (longer on cloudy days) within the first thirty to sixty minutes of waking. This sets the suprachiasmatic nucleus (SCN), the master circadian clock, which coordinates every cell in the body to a 24-hour rhythm. Morning sunlight activates intrinsically photosensitive retinal ganglion cells (ipRGCs) that signal the SCN. This works even on cloudy days because ambient daylight is still far brighter than artificial indoor lighting.

6. Sleep Protocol 2: View Sunlight in the Late Afternoon.
a. Viewing late-day sunlight helps buffer against the negative effects of artificial light at night by reducing the sensitivity of retinal circuits. Morning and afternoon sunlight act as bookends that stabilize the circadian clock.

7. Sleep Protocol 3: Avoid Viewing Bright Lights in the Final Hour Before Bedtime.
a. Bright artificial lights emit a disproportionate amount of short-wavelength light that suppresses melatonin and spikes cortisol (stress regulator) at night. It also activates the perihabenula (a brain structure linked to depressive feelings), next-day anxiety, and learning deficits. Try dimming lights, using amber or red bulbs, wearing blue-and-green-light-blocking glasses, or using candlelight.

8. Sleep Protocol 4: Find Your Ideal To-Sleep and Wake-Up Times.
a. Chronotype (morning lark vs. night owl) is genetically determined.
b. Most people need seven to eight hours of sleep.
c. Consistent timing matters: the sleep cycle alternates between non-REM stages (N1, N2, N3) and REM in approximately 90-minute cycles. Deep slow-wave (N3) sleep predominates early in the night, while REM sleep (critical for emotional processing and memory consolidation) predominates in the final hours before waking.

9. Sleep Protocol 5: Lower Your Core Body Temperature at Night.
a. A drop in core body temperature initiates drowsiness. A hot bath or shower before bed paradoxically cools the core by drawing blood to the skin's surface, where heat dissipates. Keeping the bedroom cool (around 65–68°F) and sticking bare feet out from under blankets helps.

10. Sleep Protocol 6: Increase Core Body Temperature Before Waking.
a. Warming the body in the final one to two hours of sleep supports the transition through REM-enriched sleep cycles and helps to wake up feeling refreshed.

11. Sleep Protocol 7: Nap Correctly.
a. Short naps (15 to 20 minutes) boost focus and energy. Even brief naps enter N2 sleep, which helps to process learning and prepare the brain for more. Longer naps (up to 90 minutes) can help process heavy emotions via REM sleep, but naps beyond 90 minutes can mess up the circadian rhythm.

12. Sleep Protocol 8: Use Non-Sleep Deep Rest (NSDR).
a. NSDR is a self-directed relaxation technique. It involves long-exhale breathing and systematic shifting of attention across the body. Unlike naps, NSDR keeps the sympathetic nervous system partially engaged, producing a unique brain state where parts of the brain enter sleep-like states while others remain alert. NSDR restores mental and physical energy, reduces cortisol, and can improve nighttime sleep quality.

13. Sleep Protocol 9: Consider Supplements.
a. Try behavioral tools first. If supplementing, a commonly effective stack is magnesium L-threonate (145–250 mg), apigenin (50 mg), and theanine (100–200 mg), taken 30 minutes before sleep. Other options include glycine, GABA, myoinositol, and low-dose melatonin (
0.5–
1.5 mg). Always consult a physician.

14. Sleep Protocol 10: Approach Prescription Sleep Drugs with Caution.
a. Most prescription sleep medications create sedation rather than true sleep. They can suppress the natural sleep architecture of N3 and REM stages.

15. Sleep Protocol 11: Adjust Your Caffeine Schedule.
a. Caffeine blocks adenosine (a chemical that builds up when awake) receptors, masking sleep pressure. Its effects can last many hours. Avoiding caffeine in the eight to twelve hours before sleep can improve sleep quality. Delaying morning caffeine by 60 to 90 minutes after waking may help reduce afternoon energy crashes.

16. Sleep Protocols 12–14: Avoid Alcohol, Cannabis, and Late-Night Screens.
a. Alcohol reduces deep sleep and REM, even when total sleep duration seems adequate. THC potently reduces REM sleep and should not be used as a sleep aid. Screen use before bed delays sleep onset and fragments sleep via both light exposure and arousal from content.

17. Sleep Protocol 15: Avoiding Jet Lag.
a. Strategies include shifting light exposure, meal timing, and exercise to align with the destination time zone before and during travel.

18. Exercise Protocol 1: Walk as Much as Possible Each Day.
a. Walking 8,200 or more steps per day has a preventive effect against obesity, sleep apnea, gastroesophageal reflux disease, and major depressive disorder. Walking activates the enzyme AMPK, which stimulates glucose uptake into muscle cells, generates mitochondria, counters inflammation, and improves vasodilation.
b. A post-meal walk of even five to ten minutes lowers blood glucose more effectively than walking before a meal.
c. Walking induces optic flow (the visual image of the world moving past us) which triggers lateral eye movements that reduce activity in the amygdala (the brain's threat-detection center), thus lowering stress and anxiety (this benefit requires looking ahead, not at a phone).

19. Exercise Protocol 2: Resistance Train Three Times per Week.
a. A foundational template alternates three resistance training sessions and three cardiovascular sessions across seven days. Each resistance session targets specific muscle groups with compound (multi-joint) and isolation (single-joint) exercises taken to failure. Compound exercises mimic real-world movements, challenge the core, and trigger positive systemic hormonal effects. Isolation exercises target specific muscles with less overall nervous-system stress.
b. Progressive overload (steadily increasing resistance over time) is essential for continued adaptation.
c. Workout duration should be about 60 minutes. Rep ranges can vary widely (five to thirty) as long as sets are taken to failure, but regularly using heavy weights (five to eight reps) alongside moderate loads ensures activation of different muscle fiber types.

20. Exercise Protocol 3: Do Cardiovascular Training Three Times per Week.
a. Three sessions at different intensities target different adaptations. A long session (45–75 minutes at 60–70% of max heart rate, roughly nasal-breathing pace) increases the heart's stroke volume and stimulates fat metabolism. A moderate session (25–30 minutes at 75–85% of max heart rate) builds aerobic capacity and typically leaves a person feeling energized for hours afterward. A brief, high-intensity session (6–17 minutes of sprint intervals) pushes toward maximum heart rate, improves VO₂ max, and is the most metabolically demanding per minute of effort.

21. Exercise Protocol 4: Incorporate Mobility and Flexibility Work Two to Four Times per Week.
a. Brief sessions of stretching and mobility exercises help maintain range of motion, reduce injury risk, and support recovery from resistance and cardiovascular training.

22. The autonomic nervous system operates like a seesaw between the sympathetic (fight-or-flight) and parasympathetic (rest-and-digest) divisions. The goal is not to eliminate stress but to keep the response proportional to the stressor and to recover quickly.

23. Stress Control Protocol 1: Physiological Sighs.
a. One to three double inhales through the nose followed by a long exhale through the mouth can reduce stress in real time. The double inhale reinflates collapsed alveoli in the lungs, maximizing the surface area for carbon dioxide removal. The extended exhale slows the heart.
b. A lab study of 108 participants found that five minutes per day of cyclic physiological sighing produced notably bigger improvements in mood, resting heart rate, and sleep than box breathing, cyclic hyperventilation, or meditation.

24. Stress Control Protocol 2: Deliberate Cold Exposure.
a. Uncomfortably cold water (40–50°F) for one to three minutes, three to seven times per week, raises the stress threshold over time.
b. There are two phases: the acute state shift during immersion (a large adrenaline release one learns to regulate through calm, deliberate breathing) and a prolonged post-immersion shift (elevated dopamine lasting several hours). Regular practice trains the ability to stay calm under stress more broadly.
c. Cold exposure should be avoided within six hours after resistance training, as it can blunt hypertrophy and strength gains.

25. Stress Control Protocol 3: Non-Sleep Deep Rest (NSDR).
a. NSDR replenishes mental and physical energy, offsets many negative effects of sleep deprivation, improves nighttime sleep depth, and buffers against both acute and chronic stress. During NSDR, parts of the brain enter sleep-like states while other areas remain alert, and cortisol drops. NSDR can work the first time, and every time, unlike meditation, which requires regular practice to build up.

26. Stress Control Protocol 4: Micro Meditation Upon Waking.
a. A five-minute meditation done before getting out of bed each morning builds resilience by training the ability to observe stress without reacting. Research shows that people's anxiety actually increases during the first week of a meditation practice, because forcing focus when the mind wants to plan is itself a form of stress exposure. Over time, regular meditation reduces reactivity to real-life stressors.

27. Stress Control Protocol 5: Boost Your Morning Cortisol and Catecholamine (fight-or-flight chemicals) Peak.
a. A steep morning cortisol peak prepares the body for the day's stressors and helps keep cortisol low at night. Tools that raise morning cortisol include viewing bright light (can boost cortisol by 50%), caffeine, moderate to intense exercise, and deliberate cold exposure. Grapefruit and licorice root extract (containing glycyrrhizin) extend cortisol's duration through enzyme inhibition.

28. Stress Control Protocol 6: Supplements for Stress.
a. Several supplements can help offset excessive stress when used alongside behavioral tools. Ashwagandha (300–600 mg daily) can lower cortisol but should be cycled (no longer than a month at a time). Theanine (100–200 mg) promotes relaxation without sedation by increasing GABA. Phosphatidylserine (100–200 mg in the evening) may preferentially reduce nighttime cortisol. Rhodiola rosea (100–240 mg) reduces perceived fatigue and burnout symptoms, and has been approved in Europe for short-term stress relief.

29. When it comes to body weight, how many calories we eat relative to how many we metabolize matters (CICO/calories in, calories out). GLP-1 agonist drugs confirmed this principle at scale.

30. Body composition (the ratio of lean mass to body fat) affects health and longevity.
a. More than 70% of Americans are overweight.
b. The recommended approach is the "Clean Omnivore Diet”.

31. Regarding meal timing, intermittent fasting can help people eat fewer calories overall, but when matched for total calories against unrestricted eating, results are the same.

32. Not eating within two to three hours of bedtime appears to improve sleep quality, growth hormone release, and next-morning glucose regulation.

33. Nutrition Protocol 1: 90% or More of Food Should Be Unprocessed or Minimally Processed.
a. Eat single-ingredient, non-processed foods: e.g., meat, fish, eggs, fruit, vegetables, rice, lentils, beans, oatmeal, pasta, olive oil, avocado oil, and butter in small portions.
b. Avoid ready-to-eat packaged foods and packaged multi-ingredient foods. Most pre-packaged sauces and condiments contain added sugar.

34. Nutrition Protocol 2: Stay Hydrated.
a. Proper hydration supports digestion, nutrient transport, cognitive function, and physical performance. Dehydration impairs focus and energy.

35. Nutrition Protocol 3: Eat High CP:C Ratio Protein at Each Full Meal.
a. Protein sources with a high caloric protein-to-calorie ratio help build and maintain lean mass and promote satiety without excess caloric intake.
b. Animal-based: poultry, lean red meat, fish, shellfish, whey protein, eggs, plain full-fat Greek yogurt, and cottage cheese.
c. Plant-based: beans and rice eaten together, lentils, soy, seitan, and some grains such as quinoa.

36. Nutrition Protocol 4: Choose Fibrous Vegetables and (Some) Fruit as Major Carbohydrate Sources.
a. Fibrous vegetables (dark leafy greens) and fruits provide essential micronutrients and fiber while keeping blood sugar levels more stable than processed carbohydrates.

37. Nutrition Protocol 5: Consume Healthy Fats as Part of Most Meals and Snacks.
a. Healthy fats from sources such as olive oil, avocados, nuts, and fatty fish support hormone production, brain health, and satiety.

38. Nutrition Protocol 6: Consume Low-Sugar Fermented Foods.
a. Low-sugar fermented foods (such as sauerkraut, kimchi, and certain yogurts) support gut microbiome diversity and reduce inflammation.

39. Nutrition Protocol 7: Consume Fatty Ocean Fish and/or Consider Omega-3 Supplements.
a. Omega-3 fatty acids, particularly EPA and DHA from fatty fish or supplements, support cardiovascular, brain, and immune health.

40. Light is as crucial to health as sleep, exercise, or nutrition. Photobiomodulation (the use of specific wavelengths of light to influence biological processes) has been shown to treat acne, accelerate wound healing, promote hair growth, reduce pain, improve blood sugar regulation, offset age-related vision loss, and improve hormone health. Sunlight can be medicine.

41. LED lighting, which has largely replaced incandescent bulbs in the past decade, emits a disproportionate amount of short-wavelength light. Emerging evidence points to negative effects of LEDs on mitochondrial health and retinal cells. Incandescent lighting interferes with melatonin production far less often than LED or fluorescent lights.

42. Light Protocol 1: View Bright Light in the First Hour After Waking.
a. Morning bright light viewing can boost cortisol levels by up to 50%. This reinforces the circadian signals described in Sleep Protocol 1 and elevates daytime alertness, mood, and focus. If sunlight is unavailable, a 10,000 lux artificial light can substitute.

43. Light Protocol 2: View Sunlight in the Late Afternoon/Early Evening.
a. This reduces retinal sensitivity to artificial light at night, partially buffering against the circadian-disrupting effects of screens and indoor lighting after dark.

44. Light Protocol 3: Avoid Viewing Bright Light One Hour Before Bedtime.
a. This reinforces Sleep Protocol
3. Bright light at night suppresses melatonin, spikes cortisol, and activates brain circuits associated with depressive feelings.

45. Light Protocol 4 : Expose Skin to Sunlight During the Day.
a. Sunlight reaching the skin triggers biological pathways distinct from those in the eyes. UV light stimulates vitamin D production, and exposure to longer wavelengths of sunlight supports mitochondrial health in skin cells. Check the UV index to manage exposure safely.

46. Light Protocol 5: Expose Skin and Eyes to Long Wavelength Light (Red, Near-IR, and Infrared).
a. Long wavelength light (600 nm and above) penetrates tissue and supports mitochondrial function by enhancing ATP (Adenosine Triphosphate/cell energy) production in cells. Practical sources include sunlight (when UV is low), red-light panels, and incandescent long wavelength light devices. Sessions of ten to thirty minutes, three to seven days per week, are suggested. It can improve signs of skin aging, acne, wounds and glucose levels.

47. All sustained behavioral and cognitive change is the result of neuroplasticity -- the rewiring of neural circuits. The process for deliberate learning is called self-directed adaptive plasticity (SDAP), which follows a strict sequence: get alert, get and stay focused, maintain a state of urgency, embrace errors, rest, and repeat. The early stages of focus and learning are meant to include agitation (limbic friction), which signals that the brain is being asked to change.

48. Adaptive plasticity (learning) takes effort and reverts easily at first, while maladaptive plasticity (e.g., from trauma) occurs fast and is hard to undo. Plasticity in adult humans is almost exclusively the consequence of changes to existing circuits, not the addition of new neurons.

49. Learning Protocol 1: Shift into a State of Alertness and Focus.
a. Alertness is a precursor to focus. Tools for achieving it fall into foundational (sleep, hydration, nutrition), behavioral (removing the phone from the room, exercise, proper breathing, 40 Hz binaural beats), and pharmacological categories (caffeine, alpha-GPC, nicotine, prescription stimulants like Adderall and modafinil).
b. A study found that having a smartphone within physical reach, even zipped in a bag, reduces working memory and intelligence compared to when it is in an entirely different room.

50. Learning Protocol 2: Use Mental Contrasting to Achieve a State of Urgency.
a. Reframe motivation as urgency (a persistent internal state of readiness). The most reliable method to create this state is mental contrasting, a psychological tool that asks a person to imagine both their goals and the obstacles to achieving them in a structured way (WOOP: Wish, Outcome, Obstacles, Plan. Write an if-then statement for each obstacle).
b. The growth mindset (the belief that ability improves with effort) and stress-can-enhance-performance mindset can drive significant improvements in learning.

51. Learning Protocol 3: Embrace Errors.
a. Errors from genuine attempts are key signals that trigger plasticity.
b. The nervous system rewires largely based on what a person fails to do, not what they do correctly. Errors cause a release of neurotransmitters (acetylcholine and norepinephrine) that marks the relevant circuits for change.

52. Learning Protocol 4: Prioritize Sleep the Night After a Learning Bout.
a. Neural rewiring occurs during sleep, especially during REM sleep the first night after a learning bout. NSDR and brief breaks also consolidate learning.

53. Learning Protocol 5: Incorporate Micro Rests into Learning Bouts.
a. Brief pauses of about ten seconds, introduced at random intervals during practice, allow the brain to replay and consolidate newly learned material at a compressed speed.

54. Learning Protocol 6: Increase Retention with Mental Rehearsal.
a. Self-testing after a learning bout is the most effective way to protect new skills and information against forgetting.
b. A classic study found that one-time reading plus later mental reflection was far superior to repeated reading for both retention and comprehension. Underlining and highlighting only help if the person also late

Dave’s Summary

Andrew Huberman's book, “Protocols: An Operating Manual For The Human Body,” offers practical methods to improve health, energy levels, sleep, fitness, and mental well-being. His central argument is that small daily habits can help your brain and body function more efficiently. He describes how these habits have an effect on the body and explains why this is important. The book also includes clear steps which readers can put into practice in their daily lives.

A important habit is to get some natural light as soon as you wake up. Exposure to morning light helps to establish the body's internal clock, a system that controls sleep, alertness, and daily energy levels. Huberman also emphasizes the importance of drinking enough water and connects good hydration with an improved mood, sharper focus, and better physical health. He also mentions foods that promote gut health, for example those that are low in sugar and have been fermented. Making these choices can help the body remain in balance.

Sleep is one of the main topics in the book. Huberman says that sleep has various stages, each of which plays a part in the repair of both brain and body. The deep stage of sleep aids the body's recovery, whereas REM sleep helps the brain to organise and store important memories. He recommends sticking to a regular sleep schedule that matches your body's natural clock. A cool room, reducing the amount of light in the evening, and avoiding screens close to bedtime are also useful. He cautions that drinking caffeine and alcohol late in the day can be bad for your sleep, even though alcohol may seem to make it easier to fall asleep. Although short naps can help with concentration, long or late naps may make it more difficult to sleep at night.

The book also emphasizes the importance of carrying out some movement every day. Doing walks, having short walks after eating, and engaging in regular exercise can all contribute to better heart health, more effective control of blood sugar, and improved sleep. Huberman also advises people to focus on building strength and on moving their joints. He states that stress is a natural reaction of the body, but stress that continues for a long time can be bad for one's health. Brief meditation each day may assist individuals in coping with stress and in teaching their minds to remain calm. He also wants readers to be aware of the times when their thoughts move away from the task they are performing. By redirecting their attention to the present moment they can improve their mood and concentration.

Food is also a major element of the book. Huberman states that both the kind and the quantity of food are important. He recommends whole foods that have either little or no processing, for example meat, fish, eggs, fruit, beans, rice, and oats. He says that protein is useful for building and repairing body tissue; carbohydates and fats have their own useful functions as well, even though the foods we choose can influence our hunger, blood sugar levels, and heart health. He suggests reducing the intake of highly processed foods and refined sugar. He also makes it clear that weight change is determined by the balance between the number of calories consumed and the amount of energy used. An effective diet should promote health while at the same time matching a person's tastes, financial situation, and daily routine.

The main point of the book is to develop habits that support one another. Factors such as light, sleep, food, water, physical activity, stress management, and concentration all influence our mood and behaviour. Huberman provides readers with methods for testing these habits and discovering which ones are most beneficial for them. He also cautions against viewing each suggestion as a rule that applies to all people, since individual sleep requirements, meal plans, and daily routines can differ. The goal should be to make sensible choices that can be maintained in the long term rather than seeking out quick fixes.

Key Takeaways

Use the morning light to regulate your body clock; as soon as you wake up, go outside without looking directly at the sun, since this can help your body to know when to feel alert and when to get ready for sleep. It is also helpful to be exposed to outdoor light in the later part of the day and to have less bright light at night in order to maintain a regular sleep cycle.

Make getting a good night's sleep a daily aim and try to stick to the same sleep and wake times as your body's natural clock. You can help this by keeping the room cool, reducing the amount of time you spend on screens before going to bed and limiting your intake of caffeine in the late part of the day; although alcohol may make you drowsy at first, it can negatively affect the quality of your sleep and lead to a decrease in REM sleep.

Improve your health by eating the right foods and drinking water throughout the day. You should consume foods that provide the body with the essential nutrients it needs. Huberman prefers whole foods and recommends including fermented foods to promote gut health. He also advises reducing your intake of refined sugar and highly processed foods.
Change your location and work out your body. Walking, having short walks after eating, and doing regular exercise can all help with heart health, blood sugar control and better sleep. Exercises that build strength and involve the joints are also important. Making small amounts of movement during the day can help counter the effects of long periods of sitting.

Learn how to manage stress and to stay in the present moment; practicing meditation for a short period each day can help you develop calmness and concentration. Although stress may have a useful role, prolonged stress over a long period of time can be bad for your health. When you notice that your mind has wandered, return your attention to the thing you are doing without criticizing yourself.

Memorable Quotes

But the type of food we eat is probably second only to sleep and exercise for its importance to our long-term health. Centering our meal and snack choices on whole (that is minimally or non-processed) foods has so many benefits—disease prevention, longevity, cognition, mood, energy, reduced inflammation, healthy weight management, and more.

The increasing concerns about processed foods stem from the plethora of data linking them to obesity, high blood pressure, heart disease, gastrointestinal disorders, cancer, and other serious ailments.77 Chemical additives used to color, preserve, texturize, and flavor these products have been linked to potential health hazards.78 Processed foods also tend to contain high amounts of sugar, even in products that would seem to not require it. And excessive sugar consumption is tied to diabetes, heart disease, cancer, and an increased risk of early death.79 All of which is to say, we need to make it a point to eliminate, or at least vastly reduce, processed foods.

And there’s interesting data on diet sodas. In a randomized controlled trial from 2024, people who consumed diet sodas lost more weight than people who drank equivalent amounts of water.94 The underlying reasons include less hunger among soda drinkers and more cravings for sweetness among the water drinkers. At the same time, people who consume a lot of artificial sweeteners often experience increased overall appetite, perhaps due to glucose and insulin disruption.95 There isn’t a broad rule that applies to all artificial and low-calorie sweeteners. For some people, they seem to help with weight loss, whereas for other people, they stimulate hunger in ways that may make it harder to keep from overeating. You have to figure out which group you are in.

Protocols by Andrew Huberman — a practical guide to living better. ⭐⭐⭐⭐⭐

I love books that don’t just give you information but inspire you to take better care of yourself. Protocols is exactly that kind of book.

What I appreciated most is that Huberman explains the science behind everyday habits and offers practical ways to improve physical and mental performance, energy, focus, sleep, and overall well-being.

While reading, I was pleasantly surprised to realize how many of these habits are already part of my life:

* Regular exercise: CrossFit, swimming, cycling, running, and mobility are already essential parts of my routine.
* Morning sunlight and time outdoors: Between endurance training, horseback riding, hiking, and traveling, I spend plenty of time outside.
* Cold exposure: I practiced cold showers, including five-minute sessions during my 75 Hard challenges.
* Reading and continuous learning: Reading is a daily habit, and I genuinely enjoy challenging my brain and learning new things.
* Mindfulness and mental resilience: Long endurance sessions, challenging hikes, and deliberately doing difficult things have taught me patience, discipline, and mental strength.
* Nutrition and hydration: I pay attention to protein, whole foods, hydration, and fueling my body for training.
* Consistency: Perhaps the most important lesson of all. I’ve learned that lasting results come from what we do repeatedly, not occasionally.

Of course, the book also reminded me that there is always room for improvement, especially when it comes to prioritizing sleep, managing stress, and balancing recovery with ambitious training goals.

What I particularly liked is that Protocols isn’t about finding one magical solution. It’s about understanding how small, intentional choices can influence our health over time.

For me, this book was both an educational read and a reassuring reminder that many of the things I genuinely love doing are also investments in my future health.

Highly recommended for anyone interested in longevity, neuroscience, fitness, and becoming a healthier version of themselves.

[Anthony Parker · Rating 3 out of 5]

I didn't read the entire book—only the introduction and a few selected protocols from each chapter. The author explicitly states that readers should treat this like a manual and that reading cover-to-cover isn’t necessary, so I approached it exactly as intended.

In my opinion, it is a poorly written book that desperately needed a good editor. I usually use the introduction of a book to get into the right headspace for the upcoming chapters, but the opening is surprisingly self-indulgent. The author spends the first few pages clearly defining protocols and dismissing the concept of "biohacking," but then takes a massive, 15-page detour into a personal memoir. He details everything from his teenage skateboarding days and a 1994 Fourth of July street fight to his grad school sleep habits and the tragic deaths of his mentors.

Eventually, it circles back to explaining how to actually use the manual, but the way it jumps around completely breaks the flow. Because the pacing is so disjointed, it took me three separate attempts just to read and finish the introduction alone because I kept losing interest. I feel the manual approach was a bad concept. In my opinion, the chapters probably could have been consolidated into separate books. Compared to other books I have read recently, this is below standard. It is off-putting trying to read it—maybe it is the manual style; I kind of don't even want to use it. While the book contains an abundance of information, much of it is common knowledge.

This was one of the best books I’ve ever read.

I’ve had a lot of respect for Andrew Huberman for a long time. He has always been like a prophet to me in the world of science and I see this book as his holy book. (Joking of-course)

At first, I thought of Protocols as more of a reference book, something I would go back to whenever I was interested in a specific topic. But I also wanted to read it from beginning to end, like a story.

So I started reading it, and honestly, it was a little boring at first. I even started reading Red Rising at the same time, so I could switch whenever I got bored. But after a while, I found myself putting Red Rising aside (even though it’s one of my favorite books so far) just to keep reading Protocols.

For me, this book represents where we are in the age of science. After thousands of years of humans living on Earth, learning, and discovering things, this is what we know about ourselves so far.

Of course, science will keep moving forward. Some things might change, and maybe there will be a second version of this book someday. Until then i recommend this book to anyone.

[Kosta Galabov · Rating 4.5 out of 5]

it is very useful, and (at least for me) engaging and interesting book. Huberman's still is easy to follow, and if throwing some science-y :) terminology here and there, doesn't make it difficult to read.
Despite what few reviews I read say, no part of the book tells you to do or follow any of the "protocols" it discusses. Actually quite the opposite, Huberman goes out of his way to constantly remind his readers (and listeners) that all of these are there for them to pick and choose, and it is up to them what they want to follow if anything.
And the protocols are, by-and-large, small and logical things so it is not like one would feel overwhelmed (or at least I think so).

The only downside, and it is really minor one, is the tendency of Huberman going in a tangent to explain the "why" of a protocol. I am a curious person, and I like to know "stuff" (especially outside of my core expertise), and at some point I felt overwhelmed by the information on "why". I get it. Nowadays, one need to explain well what they talk about given the amount of misinformation elsewhere. And it is ok. It is a minor thing. All in all, highly recommended read.

I suspect all health books. Besides the author’s intentions, there are the trends and the framing. Therefore, such reads demand caution. Nevertheless, I always get something out of them.

Although the author gets into too many details that do not interest me, he reminded me of good practices (like getting a good night's sleep) and called my attention to obvious ones that I was not attentive to, like sunbathing.

This book is worth its weight in gold. NSDR, physiological sighs, morning light exposure, cold exposure, and much more can easily be implemented into your life with substantial benefits relative to cost. This is one of the most important books I've ever read and I will be pressing onto the people in my life that I want better for. I like Huberman's approach, and there is also lots of charming personal anecdotes that make the book even more enjoyable to read and explore.
