Life Explained: Chasing 10Hz

by Izzy Justice

Every human being constantly seeks to understand and express their human experience.

Throughout history, we have relied on philosophy, psychology, religion, spirituality, and all forms of art as frameworks for making sense of life.

In Life Chasing 10Hz, Dr. Izzy Justice introduces a complementary framework grounded in neuroscience.

The brain is the primary instrument of all human experience. Electricity is the language of the brain.

After looking more than 18,000 times into the brains of people in the seconds leading up to moments when they wanted to perform at their best, Dr. Justice discovered something profound. There is an electrical frequency, 10Hz, where brain function becomes optimal and sensory input is amplified.

At 10

Presence naturally emergesFocus sharpensDecision-making becomes clearerThe brain retrieves the right information from what it already knows

This is not theory. It is observable brain activity.

When the brain is calm and regulated, it guides you toward the next best step. Under stress, cognitive overload, fatigue, or pressure, access to that clarity is reduced.

This book challenges the expectation that we must be perfect, happy all the time, or equipped with unlimited time and resources in order to be our best. It invites a different possibility.

That showing up as your best self in the moments that matter takes only seconds and uses only what you already have.

Your brain.
Your body.

From this perspective, performance, focus, stress regulation, sleep, and mental clarity can all be understood through the same lens. Regardless of the challenge, the starting point is the same.

Get to 10Hz.

Life Explained: Chasing 10Hz by Dr. Izzy Justice is a very interesting book that talks about something we all feel in daily life: stress and mental noise. Our brain in a constant state of stress. The book explains that many of us spend most of our time in a high-stress mental state because we are always thinking, worrying, checking messages, or trying to do many things at once. I could relate to this from my own experience. There are days when my mind feels very busy, like I cannot stop thinking about everything I need to do. When that happens, I notice that it becomes harder to focus or feel calm.

What sounded new to me was the idea of the 10Hz state, where the mind is calm but still alert. While reading the book, I started thinking about moments in my own life when I felt like that. When I am very focused on something I enjoy or when I take a quiet moment to breathe and slow down. In those moments, everything feels clearer and easier.

Life Explained: Chasing 10Hz offers a thoughtful and surprisingly practical look at how our brains respond to the nonstop pressure of modern life. From a reader’s point of view, the book feels refreshingly different from the typical self-help or motivation titles that promise change through sheer willpower. Instead, Dr. Izzy Justice explains that focus, calm, and performance are really about brain states, not personality traits. That idea alone can feel like a relief. The writing balances science with accessibility, so even readers without a neuroscience background can follow the concepts. Some sections may feel a bit technical, but they add credibility rather than confusion. What stands out most is how the book reframes stress and burnout as neurological responses rather than personal failures.
Overall, it’s an insightful, slightly nerdy but engaging read that leaves the reader thinking differently about attention, energy, and mental clarity in everyday life.

Lower the noise to hear life

After reading this book one idea stayed in my head for a while. Many times it is not that people do not want to do things well, the mind is simply too full. Work, the phone, worries… everything happening at the same time. The brain almost never really rests. It made me think that maybe doing better in life does not always mean trying harder, but learning to slow down a little.

In my case I notice it often. When I am calmer, almost without realizing it, I think better and decisions feel clearer. It sounds obvious, but strangely we almost never practice it.

The book left me with a simple thought. Taking care of the mental state matters almost as much as working hard. Sometimes stopping for a moment, breathing, or disconnecting for a while ends up helping more than continuing to run all day.

A great teaching
Honestly, I haven't read such an engrossing and interesting book in months like “Life Explained”. I was curious about it and after reading it I found a lot of answers to some of the queries that I had. Izzy Justice has experience in neuroscience and she explains the way people's brains work under stress and without it. Nowadays, people are in constant alert about everything, this alert together with stress, sleep deprivation or mental fatigue, affects the brain directly. So, along the pages Izzy shows ways to help people to optimize brain function, think clearer and work on stress regulation, among other important and interesting issues.
All in all, it's an excellent book to learn a bit more about how the brain works and what to do to boost it and understand your body and your brain. I highly recommend it.

We live in an extremely demanding world where it is often difficult to stay focused, where overload is constant, and stress is part of our daily lives. I have read several authors who address this issue and offer help, but I particularly liked this book because of its neuroscientific approach. When I first opened it, I mistakenly assumed that it would be difficult to understand given the technical nature of the subject. Nothing could be further from the truth. The author takes care to break down each concept and explain the more complex information.
Chapter eight had a profound effect on me, as I came to understand that adequate rest is essential for the brain to function properly. However, humans tend to live on the edge of collapse.

This is a book about the human brain. More specifically, it’s about how stress, sleep deprivation, and similar issues can impact how the brain functions. Not surprisingly, these can impact the brain in negative ways, and the body as well. After a section dealing with the negative factors that can impact the brain, what follows is one where the author explains how you can allow your brain to recover.

If you follow the author’s advice, then you can learn how to avoid negative and stressful factors and to embrace a healthier way of dealing with the world. Those who do should be a lot happier as they go through their day-to-day lives.

What if you learned that your drive and focus is not some innate personality trait, but the result of how your brain chemistry operates? What if someone told you that you can trigger these changes in your brain? This is exactly what Life Explained: Chasing 10Hz by Izzy Justice demonstrates! Based on neuroscience, Justice explains how the brain functions under stress and how we can make changes that allow it to thrive under pressure! This book is ideal for anyone who wants to improve their productivity, become a better leader, or recover from the burnout of a stressful, high-pressure situation. I am giving it a well-deserved five out of five stars.

I picked up this book for several reasons. I am very interested in neuroscience. In addition, the book promises to help with the stresses of life in the hectic modern world. The best part for me, however, is the part about sleep deprivation and how to rectify it.

Written in a clear and concise way, I find that this guide really covers everything about the workings of the brain. It helps me so much to know how to balance my life in a way that allows my brain to work at its best ability. The volume is extremely valuable for anyone seeking greater attention span, as I am. It covers so much more. I highly recommend it.

I have to confess something first. Anything related to the brain and how it works always fascinates me. So when I found this book, I was curious right away. This reading is not a typical motivational book. It goes more into the science of what is happening in the brain when we are stressed, tired or trying to focus. I really liked that everything feels well supported and explained. The author did serious work here.

I didn’t rush this one. I read it slowly over several weeks, just to really understand it and not get lost in the concepts. For me it was very interesting and thoughtful. I definitely recommend it if you enjoy learning about the brain and performance.

It's been a long time since I've read a book as interesting as this one. Author Izzy shares, in a dynamic way, how to reach our full potential despite daily demands. As time goes by, we increasingly lose concentration and focus, which is why this book is a must-have in every book shelve.

I really enjoyed this reading, which, besides being comprehensive, has various activities to do, which in my opinion are very helpful for facing daily life. I recommend this wonderful read to all those readers eager to reach their potential and enter the neuroscience world.
