Sleep is fundamental to our health and well being. In Sleep Sense, international sleep expert Dr. Katharina Lederle draws on the latest research to explore how sleep is connected to each of the three pillars of successful living: physical health, cognitive performance, and emotional well-being. And since the three pillars are interconnected, if one is weakened, our overall health can easily be undermined. The first part of the book takes readers on a tour of the most essential information for understanding sleep. How and where it is generated and regulated; why light is so important for sleep, and how sleep differs between the genders. It also touches briefly upon dreaming, highlighting that it is normal to dream and perhaps useful to reflect a little on what we dream about. The second part of the book looks in detail at how sleep affects each of the three pillars, explains sleep disorders, and sets out a ‘menu’ of healthy sleep options from which readers can choose in order to establish healthy sleep habits that best fit their life. The result is a book that both informs and educates as it sets out clear guidelines and practical advice on how you can achieve improved health through improved sleep.
Well written and easy to understand more about something very important for health in general. Learned quite a lot and sparked an interest to learn more about sleep. Have struggled with sleep (nightmares/ sleep hallucinations/sleep paralysis) for a long time but never really had an interest to learn more about it
Main takeaways: 1) The biological purpose of sleep is still not fully understood, but it's clear that it has to do with restoring both the body's immune system and the brain's memory stores 2) When we're short on sleep: - it's easier to catch colds and other diseases - we struggle with decision-making - simple motor functions become measurably less efficient 3) The more consistency we can achieve in our overall sleep patterns, the better we're able to recover from occasional lapses in sleep quality: a daily pattern of good sleep hygiene - getting out into the daylight, not eating late, respecting the sleeping space - helps provide a sleep credit store that we can rely on, even on those days we drop our best habits 4) To discover your natural rhythms, try forgoing alcohol, caffeine, and alarms for a week, and see what happens
Actionable advice: Maintain a strategic approach to your sleep-life: a) if you're up late, limit your lie-in to around an hour after your usual get-up time; b) aim for consistency over the year, not just the week. Your 'sleept debt' will even itself out.
Sleep is good. Bad sleep is bad. Helpful & simple. This was not a book on gender but it did explain gender differences in sleep and sleep disorders - and so I was again reminded of why a 30-day hormonal cycle is scientifically more annoying than a 24hr cycle. I mostly read it as a kick up the backside to just sleep better, and (to no ones surprise) 7-8hrs feels way better than 5-6hrs !
Nothing ground breaking in this book, though it can serve as a good reminder for what good sleep habits are and how to incorporate them into your life.
