Why We Sleep

by Matthew Walker

MORE IDEAS FROM THE BOOK

It all comes from the notion of circadian rhythm, which is simply your 24-hour rhythm. If we make it change constantly, by waking up at a different hour everyday of most of the days, it will not be able for our body to regulate our energy-levels.

  • It made me more aware of the importance of sleep
  • It made me realize how our society is priving us from enjoying better performance
  • It made me change my habits, now 7-9h of sleep for me are a must

This is one of my favourite books of all time, I have always known about the importance of sleep, but after reading this book, I started to take sleep really serious, making it the engine of my "productivity machine"

I think everyone should read it, it is definitely directed to everyone, since all of us has to conmute to bed every single day. Maybe, it is a great way to introduce yourself to health-related topics, the way the author explains the topic makes it accesible to all of us.

  • Sleep pressure: Every second you’re awake, a chemical called adenosine is compiling up in your brain. The concentration of this substance is increasing your desire to sleep
