Hi everyone!
In this newsletter edition, I want to take a moment and talk about sleep. Last week I reviewed my notes from the book Why We Sleep by Matthew Walker. Even though the book has received a lot of criticism (some of which the author addressed here), it changed the way I think about sleep. After the reading the book I did three things:
  • Limiting my caffeine intake to 1 cup of coffee in the morning. Caffeine has a half-life of 5-8 hours. Even with my limited caffeine intake, there’s still some caffeine left in my system by the time I go to bed.
  • I started viewing sleep as necessary and very important for my health. I aim to always get 8 hours of sleep, regardless of what’s going on in my life.
  • I practice the saying “sleep on it”. Research has shown that sleep is essential for learning & problem solving. Rather than staying up late to work on a problem, I trust that my brain will figure it out while sleeping. And sometimes that’s exactly what happens!
Sleep is vital for us (otherwise evolution would’ve gotten rid of it), and I think everyone should read this book (or a summary of it).
But enough about my obsession with sleep. Let’s get to the juicy stuff: random bits I found on the internet 😉.
Enjoy!
