Why We Sleep: Unlocking the Power of Sleep and Dreams

This book became my all-time favorite book after reading the first chapter. Mathew Walker is a world-class, textbook scientist. The one who CIA send a helicopter to pick up for a secret mission. Through this book, he patiently and scientifically explains many experiments and their jaw-dropping results (most of them conducted by himself and his research team).

Sleeping is 1/3 of our lifetime (if it is not then read this book!), which we have very little knowledge about it because we are sleep when we are sleep. What surprised me was the significant importance of sleep duration and quality on our mental health and performance and physical body.

Myth: 6 hours of sleep is enough for our body.

Mathew Walker proved it’s wrong. We actually need 8-8:30 hours of sleep. and ironically the last 1:30 hour of sleep that contributes the most to learn the skills we practiced during the day. This 90 minute is usually the portion we generously sacrifice because of staying up late night to watch a movie, lingering at parties, etc.

This book is one of those books that whenever you read it is late! and you wish have read it sooner!

Probably the most intriguing chapter of the book was about dreaming. And the most exciting one is how R. Cartwright showed that dreaming helps you to forget! Through an extensive experiment, she showed that among the people who went through painful experiences (emotional trauma, divorce, break ups, …) the group who expressly dreamed about the experience manage to get over it at a certain time (a year in her experiment). However, the group who didn’t dream about the experience still being dragged down by the strong undercurrent of depression that remained.
