Eli5: Why do we need to sleep so much, what happens in the body when asleep that cannot happen while normal resting or relaxing? Or is it just for the brain?
In: Biology
This question has a very long explanation which is answered by the book [why we sleep by Dr Matthew Walker](https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.amazon.co.uk/Why-We-Sleep-Science-Dreams/dp/0141983760&ved=2ahUKEwiw1-ntscjtAhXQVsAKHXctBnsQFjANegQIMBAB&usg=AOvVaw1cIRs7FtuFLbc6qVLTdbRS)
Seriously, every question you have about sleep including the one in this post is answered in this book. I was always a person who didn’t care about my sleep until I finished reading this book. I also HATED reading books and this was the first book I actually read by myself – I often found myself reaching for this book of I had a spare 10 minutes rather than my phone, I just thought looking at words on a page was boring… Until I saw how well written this book is.
This book isn’t just for people who are fitness conscious, this book is for ANYONE that wants to live a better quality life.
This book talks about a variety of topics surrounding sleep including: effects of chronic sleep deprivation/how technology and urban life affects our natural circadian rhythms/ effects on obesity and how adequate sleep impacts muscle building/ looking at indigenous tribes and civilisations that aren’t influenced by society and technology/mental health and cognitive health
