Why We Sleep
Matthew Walker is a sleep scientist and in this book explores why we sleep and the consequences of getting less than your recommended 7-9 hours sleep a night. It is shocking to learn the damage even being an hour short on sleep a day will do to your immune system. Lack of sleep effects your ability to control your emotions and understand those of others, your memory, your creativity; it predisposes you to eat more and to put on more weight; and it is closely linked to ADHD for the young and Alzheimers for the old.
Basically, if you go on Twitter and think "why is everyone and everything so absolutely awful" it's probably related to society-wide chronic sleep deprivation that people don't even realise they have. Some of the more striking findings are the results of working night shifts and junior doctor rotas, the cruelty of early morning school starts, and the overwhelming carnage caused by tired drivers. As horrifying as the consequences of lack of sleep are, what is incredible to discover is the healing power that is available to us all - sleep!
