There are four simple sections and you can read them in random order. They are a bit academic but also quite accessible. The author has spent twenty years of his life studying the subject. He summarizes several academic studies about sleep in this book. By the end of the book, I realized that sleep is the universal health care provider. We sleep for 1/3 rd of our life. Bad habits early in life compound over time and can lead to several ailments. Here are some tips to a good night's sleep
- Sleep at the same time and wake up at the same time
- Have a nightly sleep time ritual
- Avoid coffee and naps after 2 pm
- Maintain a cool temperature before you get to bed
- Avoid technology and bright lights in the house in the evenings
- Get lots of natural light and movement through the day
- Meditate for a few minutes to calm your mind before you sleep
- Have positive associations in your head about sleep and your place of rest
- Don't stay in bed for more than 25 minutes if you are not getting sleep
