Why We Sleep is the best book I have read on sleep. The author has beautifully summarized how important sleep is for our health. He writes the most difficult medical terms and phenomena related to sleep in such a simple and interesting way that a common reader can easily comprehend. 

In the final lines of the book, the writer gives the 12 tips for healthy sleep. These tips, you can say are the essence of the whole book. 


12 Tips For A Healthy Sleep From The Book: Why We Sleep

Go to bed and wake up at the same time every day. Sleeping later on weekends won’t fully make up for a lack of sleep during the week and will make it harder to wake up early on Monday morning. 

Set an alarm for bedtime just like you set up one for the morning. 

Often we set an alarm for when it’s time to wake up but fail to do so for when it’s time to go to sleep. 


A light snack is okay, but a large meal can cause indigestion, which interferes with sleep.

Drinking too many fluids at night can cause frequent awakenings to urinate.


Some commonly prescribed heart, blood pressure, or asthma medications can disrupt sleep patterns.

If you have trouble sleeping, talk to your health care provider or pharmacist to see whether any drugs you’re taking might be contributing to your insomnia and ask whether they can be taken at other times during the day or early in the evening.


Don’t overschedule your day. A relaxing activity, such as reading or listening to music, should be part of your bedtime ritual.



The drop in body temperature after getting out of the bath may help you feel sleepy, and the bath can help you relax and slow down so you’re more ready to sleep.


Get rid of anything in your bedroom that might distract you from sleep, such as noises, bright lights, an uncomfortable bed, or warm temperatures. You sleep better if the temperature in the room is kept on the cool side.

Having a comfortable mattress and pillow can help promote a good night’s sleep.

Turn the clock’s face out of view so you don’t worry about the time while trying to fall asleep.


Try to get outside in natural sunlight for at least thirty minutes each day. If possible, wake up with the sun or use very bright lights in the morning.

If you have problems falling asleep, you should get an hour of exposure to morning sunlight and turn down the lights before bedtime.


If you find yourself still awake after staying in bed for more than twenty minutes and you are starting to feel anxious or worried, get up and do some relaxing activity until you feel sleepy.

The anxiety of not being able to sleep can make it harder to fall asleep.
