A: This is an interesting question, because both Eastern and Western Medicines come to the same conclusion: do your best to be in bed by 11pm.

According to Eastern Medicine

The most important time to be sleeping is between 11pm and 3am.  This is the time when there is tremendous renewal and sleep is the deepest. They also consider this “Liver Time”. Isn’t that interesting? The liver manages stress levels.  This is why any of the formulas that help you to find better sleep always are good for both the liver and the central nervous system.  (Sleep Tonight, Calm Energy, Calm Spirit, Spirit Well Being).  And have you noticed? If you stay up past 12am you could stay up all night.  The Eastern explanation is that the liver has been overstimulated and it just can’t settle down.

Western Science

Has found that if we don’t get at least 5 90-minute sleep cycles there is sleep deprivation. If you get up at 6:30 that would mean you would need to be in bed by 11pm.  So you can see this is a place where East and West come to the same conclusion — a good night’s sleep is best to start by 11pm.

The wonderful benefits of a good night’s sleep:

  • You won’t overeat as much, lack of sleep overstimulates your appetite
  • You won’t get sick. The immune system builds its protective forces as you sleep.
  • You’ll feel better mentally and emotionally. Sleep deprivation feeds depression.
  • You’ll avoid disease without even knowing it. A good night’s sleep brings down inflammation.


Wonder if there is any flexibility in this rule? Maybe you need 15 – 30 minutes more or less sleep. How to tell? Here is a fun experiment to do to find out exactly the best time for Be in bed by 11 every night and see if in a week you start awakening within 10 minutes of your alarm. If you don’t, start going to bed 15 minutes earlier each night until that happens. If you do, then you can experiment in the other direction. Then you have your personalized formula for a great night’s sleep.
