Optimal Bedtimes

It takes the average human about 15 minutes to fall asleep. To wake up refreshed you should go to bed at one of the following times:

  • 10:45 PM
  • 12:15 AM
  • 1:45 AM
  • 3:15 AM
  • 4:45 AM
  • 6:15 AM

If you go to bed at one of these times, you should rise at the end of the 90-minute sleep cycles. A good night's sleep consists of 5-6 complete sleep cycles.
