Have you ever slept through ALL of your alarms after being absolutely certain that they were all set? The body has a great way of telling us when we need to sleep if it hasn’t gotten adequate rest.
One way to combat this is by ensuring that your sleep schedule follows through complete REM cycles which last on average 80 to 100 minutes.
If you try to time your sleep by approximate 90 minute intervals, you’ll have a much better sleep waking up at the end of an REM cycle as opposed to disrupting this cycle right in the middle.
Check out this handy sleep calculator for a more accurate measurement of when you should fall asleep to feel refreshed whether you get eight hours or four.
