Sleep cycles are 1.5 hr in length. So sleep for 6, 7.5, or 9 hrs
Count backward from when you want to wake by those cycles to know when to go to sleep
Shut off electronics 1 hr before sleep to allow the brain to relax
Naps, if taken are either 15 min or 1.5 hrs to fit a cycle
Sleep on your side with a full body pillow for the most spinal support
White noise, cooler room, and socks can help fall asleep faster
