Getting enough sleep is critical for good health, but the old advice about needing eight hours of sleep can vary by person. A better way to find your optimal bedtime is to conduct an experiment to find when you naturally wake up. Here’s how.
Dr. Michael Breus writes on the Insomnia Blog that to find your perfect bedtime, you should count back 7.5 hours from your typical wake time (the average person has 5 sleep cycles that last 90 minutes long, so that’s why we should start with 7.5 hours). If you wake up within 10 minutes before your morning alarm after three days, that’s your target bedtime.
If not, move your bedtime back by 15 minutes every three days until you do wake up just before your morning alarm.
Imagine waking up without needing the alarm clock—and getting the sleep you need. That is definitely worth this little experiment.
