Posts Tagged ‘Optimal sleep hours’

WSJ has an article asking how much sleep do we need. Some experts argue that seven hours might be optimal, while others think we should sleep longer. As usual we should be skeptical about these findings. My guess is that it differs by person, and the quality of sleep is as important as the amount of sleep.

This might be a way to find out your optimal amount of sleep:

Experts say people should be able to figure out their optimal amount of sleep in a trial of three days to a week, ideally while on vacation. Don’t use an alarm clock. Go to sleep when you get tired. Avoid too much caffeine or alcohol. And stay off electronic devices a couple of hours before going to bed. During the trial, track your sleep with a diary or a device that records your actual sleep time. If you feel refreshed and awake during the day, you’ve probably discovered your optimal sleep time.
