The 20 minute rule finally clicked after a bad 90 minute nap
I always thought longer naps meant better naps, but yesterday I slept through my alarm for an hour and a half and woke up with my head in a fog until dinner. A friend in my running group said the sleep cycle thing is real, so I set a timer for 20 minutes with my phone across the room. Has anyone else found that short naps actually leave you more refreshed than the long ones?
