jBrAD's things you didn't know

Why is 2 p.m. the best hour for increasing alertness?
At that exact hour of the day, melatonin (the sleep hormone) is at its highest level, making it an ideal time for taking a nap. A 20-minute power nap regenerates brain cells and energy levels, leaving you refreshed and alert. Just make sure to set a timer: anything longer than 20 minutes can shift the body into deep sleep--which, if interrupted mid-sleep cycle, can leave you groggier than before your shut-eye.
