I read the headline of this Tweet and first thing I thought: I knew it!

According to sleep expert, David Dinges, the chief of the Division of Sleep and Chronobiology in Psychiatry at the University of Pennsylvania Perelman School of Medicine, said humans are biologically programmed to sleep at night, and to take a nap in the midafternoon, however scientists still aren’t sure why.

Dr. Dinges says, “There is no melatonin triggering the sleep, it just seems to be this harmonic phenomenon.” The consensus is that “human civilization evolved mostly in equatorial climates, where it got very hot later in the day, and napping during the extreme heat optimized work performance.” Hmm, heat does make me sleepy but then again so do cold temps.


The good doctor says don’t overthink your nap time. Find a cool comfortable place you feel safe and just snooze for about 15 to 60 minutes. Set an alarm so you don’t oversleep you don’t want it to interfere with your night sleep. Oh, and here’s the tough part put away your cell phone or any other electronic because the light will keep you from that deep sleep.

I’ve always been a napper since I was a kid. It didn’t matter if I was in school or working, when I got home I napped.  Working early hours for radio, napping just makes even more sense then again, I just love to sleep. ~grace
