NEW YORK (PIX11) — One day after losing an hour of sleep to daylight saving time, Monday marks National Napping Day.

“If you don’t get a good night’s sleep, you will need a nap, or at least feel like you need a nap. And that’s where some of the health issues come,” said Pristas. “It’s not the nap itself that’s harmful; it’s the fact that you might not be getting a good night’s sleep.”
