However, too much napping or taking a nap at the wrong time can interfere with your night’s slumber. While many people still believe that napping is only for the lazy, there have been a number of famous nappers who recognized its advantages.

Let’s see what the numbers have to say about this sleep habit.

General Napping Facts

1. Over 85% of mammals are polyphasic sleepers.

Polyphasic sleepers sleep several times a day. Unlike most mammals, humans generally sleep only during the night, which makes them monophasic sleepers. However, it’s not certain if this is our natural sleep pattern since there are a number of people who need to nap during the day.

2. There are three types of naps.

A planned nap, as its name suggests, is premeditated. If you know that you’ll have to stay up longer than usual, you can take advantage of this type of afternoon nap. An emergency nap involves napping when you have difficulties keeping your eyes open because you’re extremely tired. Finally, a habitual nap is again pretty self-explanatory—some people like to take a nap every day at the same time.
