As you get older, taking an afternoon nap could help keep your brain stay sharp.
That's according to a study just published in General Psychiatry.
Researchers analyzed the napping habits of more than 2,000 older adults in China.
People 60 and up who took afternoon naps showed signs of better mental agility compared to those who did not nap.
Nappers scored higher on cognitive tests that looked at things like memory and language.
The study defined an afternoon nap as being after lunch and lasting between five minutes and two hours.
