Power naps have health benefits, according to sleep researchers.

Doctors are sharing tips on how you can take better naps to improve your brain function, mood, and alertness.

Naps are important for your mental acuity and memory, researchers said.

The quality of that nap is also important.

According to a survey, 90% of respondents said they felt tired or groggy after a nap.

Some tips sleep experts recommend to fight that grogginess include keeping your sleep space cool, dark, and quiet.

Experts also recommend you keep your naps to 20 minutes or less to avoid falling into deeper sleep.
