Are naps (Nap time, Power nap ) good for you?

Actually, naps are good for most people, Mednick says. Her research shows a nap—defined as daytime sleeping that lasts between 15 and 90 minutes—can improve brain functions ranging from memory to focus and creativity. “For some people, naps are as restorative as a whole night of sleep,” she adds.

How long should I take a nap?

Limit your nap to 45 minutes or less, if you need to spring into action after dozing. Otherwise, you may drift into slow-wave sleep. Waking from this stage results in sleep inertia, that grogginess and disorientation that can last for half an hour or more. But you might want to take a long nap, at least 90 minutes.
