remember things better and make fewer mistakes. Also, you can learn things more easily after taking
a nap. A 20-minute
nap can reduce information overload. It can also reduce stress, Finally, a nap may increase your self-
confidence and make you more alert. It may even cheer you up.

of the day, about eight hours after you wake up, Otherwise, you may disturb your sleep-wake pattern.
