Napping is a short period of sleep, typically lasting from a few minutes to a couple of hours. It is often taken during the day to help restore energy and improve alertness. Naps can be beneficial for people of all ages, providing a quick way to recharge without the need for a full night's sleep. There are different types of naps, such as power naps, which last about 20 minutes, and long naps, which can last up to 90 minutes. Research suggests that napping can enhance cognitive function, mood, and overall well-being, making it a valuable practice for many individuals.
