A 20-minute nap is a short period of sleep that typically lasts around 20 minutes. This duration is considered ideal for a quick refresh, as it allows the body to enter light sleep without going into deeper sleep stages. This helps avoid grogginess upon waking, making it easier to resume daily activities. Research suggests that a 20-minute nap can enhance alertness, improve mood, and boost cognitive performance. It is often recommended for individuals who experience fatigue or need a quick energy boost during the day. This type of nap can be particularly beneficial for those with busy schedules.
