Napping is a common practice in many cultures, with a third of adults in the United States partaking in a midday nap. While napping can be beneficial, improving alertness, mood, and mental performance, there are also potential drawbacks. The urge to nap may indicate inadequate or poor-quality sleep at night, and napping can sometimes worsen sleepiness and negatively impact nighttime sleep. Research has linked long naps to various health issues, and excessive napping may indicate a sleep disorder. However, short naps of 20–30 minutes in the early afternoon can boost alertness and enhance memory and cognitive abilities without interfering with nighttime sleep. Thus, napping can be beneficial, but it is important to assess sleep habits and discuss persistent daytime sleepiness with a doctor if adequate nighttime sleep is obtained.

What You'll Learn
Napping can improve alertness, mood, and mental performance
Napping has been shown to improve alertness, mood, and mental performance. A nap can be particularly beneficial for individuals who are sleep-deprived or need to be alert at irregular times, such as shift workers.
The ideal nap length for adults is typically considered to be about 20 minutes, with 30 minutes being the maximum recommended duration. Napping for longer than 30 minutes can cause the sleeper to enter deep sleep, and waking up during this stage of sleep can result in grogginess and worsened sleepiness. Napping for 90 minutes allows the body to cycle through the stages of sleep and avoid disrupting deep sleep, which can be beneficial in some cases. However, napping for too long or too late in the day can negatively impact nighttime sleep, leaving you wide awake and interfering with your bedtime routine.
To optimize your nap, aim for a duration of 20 to 30 minutes in the early afternoon, preferably between 1 p.m. and 3 p.m. when humans naturally experience a dip in alertness. Napping during this time can help boost energy levels, increase alertness, and improve mood. If you're well-rested, you may benefit from a slightly later nap, while those who are sleep-deprived may prefer an earlier nap.
Additionally, combining a nap with moderate exercise, such as a walk or stretching in the evening, can further enhance the benefits and improve nighttime sleep. Napping can be a great way to recharge your energy, improve your mood, and enhance your mental performance, especially when timed and executed correctly.

Napping may negatively impact nighttime sleep
In some instances, napping sets up a vicious cycle. You sleep during the day to make up for lost sleep at night, but then you have a harder time falling asleep at night because you slept during the day. Limiting naps is one strategy to improve overall nighttime sleep. If you are getting adequate sleep at night and still feel the need to nap during the day, it is recommended that you discuss this with your doctor to assess your sleep quality and rule out any potential sleep disorders.
The urge to nap can also be influenced by when you last ate. Many people naturally experience a period of decreased energy and alertness in the early afternoon, known as the "post-lunch dip" or "afternoon slump". Napping during this time can boost energy levels, increase alertness, improve mood, enhance memory and cognitive ability, and improve physical ability. However, it is important not to nap too late in the day, or you may find yourself wide awake at night, spoiling your bedtime routine. Experts recommend limiting your nap to at least 8 hours before bedtime to avoid nighttime sleep problems.
The length of a nap can also influence whether it negatively impacts nighttime sleep. Longer naps, such as those lasting more than 30 minutes, can cause the sleeper to enter deep sleep. Waking up during deep sleep can cause grogginess and even worsen sleepiness. Napping for more than 60 minutes a day has been associated with an increased risk of developing type 2 diabetes. On the other hand, a short 20-minute nap allows the napper to get a bit of light sleep to boost alertness without entering into deep sleep.

Napping can be healthy for adults who need to catch up on sleep
Firstly, it's crucial to assess why you may be feeling sleepy during the day. If you're not getting enough sleep at night, aim to improve your nighttime sleep habits. If you're already getting adequate sleep and still feel tired during the day, consult a doctor to discuss your sleep quality and rule out any potential sleep disorders.
If you're aiming to catch up on sleep, the best time to nap is in the afternoon, typically between 1 pm and 3 pm. This is when humans naturally experience a dip in alertness, making it easier to fall asleep. Napping too late in the day can disrupt your nighttime sleep, so aim for at least eight hours before bedtime.
The ideal nap duration for adults is generally considered to be around 20 minutes, with 30 minutes being the maximum recommended length. Shorter naps allow you to get some light sleep without entering deep sleep, making it easier to wake up feeling refreshed. Longer naps can cause grogginess, especially if you wake up during deep sleep.
Napping can offer various benefits, such as improved alertness, enhanced mood, and increased energy levels. It can also improve memory, cognitive ability, and physical performance. Additionally, napping can be beneficial for shift workers who struggle to maintain a traditional sleep schedule and need to be alert at irregular times.
However, it's important to be mindful of potential negative impacts. Excessive napping or napping for longer than 60 minutes has been associated with an increased risk of developing health conditions such as diabetes, heart disease, and depression. Napping can also negatively affect nighttime sleep, creating a vicious cycle where you struggle to fall asleep at night due to daytime napping.

Napping may be a sign of a sleep disorder
While napping can be beneficial in certain situations, it may also be indicative of an underlying sleep disorder.
Napping is a common practice in many cultures, with afternoon catnaps being a regular part of daily life for up to a third of adults in the United States, according to the National Sleep Foundation. Short daytime naps can offer benefits such as helping individuals catch up on lost sleep, improving memory, increasing alertness, and enhancing overall well-being. However, it is important to consider why one may feel the need to nap regularly during the day.
Daytime sleepiness could be a sign of inadequate sleep at night, which is associated with an increased risk of developing chronic conditions such as diabetes, heart disease, and depression. It could also be a result of low-quality sleep, indicating a potential sleep disorder. Sleep disorders like hypersomnia and narcolepsy are characterized by excessive daytime sleepiness and the urge to nap frequently. If you find yourself consistently tired during the day despite getting sufficient nighttime sleep, it is recommended to consult a doctor to rule out any underlying sleep disorders or health conditions.
Additionally, napping can sometimes create a vicious cycle. Taking naps during the day to compensate for poor nighttime sleep can further disrupt your sleep at night, making it harder to fall asleep. This disruption in sleep patterns can negatively impact overall sleep quality and contribute to the development of sleep disorders.
Therefore, while napping can provide temporary relief and have certain benefits, it is important to assess the underlying reasons for excessive daytime sleepiness. If napping becomes a regular necessity, it may be a sign of a sleep disorder or inadequate nighttime sleep, and addressing these issues should be a priority.

Napping for 20-30 minutes is optimal
Napping for 20–30 minutes is optimal for a quick energy boost. Napping for longer than 30 minutes can cause the sleeper to enter deep sleep, and waking up during this stage can cause grogginess and worsen sleepiness. Shorter naps allow the body to get some light sleep without entering deep sleep.
Napping for 20–30 minutes can improve alertness, mood, and mental performance. It can also improve physical ability and enhance memory and cognitive ability. A study found that people who napped for 45–60 minutes had lower blood pressure after experiencing mental stress.
Napping can be particularly beneficial for shift workers who struggle to get enough sleep and need to be alert at irregular times. It can also be healthy for adults who need to catch up on sleep or work odd hours. In many cultures, napping in the afternoon is a regular part of daily life. In the United States, as many as a third of adults regularly partake in a midday catnap.
However, it is important to assess why you may be sleepy enough to fall asleep during the day, especially if you nap regularly. If you are getting at least seven or more hours of sleep at night and are still tired during the day, discuss this with your doctor.
