Nap needs and the benefits of napping can vary among individuals. Knowing the facts about napping can help determine whether to tát take naps, and tips for better naps can enable healthier napping habits.
Naps can deliver a number of benefits. Brief naps can be restorative and reduce fatigue during the day. After a night of insufficient sleep, a nap may counteract daytime drowsiness . Naps can be particularly beneficial for shift workers who struggle to tát get enough sleep and have to tát be alert at irregular times.
A short daytime snooze may also boost workplace performance . A nap can improve cognitive functions such as memory, logical reasoning, and the ability to tát complete complex tasks.
Some studies have found that physical performance can also improve after napping . Athletes may experience improved endurance, reaction times, and cognitive performance if they take a daytime nap.
Napping may provide other health benefits. One observational study found that napping one or two times a week was associated with a lower risk of cardiovascular problems , such as heart attack, stroke, or heart disease. However, more research is needed to tát understand the complex ways that the frequency and duration of naps affect heart health.
Napping may also reduce the impacts of insufficient sleep. For example, a small trial found evidence that naps relieved stress and supported the immune system in people whose sleep was limited the night before.
Additionally, naps may contribute to tát the well-being of specific groups of people. For instance, a study of people diagnosed with intracranial aneurysms found that regularly napping was associated with a lowered risk of a rupture of the aneurysm.
What Are the Drawbacks of Napping?
Although there are a variety of benefits to tát napping, naps may have drawbacks for certain people. For example, for older adults, napping during the day is associated with self-reported sleep problems such as waking up frequently during the night.
Napping may have other negative health impacts. One study in Đài Loan Trung Quốc found that napping for more than thở 90 minutes was associated with high blood pressure in middle-aged and older women. Another study of older Chinese people found that taking naps longer than thở 30 minutes was correlated with a higher frequency of non-alcoholic fatty liver disease .
An analysis of multiple studies found that napping for more than thở 60 minutes a day was associated with an increased risk of developing type 2 diabetes . Another large study of people living in France found napping to tát be more common in people living with anxiety or depression, obesity, high blood pressure, and type 1 and type 2 diabetes.
To date, it is not clear how exactly naps affect health. Much remains unknown about the relationship between naps and nighttime sleep, and how the frequency or length of naps influences well-being for different people.

Whether at night or during the day, sleep unfolds in a series of stages that làm đẹp a sleep cycle.
- Stage 1: Stage 1 is the lightest and briefest stage of sleep, lasting only one to tát seven minutes.
- Stage 2: Stage 2 follows stage 1 and lasts about 10 to tát 25 minutes. During stage 2 sleep, the muscles relax, and body toàn thân functions slow. However, sleep in this stage is still relatively light.
- Stage 3: Stage 3 is a deeper, more restorative stage of sleep, and it can be difficult to tát wake up while in this stage. Stage 3 usually lasts between đôi mươi and 40 minutes.
- Rapid eye movement (REM): During REM sleep, the body’s muscles are temporarily paralyzed, and the eyes move quickly under closed eyelids. Dreaming tends to tát take place during REM sleep.
When sleep periods last several hours, the body toàn thân cycles through these stages several times. During a nap, though, there is not enough time to tát go through multiple sleep cycles.
In fact, during a short nap, a person may not be asleep long enough to tát spend much, if any, time in stage 3 or REM sleep. This can actually make it easier to tát wake up refreshed from a quick nap.
Longer naps, such as those lasting more than thở 30 minutes, can cause the sleeper to tát enter deep sleep, and deep sleep may start even sooner in people who are sleep deprived. Grogginess often results from being woken up during deep sleep.
To get the full benefits from nap time, it is important to tát consider where, when, and how long to tát nap. These and other factors can influence how a person will feel after waking up from a nap.
How Long Should a Nap Be?
In general, the best nap length for adults is about đôi mươi minutes and no longer than thở 30 minutes. Sleeping for đôi mươi minutes allows the napper to tát get a bit of light sleep to tát boost alertness without entering into deep sleep. Waking up from deep sleep can cause grogginess and actually worsen sleepiness.
In some cases, a longer nap of around an hour and a half may also be beneficial. This length of time allows the body toàn thân to tát cycle through the stages of sleep and avoids interrupting deep sleep. This type of longer nap may be especially helpful for emergency workers and shift workers who are trying to tát avoid fatigue.
Napping may be too much if it interferes with sleep at night. Sometimes a nap of 90 minutes or so sánh can be refreshing, but it may be problematic if it happens too late in the day. Dependency on naps, rather than thở consistent nighttime sleep, can contribute to tát fragmented sleep or sleep disorders such as insomnia.
However, naps may not affect everyone in the same way. Some research suggests that napping affects nighttime sleep primarily in older adults rather than thở young and middle-aged adults.
When to tát Take a Nap
Experts typically recommend that adults take naps eight or more hours before bedtime. For most people, that means napping before 3 p.m. Napping too late in the day may contribute to tát nighttime sleep problems.
For some people, naps may feel natural or even necessary after lunchtime. This is sometimes known as the post-lunch dip. While eating lunch may play a role in afternoon sleepiness, the post-lunch dip is linked to tát circadian rhythm. Circadian rhythm is the body’s internal clock that follows a 24-hour cycle. Within this cycle are two peak periods for sleepiness. The greatest peak is during the night, and the second one falls in the early afternoon.
Where to tát Take a Nap
A good sleep environment is cool, quiet, and dark. Having a comfortable nap setting can help prevent unwanted interruptions or awakenings.
For people who work from trang chủ, a bedroom is likely a good place for a short snooze since it is already phối up to tát promote sleep. Adding blackout curtains or a white noise machine to tát block out distractions may help both at night and during daytime naps.
In an office setting, accessories such as earplugs or an eye mask can reduce disruptions during nap time. When possible, naps should be taken in a space where interruptions are unlikely to tát occur. Some offices may even have nap pods or other quiet areas for relaxation or a short period of restorative sleep.
Remember to tát Set an Alarm
Before dozing off during nap time, phối an alarm for the desired nap length, which should generally be around đôi mươi minutes.
When the alarm goes off, tự not hit snooze to tát keep sleeping since this can risk entering deeper sleep. Setting a second alarm to tát go off shortly after the first one may help to tát avoid napping for too long.
Try to tát get up as soon as the alarm sounds and then stretch or walk around to tát shake off any post-nap sleepiness.
Consider Caffeine Naps
People taking a nap to tát get a boost of energy may benefit from drinking caffeine before napping. The brain and body toàn thân feel the impact of caffeine about 30 minutes after it is consumed, so sánh having caffeine right before a short nap may increase alertness after waking up.
