What You'll Learn
Napping improves alertness, mood, and mental performance
Napping for a short period during the day can have several benefits. It can improve alertness, boost energy levels, and help overcome the afternoon slump. Napping can also improve mood and increase positivity and frustration tolerance. A quick nap can also be beneficial if you didn't get a good night's sleep the previous night.
Research has shown that a midday nap can significantly lower blood pressure. A study presented at the 2019 American College of Cardiology's Annual Scientific Session found that midday sleep lowered blood pressure by 5 mm Hg on average, comparable to taking low-dose blood pressure medication. Another study of older Chinese people found that naps lasting 30 to 90 minutes improved word recall, a sign of good memory.
However, napping too long or too late in the day can negatively impact nighttime sleep. Longer naps can cause grogginess and fatigue, especially if they extend beyond 30 minutes, as the sleeper may enter deep sleep. Napping for more than 60 minutes has been associated with an increased risk of developing type 2 diabetes and other negative health impacts, such as high blood pressure and non-alcoholic fatty liver disease.
To optimise the benefits of napping, it is recommended to limit naps to 10 to 20 minutes, ensuring they end at least eight hours before bedtime. Napping during the early afternoon, between 1 p.m. and 3 p.m., is considered optimal, as it aligns with the natural dip in energy and alertness that many people experience at this time. Additionally, drinking coffee before a short nap can further enhance alertness.

Naps longer than 30 minutes can cause sluggishness
Napping has been proven to have health benefits, including boosting brain health and lowering blood pressure. However, it is important to keep naps short, between 10 and 20 minutes, to avoid feeling sluggish and groggy. Longer naps can cause sluggishness because they allow the body to enter a deeper stage of sleep, which can make it harder to wake up and increase feelings of fatigue.
When you nap for 10 to 20 minutes, you enter the first and sometimes second stages of sleep, which is enough to refresh you and provide the benefits of napping, such as increased alertness and improved mood. However, if you nap for longer than 30 minutes, you may enter the third stage of sleep, which is a deeper and more restorative stage of sleep. Waking up during this stage can be difficult, and you may feel more tired than before your nap.
The ideal nap length is generally considered to be about 20 minutes, and no longer than 30 minutes, to boost alertness without entering deep sleep. Naps longer than 30 minutes can also have negative health impacts. One study found that napping for more than 90 minutes was associated with high blood pressure in middle-aged and older women, and another study linked longer naps to a higher frequency of non-alcoholic fatty liver disease. Additionally, longer naps may interfere with cognition, especially in older adults, affecting their ability to think and form memories.
While a 30- to 90-minute nap can provide benefits for older adults, anything longer than 90 minutes may create problems with cognition. Researchers have found that people who napped for 30 to 90 minutes had better word recall and figure drawing abilities, indicating good memory and cognition. However, longer naps may be a sign of poor-quality nighttime sleep, which can lead to cognitive problems.
In summary, napping for longer than 30 minutes can cause sluggishness by allowing the body to enter a deeper stage of sleep, making it harder to wake up and increasing feelings of fatigue. To avoid sluggishness, keep naps short and aim for the ideal nap length of about 20 minutes to boost alertness and refresh yourself without entering deep sleep.

Coffee naps can boost energy levels
Napping can be beneficial in many ways. A quick nap can enhance your performance, increase alertness, improve your mood, and even lower blood pressure. However, the key to reaping these benefits is to keep the nap short, ideally between 10 and 20 minutes. Longer naps can lead to feelings of grogginess and fatigue, and may even be associated with a higher risk of cardiovascular disease and other health issues.
While a short nap can be refreshing, combining it with coffee may seem counterintuitive. However, the "coffee nap" has gained popularity as a way to boost energy levels throughout the day. The concept is simple: drink a cup of coffee and then take a short nap, typically for 15 to 20 minutes. This timing is crucial because it takes about that long for the caffeine to kick in. By the time you wake up, you should feel more energized due to the combined effects of the coffee and the nap.
The science behind the coffee nap suggests that it works by manipulating adenosine, a chemical that promotes sleep. When you feel tired, adenosine levels are high, and they begin to drop once you fall asleep. Caffeine competes with adenosine for receptors in the brain. So, when you nap, your brain clears out some adenosine, and when you wake up and the caffeine kicks in, there is less adenosine for it to compete with, resulting in increased alertness.
Multiple studies have confirmed the effectiveness of coffee naps, finding them to be more beneficial than just drinking coffee or taking a nap alone. For example, a 1997 study on drivers showed that combining coffee with a nap could eliminate the mid-afternoon peak in driving accidents. Additionally, coffee naps have been found to improve physical and mental performance and enhance mood.
However, it's important to be mindful of the type and amount of coffee consumed. Most studies use the equivalent of about two cups of coffee or 100-200 mg of caffeine. Excessive caffeine intake can cause restlessness, anxiety, and other issues, and it's recommended to stop drinking coffee at least six hours before bedtime to avoid sleep disturbances.

Napping too late in the day can disrupt sleep
Napping is a short period of sleep that usually occurs during the day. While napping can be beneficial, there are some considerations to keep in mind, such as the timing and duration of the nap. Napping too late in the day can disrupt nighttime sleep, and the ideal time for a nap is thought to be in the early afternoon, between 1 p.m. and 3 p.m. This is because many people experience a natural dip in energy and alertness during this time, known as the "post-lunch dip" or "afternoon slump". Napping during this time can help boost energy levels and improve alertness.
The recommended time for a nap is generally considered to be at least eight hours before bedtime to avoid disrupting nighttime sleep. For most people, napping for 30 minutes or less will have the most beneficial effects. Longer naps, such as those exceeding 30 minutes, can lead to feelings of grogginess and fatigue upon waking, as the body may enter a deeper stage of sleep that is harder to wake up from.
Additionally, napping too late in the day can be a sign of insufficient nighttime sleep. If you find yourself frequently napping or needing longer naps, it may be an indication that you are not getting enough quality sleep at night. This can lead to a vicious cycle where daytime napping further disrupts nighttime sleep, exacerbating the problem.
The ideal nap duration is typically considered to be around 20 to 30 minutes, allowing for a brief period of light sleep without entering deep sleep. Napping for longer than 60 minutes has been associated with negative health outcomes, including an increased risk of cardiovascular disease, type 2 diabetes, and all-cause mortality.
While napping can provide benefits such as improved alertness and mood, it is important to be mindful of the timing and duration of naps to avoid potential disruptions to nighttime sleep. If you are experiencing frequent sleep difficulties, it is advisable to consult a healthcare professional to assess your sleep quality and rule out any underlying sleep disorders.

Napping can improve brain health
Napping can have a positive impact on brain health, but the length of the nap is important. While a 30- to 90-minute nap can have brain benefits, anything longer than 90 minutes may cause problems with cognition, including the ability to think and form memories.
Research has shown that people who nap for 30 to 90 minutes have better word recall and figure drawing, both of which are signs of good cognition and memory. This was demonstrated in a study of 2,974 people in China aged 65 and older, where those who napped for 30 to 90 minutes displayed better cognitive performance than those who did not nap or who napped for longer than 90 minutes.
Brief naps of 5 to 15 minutes can also provide almost immediate benefits to mental performance, and these benefits can last for up to 3 hours after the nap. Longer naps of more than 30 minutes can cause sleep inertia and grogginess immediately after waking up, but they can lead to improved cognitive performance for a longer period afterward.
Frequent napping may also have long-term benefits for brain health. Studies have found that people who nap frequently tend to have larger total brain volume, which could compensate for inadequate sleep and preserve brain health as we age. This suggests that habitual napping may help to maintain brain health and potentially limit cognitive decline.
In summary, napping can be beneficial for brain health, particularly when the nap duration is kept to between 30 and 90 minutes for older adults and 5 to 15 minutes for brief naps. Napping for too long or too late in the day can interfere with nighttime sleep quality and cognition, so finding the right balance is crucial.
