Daytime Naps: Do They Count Towards Our Sleep Needs?

Napping during the day can be beneficial, but does it count as sleep? While a nap can be refreshing and restorative, it is not a replacement for a full night's sleep. Napping can help relieve fatigue, but it cannot reverse the negative effects of chronic sleep loss. Sleep plays a critical role in overall health, with almost every system in the body relying on sleep to function well. While a nap may give you an energy boost, it won't provide the same restorative power as a full night's rest.

Napping can reduce stress, increase alertness, lower blood pressure and improve productivity and performance

Napping can be a great way to reduce stress, increase alertness, lower blood pressure, and improve productivity and performance.

Reducing Stress

A brief nap during a stressful event can help to improve negative emotions and reduce stress. A study by the University of Texas found that participants who took a 40-minute nap during an acute stressor exhibited lower negative affect after the break than the group that stayed awake.

Increasing Alertness and Productivity

Napping has been shown to improve logical reasoning, reaction time, long-term memory, and working memory. A study by the University of Michigan found that napping participants exhibited higher levels of focus and alertness. Additionally, a 90-minute nap can allow your body to cycle through the stages of sleep, providing substantial benefits and avoiding the grogginess that can come from waking up during deep sleep.

Lowering Blood Pressure

Research has also shown that midday napping can lead to a noticeable drop in blood pressure. A study presented at the American College of Cardiology's Annual Scientific Session found that people who took a midday nap experienced an average 5 mm Hg drop in blood pressure, with a 3 mm Hg decrease in 24-hour average systolic blood pressure for every hour of napping.

Improving Performance

Napping can also improve physical performance. A study by the University of California, Riverside, found that athletes who took a 30-minute nap showed improved physical ability, including faster sprint times and increased accuracy.

To get the most benefits from napping, it's important to nap at the right time and for the right duration. Napping in the early afternoon, between 1 p.m. and 3 p.m., is optimal as this is when most people experience a natural energy dip. Keeping naps under 30 minutes can help avoid sleep inertia, and setting an alarm can ensure you don't sleep too long.

A nap is not a replacement for a full night's sleep

While a nap can be beneficial to reduce daytime fatigue and improve alertness, memory, learning ability and mood, it is not a replacement for a full night's sleep.

Sleep plays a critical role in your overall health. Almost every system in your body needs sleep to function well, from your heart to your immune system. Getting adequate, quality sleep each night helps clear waste from your brain, keeping your mind sharp during the day. A short nap during the day can relieve sleepiness, but it cannot reverse the negative effects of chronic sleep loss.

There are four stages of sleep: stage 1, stage 2, stage 3, and rapid eye movement (REM) sleep. The first three stages are often called non-rapid eye movement (NREM) sleep. Each stage has a unique pattern of brain activity. Dreaming typically occurs during REM sleep, while stage 3 is responsible for restorative deep sleep.

In adults, a nap typically includes all the stages of sleep but in different proportions to regular nightly sleep. While a nap can be a useful stopgap for people who struggle to get enough sleep at night, it does not provide the same restorative power as a full night's rest.

If you are getting a lot of sleep at night and are still feeling excessively tired in the day, discuss this with your doctor. Frequent, unexpected napping during the day may be a sign of a sleep disorder.

The best time to nap is in the early afternoon, between 1 p.m. and 3 p.m

Napping for 10 to 30 minutes in the early afternoon, between 1 p.m. and 3 p.m., is the best way to go for most people. This is because 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 has been found to boost energy levels, increase alertness, improve mood, enhance memory and cognitive ability, and improve physical ability.

Research shows that afternoon naps, when timed correctly, do not negatively impact nighttime sleep. In multiple studies, people who took afternoon naps obtained as much or more sleep in a 24-hour period than those who didn’t nap. However, if you nap too late in the afternoon, or for too long, you may experience difficulties falling and staying asleep during the night. This is because daytime napping reduces your body's need for sleep.

To avoid disrupting your sleep schedule, most experts recommend avoiding naps after 3 p.m. In general, it is recommended to limit your nap to at least eight hours before bedtime to avoid nighttime sleep problems.

For most people, the ideal nap lasts 30 minutes. Shorter naps allow the body to get some light sleep without entering deep sleep. If you wake up during deep sleep, you may find yourself even groggier than you were before the nap.

The ideal nap length is between 10 and 30 minutes

Napping for 10 to 30 minutes is ideal for a quick energy boost without leaving you feeling groggy. This is because shorter naps allow the body to get some light sleep without entering deep sleep. If you wake up during deep sleep, you may find yourself feeling groggy.

The time of day you choose to nap is also important. Napping in the early to mid-afternoon, when most people experience a natural decline in energy and alertness, is optimal. Napping during this time has been found to boost energy levels, increase alertness, improve mood, enhance memory and cognitive ability, and improve physical ability.

If you want to get the benefits of an afternoon nap without experiencing drowsiness when you wake up, try these tips:

• Set an alarm to ensure a short nap.
• Nap in a dark, quiet room, and consider using an eye mask and earplugs.
• Take a "coffee nap" by having coffee just before a short nap, so that the effects kick in when you wake up.
• Nap earlier rather than later. Aim for the early afternoon, rather than the late afternoon, to avoid negatively impacting your nighttime sleep.

Napping too late in the day can negatively impact your sleep quality and duration

Napping is a common practice in many cultures, with as many as one-third of adults in the United States regularly taking a midday nap. While a brief nap can be refreshing and restorative, napping too late in the day can negatively impact your sleep quality and duration.

The key to successful napping is timing. For most people, the ideal nap lasts around 30 minutes and takes place in the early afternoon, between 1 pm and 3 pm. This is when most people experience a natural decline in energy and alertness, often referred to 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, if you nap too late in the afternoon or for too long, you may find it difficult to fall asleep at night. This is because daytime napping reduces your sleep drive, or your body's need for sleep. To avoid disruptions to your sleep schedule, experts recommend avoiding naps after 3 pm and limiting your nap to at least eight hours before bedtime.

If you frequently feel the need to nap during the day, it may be a sign that you are not getting enough sleep at night. Assess your sleep habits and make sure you are getting the recommended seven to eight hours of sleep. If you are already getting an adequate amount of sleep and still feel tired during the day, consider discussing this with your doctor.
