Is It Normal to Take a Nap After a Workout?

Physical activity is known for boosting energy. That’s because exercise increases your heart rate and blood flow, making you feel awake. It’s one of the many benefits of working out.

However, it’s also possible to get tired after exercise. This is especially common after high-intensity workouts. Physical activity, after all, requires a lot of energy and stamina.

If you feel tired after a workout, you may want to take a nap. In this article, we’ll discuss the pros and cons post-exercise napping, along with tips for doing it right.

Is this normal?

In general, feeling sleepy after exercise isn’t a cause for concern. It’s normal to feel tired after physically exerting yourself.

This is more likely after intense workouts. For example, you can expect your energy levels to dip after a long run or high-intensity interval training.

On the other hand, a lighter workout like a leisurely walk probably won’t make you tired.

Everyone is different, though. Your energy after exercise depends on many factors, including:

  • your fitness level
  • your diet
  • your level of hydration
  • type of exercise
  • duration, intensity, and frequency of exercise
  • underlying medical conditions
  • how much sleep you got the night before

In some cases, feeling sleepy after exercise might be a sign that you’ve pushed yourself too hard.

Why does it occur?

Post-workout sleepiness is caused by the body’s natural response to physical activity.

When you exercise, your muscles repeatedly contract. They use adenosine triphosphate (ATP) to produce these contractions. ATP is a molecule that provides energy for your cells.

Your ATP levels decrease as you continue working out. This reduces your muscles’ ability to function, resulting in muscle fatigue. It’s known as peripheral fatigue.

Your central nervous system (CNS) also plays a role. During exercise, your CNS repetitively fires signals to activate your muscles. The firing, however, will become less charged the longer you work out.

Additionally, exercise increases various neurotransmitters, including dopamine and serotonin. These changes reduce your CNS’ capacity to activate your muscles, leading to central fatigue. As a result, you may feel tired and want to take a nap.HEALTHLINE CHALLENGEAdd mood-boosting food to your diet with our 12-day challenge

Pros and cons

If you’re thinking of taking a post-workout nap, consider the potential pros and cons.

Pros of taking a nap after exercise

The advantages of napping after a workout include:

  • Muscle recovery. Taking a nap after exercise can support muscle recovery. When you sleep, your pituitary gland releases growth hormone. Your muscles need this hormone to repair and build tissue. This is essential for muscle growth, athletic performance, and reaping the benefits of physical activity.
  • Improved sleep debt. Sleep deprivation hinders muscle recovery. It also slows down cognitive function and weakens the immune system, contributing to poor athletic performance. By taking a nap, you can lessen the effects of sleep deprivation by getting more rest.
  • Reduced physical fatigue. Feeling sleepy after exercise is a sign of muscle fatigue. However, as napping encourages muscle recovery, it decreases fatigue. This can make it easier to handle other obligations during the rest of the day.
  • Increased mental alertness. Similarly, taking a nap after exercise can give you a boost of mental energy. If you woke up early to work out, a nap can help you feel less tired.

Cons of taking a nap after exercise

There also some drawbacks to napping after a workout. They include.

  • Poor nap quality. Exercise increases your endorphins and body temperature. These exercise-induced changes can keep your brain and body awake. That’s why some people avoid working out just before bed. Therefore, even if you want to nap, it might be difficult to get quality rest. It might take time to determine if post-workout naps are right for you.
  • Increased grogginess. If you take a long nap, you might enter the deeper stages of sleep. You’ll feel groggy and disoriented when you wake up. This feeling, known as sleep inertia, can last for up to 30 minutes.
  • Disrupted nighttime sleeping. Although napping can decrease sleep debt, it can negatively affect nighttime sleep. You might have trouble falling asleep later at night. Plus, if you have a sleep disorder, napping may worsen your symptoms. Talk to your doctor if you feel the urge to regularly taking naps.

How long should you nap?

Limit your nap to 20 minutes. Avoid napping for 30 to 60 minutes. Otherwise, you may enter deep sleep and wake up with sleep inertia.

Set an alarm for 25 to 30 minutes. This will give you some time to wind down before a 20-minute nap.

If you feel tired after an evening workout, it might be worth going to bed early instead. Just be sure to hydrate and eat a recovery meal first.

Other tips

To get the most out of your post-workout nap, keep these tips in mind:

  • Choose the right time. It’s a good idea to avoid napping later in the day. Try to nap between 1:00 p.m. and 3:00 p.m., when your energy naturally starts to drop. If you nap too late in the day, you might be unable to sleep at night.
  • Stretch. If you haven’t already, stretch your muscles before napping. This will help reduce muscle fatigue and stiffness when you wake up.
  • Rehydrate first. Similarly, it’s important to drink water after working out. Be sure to rehydrate before taking a nap. After you wake up, keep drinking water to hydrate your body.
  • Keep the bedroom cool. Generally, it’s more comfortable to sleep in a cooler room. Set your room’s temperature between 60 to 67°F.
  • Reduce noise. When the rest of the world is awake, it can be difficult to take a peaceful nap. A fan, air conditioner, or white noise machine can help mask outside noise. You can also use ear plugs.
  • Darken the room. Try wearing a sleep mask or closing the blinds. This will reduce your exposure to bright light, making it easier to get quality rest. If you plan to make naps a part of your daily routine, consider investing in blackout curtains.
  • Prioritize nighttime sleep. Naps aren’t a substitute for nighttime sleep. Make it a priority to get enough sleep that night, even if you napped during the day
