Why Does Going To The Pool Make You Tired?

When the weather is hot, there’s nothing better than swimming in a pool to cool off. But what’s the deal with how tired you feel after a swim? Is it just dehydration? Or is something else going on? In this post, we’re going to take a closer look at why swimming makes you so tired. Stay tuned!

Why does going to the pool make you tired?

Ever been to the pool to relax, have fun and swim a bit, then got home and felt exhausted afterwards? There are a few reasons why swimming, and even just visiting the pool without doing lengths, makes us tired:

Why does going to the pool make you tired?

1. Exercise

Swimming is more tiring than it initially appears because of the way water affects your body. Water is much denser than air, meaning that every movement you make in the pool requires more effort than it would if you were doing the same thing on land. Your muscles have to work harder to push through the water, which can quickly lead to fatigue. 

When you dive into the pool, your body is suddenly met with a force that it isn’t used to – water resistance. Unlike running on the ground where there is little resistance, swimming works your muscles much harder since they have to push against the water in order to move forward. Although your body weight is supported by the water, you have to work hard to keep yourself afloat in the swimming pool.

Swimming is a full body workout which uses all the major muscle groups in your body. A good swim workout is hard on your entire body and therefore uses up a lot of energy when compared with other forms of exercise.

In addition, swimming also requires you to use your lungs more efficiently in order to get enough oxygen while your mouth and nose are submerged. As a result, swimming is an excellent form of aerobic exercise that uses all the major muscle groups in your body. However, because it is such an intense workout, it’s no wonder that you might feel tired afterwards!

2. Water temperature and body temperature

In addition, being in water also causes your heart rate to increase. This is because being in cold water forces your body to work harder to maintain its internal temperature. As your heart rate rises, so does your blood pressure and respiration rate. All of this adds up to make swimming a surprisingly strenuous activity.

Cold water can cause your body to expend more energy to warm up. Even if the pool is only cool, you will still need to work harder than usual to maintain your body’s core temperature. Second, after completing a workout, your body needs to continue working to warm up. This means that your heart rate and breathing will stay elevated, making you even more exhausted.

It’s not just cold water that can make you feel tired. If the water is too warm this can also lead to fatigue.

When you swim in water that is too warm, you will sweat more during your exercise as your body tries to cool itself down. This can lead to you becoming dehydrated quicker and you will feel tired more easily. This is why you feel tired after taking a shower.

So next time you hit the pool, don’t be surprised if you find yourself feeling a little tired afterward. It’s all part of the workout!

3. Dehydration

When you go for a swim, your body is working hard. Not only are you resistance training against the water, but you’re also expending a lot of energy to keep yourself afloat. On top of that, you’re likely breathing harder than normal as well, which means your body is using up oxygen at an accelerated rate. All of this physical activity takes a toll on your energy levels, and it’s further compounded by dehydration.

When you perspire, you lose not only water but also electrolytes like sodium and potassium, which are essential for proper hydration. As a result, it’s not surprising that you feel exhausted after a dip in the pool.

The best way to combat this fatigue is to drink plenty of fluids before and after swimming, and to make sure that you’re replenishing your electrolytes as well. By taking these simple steps, you can help ensure that your next trip to the pool is a refreshing one.

Dehydration is also one of the main reasons you get tired in a hot tub.

4. Relaxation

Because swimming is an aerobic exercise, it helps improve your cardiovascular health and can even help reduce stress and anxiety. 

One of the reasons why swimming can be so relaxing is because it gives your body a chance to focus on something other than stressful thoughts. When you’re swimming, all of your attention is focused on the simple act of keeping yourself afloat and moving through the water. This can help clear your mind and give you a break from whatever is causing you stress. 

The feeling of being weightless in the water can also be very relaxing. Water has a natural buoyancy that supports our bodies and takes some of the pressure off our joints and muscles. This can help alleviate pain, especially for people with conditions like arthritis. 

When we are relaxed our bodies release endorphins, which are hormones that have mood-boosting effects. As a result, swimming can not only help reduce stress but can also improve your overall mood and sense of well-being.

5. Chlorine

Chlorine is added to pools in order to kill off bacteria and other microorganisms that can cause disease. Unfortunately, chlorine also has a detrimental effect on our bodies, particularly in large quantities like those found in swimming pools. When we swim in chlorinated water, the chlorine reacts with the proteins in our hair and skin, causing irritation and dryness. This process is called oxidation and it sucks all of the moisture out of our bodies, leaving us feeling tired and depleted. 

In addition to causing dehydration, chlorination also strips our bodies of natural oils that protect us from harmful UV rays. This means that we are more susceptible to sunburn when we’ve been swimming in a chlorinated pool. So not only are we left feeling fatigued, but we’re also more vulnerable to skin damage. 

Fortunately, there are ways to minimize the effects of chlorine. For example, you can shower after swimming in order to rinse off any residual chlorine on your body. You can also purchase a bathing suit made from UV-protective material which will help reduce your risk of sunburn. And be sure to drink plenty of water both before and after swimming— this will help replenish any fluids you may have lost while swimming. 

6. Sun at outdoor pools

Going to the pool can make you tired for a few different reasons. One is sun exposure. Being in the sun can make people feel tired and sleepy. This is because the sun’s rays can cause chemical changes in the body which can contribute to fatigue. For example, sunlight triggers the release of melanin, a compound that helps to protect the skin from UV damage. Melanin can also absorb light, and this process generates heat which can lead to feelings of fatigue.

Additionally, swimming in the sun can also lead to dehydration, which can then make you more tired after a workout. So, if you’re looking to avoid feeling exhausted after a dip in the pool, it’s best to swim indoors or during cooler hours when there is less direct sunlight.

Why am I more tired after swimming than during swimming?

Have you ever gone for a swim and then felt more tired afterwards than you did during the swim itself? In fact, there are a few reasons why this phenomenon occurs.

Muscle repair

After a swim, your body will have to repair itself and use all of its muscles.

One of the main reasons why you’ll feel more tired after swimming is because your body has to do a lot of work to repair itself. All of the muscles in your body will have been used during the swim, and so they’ll need time to recover afterwards. This process takes energy and can leave you feeling pretty exhausted.


Another reason why you might be feeling more tired after swimming is because of the re-warming process that your body goes through. When you get out of the pool, your body temperature will start to drop pretty quickly. In order to compensate for this, your body will start working hard to generate heat and warm itself back up again. This process can be quite taxing on your energy levels and leave you feeling quite exhausted afterwards. 

Post-workout fatigue.

Finally, it’s important to remember that post-workout fatigue is a very real thing. Even if you don’t feel particularly exhausted after your swim, it’s entirely possible that you’ll start feeling more tired as the day goes on. This is because your body is still in recovery mode and trying to repair all of the damage from the swim. So if you’re feeling more tired later on in the day, don’t be too surprised! 

Do you sleep better after swimming?

If you’re looking for a way to relieve stress and get a good night’s sleep, look no further than your local pool! Swimming is a great way to relax your body and mind, and it can also help you get the rest you need. Here’s how:

Releases endorphins.

Endorphins are hormones that help improve mood and reduce stress levels. When you swim, your body releases these feel-good hormones, which can help you feel more relaxed both physically and mentally. This can lead to improved sleep quality at night.

Exercise is tiring.

It’s no secret that exercise can be tiring. But this fatigue can actually be beneficial when it comes to sleep. After a swim, your body will be tired out from all the activity, which can make it easier to fall asleep at bedtime.

Body temperature drops after getting out of the water.

Swimming in cool water can lower your body temperature, which is ideal for falling asleep. When you get out of the cold pool, your body will begin to cool down further, as water evaporates from your body, making it easier to drift off to sleep later on.

How do I stop being tired after swimming?

Find yourself getting overly tired after a swim session? Here are some ways to avoid that post swimming fatigue:

1. Eat well

We all know how it feels to be tired after swimming. You might feel like you could just collapse on the pool deck and take a nap. But there are a few things you can do to help yourself recover and feel more energetic after your swim.

First, make sure you’re eating the right foods. Swimmers need to eat a balanced diet that includes plenty of complex carbohydrates and protein. Complex carbs are found in whole grain breads, pasta, and rice. They provide sustained energy throughout the day. Protein is essential for repairing and rebuilding muscles. Good sources of protein include chicken, fish, tofu, and beans.

Your post-workout meals should include plenty of protein to help your muscles repair and give your body some much needed energy.

2. Warm shower

After your swim, take a warm shower instead of a cold one. The warm water will help to relax your muscles and relieve any tension or stiffness. It will also help to raise your body temperature, which can help you feel more energetic. This is particularly important after getting out of a cold pool, as your body will be losing extra heat as the water evaporates from your body.

3. Wear the right kit

Wearing ill-fitted swimming attire can actually make you feel more tired as it pulls against your body. A swim cap that’s too tight can give you a headache. Goggles that leak can also cause fatigue as your eyes have to work harder to stay open underwater. Wearing the right kit will help you feel more comfortable in the water and make your swim more enjoyable.

4. Stay hydrated

Dehydration can cause fatigue, so it’s important to make sure you’re drinking plenty of fluids both before and after your swim. Drink water or a sports drink before and after your swim to replenish any fluid you’ve lost through sweating. Drinking during your swim is also important, especially if you’re swimming for more than an hour.

5. Improve your swimming technique

If you find yourself getting tired quickly when swimming, it might be time to work on your technique. Poor technique can cause you to use more energy than necessary, leading to fatigue. A swimming coach can help you identify any areas where you need to improve and give you the tools you need to swim more efficiently.

6. Take a walk

Taking a walk outdoors will help you to clear your head and reenergize your body. The fresh air and moderate exercise will help to improve your circulation and boost your energy levels.

Swimming is a great exercise for your whole body, but it can be tiring. By following these tips, you can help yourself recover and feel more energetic after your swim.
