Can Swimmers Sweat? Let’s Find Out Now!

There are things we can’t see but can’t say it doesn’t exist. Water sweating is also the same. We can’t see every drop of sweat on our forehead, we can’t see our bareback soaked with sweat when we swim, but the truth is, we definitely perspire when we are active in the water.

Why? Because sweating is a biological function used by the body to cool itself under certain conditions (high ambient temperature or intense body activity). And when it comes to such conditions, whether on land or underwater, the body still sweats. That is the natural mechanism. The only thing is swimmers rarely find themselves sweat because the water surrounds them.

Basically, we sweat to keep our body temperature at a stable level. The human body does not rely on external factors to regulate its temperature, so when the body is hot, it sweats. When swimming, however, you sweat less compared to other intense terrestrial activities. Most swimming pools have a water temperature lower than the average body temperature (37 ° C), so the water helps to cool down your body and reduces your need to sweat. But even if the water keeps you cool, it doesn’t stop the body from inducing that natural response.

So how do you know if you are sweating in the water?

You can’t rely on the feeling of sweating, dry mouth or feeling hot as if you were on land, we have to rely on other methods to know whether we are sweating or not.

The most obvious sign that you are sweating in the water is shortness of breath. It is often an indicator of sweating as it shows you are exercising at high intensity, and your body is sweating to not overheat. So if you find yourself gasping and feeling out of breath, chances are you are sweating.

Also, if you are wearing a swimming cap, you will feel your head warm-up, which is because you are sweating underneath it. And it is important to note that swimmers may continue to sweat after the water training session is over as body temperature is still rising. It takes time for the body to cool down. As a result, swimmers may find themselves perspiring after getting out of the pool and wiping dry.

How much do you actually sweat?

Actually, there are many studies on this issue in the world, but we do not see the need to quote data here. The reason is that the research results will vary depending on the subject of study (professional athlete or normal person), amount of movement in water (high or low), water temperature, air temperature …

We just need to know some important information: women sweat less than men; outdoor swimming pools in hot season are more likely to make swimmers sweat more easily than covered pools or indoor pools; Sweating dehydrates your body, which in turn affects your ability to function in the water and affects swimmer performance.

The most important and remarkable story here is this: the things you do not notice can harm you because you do not anticipate its harm and take measures to stop it in time. Sweating in the water, if not seen and underestimated, your swimming performance will suffer.

So when you sweat, what exactly are you losing?

You’re dehydrated, and with it, you lose electrolytes.

Dehydration occurs when you are using more fluids than you are drinking. This negatively affects your body as it prevents it from performing its normal functions. Signs of dehydration include thirst, irritability, headache, weakness, dizziness, cramps, and heartburn. Excessive dehydration can lead to vomiting, nausea, fainting, and ultimately heat shock.

Dehydration of just 1-2% of total body weight starts to impact performance. When your body doesn’t have enough fluids, it causes your heart rate to spike, which will make your workout feel more difficult.

Electrolytes will also flow out of the sweat you release. Electrolytes help our bodies function well by keeping our pH in balance and regulated. They aid in building new tissue, helping with blood clotting, controlling muscle contractions, and regulating fluid levels.

How can you prevent this dehydration?

To avoid dehydration, always have a water bottle with you before, during, and after a workout. The best athletes know that they need to take regular sips of water throughout their training session. Studies show that you should drink at least half a liter of water during swimming to avoid dehydration.

When exercising, rehydration is your best friend. Water regulates body temperature and lubricates joints, thus allowing the body to function at its peak. It also improves muscle function and blood circulation while regulating blood pressure.

With new sports drinks being made every week, it’s hard to know what you should actually drink during your workout. In most cases, filtered water is the best solution to dehydration. It is completely natural and replenishes what your body is losing.

In fact, swimmers sweat while underwater. They may become more dehydrated than practitioners in other terrestrial disciplines simply because they don’t notice that they’re sweating. Therefore, it is essential and prudent for swimmers of all levels to keep hydrated while swimming to replenish the electrolytes and water lost during exercise.
