Is it possible for swimmers to become dehydrated?

Quck answer

Swimmers can get dehydrated due to the heat and physical exertion involved in swimming. When swimming, the body loses water through sweat and evaporation, leading to dehydration. Symptoms of dehydration in swimmers may include dry mouth, fatigue, dizziness, and decreased performance. To prevent dehydration, swimmers should drink water before, during, and after swimming. It is important to stay hydrated to maintain optimal performance and prevent the risk of heat-related illnesses. Swimmers should also be aware of the signs of dehydration and take necessary steps to rehydrate if needed.


What a refreshing feeling it is to jump into a cool pool on a hot day, isn’t it? As you descend into the water, your entire body is instantly revitalized.

However, if you are a competitive swimmer, the water may not feel as refreshing as when you are simply having fun. When you swim laps or compete against other swimmers, swimming becomes a rigorous form of exercise.

While swimming lap after lap, you may be surprised to find yourself feeling thirsty. Quite peculiar, isn’t it? You are surrounded by water and yet you feel dehydrated on the inside. What could be the reason for this?

What you are experiencing is dehydration. This term simply means that your body has lost a significant amount of water and requires more. But how is it possible for your body to lose water…when you are in water?

Swimming is a demanding exercise, and your body perspires — even in the water — just like it would during running or participating in another sport. However, since you are in the water, you may not realize that you are sweating. As a result, you may not be aware that you are becoming dehydrated.

As your body sweats while you swim, it is necessary to replenish that water. Your muscles communicate with your brain, signaling that you are thirsty and in need of hydration. Just like a runner requires water to perform at their best, swimmers also need to stay hydrated.

It may seem odd to feel thirsty when you are surrounded by water, but it is logical. The body does not absorb water like a sponge. Therefore, even though you are immersed in water, the water necessary for your body to function properly is not being absorbed from the pool. To properly fuel your body, you need to consume fluids!

However, avoid drinking pool, lake, or ocean water! Drinking water from these sources can easily make you ill. Instead, use a water fountain, drink bottled water, or consume sports drinks, just as you would in any other sport.
