Perspiration Is Good for Your Health!

As your body’s temperature increases, your sweat glands work harder. These produce sweat that evaporates through the surface of your skin to keep your body’s temperature down. To make this process possible, the water molecules in your body need energy, which they draw from your organism, thus reducing your body’s temperature.

When your body perspires, it loses significant amounts of water. It is therefore important to rehydrate yourself. When you sweat, you also lose substances like salt, potassium, zinc, copper, iron and vitamin C. You must therefore also make up for those losses. Among other things, you can put a little amount of salt in your water or have some energy drinks specially formulated provide athletes with those essential substances.

Note that if you are not accustomed to intense heat or effort, you will inevitably perspire more.

Dehydration and heat stroke: a major health hazard

If you stop perspiring and your skin becomes dry, red and hot while you’re exercising or when it’s really hot outside, you may be suffering a heat stroke. Once dehydrated, your body can no longer let the heat out and this can be a serious threat to your health.

That is why it is of the utmost importance that you get sufficient hydration. Don’t wait until you’re thirsty to drink. If you’re thirsty, you’re already dehydrated. It is best to drink small amounts at frequent intervals. You should drink a couple of mouthfuls every 10 or 15 minutes. You should also listen to your body.

The pool isn’t the best place to cool down

Even if you don’t realize it, you also perspire when you’re in the water. However, sweat cannot evaporate in a wet environment and thus cannot bring your body’s temperature down. Hence you must get proper hydration even when you’re bathing.

Why does one perspire more and their face turn red after an intense effort?

The more one’s muscles work, the more blood gets pumped into them, to the detriment of other parts of the body. During an effort, blood flow concentrates around the muscles that provide the bulk of the work. Once the exercise is over, blood flow toward the skin will increase to allow heat to exit the body. As the smaller blood vessels in one’s face expand as a result, their face turns red.

In the end, remember that when your body is sweating, it’s also breathing!
