You’re running around, playing a great game and — what’s this? Your back is all wet and so is your face. Don’t sweat it — it’s only sweat!
Your body works best when its temperature is about 37ºC (98.6ºF). When your body gets hotter than that, your brain doesn’t like it — it wants your body to stay cool and comfortable. So the part of your brain that controls temperature, sends a message to your body, telling it to sweat, so it can cool down.
Then special glands in your skin called sweat glands start making sweat. Sweat is also known as perspiration, and it is made almost completely of water, with tiny amounts of other chemicals, salts and sugar.
The sweat leaves your skin through tiny holes called pores. When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapour). As the sweat evaporates off your skin, you cool down.
Sweat is a great cooling system, but if you’re sweating a lot on a hot day or after playing hard you could be losing too much water through your skin. Then you need to put liquid back in your body by drinking plenty of water so you won’t get dehydrated.
Why Does Sweat Smell?
Sweat isn’t just wet — it can be kind of STINKY, too. But the next time you get a whiff of yourself after running around outside and want to blame your sweat glands, hold on…
Sweat by itself doesn’t smell at all. It’s the bacteria that live on your skin that mix with the sweat and give it a stinky smell. And when you reach puberty, special hormones affect the glands in your armpits — these glands make sweat that can really smell. Body odor happens when sweat and bacteria mix.
What can I do???
Luckily, regular washing with soap and water can usually keep stinky sweat under control. So it is very important that you wash daily! It also helps to wear clean clothes and obviously underwear each day. Wearing deodorant or antiperspirant helps A LOT! You will both smell and feel better. Those feeling embarrassed about asking their parents to buy them deodorant or wearing it, trust me on this, DON’T BE!! It is something natural that happens to everyone. Your parents will understand and support you.
When you start wearing deodorant, choose a mild one. Avoid deodorants that have heavy scents. Also, deodorants that come in a stick are generally easier to use than ones that are a liquid or gel. And if your new deodorant makes your skin red, itchy, or irritated, stop using it and let your parents know.
So don’t worry about a little sweat — it’s totally normal and everybody sweats.
Just remember…DON’T WORRY… .
Hope this post made things a bit clearer for you!
