Why do we sweat?
Thanks for asking.
The last week or so has seemed temperatures reach around 20 degrees in the south of England,
and you can expect to see similar temperatures for the next month or so as we head into summer.
Whenever the weather warms up, there's always a temptation to try to mask any odors or stains
that are coming from our sweaty bodies, but it's worth bearing in mind that sweating is actually a crucial bodily function.
Did you know that sweat is a watery solution that contains mostly water, but also some minerals and proteins?
Not everyone sweats the same way.
How we sweat depends on a range of factors like age, genetics and hormonal changes.
For some, sweating can become a major source of discomfort or embarrassment.
Now the scientific term for excessive sweating is hyperhydrosis,
and according to the International Hyperhydrosis Society, it affects as many as 5% of people in the world.
Just what is the purpose of sweat then?
You may have heard certain myths about sweating which simply aren't true, and I'm here to debunk them.
For example, some people incorrectly believe it helps us lose weight,
when in fact it just dehydrates us. Another popular belief is that sweating detoxifies the body,
whereas in reality most of our toxins are expelled through urine, not sweat.
In fact, sweating mostly helps regulate our body temperature,
keeping it around 37 degrees Celsius where it needs to be.
That's right, it's a form of automatic temperature control,
and it relies on 3 million tiny sweat glands, which are found under the skin,
especially in our palms and the soles of our feet.
You've probably noticed these glands kicking into gear when it's hot,
during exercise, or when you're in a stressful situation.
Many people understandably make a connection between sweat and the bad smells and stains on our
clothes that can appear when it's hot, but in reality sweat is odorless and colourless.
It's actually the bacteria on our skin that produce those odors,
and the stains are caused by a mix of bacteria,
sebum, and chemicals from detergents or shower gels, rather than the sweat itself.
Still, some people experience a malfunction of their sweat glands,
which is called bromehydrosis, or more commonly, body odor.
Is there a link between sweating and hair removal?
No, there isn't, and that's because sweating and hair follicles aren't connected.
Whether you shave frequently or not at all simply want to affect your sweat production.
If you're looking to manage sweating better, you should really look closer at your diet,
rather than getting hung up on hair removal.
For example, drinks with caffeine stimulate the nervous system and sweat glands,
increasing sweat production.
The same goes for alcohol and spicy foods, which raise body temperature and trigger sweat glands.
It's also important that you stay hydrated and eat foods that are easy to digest.
Avoid processed foods, refine grains, red meat, and processed meats as they can slow digestion and
raise body temperature. There you have it! Now you know why we sweat.
