Heat - sweating against heat: annoying, but important for the body

Sweating against heat: annoying, but important for the body

If the temperatures rise, the use of deodorant becomes indispensable. Although sweat is uncomfortable for you, it has an important function in the body. And: Up to six liters of sweat a day is still quite normal.

As soon as the summer sun heats up, everyone groans: The sweat runs down their foreheads in rivers, the shirts are stuck to the back and the feet - well, they don't smell fresh after a hot day. Sweating is not always pleasant, but it has an important function: it regulates body temperature. The evaporating moisture cools the skin and dissipates excessive heat, which is not only vital for sports or strenuous work.

Humans have around three million sweat glands - most of them on the forehead, under the armpits, on the hands and feet - and these produce up to six liters of sweat per day. That is a respectable achievement.

However, the glands can also be uncomfortable in action: When stress or excitement, for example during a lecture or intensive flirting, the stress hormones stimulate sweat production, large drops appear on the nose or soak T-shirts under the armpits. Unsightly sweat stains are doubly embarrassing in such situations and stimulate sweat production even more.

Disturbing sweat streams

This type of sweating is bothersome, but completely normal. However, it can become almost unbearable when the body produces much more sweat than is necessary for cooling. This disorder is called hyperhidrosis and it results in annoying sweat brooks every day. “It's rarely really pathological,” says Vadym Volpov, dermatologist and head of the Center for Venous Diseases and Dermatology in Zurich. "But I have noticed that people quickly experience excessive sweating as very stressful, and as soon as they feel uncomfortable, they come to me for treatment."

In fact, dermatologists can now offer good therapeutic options: "The two methods that work more or less in most cases are operations on the one hand, and botox treatments on the other," explains the vein specialist. With the surgical methods, either the sweat glands are removed or the nerves that trigger sweating are blocked.

However, he finds the latter method too risky, and the effects can often not be precisely assessed. "On the other hand, I have had very good experiences with treatments with botulinum toxin A," says Volpov. "This is a completely harmless method, because so small amounts of Botox are used that they do not even get from the skin into the organism and are no longer measurable after hours."

One method that was often used in the past is iontophoresis, which is particularly suitable for hands and feet. These are immersed in a water bath, where a weak direct current is supplied, which increases the irritation threshold of the sweat glands. "This therapy is actually quite effective," says Volpov. "However, it has to be carried out every day for 10 days and then repeated after a 10-day break - the patients usually don't go along with it for long."

Significantly more unpleasant than excessive sweating alone is if the sweat also smells bad. This is usually not the case with fresh sweat, only when the bacteria multiply strongly does the unpleasant smell arise. However, a disorder called bromhidrosis changes the decomposition of sweat, which consists of water, sodium chloride, urea, ammonia and uric acid, in such a way that it smells extremely unpleasant even in the very fresh version. This is very embarrassing for those affected.

Here, dermatologist Volpov simply recommends his patients: "Shave the region off and keep it dry!" If that is not enough, he can also help here with botox. However, he does not find deodorants with aluminum hexosulfate to be recommended, as these clog the sweat glands from the outside and are associated with an increased risk of breast cancer.

Deodorants do the same

If you sweat normally, a normal deodorant and regular showering and changing clothes are sufficient. Anyone who thinks that too much sweat is flowing now can, by the way, dampen it a little with sage tea. "If that doesn't work and someone sweats particularly heavily at night, we recommend that you see a dermatologist," says Vadym Volpov. Then it is necessary to clarify whether this is an (auto) immune disease or possibly cancer.

However, if you simply sweat heavily on hot summer days, you should urgently drink mineral water, tea or a little fruit juice and eat fresh vegetables, according to Volpov's recommendation: this will give your body enough water and minerals. "All in all, sweating is a very healthy protective reaction of the body to overheating, and it helps to eliminate toxins."
