You certainly know what a mosquito bite looks like and that simply does not correspond to what you spot on your skin on hot days:bumps or blisters everywhere! What are those exactly?
The end of summer is in sight. And although most of us will not immediately be waiting for another heat wave like last month, a bit of sunny late summer is not wrong! You have probably spotted those small, sometimes slightly itchy bumps or blisters on your own skin. While you do not have a sun allergy. What is that then?

In fact, it is a skin rash. And that in turn means:a sudden deviation to describe the skin. It is often accompanied by (mild) itching and redness of the skin. And yes, sun and heat can indeed cause such a thing. Even without immediately speaking of a sun allergy.
Firstly, there are medicines that can give a reaction in combination with a lot of direct sunlight and heat. You have probably heard that people who take antibiotics, for example, should stay out of the sun. This applies to more medication, so it is always smart to read the package leaflet carefully and/or consult your doctor if in doubt.
But the biggest, main and fortunately also most innocent culprit? That's sweat. More specifically:if it is very hot, you also sweat more and the drainage channels of the sweat glands can become somewhat clogged. That in turn causes a visible reaction on your skin, in the form of small red, sometimes itchy bumps and blisters. Actually, those blisters temporarily hold that sweat for you. And as soon as they pop or disappear, that sweat is gone too.
The same effect can occur when exercising at high temperatures. The bumps and blisters are most common on the hands, but they can also appear in other parts of your body. They are often very small, about a millimeter in diameter. A remedy can be to keep your body cool(er). And furthermore, using talcum powder is a nice tip to prevent. In the vast majority of cases, the bumps and blisters disappear on their own. And especially when it gets cooler outside.
