Rash from sweating

introduction

Excessive heat causes people to start sweating. And with the sweat, there are often many small red pimples, commonly known as so-called heat rashes, heat rashes or sweat pimples.
This is not a single phenomenon, but a medical clinical picture, which in technical terms is called Miliaria referred to as. The blisters are usually very light to milky in color and are noticeable by their uncomfortable itching. They usually heal quite quickly on their own without leaving any traces.

causes

The heat pimples are caused by clogged sweat pores on the skin. How and why exactly the pores clog has not yet been clearly clarified. In any case, the result is the development of a pimple including redness and itching.
Various theories are taken into account when investigating the cause. For example, one theory assumes that some sweat pores are not fully developed shortly after birth and are therefore susceptible to environmental influences. That could be one reason why babies and toddlers in particular tend to develop heat rashes.
But even in adults, increased physical activity, a hot and humid climate and air-impermeable clothing can stimulate sweat production so much that the pores in the skin close up and pimples develop.
Some medications can also artificially stimulate sweat production and create heat rashes, beta blockers and opiates in particular are known for this side effect.
Various creams, ointments and other skin care products can also close the pores with their ingredients and impair sweat production, which promotes pimple formation.
But other factors such as stress, lack of sleep, allergies and food intolerances and immune deficiencies can also manifest themselves in the form of sweat pimples.
