Why people with tattoos sweat less

Let's figure out what the process of tattooing is. In short: the needles penetrate under the skin and inject a certain amount of paint into the dermis - a layer of skin consisting of collagen fibers, nerves, blood vessels and glands, including eccrine ones. It is they who are responsible for the production of sweat, which is then excreted by the pores on the surface of the skin and evaporates, cooling it.

Recently, researchers from Michigan found that tattoos using even the most modern technology leave for life not only a beautiful pattern, but also sweating problems.

During the study, scientists tested the skin of ten volunteers aged 21 years who had large tattoos on one of their arms or legs.

The participants in the experiment were equipped with special sensors that stimulated sweating, and also collected sweat and analyzed its composition.
