The tattooing process involves permanently depositing ink under the skin at a similar depth as the sweat glands, Alma College’s Maurie Luetkemeier and two students posed the question: Does possessing a tattoo interfere with the basic functions of the sweat gland?
They conducted a study involving ten students who had tattoos on one side of their upper body but not the other and a group of ten non-tattooed people.
They chemically stimulated both sets of skins, inked and non-inked, and found that the tattooed skin produced about half as much sweat as the non-tattooed skin and the tattooed skin was significantly saltier.
Luetkemier was worried about the findings and said that: “future research may address the ultimate question whether or not heavily tattooed individuals are at risk of heat-related injuries.”
Why is he worried? Well, sweating helps your body maintain a proper temperature and keeps you from overheating and if this is tampered with, it could signal serious risks for your healthExplore more on these topics:
