The Weird Reason You Sweat So Much, According to Science

Sweat is complicated. We all deal with it, it's always unpleasant, and nothing is worse than a little glow that turns into melted makeup because of excessive perspiration. However, we all have that one friend who seemingly never sweats as much as we do. (Why is she so blessed?) Well, there are a lot of factors that are in play, but according to an article in New York Magazine, your childhood has a lot to do with your sweat levels.

Dr. Laure Rittié, a researcher in dermatology at the University of Michigan Health System, explains that we're all born with pretty much the same number of sweat glands, they mature during the first two years of life, and not all of them develop into sweat-producing glands. So how does the gland decided whether or not it will become a pesky perspiring one? "People who grew up in warm climates tend to have more active sweat glands than people who grew up in a climate-controlled environment or in cold climates," says Dr. Rittié. "As adults, we keep all our sweat glands, but only a portion of them are able to produce sweat. This percentage varies between individuals."

Who knew your early years and where you grew up had so much to do with something as common as sweat? But with air conditioning being so popular, many of today's adults from a region like the Southwest are probably not as prone to sweat as someone who didn't have access to AC growing up somewhere like Mexico. Either way, it's kind of nice to know that when you embarrassingly hot and your BFF barely breaks a sweat, there's science to blame.
