Body hair sure is a nuisance, but does it actually serve a purpose? Why do people grow hair in unwanted places? Why does it grow back so quickly when you pluck or shave it? Why do people need laser hair removal in NYC to keep it from growing back thicker and faster? What's the point of these sensitive, unsightly hairs all over the body? Creepy-Crawlies Human hair might seem useless to modern people, but it actually serves a purpose. Researchers have found that human hair can help detect parasites on the body. Hairs trigger sensations, even very fine ones. If you have ever experienced a sudden and strong itching sensation anywhere on your body, it is likely that a parasite, dirt particles, or other small stimuli have triggered your body hair. Of course, this does not mean that those without hair are vulnerable to swarms of parasites. Your skin is still sensitive to sudden intruders like bedbugs or mosquitoes. Also, keep in mind that bloodsucking parasites tend to target areas with very little hair, like the neck, ankle, and wrist. Hair Evolution Humans are relatively hairless compared with other apes—the group of animals with which humans share the most biological similarities—but humans still have hair on nearly every surface of the body. The fact that human hairs tend to be finer and shorter than hair on apes seems to be an evolutionary progression or biological change over time, according to researchers. Areas without hair (typically the palms of the hands and bottoms of the feet) remain smooth to allow for grip, balance, and steadiness. Hair in these areas would make basic activities far more difficult. It seems, then, that body hair is becoming less useful over time. While some women may be attracted to men with thick body and facial hair—it is a sign of higher testosterone levels—modern women's tastes are changing. Humans today seem to associate a lack of excess body hair with cleanliness and attractiveness. Men, meanwhile, tend to prefer a lack of body hair on women, as this signals low testosterone levels. Men and women who are concerned about these hairs that used to be useful and are now just a nuisance should consider effective and pain-free solutions like laser hair removal in NYC.
