why do we have hair in your bum

First, let's get one thing straight: Everyone has butt hair once puberty hits. It's 100 percent normal and doesn't make you a freak, we promise. But you might be wondering. what's the point of it? Eyelashes, as you might know, serve the useful purpose of keeping bugs, dust, and other particles out of your eyes; armpit hair prevents your arms from chafing against your sides. But when it comes to butt hair, you might be stumped. Hank Green addressed the topic on SciShow and we're totally fascinated. Bodies evolve over the course of millions of years. We haven't lost our butt hair yet simply because there's no pressing reason for us to do so. Cool, right? The hair traps your own unique scent, which can make you more attractive to mates (you know, way deep in our cavemen brains).


Butt hair prevents chafing between your butt cheeks. So, there you have it в butt hair actually is weirdly useful. Who knew that butt cheek chafing was even a thing? That said, if you want to remove that hair, that's normal, too. в because that's the last place in the universe you want to nick yourself.

and! Grooming our can be comparable to landscaping. We tweeze our eyebrows, trim our beards, and shave our legs to strip awayВ thousands of unwanted hairs. In the process, we come across an unsightly view в butt hair. While weвre aware it exists around our anus, we wonder, "does it serve a purpose? " In Sci Show's, "Why Do We Have Butt Hair? "В host Hank Green explains no one actually knows why we have butt hair, but (no pun intended) it may simply exist because there's "no significant evolutionary pressure against it. " In other words, it does not get in the way of humans procreating.


It may just be a side effect of unintelligent design. Other theories suggest facilitates scent communication. Throughout human evolution, communication through scent has played a pungent role. This is why we have body hair in the same areas where we produce odors. The hair is there to hold onto sebaceous, or oily, secretions that have their own smell and are consumed by bacteria that produces even more smells. Since we all have different smell compounds, and our own microbiomes, each of us smells differently.


It is presumed our early human ancestors used their to help them with everything from broadcasting territorial rights to attracting mates. Butt hair may simply be another way our ancestors enhanced their smell profiles. Lastly, friction may explain the evolutionary purpose of butt hair. Skin rubbing on skin causes friction, which can lead to irritation, rashes, and even infection. Hairs may act as a bit of a protective layer, and those sebaceous secretions hair helps spread work to reduce the pain of chafing. Butt hair could act like a natural anti-chafing cream. It's important to remember there hasn't been much research done to verify these theories, and "not every bit of our physiology needs an evolutionary purpose. "
