Why Do Humans Still Have Armpit and Pubic Hair?

Humans still have armpit and pubic hair because they help keep our bodies warm and clean in a simple, fun way, like having little helpers on your skin.

Imagine you're wearing a cozy sweater on a chilly day. Now imagine tiny, soft hairs growing under your arms, they act like mini sweaters for your body! These armpit hairs help trap heat, keeping you warm when it's cold outside.

Now think about a time you were playing in the mud or running through puddles. You probably felt wet and dirty afterward. Pubic hair works like a little towel, it helps absorb sweat and moisture, so your skin doesn’t feel too soggy all the time. It also gives our body a natural way to clean itself up when we move around.

These hairs are like tiny helpers that work day and night to keep us warm, dry, and comfortable, just like having extra layers on a chilly day or a towel after playing in the puddles!
