Why Do We Have Hair?

Hair by much_ado_about_nothing

Like most mammals, people have hair over most of their bodies. We aren’t covered with fur all over our bodies like animals are, and scientists think that people today have less hair than primitive humans did. Because of the way that creatures change over time, humans born today have less hair than they did thousands of years ago. But scientists don’t really know why this is — having less hair probably didn’t make it easier for ancient humans to survive.

It’s possible that people decided long ago that humans with certain kinds of hair were just more beautiful, and so those kinds of humans had more babies that looked like them.

Although you have hair on most of your body, some of it is too fine to see. Two places where you don’t have any hair are the palms of your hands and the soles of your feet.

Do you notice that adult men usually have more hair on their bodies than women? Adult men grow hair on their faces and on their upper bodies, while women do not. It’s possible to remove hair from your body by shaving it off.

Children don’t have much hair on their bodies (except for the hair on your head, of course). But as you grow older, your body will gradually change and you’ll grow more hair on different parts of your body. By the time you finish high school, your body hair will look more like what you see on an adult’s body.

    Dear Sir,

    You said men grow hair on their upper bodies, but I’ve read many times men grow more Termial hair all over their bodies than women – and that includes the legs. Would you agree with this? Why mention only the upper body when men usually have hairier lags too? Please reply?

    You invite people to ask questions, yet you don’t reply! Would you agree that men, in general, are hairier all over than women? Not just on the upper body. Please reply?

    he didn’t invite you to ask questions, it’s just a comment place.
    doesn’t say anything about asking questions.

    and he didn’t say that men grow more hair on their legs than woman because that doesn’t apply to every man and woman,
    and it also doesn’t really mean anything.
    he said men grow hair on their upper half of their body,
    like their chest and back. and woman don’t,
    that’s not the same thing as saying men grow more hair than woman on their legs.
    la la la la.

    The article doesn’t tell us why we have hair! Only that we don’t have as much hair and women have less than men!

    Reasons I’ve heard:-
    Warmth to stop losing to much heat from our heads
    Sunblock to stop getting sunburnt
    Friction reduction under arms and between legs
    Smell enhancement to attract mates b/c there is more surface area for bacteria to grow!
    Barrier to stop dust getting in our eyes and noses, and sweat getting in our eyes

    Women actually do grow hair on their face and chest. We grow mustaches and a few hairs on our chin. Some women(not me) have sideburns, and some have more than a few chin hairs. I am a woman of 19 years with a few chin hairs that I just pluck with a tweezer. We have hair on our chins, but very fine. Then we can have a couple to a few thicker strands that then would need tweezing. We also grow hairs on our chest, just not as much as men or in the same location. Since this is a kids blog I wont get to specific and will leave it at that. Good day!
