In evolutionary theories, it is often told that humans have hair because they are descended from apes. While we respect this theory as in every other theory, we can say that in recent years science has made satisfactory explanations about hairs, although not completely.

While a monkey only has around 25 million hair follicles on its arms (you can count it if you don’t believe it); In the whole body of a person, this number is around 5 million on average. Besides, we think it would be useful to mention an anecdote by the way. Although we sometimes use “feather” instead of the word hair in daily life, feathers are found only in birds; Let us remind you once again that what we see in other living things is hair.

Reasons for the existence of hair on our body

Hair in almost every part of our body has different functions. For this reason, the reasons for the existence of each hair area are different. That is why we will consider each part of our body separately. In this distribution of tasks, hairs have many functions in evolutionary theories, but today we will talk about the tasks of hairs independently of evolutionary theories.

The main task of dizzying full hair

As you can imagine, the most dense hair follicles in our body are found in the hair on our head. While an average hair grows 0.3 mm per day; Again, we can say that an average hair bristle is 0.03 mm thick. The general task of the hairs in our hair, namely our hair, is to protect our head from the cold air in winter; In summer, it is to protect from direct sun.

One of the densest hair follicles is in our nose.

Maybe it’s hard to believe, but after our head, the most dense hair follicle in our body is in our nose. Thanks to the hairs on our nose, the entry of dangerous things such as foreign bodies, dust and insects into our nose is prevented; In addition, the hairs on our noses act as a kind of air conditioner. Especially when breathing through our nose in winter; It is a danger for our health that the cold air we breathe goes directly to the lungs, but the hairs on our noses warm this air and send it to our lungs, thus protecting us.

About our hair around the eyes

There are two different hair groups around the eyes: eyelashes and eyebrows. Eyelashes protect our eyes from dust and foreign objects. In addition, eyelashes allow us to close our eyes by showing a sudden reflex against objects coming towards our eyes (you can try with your finger).

Our eyebrows, on the other hand, prevent liquids such as rain and sweat from reaching our eyes directly. In addition, our eyebrows have a great contribution to us in terms of communication. Many gestures and facial expressions; expressed with the help of eyebrows.

Ear hairs burned with alcohol at the hairdresser

The task of our ear hairs is partly similar to the duties of our nose hairs. Our ears, which have a sensitive structure, reach a certain temperature thanks to the ear hairs; dust particles that can enter our ears are also prevented by the ear hairs.

Underarm and genital hair

Many people define armpit and genital hair as unwanted hair. Although the hair in this area is expressed as unwanted among the society, we should not forget that these hairs also have a duty.

The main task of our armpit hair is to protect our sensitive lungs from cold by keeping the heat. In addition, it is the hairs that protect our underarm area, which is susceptible to irritation, from irritation.

As for the hair in the genital area; Especially in women, the duty of protecting the vaginal area from dust and some microbes is in the hairs. The task of the hairs in the anus region is not different from this situation. Again, the reason for the presence of hair in this area in both men and women is to keep the genital area at a certain temperature level and to prevent irritation by reducing friction.

Our hair on arms, legs and other areas

The main reason for the existence of all other hairs on our arms, legs, back and body is to balance our body temperature. Especially when our body temperature drops, the hairs absorb the heat from the outside and serve to warm our body. Again, our hair acts as a protection for our body from direct sunlight in summer.

This is how scientists explain the reasons for the existence of hairs so far. However, new information may be added to this information in the future. So what do you guys think about the hair on our body?
