of a monkey around 25 million hair follicles only on his arms while there is (you can count if you don’t believe); 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

in almost every part of our body. different functions of bristles available. 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, our the densest hair follicles are in the hair in our head area. is found. 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.

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; also the hairs on our noses act as a kind of air conditioner. sees too. 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

As for the hair in the genital area; especially in women the task of protecting the vaginal area from dust and some microbes in the hairs. The task of the hairs in the anus region is not different from this situation. Again, the reason why there are hairs 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

Arm

On our arms, legs, back and body The main reason for all other hair to exist is to balance our body temperature.Truck. 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?
