On the human body has many holes?

If you only pay attention to your eyes, nose, ears, genitals, you can say it right away: men have 8, women have 9. However, think a little more, maybe the body also has a lot of sweat glands, Hair follicle . If so, it must be said that no one could answer.

There are follicles that grow into thick, thick hair with follicles growing but the fluff is very thin on the skin. Hair and hair distribution also depends on gender and age. Hair color is also significant: brown-haired people have higher density of hair follicles than red-haired people.

The first to study this was anthropologist Adolf Schulz. He tried to rely on hair to distinguish people and other primates.

He found people and primates on average had the same number of hair follicles / hairs. That number is about 300 per cm ² . On the chest, the density of hair follicles is the smallest, only one capsule over 1cm ² . The average hair follicle density is 5,000,000 holes on the human body (that is only based on hair follicles).

In addition to hair follicles, we must also consider sweat glands. In the last century, Karl Kraus first examined the skin under a microscope and concluded that, for example, the density of sweat glands is 600 pieces per 1 cm ² . A recent study estimates the total number of sweat glands in humans is about 3 million.

Interestingly, the larger the primate species, the smaller the density of hair on the body . Since there is no effective perspiration system, monkeys must adapt to the limits of temperature. People are an exception to the general rule. On average, we have five times more sweat glands than monkeys, but our hair is much thinner than them.
