What Makes Body Hair Grow?


Body hair can reduce the risk of skin cancer. As stated by the scientists at the University of Southern Cleveland (Australia), body hair reduces the impact of solar radiation on the human skin, which lessens the risk of skin cancer.

For ten years, the experts have been analyzing data on more than 20 thousand people living in different parts of the country. With the help of special equipment, the experts checked the degree of radiation that passed through skin. They found that hair made the level of absorbing radiation much lower, reflecting about 30-40% of the total amount of radiation and preventing its contact with the skin.

In addition to explaining one of the functions of hair, the findings of the research sheds light on the evolutionary principle, according to which people living in hot sunny countries often have thicker hair than “northerners”.

Meanwhile, fashion dictates the rules, which are often opposed to nature: this is why people have come up with shaving, waxing, sugaring and other methods of hair removal. Therefore the people, who resort to these methods, should always use sunscreen products to protect themselves.
