The mysterious connection between baldness and beard
Let's face it: the vast majority of balding men begin to rapidly grow a beard. Is this a coincidence?
Researchers believe that there is. They suggested that the reason the balding men to grow a beard faster, may consist in an attempt to maintain the necessary temperature balance.
They found that men speed sweat on the head is much higher than in the beard, while women and boys sweat rate in both these areas is approximately the same. 10 years later, they met again measurements of the rate of release of sweat, and found that the correlation between regions persists.
In general, thicker than a man's beard, the more sweating it top. Which, incidentally, is a pretty cool place, at least in comparison with other parts of the body.
According to the researchers:
«hypothesis that male pattern baldness has arisen in the course of evolution as compensation for beard growth, allowing to achieve better heat dissipation, has been verified. For the experiment were selected 100 men are bald, and with the hair on his head as a beard, and without it. During the measurements revealed that mild hyperthermia at the rate of sweat on his bald head was 2-3 times higher than the head, covered with hair. On the other hand, the rate of evaporation was almost the same chin women and beardless young men, while in adults, clean-shaven men, the rate of perspiration on his chin was 40% lower than in the head. These results support the hypothesis that male pattern baldness is a kind of compensation for the growth of a beard ».
