Real Reason Why You Russian Woman's Hands are Colder Than Yours |
Scientists have found the real reason why women's hands are colder than men's. It turns out that women and children need to keep their hands in pockets more often because they have less muscle mass.
Many noticed that women have colder hands than men. So scientists from the University of Cambridge conducted a study that explained the reasons for this. It turns out that girsl and children in cold weather need to keep their hands in pockets more often because they have less muscle mass. It is from this index that the possibility of generation of heat, necessary for heating the entire body, depends. This conclusion was made after a group of volunteers dropped their hands into the icy water for three minutes. After that, scientists watched how quickly people were able to warm their chilled hands.
Those who had a large muscle mass warmed their hands faster, which was confirmed by the photographs from a special thermal chamber that fixes the spread of heat throughout the body. This was very surprising to the experts since it was always assumed that in the matter of warming the body, the main benefit is not muscle, but subcutaneous fat. Meanwhile, a full understanding of how the structure of the body affects the process of its heating is of great importance. For example, to produce clothes that will warm women and children.
"We always believed that fat is the main factor in the thermoregulation of the body, but now it turned out that the main role in this matter is played by muscles," the study authors say. - The human body is simply an amazing dynamic system that uses muscles to generate heat and maintain the temperature of the entire body, including the hands. In different countries of the world, indigenous people adapted to live in conditions of extreme cold. For example, they quickly enough restrict blood flow to the hands to make sure that the temperature inside the body remains high. Blood to their limbs comes in waves, and thus provides protection from frostbite. " |
