Female body feels cold it is stronger than man's body, and often zhensching freezing hands and feet . Of course, in both sexes, this mechanism works the same temperature - cold recognized skin on which the termoretseptornye cells. They are located at a depth of less than a millimeter from the surface of the skin, and it is thanks to their work, and we feel the different temperatures.
Typically, the skin keeps the temperature comfortable for us because of the blood flow through the capillaries - tiny blood vessels. But when thermoreceptors feel cold, they cause the capillaries to close, redirecting blood flow (and heat) to the heart, lungs and other internal organs. The colder outside, the less blood the body spends on heating of the skin, and the greater warming in the vital organs.
But in the female body, this process is started, even with a slight drop in temperature. Because of this, women will begin to feel the cold, they immediately freezing hands and feet And then they needed more time to warm up. The researchers found that when exposed to the cold temperature of the total female body is higher, on average, at 0, 4 degrees Fahrenheit than men, but the temperature of the hands of women by 2, 8 degrees below.
How can this be explained? Blame the female hormone estrogen! That it regulates peripheral blood vessels. And elevated levels of this hormone makes the blood vessels more susceptible to temperature changes. By the way, this explains the change in the temperature of the female body during the cycle. Scientists believe that the female body such recognition cold is needed in order to have time to protect the unborn child from the cold.
In addition, women on average 10% more fat than men. The more fat in the body, the more protection for the internal organs. But the same fat prevents heat to get them to the skin. That's why overweight people skin temperature is lower than in lean. (READ MORE)
