Why does blood circulation make you hot or cold?



  1. 0 Votes

    Body temperature is closely related to blood flow rate.  The relationship is complex, but the blood flow to the skin is determined by temperature.  If temperature increases, the veins dialate in order increase blood flow and therefore cooling.  The opposite occurs when the body is cold:  circulation slackens in order to preserve heat.

    Researchers at the University of Portsmouth in the United Kingdom discovered some interesting findings about how different people feel the cold. Women have the stereotype of feeling cold easier than men, and there is a good reason for it. The fat layer in women’s bodies is distributed more evenly than in men, and women’s bodies are also more efficient at conserving heat than men. But this also means that women’s hands and feet receive less blood flow to them – thus why they feel cold temperatures sooner than men.
