why women feel cold than men?

Question

I need physiological explanation

Answer 1

Hormones... just hormones. Female sex hormones tend to lower your basal metabolic rate (BMR). BMR determines the rate at which you burn calories and produce heat. With a low BMR (as with excess female sex hormones) means less calories being burnt and more weight gain as fat. Thyroid hormones also play a vital role. Testosterone which is the male sex hormone, raises BMR. That is why men are bit more physically active than women, because they have more testosterone. Both sexes have both hormones but not in equal amounts. Of course there are aberrants.

Answer 2

Women have a higher ratio of surface to volume than men and thus shed heat faster. The reasoning here is that heat generation is determined by volume (radius cubed), while heat dissipation is determined by skin surface area (radius squared). The smaller your size, the lower your heat generation/heat dissipation ratio, and the colder you are. Probably part of the answer--see below.

Men have more heat-generating muscle mass. Muscles are well supplied with blood vessels. The more muscle, the more blood flow and the more warmth.

Women have a higher vasoconstriction threshold temperature. Vasoconstriction is the process by which, as the external temperature falls, blood flow to the skin is restricted in order to divert blood to internal organs, thus maintaining core temperature. The theory: as ambient temp falls, women shut off blood flow to the skin sooner in order to provide more warmth to their unborn babies, so they feel colder. Interesting idea but as yet unproven--though women do seem to have lower skin temperature when exposed to cold.

Women get colder during menstruation. Supposedly this is due to anemia, hormonal changes, etc. However, most studies haven't shown much difference between menstruating and nonmenstruating women in terms of heat response. As you say, female aversion to cold doesn't seem to be confined to a particular time of the month.

Answer 3

Most women seem to have cold hands, I don't know why. I've never known a girl with a cold but though...

Answer 4

Actually, we have more body fat anmd should be warmer. The real difference is in our clothing. We tend to wear lighter garments, have bare legs, go without socks, have lower necklines, and avoid the padded look.
