If you use a graph to describe the temperature difference between men and women in winter, it must be like this...
Is it you?

"Cold hands and feet" seems to have become a "synonym" for girls in winter. Legend has it that girls with cold hands and feet "no one hurts", "in the last life was an angel with broken wings", "it is not good to have children after the palace is cold"... It was as if cold hands and feet had become a measure of whether a girl was healthy.

As a guardian of women's health who implements love and justice, today Zhimei will come to uncover the truth about why the "angels" have cold hands and feet! But don't be fooled by the "legend" again.
First of all, the conclusion: big mistake!
The blood vessels in our body are all over the body, supplying nutrients and heat to maintain life and body temperature, while the skin has two major receptor cells, cold and hot, which can participate in regulating the surface temperature with the change of external temperature, creating a relatively comfortable body feeling for us [1].
So when the cold receptor cell feels the cold, it will immediately trigger its visceral protection mechanism, by closing the capillaries, so that more blood flows to the heart, lungs, and keep more important organs warm. Since the hands and feet are the ends of the cycle, it is normal to feel cold.

Therefore, cold hands and feet are not a disease, let alone a palace cold, but the body simply feels cold.
Mainly related to the following reasons:
1. Women have lower thermogenesis ability
Men tend to do manual labor in the evolutionary process, not only skeletal muscles are developed, but also the arterial perfusion flow is relatively larger, so the blood flow is more abundant. Women are the opposite, so the peripheral blood flow is small, the thermogenic capacity is low, the arterial irrigation flow is weaker, the limbs are less blood supply than boys, and the hands and feet are more likely to be cold.
2. Women's hands and feet dissipate heat faster
Due to the action of estrogen, women's subcutaneous fat is generally thicker than men's, but the fat of hands and feet is less than that of men, so that warmth is poor.

3, women are generally more sensitive
Women's strong sensory system not only knows her boyfriend's every move, but also judges the temperature better! This is because estrogen is more capable of regulating body temperature, and women have just higher levels of estrogen [2]. Therefore, women are more sensitive to changes in temperature. The same temperature change, perhaps men have not felt it, women have already felt the cold.
4, women dress is not warmer
In order to be beautiful girls generally wear thin clothes in winter, in order to look thin, they also prefer tight clothing such as leggings, which can easily lead to poor blood circulation at the end of the body, and it is easier to have cold hands and feet.

Although most people's cold hands and feet are a normal reaction of the body, there are also some special cases to be careful about: such as low metabolism caused by the decay of thyroid function, iron and vitamin B12 deficiency, diabetes, lupus erythematosus, scleroderma, etc. will also have symptoms of cold hands and feet.
In summary, as long as you are healthy, cold hands and feet are not a big problem, but it is inevitable that it is a little uncomfortable to be cool, so Zhimei has summarized a warm strategy for everyone, please "angels" Save Oh:
1. Exercise more
When you feel cold, you only need to summon up the courage, get rid of laziness and exercise, and it won't be long before you can warm up. Long-term adherence to exercise can increase the body's ability to store calories, improve terminal blood circulation, and develop cold resistance. If you think that outdoor sports in winter are too cold, you can jump warm-up exercises and jump rope at home, and at the same time warm up, you can effectively avoid hoarding meat in winter, and girls who love beauty are moving me!
2. Drink more hot water
Don't think that "drinking more hot water" is a useless nonsense, after all, eating cold food and drinks in winter is physically cooling the body. In addition to taking warm boiled water as a daily drink, it is also necessary to eat more warm food to make the body warm up quickly.
3. Soak your feet before going to bed
Girls with boyfriends can put cold little feet on their boyfriend's stomach to warm up... Singles without a boyfriend can insist on soaking their feet, which is an effective way to relieve the coldness of their hands and feet, and help improve their body's ability to withstand cold. Before going to bed, use water to soak your feet at about 40 ° C, soak until your body is slightly sweaty and put on warm socks, you can sleep warmly.
4, dress to keep warm
Wearing warmth is an important measure to protect against cold. Take care of the head, neck, back, feet, navel, knee joints and other parts, and the whole person will be much warmer. Don't insist on "beautiful frozen people" for the sake of good looks, wearing hats, high necks, high-waisted pants, and autumn pants are all good methods.
Finally, Zhimei wished that every little angel's hand would be covered this winter.
