"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, she was an angel with broken wings", "it is not easy to have children in the future"...It's as if cold hands and feet have become a standard to measure whether a girl is healthy.
As a guardian of women's health that implements love and justice, today Zhimei will uncover the truth about why the "angels" have cold hands and feet!But don't be fooled by "legends" anymore.
Let's start with the conclusion: big mistake!
The blood vessels in our body are all over the body, and nutrition and heat maintain life and body temperatureThere are two major receptor cells, cold and heat, which can change with the outside temperatureInvolved in regulating skin temperature,Create a relatively comfortable body feeling for us [1].
Therefore, when cold receptor cells feel cold, they will immediately trigger their internal organ protection mechanism, by closing the capillaries, allowing more blood to flow to the heart and lungs, keeping more important organs warm. Since the hands and feet are the ends of this 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.
It is mainly related to the following reasons:
Females have a lower capacity to produce heat
Men have evolved to do manual work, with more skeletal muscles and greater arterial perfusion, resulting in more adequate blood flow. On the contrary, women have less peripheral blood flow, lower heat production capacity, weaker arterial perfusion, less blood supply to the limbs than men, and cold hands and feet.
Women's hands and feet dissipate heat faster
Due to the effect of estrogen, women's subcutaneous fat is generally thicker than men's, but the fat in the hands and feet is less than that of men, so the warmth is poor.
Women are generally more sensitive
Women's powerful sensory system not only knows their 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, it may not be felt by the male, but the cold is already felt by the female.
Women are even less warm when they dress
In order to be beautiful, girls generally wear thin clothes in winter, and in order to look thin, they also prefer to wear tight clothes such as **, 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 it is normal for most people to have cold hands and feet, there are some special situations to be careful with: low metabolism due to hypothyroidism, iron and vitamin B12 deficiency, diabetes, lupus erythematosus, scleroderma, etc.
To sum up, 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 always be cold, so Zhimei has summarized a warm strategy for everyone, please Save it for all "angels".
Get moving
When you feel cold, as long as you muster up the courage to get rid of laziness and exercise, it won't be long before you can warm up. Long-term consistent exercise can increase the body's ability to store calories, improve blood circulation at the end, and develop the potential to protect against cold. If you feel that outdoor exercise is too cold in winter, you can jump warm-up exercises and jump rope at home, which can effectively avoid hoarding meat in winter while being warm
Drink plenty of hot water
Don't think that "drink more hot water" is a useless nonsense, after all, in winter, you are still greedy for cold, raw and cold food and drinks, which is to physically cool the body. In addition to taking warm water as a daily drink, you should also eat more warm foods to warm up your body quickly.
Soak your feet before bed
Girls who have boyfriends can put their cold little feet on their boyfriend's stomach to warm ......Single people who don't have a boyfriend can insist on soaking their feet, which is an effective way to relieve cold hands and feet, and help improve the body's ability to withstand the cold. Before going to bed, soak your feet in about 40 water for a while, soak your body until you sweat slightly, and put on warm socks, and you can sleep warmly.
Dress warmly
Warm clothing is an important measure to protect against the cold. Take care of your 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 looking good, wearing hats, high necks, high-waisted pants, and autumn pants are all good ways.
