Many years ago, there was a very famous online post called < < Children with cold hands and feet were angels with folded wings in their last lives > >.
Although it is an emotional chicken soup article, it has hit the hearts of countless people who are troubled by the cold hands and feet. Angels with folded wings are flying everywhere at that time, all caused by the cold hands and feet.
Fortunately, there are no angels in Dr. Clove’s world. Otherwise, friends troubled by palmar hyperhidrosis are not angels with wings soaked in water in their last lives.
Another cold winter is coming. Today we will say that what makes our hands and feet feel extremely cold in winter.
The cause of cold hands and feet
There are two kinds of receptor cells under our skin, [cold receptor cells] and [hot receptor cells], which can sense changes in external temperature and participate in regulating body surface temperature.
Under normal circumstances, our skin is at a very comfortable temperature, so when we shake hands and hug, we all feel good.
However, when cold receptor cells feel cold, they will close capillaries and let blood flow to important organs such as heart and lungs. This self-protection function of the human body is to keep internal organs warm in a cold environment and prevent important organs from being damaged by cold attacks.
Blood flows to internal organs, so the amount of blood flowing to hands and feet is greatly reduced.
As a result, people will feel cold hands and feet, which is why hands and feet are the high incidence of chilblain and frostbite.
Therefore, there is no angel folding his wings, but the blood has gone somewhere else.
Is cold hands and feet a disease?
Cold hands and feet are a self-protection mechanism for the human body when the weather gets cooler.
It is not what, but a normal phenomenon. There is no need to worry about it, let alone treat it.
Some people think that people with weak bodies are more likely to have cold hands and feet.
This view does not hold water, because the symptoms of cold hands and feet are not caused by low basal metabolism or inactivity, but by being too sensitive to changes in external temperature.
Therefore, the degree of body weight and thinness has no direct relationship with what as to whether it will cause cold hands and feet.
Correspondingly, exercise may relieve the symptoms of cold hands and feet, but it cannot fundamentally solve this problem.
Therefore, don’t feel that your hands belong to ice and snow beauties just because you are thin.
Don’t feel that your hands can rub out fireballs in cold winter just because you are fat.
Women are more likely to have cold hands and feet.
Although cold hands and feet are the human body’s self-protection mechanism, this mechanism still has gender differences.
Compared with men, women are more sensitive to changes in temperature, which leads to women’s hands and feet being more likely to cool in cold conditions.
A study published in the famous medical journal Lancet shows that the body surface temperature of women is 2.8 degrees Fahrenheit lower than that of men, but the body nuclear temperature of women is 0.4 degrees Fahrenheit higher than that of men, and the blood pressure of women is low, so women’s hands and feet are generally colder than that of men.
Therefore, if the cold hand is really because I was an angel with broken wings in my previous life, then the angel must be a girl.
A few cases require special attention
Although cold hands and feet are normal changes in most cases, there are also some special circumstances that require special attention:
- Thyroid decay can lead to low metabolism and may lead to cold hands and feet. Iron deficiency, vitamin B12 deficiency, diabetes, lupus erythematosus, scleroderma and other symptoms of cold hands and feet.
In addition, if the color of fingers or toes turns white first and then blue with itchy feeling when hands and feet are cold, it is necessary to consider whether you suffer from Raynaud’s disease.
Therefore, if you often feel cold hands and feet, it is still recommended to go to the hospital and let the doctor check it out to rule out the above possibility.
How to relieve cold hands and feet?
If the cause of the disease is excluded, there is still much we can do in the face of the cold hands and feet caused by the temperature drop in our daily life in what.
For example, drinking more water, doing more exercise, wearing gloves and thicker socks when going out are all possible.
Although these practices cannot fundamentally solve the problem of cold hands and feet, they can bring us some warmth when it is cold.
For the couples who have left the single dog group, a loving hug in winter can drive away all the cold hands and feet.
After all, the sky can be cold, but the heart cannot be cold.
