Winter is coming, and many people are suffering from chilblain.
These red and swollen gadgets on the skin do not itch, hurt and are afraid of scratching. Not only affect life, but also affect beauty. All kinds of earthwork and foreign parties to prevent and treat chilblain have tried their best, but they are useless.
How can we really prevent chilblain? How should chilblain be treated to heal? Today, Dr. Clove will talk about this topic.
First of all, let’s start with the origin of chilblain.
How did chilblain come from?
Chilblain is a local inflammatory damage to the skin caused by cold and damp.
Because a long period of cold causes arterioles to contract, after a long period of time, blood vessels are paralyzed and expanded, veins are congested, local blood circulation is poor, capillary permeability is enhanced, plasma exudes and runs into tissue gaps, thus causing the disease.
There are many factors leading to chilblain, such as:
- Wet (humid environment, sweaty hands and feet, etc.); Local poor blood circulation (shoes and socks are too tight, there are basic diseases such as diabetic foot, or lack of exercise); Fatigue; Systemic factors such as malnutrition (e.g. Anemia, etc.).
Chilblain is not caused by extreme cold.
Many people think that chilblain is caused by cold and low temperature. In fact, the cold below 0 ℃ often causes severe acute frostbite instead of chilblain.
In our country, most chilblain is caused by long-term exposure to cold environment above 0 ℃ and below 10 ℃.
So every time Doctor Clove hears the sentence: “You are snowy in the sun in the south, and I am spring-like all the year round in the cold nights in the north”.
The pictures that emerge in my head are all:
A people in the three northeastern provinces who have seen horses blowing in the wind, ice eating in the snow, and arms bare in the freezing temperature of minus 30 ℃ are colder than their houses, colder than quilts, and colder than their hearts in Jiangsu, Zhejiang and Shanghai, where postage does not cover warm areas, with chilblain in one hand and snot shaking…
How to prevent chilblain?
In fact, there are only three really effective measures to prevent chilblain:
1. Keep warm:
In the place where you live, you should try your best to keep the room temperature not lower than 10 ℃. Take care of yourself, friends from the south.
If you go out, pay attention to keeping the weak parts warm. If you can’t, wear more socks and gloves.
Tight pants/socks will make your lower limbs tight and cause chilblain due to poor circulation. It is a difficult choice whether to have a wonderful curve or swollen hands and feet like pig’s trotters.
2. Prevent sharp changes in cold and hot temperatures:
Rapid temperature change is one of the causes of chilblain. In cold environment, peripheral blood vessels are contracting. Sudden contact with overheated things will make capillaries suddenly relax and expand, and local blood circulation will stagnate immediately, which will soon form chilblain.
The correct approach is to return to the warm environment and then massage the limbs that are hardest hit by the cold.
For example, if your hands are exposed, you can clap your hands and rub your fingers and palms repeatedly to help local blood circulation. After the numbness of your limbs disappears, you can apply it briefly with a warm water towel.
3. Moderate physical exercise:
It can promote the whole body blood circulation and is the ultimate means to prevent chilblain. Running and other aerobic exercises can achieve the goal.
Pregnant women, elderly people with physical weakness and people with cardiac insufficiency do not have to force themselves to do intensive exercise, but can be replaced by brisk walking or walking.
Eating mutton does not prevent chilblain.
Many people think that mutton and other foods may prevent chilblain. After eating, they will feel [warm] and feel that chilblain will not come back.
In fact, the reason why the body feels warm after eating mutton is mainly because high-protein mutton provides sufficient calories and has no special effect on improving local microcirculation.
Therefore, don’t satisfy your appetite under the banner of preventing chilblain.
There is no particularly effective way to treat chilblain.
Although chilblain is deeply hated, I wish I could get rid of it in minutes and then quickly.
However, Dr. Clove can only tell everyone the sad fact that chilblain does not have a particularly effective treatment.
Although some vasodilators, such as nicotinic acid (vitamin PP), can be taken orally, it can also be wet applied with a warm towel or applied and massaged with vegetable oils such as olive oil.
However, all these methods are only to relieve the symptoms and make us feel less itchy and sore for a short time. However, there is no method to make it heal early. Chilblain will not heal itself until the warm spring comes.
Therefore, for those friends who are favored by chilblain, they should start to prepare for anti-freezing and moisture-proof exercise. After all:
