My hands get frostbite every year, even frostbite. Is there any way to make it stop moving?

In the cold winter, many people often have cold hands and feet and get frostbite. According to statistics, there are 200 million people suffering from chilblain in China every year, mainly children, women and the elderly. In the cold season, chilblain is difficult to be cured quickly, and often it will gradually heal after the weather gets warmer, but patients usually have symptoms such as red, swollen and thick fingers and itching in the affected area.

As we all know, hands and feet are the peripheral parts of human blood circulation and the prone parts of chilblain. After late autumn, the temperature plummeted and the blood flow of peripheral blood vessels became slow. When the temperature is lower than 10℃, the subcutaneous arterioles in the above parts contract when cold, and the venous return is not smooth, thus causing frostbite.

There are also some patients who induce chilblain because of cardiovascular dysfunction. The reasons include: weak heart, unable to fully supply blood to the periphery; Insufficient blood volume, low hemoglobin and red blood cells. In addition, if blood vessels are blocked, or a cold, fever, and elevated body temperature affect the central nervous system of the brain and inhibit motor nerves, it will lead to cold hands and feet. Therefore, measures should be taken in advance to prevent frostbite according to its pathogenesis, which often gets twice the result with half the effort.

The key to reduce frostbite is prevention, and the specific methods of warming hands and feet vary from person to person. Here is a brief introduction for you:

First, physical exercise.

In winter, we should carry out physical exercises suitable for our own conditions, such as practicing Qigong, dancing, skipping rope, etc., or use the interval between washing hands, faces and feet every day to gently rub the skin until it is slightly hot, so as to promote blood circulation, eliminate microcirculation obstacles and achieve the purpose of "promoting blood circulation".

Second, temperature difference soaking.

Take a pot of water at 15℃ and a pot of water at 45℃, first soak your hands and feet in low-temperature water for 5 minutes, and then soak them in high-temperature water. This can exercise the contraction and expansion function of blood vessels and reduce the occurrence of frostbite.

Third, drug prevention.

People with chilblain constitution can increase their intake of vitamins A, C and minerals in January before winter, and can take nicotinamide tablets 0. 1g orally, three times a day, and calcium tablets 0.5g, three times a day, so as to improve the cold tolerance of the body. You can also apply pepper tincture (take 20 grams of dried pepper, soak it in 500 ml of 75% alcohol, and use it after 7 days), and rub it 2-3 times a day. You can also take a proper amount of traditional Chinese medicine, such as Panax notoginseng, Carthamus tinctorius, Radix Paeoniae Rubra, Caulis Spatholobi, etc. Decoct with water, scrub locally, or take with Danggui Huoxue Tongmai Decoction.

People who used to have frostbite constitution usually suffer from this chronic disease every winter. After recovery, they will leave scars on their hands and feet, which is very distressing. However, with the warming of the world temperature, the improvement of working environment, the improvement of nutrition intake and the renewal of health care consciousness, the problem of frostbite in winter has been obviously alleviated in general big cities.

Etiological symptoms

Frostbite is a very common skin disease in winter. It is precisely because of the cold weather in winter that the exposed skin is stimulated by freezing. As time goes on, the subcutaneous arterioles spasm and contract. Produce blood stasis, local tissue hypoxia, tissue cell damage.

At first, the lesion was a localized broad bean or purplish red lump or induration with bright red edges and blue center. Symmetry is more common at the ends, especially at the extended side of the back of the hand and fingers, at the edge of the foot and at the extended side of the toes, at the lower limbs, cheeks and auricles. Consciously local pain, itching, even worse after heat, pain after ulceration.

Suffering from wind and cold, chilblain skin appears pale, red and swollen, purple spots, burning pain and itching, numbness, blisters and ulceration. These symptoms can last for 65,438+0-2 months, until the weather gets warmer, and some patients will recur in the same place next winter. Traditional Chinese medicine believes that chilblain is caused by insufficient cold protection of exposed parts, invasion of cold pathogens and poor circulation of qi and blood. In addition, it is also related to factors such as poor physical fitness, not cold tolerance, sedentary, and overwork. Humidity will accelerate the heat dissipation of the body surface, so people with sweaty hands and feet are also prone to frostbite.

Keep your skin moist and take a scientific bath.

There are four taboos in bathing in winter: avoid being too diligent, the water is too hot, the rubbing is too heavy, and the soap is too alkaline. Otherwise, it is easy to destroy the original sebum on the skin surface, making the skin drier and therefore more itchy and chapped. The number of baths should be 1-2 times a week. After bathing, you can rub some licorice oil, antipruritic cream, moisturizing cream and so on. Keep the skin moist and prevent the skin surface from drying off.

Heat preservation and cold protection

In winter, the temperature is low, and exposed parts of the skin are prone to frostbite, such as hands, head and neck. Others, such as feet, are also prone to freezing, so we should pay attention to the cold and warmth of these parts, such as wearing scarves, gloves, earmuffs and cotton shoes to keep warm, rubbing hands and ears at any time, padding feet and exercising in time. Avoid wearing wet clothes, shoes and socks. Meanwhile, dry your hands and face before going out.

Avoid using inferior cosmetics.

Inferior cosmetics are toxic to the skin because of impure texture or heavy lead content. Some cosmetics contain some allergic spices, some people will be allergic after using them, and even increase the pigment. These are easy to cause harm to the skin. In winter, under the condition of less sebum, the damage is greater.

Dress softly.

Wear more clothes when it's cold in winter, and it's easier to feel itchy if you don't pay attention. This is because the body and clothes, clothes and clothes constantly rub to produce static electricity, which irritates the skin. Therefore, in winter, try to choose cotton, silk and other clothes that are not easy to generate static electricity to make underwear, underwear, shirts and so on. At the same time, we should also pay attention to the collocation of clothes. If you wear a polyester shirt, don't wear an acrylic sweater. If you wear synthetic fiber clothes inside, don't wear insulating polyester coat outside to prevent static electricity.

Carry out skin exercise

Strengthen skin exercise and enhance skin adaptability to adapt to the cold environment. You can take a cold bath, an air bath, sunbathing, massage, etc. Still insist on washing your face with cold water and wiping your body with cold water.

Pay attention to diet and health care

When the human body lacks vitamin A, the skin will become dry, scales will appear, and even prickly papules will appear on the skin. Therefore, we should eat more foods rich in vitamin A in winter, such as pork liver, eggs and cod liver oil. You can also often eat sesame (sesame oil), soybeans, peanuts and other foods, which contain unsaturated fatty acids, such as linoleic acid. Without linoleic acid, the skin will become dry and the scales will become thicker. At the same time, some foods will aggravate the condition of people who originally suffered from certain skin diseases. For example, patients with purulent skin should eat less sweets and drink less. Pepper, onion, garlic, wine and strong tea will aggravate the itching symptoms of people with pruritic neurological disorders. Kelp and pasta can make people suffering from herpetic dermatitis allergic to iodine.

In the cold winter, people often feel uncomfortable because of the cold, and some people are particularly afraid of the cold because of the weak yang in their bodies. Therefore, in winter, it is necessary to use food with cold-proof function to keep warm and recuperate, so as to warm and nourish the whole body tissues, enhance physical fitness, promote metabolism, improve the cold-proof ability of the human body, maintain the normal function of the body tissues, resist external evils and reduce the occurrence of diseases. traditional Chinese medicine

Scientists believe that we should eat warm and nutritious food in winter. Such as mutton, dog meat, turtle, sparrow, shrimp, pigeon, quail, sea cucumber, medlar, leek, walnut, glutinous rice and so on.

Increase thermogenic nutrients

Due to the cold climate in winter, the human body consumes more energy every day to adapt to the cold environment, so it is necessary to increase the intake of thermogenic nutrients. Thermogenic nutrients mainly refer to protein, fat and carbon hydrate. Therefore, we should eat more foods rich in these three nutrients, especially increase the intake of some fat, such as putting a little fat when eating meat dishes and putting more cooking oil when cooking.

Methionine supplementation

Methionine can provide a series of methyl groups necessary to adapt to cold tolerance through transfer. The cold climate increases the excretion of creatine in human urine and accelerates the metabolism of fat, while the heat released by the synthesis and oxidation of creatine and fatty acids in human body needs methyl. Therefore, we should eat more methionine-containing foods in winter, such as sesame seeds, sunflower seeds, dairy products, yeast, leafy vegetables and so on.

Vitamins can't be less

Due to the cold climate, the oxidation heat production of human body is strengthened, and the vitamin metabolism of human body has also changed obviously. For example, increase the intake of vitamin A and enhance the cold tolerance of the human body. Increasing the intake of vitamin C can improve the adaptability of human body to cold, which has a good protective effect on blood vessels. Vitamin A mainly comes from animal liver, carrots, dark green vegetables and other foods, and vitamin C mainly comes from fresh fruits and vegetables and other foods.

The minerals should be suitable.

People's fear of cold is also related to the quality of minerals ingested by the body. For example, the content of calcium in the human body can directly affect the flexibility and excitability of the heart, blood vessels and muscles, and calcium supplementation can improve the cold resistance of the human body. Foods rich in calcium include milk, bean products and kelp. Salt is also very important for human body to keep out the cold, which can enhance the heat-producing function of human body. Therefore, in winter, it is mainly heavy taste and pungent heat, but it should not be too salty, and the daily salt intake should not exceed 6 grams at most.

Wear a mask to keep out the cold. There are abundant blood vessels and spongy vascular network in the nasal mucosa, and the blood circulation is very strong. When cold air is inhaled into the lungs through the nasal cavity, it is generally close to body temperature. The cold tolerance of human body should be enhanced through exercise. If you wear a mask to keep out the cold, it will make your body delicate and more likely to catch a cold. ?

Sleep with your head covered. Burying your head in the bed will make you feel warmer, but the oxygen in the bed will be less and less, and carbon dioxide and unclean gas will accumulate more and more, so people who sleep with their heads covered will feel groggy and exhausted after waking up. ? Wash your face with hot water in winter. Under the stimulation of cold air, sweat glands and capillaries contract. When it meets hot water, it expands rapidly, but after releasing heat, it returns to the state at low temperature. Such capillary contraction is easy to cause wrinkles on people's faces.

Drink to keep out the cold. After drinking, I feel warm all over, which is the result of alcohol prompting the human body to emit primitive heat energy. After drinking, a lot of heat escapes from the body, which makes people get goose bumps all over, leading to a cold after drinking. ?

Freeze your hands and feet and bake them with fire. Exposing hands and feet for a long time in winter causes blood vessels to contract and blood flow to decrease. At this time, if it is baked with fire immediately, the blood vessels will be paralyzed, lose their contractility, and there will be arterial congestion, capillary dilation, enhanced permeability and local congestion. Mild frostbite, severe tissue necrosis. Therefore, frozen hands and feet can only be gently rubbed to make them slowly return to normal temperature.

Scratch itchy skin with your hands. When you feel itchy all over because of dryness in winter, don't scratch it with your hands, otherwise it will easily scratch your skin and cause secondary infection. The prevention method is to drink more water, eat more fresh vegetables and fruits, eat less spicy food such as hot and sour, and drink less. Take a bath frequently and change your underwear frequently. Those with severe itching can take chlorpheniramine, phenamine and other drugs, or apply calamine lotion or soothing ointment for treatment.

When the cold wind blows in winter and the weather is dry, dry skin will lose moisture more easily unconsciously. During skin care, avoid the following skin care procedures:

1, use alcoholic cosmetics, such as toner or lotion. Because alcohol easily volatilizes moisture and oil from the skin, it is advisable to use water-based toner instead.

2. Use cleansing products with strong degreasing ability: especially for dry skin, use mild cleansing milk or oily soap.

3, wash your face with hot water: hot water has a strong deoiling effect, wash your face with hot water, wash away skin oil, water is easy to lose, and the skin is drier and more itchy.

4, the indoor temperature is too high: when the indoor temperature is too high, the indoor relative humidity will drop, and the moisture of the skin is easy to lose.

5. Dry your body immediately after taking a shower: it is not suitable to dry your face and body with a towel after taking a shower, and take a shower when it is cold. Without warm water, everyone will quickly dry their bodies and put on clothes. But to prevent dry and itchy skin, you should apply moisturizing oil and lotion to moisturize when your body is half dry.

Matters needing attention in self-treatment

(1) Take an active part in sports activities to speed up the circulation of qi and blood, which is conducive to the repair of sores. It can also prevent frostbite from happening again.

(2) Pay attention to cold protection and warmth in cold season.

(3) Clothes, shoes and socks should be loose and dry.

(4) Those who relapse every year can gradually develop the habit of washing their faces, feet, wiping their bodies and taking a bath in cold water in summer to improve their cold tolerance.

(5) People who are afraid of cold in winter can eat more hot cold-dispelling foods, such as mutton, dog meat, venison, pepper, ginger and cinnamon.

(6) Those who get sick every winter can be cured in summer. Repeated external rubbing and conditional infrared physiotherapy self-treatment have better effects in dog days. We should treat both internal and external problems as early as possible before winter.

It is not advisable to heat it with hot water or bake it with fire after freezing, otherwise the frozen place will fester.

After freezing, the skin is itchy, so you can't scratch it by hand, otherwise it will easily make the epidermis tattered and infected.
