Why is the skin easy to itch in winter?

1, dry

In summer, you sweat a lot and your skin is moist. In winter, the air becomes cold and dry, the amount of sweat secreted by sweat glands and sebum secreted by sebaceous glands decreases, the water content of the skin also decreases, and the wettability of the skin decreases, indicating that the skin is dry, and dryness is more likely to cause skin itching.

2, skin diseases

If you have skin diseases, such as urticaria, contact allergy, eczema, psoriasis and other skin diseases, it will often get worse in winter, leading to itchy skin.

3. Other diseases

Some diseases can also cause skin itching, such as diabetes, hepatobiliary diseases, kidney diseases, renal failure, hyperthyroidism, vitamin deficiency, neurological dysfunction and some tumor diseases. Itching caused by these diseases is generally accompanied by the symptoms of the disease itself.

Avoid doing this when the skin itches in winter.

1, take a bath often

Some people usually form the habit of taking a bath every day, but they are still used to taking a bath every day when it is cold. If you take a bath every day at this time, the lipid film on the skin surface and the lipid in the stratum corneum will be removed more easily. It is very comfortable to wash, but it will be more itchy in the later stage and prone to a vicious circle.

Step 2 take a bath

Friction will not only reduce sebum, but also destroy the stratum corneum in severe cases, further reducing the moisturizing function of the skin and aggravating the occurrence of itching.

3. The bath water is overheated

Excessive water temperature will also accelerate the loss of skin moisture and oil. And burns can also stimulate nerve endings of the skin, making the skin more itchy. Therefore, as long as the water temperature is controlled slightly higher than the body temperature, you will feel that the water is very warm and will not feel hot.

4. Bathing time is too long

Many people are afraid that they are not clean every time they take a shower, especially some neat women. Bathing time is often more than half an hour, and some even an hour. Washing for too long will inevitably wash away more sebum film on the surface of human body, followed by itching. Suggestion: the bath time should not be too long, but 5 ~ 10 minutes is better.

How to relieve skin itching in winter?

1, apply moisturizing cream

I just took a shower and my skin is still wet. At this time, body lotion can generate hydration and achieve the best moisturizing effect. Some people with dry skin, it is best to apply some emollients with moisturizing function to the body within 5 minutes to keep the skin moist, prevent dry skin and reduce the occurrence of skin itching.

2. Choose cotton, loose and close-fitting clothes.

Try to choose cotton-padded jacket, which is not easy to generate static electricity, as underwear in winter, and avoid sweaters and chemical fiber clothes.

Step 3 drink plenty of water

Drinking more water is the most direct way to replenish water. Adults need at least 4000 ml of water from diet and drinking water every day, and drink more water in winter. Although there is no regulation on how many glasses of water to drink every day, you should get into the habit of drinking water. Don't be afraid to run to the toilet often, and don't feel thirsty or dry is the most basic requirement. Never drink water after you are thirsty, which shows that your body is already in a state of water shortage. Of course, in addition to drinking more water, you can also eat more liquid foods to replenish water to your body, such as soybean milk, milk, porridge, clear soup and so on.

4. Vitamin supplements

Scientific research shows that the lack of vitamin A in the body can easily lead to itchy skin, peeling, rough and dry hair, night blindness and so on. At this time, you can eat foods rich in vitamin A such as animal liver and eggs, and you can also eat foods rich in water and vitamins such as fresh fruits and vegetables, milk and soybean milk.

5. Eat more fresh fruits and vegetables.

In winter, people prefer to eat heavy-flavored food rather than fresh vegetables, and fresh fruits and vegetables are also scarce, which easily leads to the lack of water-soluble vitamins such as vitamin C and B vitamins.

It is suggested that the daily intake of fresh vegetables should be kept at 300-500g, of which at least 1 serving is green leafy vegetables; And about 300 grams of fresh fruit. Vitamin supplementation can also supplement dietary fiber and improve gastrointestinal function.

6. Eat less spicy food.

It is cold in winter, and the body's resistance is easy to get sick. It can't be ignored to replenish energy and maintain the body in time. However, in winter, frequent consumption of high-fat, high-protein, heavy drinking and spicy food to increase calories will easily lead to yin deficiency and excessive fire, and gastrointestinal stagnation, which will lead to gastrointestinal dysfunction, dry stool, dry and itchy skin, etc.
