How is it that the whole body itches when the body is hot in winter?

In winter, when the weather is cold, we all wear thick clothes to keep warm to prevent frostbite. The climate in winter is still relatively dry, and our skin will inevitably dry and peel, and sometimes it will itch. Some people say it itches when it's hot. What is the reason? Why does the whole body itch when the body is hot? .

1, itching caused by sensory nerve endings in sensitive skin

Winter xerosis cutis

There is no rash on my body, probably because my skin is too dry. When the skin is short of water, it will become fragile and sensitive, and it will also increase the sensitivity of the skin to sensory nerve endings.

Electrostatic stimulation

When the skin is dehydrated and dry, static electricity cannot be released in time, and staying on the skin surface will stimulate the skin, which is also one of the reasons for skin itching. Some people like to wear chemical fiber clothes, which are equivalent to fur rubbing sticks, which are easy to generate static electricity and cause itchy skin.

Hot and cold stimulation

When the weather is cold and dry in winter, the capillaries on the skin surface contract, and when the body is heated, the capillaries will expand again. The tactile nerve endings distributed on the skin surface are very sensitive, and slight friction or stimulation can cause itching. Although the blood vessels are expanding, it is a kind of stimulation to the nerve endings on the skin surface, so there is an itchy feeling.

Summary:

When sweating, some people will feel tingling for the same reason, all because of the increased sensitivity of sensory nerve endings. Dry skin and changes in climate, temperature and environment are all factors that lead to the sensitivity of skin sensory nerve endings.

2, allergic skin itching.

When allergic symptoms are mild, there is generally no rash, but the skin will still feel itchy. For example, some people are allergic to mango juice, yam mucus, or shower gel, and itching symptoms will appear when they come into contact with it. You can check whether you have been exposed to allergens recently.

3, cold urticaria causes itching.

The demands are all factors that may lead to itchy skin without rash on the body. But when the skin itches in winter, it is sometimes accompanied by some rashes, which can be considered as cold urticaria.

Cold urticaria mostly occurs in winter, which is related to physical fitness. Cold air in winter is one of the causes of urticaria, and eating food stimulated by cold may also induce itching symptoms. When it comes on, it will be accompanied by slight fever of the skin.

4, skin moisturizing tips

1. Cold boiled water has a better water supply effect than hot boiled water. Drinking more water every day helps to keep the easily lost water at the best level.

2. Drink a cup of cold boiled water before taking a bath or shower to prevent heat from quickly evaporating moisture under the skin.

3. Skin care products contain vitamins, and the moisturizing effect will be more obvious. Vitamins A, B 1, B2, B6, C, E, F and H are all good.

4. Night is the time to strengthen skin permeability. Get enough sleep, and your skin will become watery after getting up.

5. Fruit can supplement water and vitamins, deeply moisturize the skin, and of course it can't be omitted. However, eating fruits with high sugar content will consume water, and less sweet fruits such as oranges, strawberries and grapes may wish to eat more.

6. When you sleep more than 12, the water in your skin will be pumped out, so people who often stay up late have the problem of loose skin and lack of water.

7. Drink a small glass of red wine before going to bed, the blood circulation is accelerated, and the skin's absorption of moisturizing products is obviously increased.

8. Leave the computer for 5 minutes every 1 hour and let the skin rest for a while.

9. In winter, we should gradually increase the use of moisturizing essence, aromatic essential oil and anti-wrinkle cream to "supplement".

10. 2-3 times a week, use a moisturizing mask to protect dry skin, especially in winter, and a hydrating mask is essential.
