Why does the skin of arms and thighs itch in winter?

Honey, it's seasonal dermatitis. I tell you with the onset of the disease in the past ten years that I have taken countless medicines and injections, but I can't eradicate the disease. Every autumn and winter, when the weather is cold and dry, it will recur immediately and begin to itch. I mainly have two legs, and almost all of them are scratched from the calf to the thigh. Eat whatever you itch, Park Min, and a bunch of anti-allergic drugs. You can take it immediately for one night and start again the next day, and so on. After a long time, I gradually found that this happens only when the weather suddenly turns cold or cold and dry. I started looking for information on the Internet and found that many people mentioned that vitamin deficiency was related to normal maintenance. I want to share my experience with you, hoping you can relieve the pain as soon as possible:

1. People with seasonal dermatitis should not take a bath frequently (once every 3-4 days is enough), and the water should not be too hot. Maybe washing hot water will relieve itching, but it will hurt more at night after washing. The reason is that bathing will wash off the oil on the skin and the skin will be dry. Dry skin or dry skin is one of the pathogens.

2. Be prepared to prevent dry skin in early autumn. Wipe the driest part of the skin with moisturizing lotion after each bath (it is also recommended to keep the skin moist every day when you don't take a bath), especially where it itches every year (it is recommended to use Baiqueling antipruritic lotion, which is cheap and easy to use). It is important to remember to use it in advance when you feel dry in autumn, and the effect will be better.

3. Eat vitamins, what to eat? Do not take medicine, buy an orange to eat every few days, supplement vitamin C, remember not to buy oranges, be sure to buy oranges to eat.

4. Pay attention to personal dress. Try to buy cotton-padded jacket inside. Clothes made of other materials are prone to static electricity and itching when rubbed against the skin.

5. Pay attention to personal sheets and change the sun frequently (taking it out in autumn and winter can kill mites and is also a factor that causes itching).

Of the above five points, I think the first three are the most important. We must adhere to the above, which will not be good. But if you insist on doing this, you will find that your seasonal dermatitis will not recur. I haven't had a relapse for four years now, but I must stick to the above five points every year, or I will have a relapse. There is no cure for this disease. I don't need an injection or medicine. Personally, I think this method is the safest and most reliable, and countless friends around me have used it.
