Why is it rainy and cool, and the skin itches?

There should be only two reasons for itchy skin. First, you have skin problems, such as tinea, and you need to take medicine to see a doctor. Second, itching caused by too dry skin, the main phenomenon is that there will be tiny dry dandruff, and there will be red spots after scratching.

If it is the latter, I suggest you reduce the number of baths in spring, autumn and winter, just 1-2 times a week, and then it is best to control the water temperature (no more than 40 degrees) to be close to the human body and reduce the number of exfoliations. Because these three seasons are inherently dry, bathing will take away a lot of water in the body, so it will be helpful to reduce the number of baths appropriately. When choosing daily cleansing products, you must not use deep cleansing products, which will take away too much oil and moisture from the skin and easily lead to water-oil imbalance. Even if you choose a deep cleansing product, you can use it once a week, otherwise it will make your skin worse. The second is to apply water and lotion in time after cleansing and bathing to lock the skin moisture. Dry parts can be applied many times.

You can put a humidifier in your home or office every day to reduce the evaporation of skin moisture caused by air drying. Close-fitting clothes are best made of pure cotton, which is slightly loose and breathable. Drink more water, eat more fruits and vegetables, avoid spicy food, rest and reduce the number of staying up late to ensure the quality of sleep.
