2. Skin itching may be caused by weather changes. In addition to humid weather, the climate is cold and dry in winter, and human skin becomes dry and rough, and even the epidermis peels off, which can easily stimulate the nerve endings in the skin and cause itching. Skin itching can be divided into localized and systemic. The most common localized itching is skin itching of the vulva, perianal area, and scalp. Systemic pruritus can be divided into senile, seasonal, etc. For example, winter pruritus is more common in winter.

3. Skin itching may be caused by mosquito bites, which can lead to insect bite dermatitis and produce itching symptoms. Or it may be due to food allergies. For example, certain foods such as seafood, beef and mutton, or some fruits such as mangoes can easily become allergens, causing skin itching.

4. Skin itching may be caused by the patient's contact with some physical or chemical stimuli.
