What is the reason for skin rash and itching in autumn?

In autumn, many people will have local skin itching, mainly on the limbs or the whole body. Generally, it is light during the day and heavy at night, especially when they take off their clothes and sleep. Patients will feel itchy and paroxysmal, such as insects crawling, ants walking or burning. Serious people can't help scratching during the day, which affects normal work and life. In order to prevent skin itching, we might as well pay attention to food, clothing, housing and transportation.

Clothing: underwear should be kept clean, and underwear should be soft and loose, preferably cotton. Avoid wearing close-fitting down, nylon and woolen clothes. Nylon and wool fabrics are prone to static electricity, and cells on the surface of human body will be uncomfortable because of the stimulation of static electricity.

Food: pay attention to the regulation of gastrointestinal function, with light fresh vegetables and bean products rich in vitamins as the best; Taboo cigarettes, alcohol, peppers, strong tea, coffee and other irritating foods; Keeping the stool unobstructed can effectively and timely expel allergens accumulated in the body.

Residential: The indoor temperature should be adjusted to 16℃ to 20℃ in autumn and winter, with a relative humidity of 30% and a maximum of 40%. If the relative humidity is lower than 20%, it is necessary to make adjustments, such as sprinkling some water on the ground and buying a humidifier if possible.

OK: We should reduce outdoor activities in autumn and winter. A large number of dust, pollen and smoke particles in the air become charged bodies due to friction induction, which will also cause skin reactions. After a whole day's activities, there will be a lot of static electricity between underwear and skin, and electrostatic discharge will occur when undressing, and the skin will be highly itchy because of the sudden change of electrostatic field.
