Eczema will grow on the buttocks if you sit for a long time. It is recommended to avoid sitting for a long time, wear loose clothing, and keep the buttocks clean and hygienic. Most of the eczema is due to the body’s internal causes, allergen stimulation, environmental temperature and other factors, the patient if only once in a while sedentary situation, usually does not directly lead to eczema. If the patient is sedentary for a long period of time, it will cause the temperature of the buttocks to continue to be too high, which will breed bacteria and may cause eczema, pimples, itching and other uncomfortable symptoms. Avoid sitting in the same place for a long time and for too long in your daily life or work and study. You should move around appropriately, wear loose and breathable clothing, and wash your buttocks regularly to ensure that they are hygienic and dry. It is recommended that patients with buttock rash or itching symptoms should consult a doctor in time and follow the doctor’s instructions.
