Common causes of ear sweating are: 1. Hair follicles or sebaceous glands behind the ears secrete more vigorously, and the secretion of sweat glands increases in hot summer months or after strenuous exercise, so sweating behind the ears is easy. It is recommended to pay attention to the cleaning of the ear area in general to keep the local area clean and dry to avoid local pore blockage, so as not to aggravate the symptoms of sweating behind the ear. 2. Patients with kidney yin deficiency tend to show external heat and tend to sweat profusely, and their ears also show sweating, so it is recommended to take Liu Wei Di Huang Wan for treatment. Ear sweating can also occur when taking antipyretic drugs that cause the organism to sweat a lot. Pay attention to swabbing the sweat away in time and pay attention to hydration.3. If other causes of simple ear sweating are ruled out, consider it to be localized hyperhidrosis. There is no particular treatment for this, so just wipe the sweat away in time and keep the area clean and dry.
