Sweating in the summer may be caused by physiological factors such as hot weather, but it may also be related to hyperhidrosis, hyperthyroidism and other diseases, which can be improved through medication, surgery and other ways. 1. Physiological factors: If the summer sweat is caused by hot weather, it is recommended to avoid going out when the weather is hot, so as not to aggravate the degree of sweating. At the same time, drink more water to replenish the body’s loss of water. 2. Hyperhidrosis: Hyperhidrosis may also lead to particularly heavy sweating in the summer, patients can be used externally with aluminum acetate solution, aluminum chloride solution and other drugs; for mental factors caused by hyperhidrosis, you can take phenobarbital, bromine and other drugs to inhibit the secretion of sweat. For patients whose conservative treatment is ineffective, sympathetic nerve block can be chosen for treatment. 3. Hyperthyroidism: summer brain sweating especially may also be caused by hyperthyroidism, patients can take prothioxythiophene, formamide imidazole and other anti-thyroid drugs, can inhibit the synthesis of thyroxine. For moderate or severe hyperthyroidism, the thyroid gland can be surgically removed. If the brain sweats particularly much in summer, after excluding physiological factors, it is recommended to go to a regular hospital for examination and treatment under the guidance of a doctor.
