Easy sweating in summer may be caused by physiological reasons, hyperthyroidism, calcium deficiency and other factors, which can be treated by propranolol hydrochloride tablets, vitamin D and other drugs. 1. Physiological reasons: when the temperature exceeds 35 degrees, the human body can no longer dissipate heat through radiation and other means, resulting in easy sweating in summer, which is a normal phenomenon, generally no need to deal with. 2. Hyperthyroidism: due to the abnormal secretion of thyroxine, causing the body’s metabolism to increase, leading to the symptoms of easy sweating in summer. It can be treated with medicines such as propranolol hydrochloride tablets and methimazole tablets. 3. Calcium deficiency: In particular, a decrease in the concentration of calcium in the blood can cause sympathetic nerve excitation, leading to easy sweating in summer. Calcium-containing preparations such as vitamin D and calcium gluconate can be supplemented appropriately to alleviate the symptoms. Patients who are prone to sweating in summer are advised to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give appropriate treatment or therapy.
