Head sweating after head surgery may be caused by the following two reasons: first, post-operative infection and fever. Fever will cause the pores of the sweat glands of the skin to expand and increase sweating in order to take away the heat from the body and lower the body temperature. Second, plant nerve dysfunction. When surgery injures the plant nerve center of the hypothalamus, or when bleeding or increased intracranial pressure after surgery stimulates the plant nerve of the hypothalamus, it will lead to plant nerve dysfunction, and plant nerve innervation of gland secretion will lead to increased sweat secretion, thus causing sweating, and body temperature is often normal in this case. For head sweating after surgery, if it is caused by postoperative infection or fever, it should be strengthened to fight infection and control body temperature. If the sweating is caused by plant nerve dysfunction, there is no special treatment, and sweating can be stopped slowly after the plant nerve function is restored, and a dry towel should be dried in time during sweating to prevent catching a cold and causing infection and fever.
