Sweating at the back of the neck is commonly caused by accelerated blood circulation and autonomic dysfunction. 1. Accelerated blood circulation: Strenuous exercise, drinking hot soup, high ambient temperature and other factors may cause accelerated blood circulation, which in turn increases the body’s metabolic level, thus generating more heat. The body needs to stabilize the body temperature, it needs to sweat to release the body heat, so the back of the neck has sweating symptoms. 2. Autonomic dysfunction: Tension, anxiety, low blood pressure and other factors may cause autonomic dysfunction of the body, which leads to abnormal secretion of sweat, clinically manifested as sweating at the back of the neck. Hypoglycemia can be relieved by replenishing sugar, and adverse emotional factors such as tension and anxiety need to be improved by improving one’s psychological quality or diverting one’s attention. If the symptoms of sweating behind the nose continue to be unrelieved or aggravated, you should go to the hospital in a timely manner to clarify the cause of the disease and then carry out targeted treatment.
