Sweating on the face can be caused by physiological factors such as high sympathetic excitability or diseases such as hyperthyroidism and cholinergic urticaria. 1. Physiological factors: high sympathetic excitability, sympathetic excitability will lead to sweat secretion from the sweat glands of the face, resulting in facial sweating, which is a normal physiological phenomenon. 2. Hyperthyroidism: the thyroid gland synthesizes and releases too much thyroid hormone due to various factors, resulting in hypermetabolism and sympathetic excitability, which may cause palpitations, easy sweating, increased eating and bowel movements, and weight loss. 3. Cholinergic urticaria: common in heat, exercise, nervousness, eating hot drinks or alcoholic beverages, the core temperature of the body rises, prompting the role of acetylcholine in the mast cells and the onset of the disease, which can lead to the emergence of easy sweating face, skin hives symptoms. There may be other reasons for easy sweating on the face, and it is recommended that patients go to the hospital if necessary to clarify the cause of the disease and follow the doctor’s instructions for treatment.
