Sweating after drinking is caused by the following three factors: First, after drinking, the body’s alcohol will be converted into ethanol, ethanol in the liver under the action of ethanol dehydrogenase decomposition into acetaldehyde, acetaldehyde is a kind of perimeter capillaries and aortic vessels with expansion of toxic and harmful substances. When the blood expands, the blood vessels speed up the blood flow, and this will lead to a large amount of sweating and an increase in metabolic rate. Secondly, the heart rate accelerates after drinking alcohol, resulting in a surge in the body’s basal metabolic rate, which can also lead to a lot of sweating due to excessive heat production. Third, if the heat production is not effectively replenished with glucose and glycogen in time, the body will soon fall into a period of hypoglycemia. When the blood sugar is lower than 3.9mmol/L, hypoglycemic reaction will occur, and the most typical symptom of hypoglycemic reaction is the clinical manifestation of dripping sweat.
