Drinking beer shivering, cold shiver usually have the following factors: First, the most common factor is hypoglycemic reaction, when people drink too much alcohol, the body belongs to the body’s negative nitrogen balance, decomposition consumption is greater than the intake and utilization, so there will be a hypoglycemic reaction, at this time the body will consume a lot of heat and calories, metabolize too much sugar, will produce hypoglycemia, especially when people hypoglycemia will appear shivering, cold and other clinical symptoms. Secondly, when alcohol enters the bloodstream transiently, it will expand the blood vessels of the body, especially the capillaries, arteriovenous short circuit and microcirculation, and the microcirculation will appear cold, shivering and cold trembling when it expands excessively. Thirdly, if alcohol is consumed in excess, the ethanol in alcohol will be decomposed into acetaldehyde under the action of liver ethanol dehydrogenase, and acetaldehyde has a chemical that dilates the peripheral capillaries and produces toxins, which will accelerate the body shivering and produce cold.
