It is not recommended to drink beer during menstruation, but if you really want to drink beer, it is okay to drink a small amount of beer once in a while, there is no great adverse effect on the body, so be careful not to drink a lot or drink cold beer. Women are weaker and less resistant during their periods, so drinking a lot of beer or drinking cold beer will speed up blood circulation and stimulate the gastrointestinal tract, which may lead to increased menstruation, prolonged periods and menstrual cramps and other uncomfortable symptoms. Moreover, women are more susceptible to the effects of alcohol than men. Women have a higher chance of liver damage and alcohol poisoning from alcohol consumption than men because women have relatively fewer enzymes involved in alcohol metabolism and a weaker ability to break down ethanol. Women who drink alcohol during their periods will be relatively longer intoxicated. This is because during menstruation, the level of sex hormones will increase, and under the influence of sex hormones, the enzymes that metabolize alcohol in the female body will decrease, and their activity may also decrease, which will lead to a slower decomposition of alcohol in the body, and at the same time, some of the alcohol is decomposed into acetaldehyde, which cannot be excreted in time, and acetaldehyde will accumulate in the body, which will easily cause liver damage. During menstruation, women may feel agitated, tired, etc. Occasionally drinking a small amount of room temperature beer may have a certain effect on relieving bad mood. However, you should not drink a lot of alcohol or drink cold beer, and you should not drink alcohol for a long period of time to avoid damage to your body from alcohol.
