Menstruation is a special physiological period for women. During menstruation, women suffer from a lack of blood, poor body immunity and pelvic congestion due to constant bleeding, and drinking beer can activate blood stasis and increase menstrual volume, prolong menstruation and endocrine disorders causing menstrual disorders. The number of alcohol-degrading enzymes produced by the body of women during menstruation will decrease, and alcohol will accumulate in the body for a longer period of time, which will easily cause prolonged intoxication. Women should pay attention to rest during menstruation, keep warm, eat a warm and light diet, increase the intake of high nutrients appropriately, and avoid cold, spicy and stimulating foods.
