Grumpiness during menstruation is mostly caused by a decrease in the level of hormone secretion in the body and a shortage of estrogen and progesterone. Avoid straining during this period, eat more fresh fruits and vegetables, drink more water, eat more beans or soy products and protein-rich foods, and forbid eating cold, spicy and stimulating foods. Listen to more soothing music, chat with family and friends to relax, take a moderate walk every day to increase body resistance, live a regular life, do not stay up late. During menstruation, pay attention to keep warm, avoid getting cold, keep your pubic area hygienic and clean, change your underwear regularly. During menstruation, sexual intercourse should be prohibited to avoid bacteria entering the pelvic cavity, which can lead to pelvic congestion and induce gynecological diseases such as pelvic inflammatory disease and adnexitis.
