Menstruation is the cyclical withdrawal of hormone levels in the body, causing the endometrium to shed and bleed, which is a normal physiological phenomenon that stimulates female metabolism and enhances blood production. If the hormone level in the body is disturbed, it causes menstruation to lose its original regularity and become irregular, manifesting as early or delayed menstruation. Menstruation is also influenced by the uterus, which can be abnormal due to malformation of the uterus and endometrial adhesions. During menstruation, women’s immunity decreases and infection is easily induced. During this period, women should pay attention to vulva hygiene, change sanitary napkins regularly, wear loose cotton underwear, eat a light diet, do not eat cold food, do not eat spicy and stimulating food, do not overwork, pay attention to rest, drink more hot water, and be properly active.
