There is no such thing as exercising to discharge blood during menstruation. Menstruation is caused by the cyclic shedding of the uterine lining in response to hormones, and is manifested in the form of vaginal blood discharge as well as cyclic uterine bleeding. The first day of bleeding is the beginning of menstruation, and the time between the first day of two menstrual bleeds is called the menstrual cycle. In general, the normal menstrual cycle is 28-35 days, and the onset of menstruation takes about 3-7 days. Normal menstrual blood is odorless, non-clotting, and dark red in color. Women need to pay attention to hygiene during menstruation and change sanitary napkins regularly to avoid infection. In terms of diet, eat warm and nutritious food in moderation and avoid cold and irritating food. In addition, pay attention to keep warm and keep a happy mood.
