Hello. During menstruation, it is recommended to pay attention to daily rest, keep warm, and daily cleaning and hygiene, and not to eat irritating food. It is suggested that strenuous exercise (including running and sex life) should be prohibited. Otherwise, it will cause irregular menstruation, delayed menstruation for one month, dysmenorrhea and rupture of ovarian corpus luteum (causing massive bleeding). It is advisable to walk continuously for 20 minutes every day during menstruation. I wish you all the best, health, happiness and happiness. Please adopt it. Thank you.
