Badminton is not allowed to play during menstruation. Badminton is a strenuous sport, and playing badminton during menstruation will stimulate the uterus to contract, which will cause menstrual blood to flow down the fallopian tubes and into the pelvic cavity. Menstrual blood contains endometrial fragments, which once left in the pelvic cavity will be planted in one of the pelvic organs, which will cause endometriosis, resulting in pain in the lower abdomen during menstruation, and this pain is gradually aggravated, and may also lead to infertility in clinical practice. Therefore, it is not recommended to play badminton during menstruation, but to take an appropriate walk during menstruation, which will not affect the body accordingly. In addition, vigorous exercises such as running and jumping rope should not be done during menstruation, as they may lead to endometriosis, and clinical attention should be paid to them.
