Can women still exercise after menstruation? During the menstrual period, because the basic tension of the uterus in menstrual period is higher than that in non-menstrual period, the contraction frequency increases, and uncoordinated or irregular contraction often occurs, which reduces the blood flow of the uterus and leads to ischemia and pain. Moreover, the uterus will synthesize prostaglandin, and some hormones that promote uterine contraction will increase, which will also reduce uterine blood flow, ischemia and hypoxia, and secrete some vasopressin and oxytocin, which can increase uterine activity and so on. During menstruation, individuals will show irritability and depression, and may secrete luteal phase. Estrogen and progesterone can promote endogenous opioid peptides. When menstruation comes, the luteal phase drops sharply in the later period, forming a rapid withdrawal reaction, causing some mental abnormalities during menstruation, such as fatigue and tension. Proper exercise and activities during menstruation can reduce pelvic congestion and reduce bad emotions, such as backache, fatigue and other abnormal emotions, which are good for women. But the amount of exercise should not be too large, and the range of exercise should not be too intense, because too intense will aggravate pelvic congestion and dysmenorrhea. And sometimes it will cause the oviduct to creep backwards, leading to the blood in the uterine cavity running into the abdominal cavity, forming endometriosis and so on. Moreover, during menstruation, women's resistance is relatively low, and strenuous exercise is easy to produce unfavorable conditions for women. As can be seen from the above, women can't exercise after menstruation.
