The following are some of the dangers of getting angry when a woman has her period: First, it may lead to endocrine dysfunction in women, because when women are angry, it can lead to abnormalities in the secretion functions of the liver, kidneys, pituitary gland, ovaries, endometrium and vagina. In particular, the ovaries secrete estrogen, sex hormones, follicle stimulating hormone, these hormones may appear abnormal, and these hormones play a vital role in regulating the normal formation of menstruation as well as the secretion process, so during menstruation, anger is most likely to lead to menstrual disorders, and even dysmenorrhea, etc. Second, the uterus and ovarian function can play a certain destructive role, because when people are angry, it will cause sympathetic excitement, which will lead to an increase in the body’s adrenaline, norepinephrine, etc. The content of these hormones can also act on the uterus, ovaries, vagina, etc., resulting in significant changes in the metabolic function of these organs, thus causing abnormal physiological functions.
