The physiological period is the time period when menstruation usually occurs, because after puberty, menstruation is a physiological phenomenon, so it is commonly known as the physiological period. During the menstrual period, the body’s resistance decreases and the endocrine content is low, so we should pay attention to regular rest and rest, not to stay up late, avoid mood swings and avoid stress, so as not to affect the endocrine. In addition, you should pay attention to keeping your lower abdomen warm during menstruation to avoid dysmenorrhea, and you should also pay attention to eating more fresh vegetables and fruits and high-protein foods during menstruation. If the menstrual period is less than 3 days, the menstrual flow is low and needs to be checked. If the menstrual period is more than 7 days, the menstrual flow is prolonged, which is mostly due to luteal insufficiency and should be checked.
