You can steam 3 days after your menstruation. Steam after your menstruation can promote your body’s metabolism and make your body sweat a lot, which can discharge toxins from your body, which is good for your body. This is because on the first day of menstruation, the endometrium is not shed and the cervix is not completely closed, which can cause bleeding again due to blood circulation or contraction of the uterus. During the menstrual period, you should not steam, as it can cause increased menstrual flow and prolonged menstrual period, because it can promote blood circulation and accelerate blood flow, which can affect menstrual flow. If you have low menstrual flow or dysmenorrhea, you can steam before your period, which can improve the symptoms of dysmenorrhea and increase menstrual blood.
