Postpartum sweating in women can last for 1-4 weeks, with individual women experiencing false sweating for 2-3 months after delivery. In order to feed the physiological needs of the mother and the fetus, the blood circulation of a woman during pregnancy increases by 20%-30% compared to the non-pregnant state. After delivery, the supply of nutritional needs decreases and the circulating blood volume decreases accordingly, so the patient will reduce the vascular volume in the form of sweating after delivery. Patients sweat the most within a week after delivery, and after a week, the amount of sweating will gradually decrease, and the physiological sweating will disappear completely within about a month after delivery. If the patient still has persistent sweating after one month, it is related to the clothes the patient wears or the weakness of the body, and must be regulated, as persistent and prolonged sweating is not good for the patient’s health, and it also tends to reduce breast milk.
