Postpartum sweating can usually be relieved in about a week, but there are some individual differences in each person, and the duration varies from person to person. One week after delivery, the skin excretory function is vigorous, will discharge a large amount of sweat, to sleep at night and the first waking up more obvious, which is generally referred to as sweating. During pregnancy, due to hormonal effects, the body tissues produce more sodium, potassium, and chlorine retention, resulting in water retention in the body. In the postpartum period the excess water will be eliminated through puerperal sweating and urination. In addition, excessive sweating during the puerperium is not a pathological condition, but simply a positive physiological way of metabolizing excess water and reducing the burden of increased blood volume during pregnancy. However, if the mother sweats a lot, care should be taken to prevent dehydration, and if the temperature is too high, care should be taken to prevent heat stroke.
