In case of vaginal delivery, the physiological recovery period is 56 days, and it is recommended that it is best to consider blowing fans after 2 months. This is because throughout the puerperium, pregnant women sweat more, and after pregnancy, the blood volume increases, and after delivery, the blood volume is restored to normal by sweating. In case of cesarean delivery, the physiological recovery period is 3 months, so blowing fans can be considered after 3 months. If the physiological recovery period has not passed, the body’s hormone level and other internal organs have not returned to the state of non-pregnancy, so if you blow the fan too early, it may lead to discomfort. It is also recommended that if the weather is hot, it is best to turn on the air conditioner, and it is recommended that the temperature should be around 26 degrees, which is the most suitable temperature, and that the air conditioner should not blow against the body.
