During menstruation, you can use a hair dryer to dry your hair after washing it. Because women’s bodies are weaker and less resistant after giving birth, if they wash their hair, it is easy to catch a cold and cause a cold. However, if you use a hair dryer to dry your hair immediately after washing it, your body will quickly enter a warm state, and as long as the temperature is suitable, i.e., the room is not too cold, you won’t catch a cold. It is important to pay attention to skin hygiene and perineal hygiene after delivery, and it is also possible to take a bath during the postpartum period. If you have a normal delivery, you can usually take a bath after one week. As there are more secretions from the body at this time, it is easy to cause skin infections, so be sure to keep your skin clean.
