A woman can go out 20 days after delivery, but she should be well prepared, pay attention to sun protection and warmth, and prevent from getting cold and strain that may lead to discomfort. According to the traditional concept, you should not go out within 30 days after delivery. The reason is that the immunity of the mother is poor after delivery and has not yet recovered to a normal state, so getting cold or overworking when going out can affect recovery and cause puerperal infection, mastitis, pelvic inflammatory disease and many other diseases. If the pelvic floor muscles are stretched when going out, it may also affect the recovery of the pelvic floor tissue tension, and uterine prolapse may occur. As the living conditions nowadays have improved a lot compared to the past, when the mother’s dew is basically clean by 20 days, she can go out for appropriate activities as long as she keeps warm and does not overexert herself, but she should move around as close as possible, not too far, and rest in time when she feels tired. In addition, it should be noted that if you are in a flu-prone season, you should try to go out as little as possible, and when you must go out, you should wear a good mask to strengthen your own protection. In addition, the mother should pay attention to avoid absolute bed rest, appropriate activity is conducive to recovery, daily walks outdoors in contact with sunlight is also conducive to calcium supplementation, daily diet is mainly light food, more food rich in protein and vitamins, such as eggs, milk, soy products and fresh vegetables, fruits, in order to strengthen nutrition and promote recovery.
