The daily use of the corset should not exceed 8 hours, and it is generally recommended to use it when getting out of bed for activities, and it can be used without the corset when lying in bed for sleeping or resting. The use of postnatal girdle can reduce the sagging of abdominal organs, promote uterine recovery and prevent postpartum hemorrhage, etc. However, the daily use of girdle should not be too long, so as not to affect the local blood circulation and cause skin allergies and other adverse reactions. In addition, it is not recommended to use the corset immediately after delivery, and it is better to start using it about 42 days after delivery, because the pelvic organs are relatively loose after delivery, and the early use of the corset will increase the pressure in the abdominal cavity, thus aggravating the prolapse of the pelvic organs. In addition, the use of postnatal girdle should not be too tight, in order not to affect the breathing is appropriate, at the same time should choose elastic, breathable girdle.
