There is no clear clinical definition of how long after a normal delivery one can do Kegel exercises, generally after 42 days, when the uterus recovers better, one can do Kegel exercises. Kegel exercise can enhance the muscle tone of the pelvic floor muscles by repeatedly scaling part of the pelvic floor muscles, which is conducive to the recovery of the pelvic floor muscle tissues and reduces the condition of vaginal laxity. Kegel exercises can avoid postpartum urinary incontinence in pregnant women and can effectively prevent uterine prolapse. In general, the uterus has basically recovered 42 days after delivery, and it is more appropriate to do Kegel exercises at this time. Doing Kegel exercise too early may reduce the discharge of bad dew, resulting in poor uterine recovery or inflammation. It is recommended to do Kegel exercises under the guidance of a doctor and not too early to avoid damage to the body.
