Leakage of urine when sneezing is considered mild, leakage of urine when walking fast is considered moderate, and leakage of urine when changing any posture, such as when standing, is considered severe stress incontinence. In fact, pelvic floor muscle problems do not only happen to postpartum mothers. According to a survey by the Women’s Health Coalition (WHC), 1 in 5 women over the age of 25 suffers from urinary incontinence, regardless of whether they have given birth or not. Women who have not given birth are also inevitably plagued by pelvic floor muscle problems. Therefore, no matter what age you are, whether you have been pregnant or not, it is important to pay attention to the daily maintenance and recovery of your pelvic floor muscles.
