After vaginal delivery or as women age, vaginal laxity can affect the quality of sexual life and increase the chance of gynecological diseases such as stress urinary incontinence. There are several ways to achieve vaginal contraction: 1. You should do anal lift (Kegel exercise), which is to tighten the anus when you inhale deeply, then continue for about 5-10 seconds and exhale deeply to relax the anus, repeat about 50-100 times a day. By doing this exercise, you can exercise and strengthen the pelvic floor muscles, and regular exercise can prevent urine leakage and tighten the vagina.2. Consciously stop urinating for a few seconds before starting to urinate when you urinate, so that you can control the contraction of the vagina.3. Go to a hospital rehabilitation center for bioelectric stimulation training, which gives electrical stimulation in the vagina to promote the contraction of the pelvic floor muscles.
