Anal retractions usually do not cause significant harmful effects on the body, but excessive retractions may cause dysfunction of the anal sphincter.
When excessive anal contraction exercise leads to dysfunction of the anal sphincter, it will cause the body to have defecation dysfunction, and may also cause obstructive constipation, but the probability of this is very low, so the anal contraction exercise is usually a very safe exercise within the moderate range.
Anal retraction exercise is a kind of health care exercise for the anal area, which can enhance the tension of the anal sphincter, relieve the anxiousness and heaviness (discomfort in the lower abdomen, wanting to defecate very much, and having a feeling of incomplete defecation after defecation) and so on, and at the same time, it can also improve the local blood circulation and alleviate the local pain, and so on.
It is recommended to perform anal retraction exercise appropriately.
