The phrase "squatting and defecating is healthier" comes from a group of pictures on the Internet, saying that sitting and defecating will lead to constipation, and squatting posture is a healthy defecation posture. The basis of this statement is that compared with sitting posture, squatting posture can completely relax puborectalis muscle, defecation is not only easier but also more thorough, which can reduce the occurrence of constipation. But the fact is that squatting defecation is indeed more labor-saving and smoother, but sitting defecation will not lead to constipation. There is no difference between the two.

When squatting for defecation, the anorectal angle formed by rectal muscle and rectum is the largest, and when rectum is straightest, defecation is smoother. The anorectal angle is 80 ~ 90 when sitting, and it can reach 100 ~ 1 10 when squatting. In addition, high abdominal pressure during squatting can promote defecation. When sitting and defecating, although the anorectal angle is small, whether constipation occurs has nothing to do with the angle.

Some people think that people squat and defecate with less force, and patients with cardiovascular and cerebrovascular diseases can adopt squatting posture. However, most people with cardiovascular and cerebrovascular diseases are elderly people. When they squat, their legs and knees are under great stress, and they are prone to slip and fracture. When they sit and defecate, they will suddenly have cardiovascular and cerebrovascular diseases because of overexertion. So for them, squatting posture and sitting posture have certain risks.

Squatting defecation and sitting defecation have their own advantages and disadvantages, and we can't say which posture is healthier. We can choose the right posture according to our own situation.
