How to defecate is more conducive to health?

Squat defecation can really make defecation smoother, but it has no effect on preventing constipation. Sitting and defecating will not increase the risk of hemorrhoids, constipation, colitis, appendicitis, colon cancer and other diseases. In addition, squatting posture can reduce abdominal exertion, which may have certain advantages in preventing cardiovascular and cerebrovascular accidents during defecation, but improving leg sitting posture is completely useless. Myth: Although the popular toilets are luxurious and convenient, they bring various modern diseases such as hemorrhoids, constipation, colitis, appendicitis and colon cancer. People often think that the crux of these problems lies in insufficient dietary fiber intake. In fact, the culprit is really the wrong posture when going to the toilet. When defecating in sitting position, the puborectalis muscle is only partially relaxed, and only when defecating in squatting position, the muscle is completely relaxed, so that defecation is not only easier, but also more thorough. If squatting is inconvenient, you can also step on a small bench to go to the toilet, which can reduce the included angle between thighs and torso and achieve the effect of simulating natural squatting posture. Truth: This is an advertisement for a foreign toilet product. Deleted the content about the product, the original intention may be to tell you the correct and healthy toilet knowledge. However, this infographic is not scientific. Squat pull can really make defecation less hard and reduce defecation time, but sitting pull is not the chief culprit of various anorectal diseases. It is completely cheating to try to simulate squat pull with your feet on a small bench. Squats are really smoother. The theoretical basis that squatting defecation is superior to sitting posture mainly lies in a muscle called puborectalis muscle. This kind of muscle starts from one side of the pubic bone, goes around to the back of the rectum, and then returns to the other side of the pubic bone to form a ring, just pulling the rectal hook, so that the rectum and the tip form an angle forward, which is called anorectal muscle. Is the anorectal angle of sitting posture about 80-90? And the anorectal angle can reach 100 when squatting? About. Theoretically, the greater the anorectal angle, the more labor-saving defecation is. Sitting has nothing to do with getting sick. So it seems that squatting to defecate is better than sitting. Wait, the conclusion that squatting defecation reduces constipation from a larger anorectal angle implies a premise that constipation is caused by a smaller anorectal angle. But in fact, although the larger anorectal angle can make defecation less hard and reduce defecation time, the decisive factor of constipation is not anorectal angle. There are many reasons for constipation, including age. Constipation is more common in the elderly than in the younger generation. However, diseases and drugs are also a very important inducement. Suppress one's will Changes in living habits, such as holidays and outings. Hormones change during pregnancy or menopause. Take certain drugs, including antacids, powerful painkillers (such as morphine) and some antidepressants. Some diseases, such as Parkinson's disease and diabetes. There is no mention of the role of anorectal angle. It should be said that constipation is a pathological state, and it is a feeling of illness before defecation. Squat posture may partially relieve the symptoms of defecation difficulty, but this does not mean that squatting defecation will not cause constipation, or sitting defecation will cause constipation. Just as hot water in the abdomen can relieve dysmenorrhea, it does not mean that dysmenorrhea will occur without hot water in the abdomen during menstruation. People who don't have dysmenorrhea, no matter whether hot water is enough or not, will not have dysmenorrhea. Since small anorectal angle will not cause constipation during defecation, the logical chain of sitting defecation with small anorectal angle+constipation caused by sitting posture = constipation caused by sitting posture will be broken. That is to say, people who are constipated will be constipated regardless of sitting position or squatting position, and people who are not constipated will not be constipated regardless of sitting position or squatting position, but squatting position may make people who are constipated more relaxed. Other anorectal diseases mentioned in mythology, such as hemorrhoids, colitis, appendicitis and colon cancer, are similar, and the different anorectal angles of squatting posture and sitting posture are not the reasons for these diseases. Of course, this does not mean that squatting and defecating are useless for preventing diseases. The advantage of squatting defecation is that the strength is small and the defecator consciously empties for a short time. For people with high risk of coronary heart disease and stroke, defecation force is an important cause of cardiovascular and cerebrovascular accidents. Usually, for people with high risk of myocardial infarction or stroke, doctors will use some laxatives to reduce the force of defecation to reduce the risk. Squatting can reduce the exertion of defecation, which is theoretically beneficial to prevent accidents during defecation. The high-risk groups of cardiovascular and cerebrovascular accidents are mostly middle-aged and elderly, and their physical strength is relatively weak. However, when squatting, the stress on the legs and knees is relatively large, which is prone to accidents such as slipping and fracture. Therefore, for them, squatting posture may not have great advantages over sitting posture. Step on the bench? It is suggested to step on a small bench with your feet to reduce the angle of thighs and torso and simulate the effect of squatting and defecating. Does this work? Unfortunately, the answer is no, some scientists have studied the normal sitting posture (thighs and torso are 90? ), raise the sitting posture of the legs (the thighs and torso are 60? ) and squatting posture, it is found that the anorectal angle of squatting posture is obviously larger than that of sitting posture, but there is no difference between the two sitting postures. Another study thinks that the emptying time and abdominal force of squatting defecation are less than that of sitting posture, but there is no difference between sitting posture and leg lifting posture. Therefore, although stepping on a small bench can narrow the angle between the thigh and the trunk, it is not helpful to straighten the anorectal angle, and it is naturally useless to help reduce the pressure of defecation. Anorectal angle in three defecation postures. The anorectal angle of squatting posture is the largest, while that of normal sitting posture (thigh and trunk are 90? ) and sitting posture with legs raised (thighs and torso at 60? The anorectal angle is basically the same. Conclusion: The rumor is shattered. Squat defecation can really make defecation smoother, but it has no effect on preventing constipation. Sitting and defecating will not increase the risk of hemorrhoids, constipation, colitis, appendicitis, colon cancer and other diseases. In addition, squatting posture can reduce abdominal exertion, which may have certain advantages in preventing cardiovascular and cerebrovascular accidents during defecation, but improving leg sitting posture is completely useless.
