Netizens often discuss a question: Is it better to squat or sit in the toilet when defecating? Well, that's a problem. Not surprisingly, squatting defecation is more in line with the physiological structure and smoother. Why do you say that?
Because in the evolution of millions of years, human beings have long formed the habit of squatting and defecating, not sitting, not lying down, nor lying down. Squatting defecation not only conforms to the physiological structure, but also responds most quickly. This rapid response includes not only rapid defecation, but also rapid escape. Imagine that when ancient humans defecated in the jungle wilderness where wild animals were infested, suddenly a big cat jumped out of the grass. Which posture do you think is more conducive to our ancestors' escape at this time?
Why is squatting defecation the most enjoyable and smooth? This has a medical basis. There is a U-shaped puborectal muscle near the anus. It starts from one side of the pubic bone, wraps around the rectum, and then connects back to the other side of the pubic bone to form a ring, which just hooks the rectum and makes the rectum form an angle with the tip forward. It's called anorectal angle.
Please imagine yourself that the anorectal angle is about 90 when sitting, and it can reach 1 10 when squatting. Theoretically, the larger the anorectal angle, the more vertical the rectum, and the smoother the defecation. In addition, when people squat, squeezing the abdomen can also promote defecation, which can reduce the stress on the abdomen and alleviate the difficulty of defecation. Therefore, when squatting and defecating, the intensity is small. We just need to hold our breath gently. Hey, it will come out. If it goes well, it will be thousands of miles away. It must be said that defecation force is sometimes fatal, especially for the elderly with cardiovascular and cerebrovascular diseases. If they hold their breath, heart attacks or strokes are not uncommon.
But sitting toilets are very popular now. Isn't there an advantage to sitting toilets?
Not exactly. The advantage of the toilet is very obvious, that is, comfort! Squatting is easier and smoother, but it is more tiring, and not everyone can squat comfortably. Squatting for a long time will lead to backache, leg numbness and varicose veins, especially for the elderly, pregnant women or patients with physical exhaustion. Squatting defecation is easy to cause problems, so such people are more suitable for sitting in the toilet and comfortable. As mentioned above, the disadvantage of sitting stool is that the anorectal angle is relatively small, the rectum is not straight enough, and there is no gravity action such as abdomen downward when sitting, which leads to a long emptying time, more abdominal force and longer time consumption. This may aggravate hemorrhoids and even have the possibility of proctoptosis.
At this time, someone put forward a method that seems to be the best of both worlds: step on a small bench while sitting, and try to simulate the effect of squatting when defecating by reducing the angle of thighs and torso. However, this is actually useless, because the angle of anorectal angle has not changed, so it can not help reduce defecation force.
Whether to squat or sit in the toilet at home, I think it varies from person to person, and everyone can choose a way that is more in line with their own needs. It is best to have both squat toilets and sitting toilets to meet the needs of different people. It is more convenient for the elderly and pregnant women to choose the toilet naturally, while ordinary people may be able to experience the pleasure of traveling thousands of miles a day by squatting in the toilet. Whether squatting or sitting in the toilet, it is most important to develop good defecation habits. For people who have good defecation habits, squatting in the toilet can help them enjoy life, but for people who are often constipated, squatting in the toilet may not necessarily solve the problem.

Eat more foods that are really high in fiber, such as peas-how to treat constipation: 1 spinach, oats, etc. Drink plenty of water, and lack of water in the body will also cause constipation. Drink 1.5~2L of water every day. More exercise and 20~30 minutes' walk can promote gastrointestinal health. Avoiding drinking will make people lack water and aggravate constipation symptoms.
Constipation depends: not everyone needs to defecate once a day! Influenced by diet, intestinal flora and other factors, there are individual differences in defecation. As long as you defecate easily every time and don't feel flatulent or uncomfortable because you defecate too little, not less than 3 times a week, it is not constipation!
