Sihaiwang: with the progress of science and technology, the improvement of living standards. The tools people use are also advancing with the times, and more suitable for the development of human physiological needs. But the fight between squatting and sitting has never stopped, and people are more and more pursuing the smooth squatting. In fact, squatting has its own advantages and disadvantages. It's better to follow the habit and find the most comfortable posture.
Squatting: easier to defecate in theory
The theory that squatting is better than sitting is based on a muscle called puborectalis. Zhu Gang, chief physician of anorectal surgery of Beijing Huimin hospital and vice chairman of Beijing Commission of Integrative Traditional Chinese and Western Medicine on colorectal and anal diseases, said that this muscle starts from one side of the pubic bone, makes a circle around the back of the rectum, and then returns to the other side of the pubic bone, forming a ring, just holding the rectal hook, so that the rectum forms a point forward angle, which is called "anorectal angle", Short for 'right angle of anus'. Generally speaking, the right angle of the anus in sitting position is about 80-deg; ~ 90-deg.; while in squatting position, the right angle of the anus can reach about 100-deg. Theoretically, the greater the right angle of the anus, the less effort it takes to defecate, so the squat is smoother. In addition, when squatting, the pressure on the abdomen is greater than when sitting, which can reduce the abdominal force and help the defecation smooth.
But in addition to the differences in physical structure, we should also consider the differences in culture and living habits. Do you know that there is a word called "Asian squat", that is, our squatting posture. When squatting, the sole of our feet should be on the ground, and the heel is not off the ground. According to the survey, 100% of Asians can do this posture, while only 13.5% of Americans can do it, while 9% of 13.5% are Asian Americans, and the rest are yogis. In a January 2015 report on Chinese toilets, the daily mail of the UK argued that Chinese toilets need a revolution, mainly to 'eliminate squatting'.
For westerners, squatting is not so beautiful, but for us Chinese, squatting has a longer history and a more market. In ancient China's agricultural society, squatting toilets used by the public could not only meet the physiological needs of a large number of people at a low cost, but also collect excrement as fertilizer. Therefore, until the founding of new China and the period of collective economy, squatting toilets were widely used in China. After the reform and opening up, the foreign toilet has entered many families, but with the improvement of people's health knowledge level, there are many concerns about the health hazards brought by the toilet. When the toilet appears in public, it is easy to spread various skin diseases when sitting. According to an online poll, 88% of Chinese believe that the toilets in scenic spots should use squatting instead of sitting.
Defecation: reduce leg pressure
Although squatting is theoretically easier to defecate, sitting does not directly cause anorectal disease. "Sitting is the choice under the trend of social development. As long as the habit is gradually formed, sitting is also an ideal way to defecate. 'Zhu Gang said that it's really more comfortable to sit, with less pressure on the legs and no leg numbness after a long time. At the same time, incidence rate of hemorrhoids is not impossible. Compared with squatting posture, the downward gravity effect of sitting stool abdomen is not obvious, the emptying time is longer, the abdominal force is more, and it is more time-consuming.
Although squatting is theoretically helpful for defecation, it is not necessarily advantageous for some elderly people, especially those with cardiovascular and cerebrovascular diseases. Because squat when abdominal pressure increases, coupled with defecation more force, prone to cardiovascular accidents. Old people are weak in physical strength and squat for a long time. If they stand up quickly, they are also prone to induce transient cerebral ischemia caused by changing body position, which will lead to dizziness, fall of eyesight, fracture and other accidents.
Defecation: Remember '16 word secret'
It's more personal habit to defecate in which posture. It's hard to say which posture is healthier. No matter sitting or squatting, Zhu Gang put forward a 16 character secret to prevent anorectal disease, that is, fixed time, quick battle, concentration and follow-up. It's better not to have any 'selfish thoughts' when going to the toilet, just use these 3-5 minutes to solve this problem, and adjust the thinking consciousness, nervous system and physiological function to the same state, so as to train your own physiological feedback and facilitate defecation. Do not go to the toilet for more than 5 minutes each time, or continuous compression and congestion will easily cause anorectal diseases such as hemorrhoids. It's hard for some old people to solve it in five minutes,
