It so happened historically that man, like some other species of mammals,learned to squat to rest, do something or go to the toilet. But how much does the modern toilet bowl satisfy the physiological needs of man?
Toilet bowl: a luxury item
Since Sir John Harrington invented the toilet, and it was in 1591, our view of the defecation process has changed.
At first, the toilet was considered a luxury item, as it was only available to royal people and nobility. In exceptional cases, people with physical disabilities could use the toilet.
As the plumbing industry progressed, the toilet bowls began to be mass produced.This made it possible to provide people with a "privilege", previously available only to the rich. Then a hike habitin the toilet"Squatting" has changed, and with it the pose and the physiological process itself.
Better "squatting the scientific opinion
Dr. Henry L. Boccus in his book Gastroenterology of the year 1964 concluded that for ideal defecation it is necessary to crouch so thatThe hips were pressed to the stomach.
Similarly, in 1966, Dr. Alexander Kira, in his book "The Bathroom argued that human nature expects to cope with its needs on the haunches, sincethis reduces effort during bowel movement..
In addition, in 2003, Dr. Dov Sikirov published a study comparing forces used during defecation while sitting on the toilet, and those that were attached in the "squatting" position.
The results showed that in the latter case, a person experienced a satisfying feeling of bowel movement. In the positionsitting on the toilet, the process of defecation requires excessive tensionand more time in comparison with the position of "squatting".
What happens during bowel movements?
The term "defecation" means the process of emptying the intestine,disposal of the body from digestive products.
During this "journey" the enteral nervous and parasympathetic systems make it possible to carry out various actions, such as control of the accumulation of fecal matter in the large intestine, as well as relaxation of the external sphincter and muscle tissues..
This action allows rectifying the intestine and displacing the waste by means of intra-abdominal pressure.
It should be noted thatin a squatting position, the legs of a person are at an angle of 35º with respect to the trunk.So the hips are pressed to the stomach.
In this position, pressure occurs inside the cavity of the colon, the rectum is aligned with the anal canal and intestinal masses are eliminated. This leads to faster, easier and full bowel movements.
Sitting on the toilet
In the sitting position on the toilet, the opposite occurs.The angle between the legs and the trunk (abdomen) is already 90º, because of which the rectum and anus are not on the same "line it is not aligned.
Besides,The pressure that the legs placed on the abdomen is also "lost".As a result, to go to the toilet, the person has to push harder. This posture during defecation causes various diseases, for example such as constipation, irritable bowel syndrome, hernia, hemorrhoids and, in more severe cases, colon or intestinal cancer.
Advantages of the "squatting" posture during defecation
- Allows to make the process of bowel evacuation more rapid and easy.
- Prevents leakage of feces between the colon and small intestine, which reduces the likelihood of infection of the latter.
- It helps to avoid strong stresses and thus prevent a hernia, diverticulosis and some other diseases.
- May be part of a non-invasive treatment in case of an exacerbation of hemorrhoids.
- Pregnant women such a position will help to avoid pressure on the uterus. And she actually prepares the body for natural childbirth.
- Complete evacuation of waste prevents stagnation of feces. And this condition, as is known, is one of the most important factors in inflammation of appendicitis and inflammatory bowel disease.
It is also important to mention that this position of the body during defecation (when the angle of the leg-trunk is 90 °) is associated with the possibility of the occurrence of colorectal cancer. However, a study conducted by Sahand Sohrabi shows that this hypothesis is not yet final.
How to fix the situation?
In the field of furniture design, several initiatives have emerged related to the position of the human body during defecation.
But we can easily have at home each of us toilet bowls"Perfect substituting for it... a stool.Its height is not of fundamental importance, the main thing is that such a support helps you to bend more andprovide the required angle of 35º.
Some people decide to lean on the toilet seat to get the right pose (squatting). However, this action may present a certain danger, the toilet can simply fall, and the person, respectively, with him. So the latter option is definitely not recommended.
