When we stand, the large intestine (where waste is stored) is pressed against the puborectalis muscle, which maintains stool continence until it’s time to reach the toilet. Sitting only partially relaxes this muscle. Squatting relaxes it completely, essentially straightening the large intestine. This facilitates the disposal process.
Experts have argued that digestive diseases like colitis, constipation, and hemorrhoids have their roots in people who sit and strain on the toilet. Studies have shown, for example, that the more time you spend on the toilet, the more likely you are to develop hemorrhoids, which are swelling of the blood vessels in and around the anus. Some doctors even recommend that patients try squats to manage their colon problems.
Turkish-style toilets are used in many parts of the world today. In Asia, public restrooms consist of two Western-style toilets and two Turkish-style toilets, where the user places their feet over an opening in the floor and squats. Turkish-style toilets can be found in France, Japan, and Russia.
Although Sheth doesn’t currently advise his patients to squat, “I probably should,” he says. “I think there hasn’t been a safe way to do it until now.”
Sheth was referring to the Squatty Potty , a product introduced a few years ago that resembles a footstool. Users rest their feet on it while sitting on the toilet, allowing for a 35-degree knee bend.
