A squat toilet also known as a squatting toilet is a toilet used by squatting rather than sitting. There are several types of squat toilets, but they all consist essentially of toilet pan or bowl at floor level. See the health benefits of using squat toilets;
In the squatting position, gravity does most of the work. The weight of the torso presses against the thighs and naturally compresses the colon. Gentle pressure from the diaphragm supplements the force of gravity.
Squatting relaxes the puborectalis muscle, allowing the anorectal angle to straighten and the bowel to empty completely.
Squatting lifts the sigmoid colon to unlock the "kink" at the entrance to the rectum. This kink also helps prevent incontinence, by taking some of the pressure off the puborectalis muscle.
The colon is equipped with an inlet valve (the ileocecal valve) and an outlet valve (the puborectalis muscle). Squatting simultaneously closes the inlet valve, to keep the small intestine clean, and opens the outlet valve, to allow wastes to pass freely. The sitting position defeats the purpose of both valves, making elimination difficult and incomplete, and soiling the small intestine
