The Science Behind Easystool

A large percentage of us on Earth are still squatting to defecate, by placing your feet on the easystool you are assuming the natural human toilet posture while sitting on your own Loo.

So this squatting posture to go is nothing new, but what’s the science behind squatting?

When you use the easystool and put your knees up to go you change the relative angle between the pelvis and the knees (the anorectal angle), in effect squatting.

This squatting posture to defecate simultaneously closes the ileocecal valve, pressurising the colon to defecate and relaxes the outlet valve (puborectalis muscle) unkinking the Colon and so with little effort and gravity allows the waste to pass freely.

Sitting on the toilet with our legs at 90 degrees, doesn’t fully close the ileocecal valve and constricts the outlet valve (puborectalis muscle) from being fully open, kinking it and therefore more force is needed by straining to eliminate.

If you are suffering from constipation or haemorrhoids or Pelvic floor issues, the easystool and a small modification in behaviour can alleviate you ailments.

Even if you have no issues, doesn’t it make sense to go as nature intended….with your knees up!

Disclaimer; the easystool is a toilet stool designed for easier and fuller elimination and makes no claims in cures of digestive diseases, always consult medical professionals.


Below are studies conducted by Medical researchers and statistics and other facts I have compiled to support the argument that we should all be doing it with your knees up.

Influence of Body position on defecation in humans

This Japanese study in 2010 compared three positions on human defecation and measured the anorectal angle and abdominal pressure simultaneously.

They found that squatting straightened the anorectal angle and there was less force required to defecate.

The conclusion is less straining is required to defecate in a squatting position.

Comparisons of straining during defecation in three different positions

In 2003, Israeli Dr Sikirov compared 28 people in sitting or squatting postures and studied the time it took for their bowel movements and their impressions in each posture.

Conclusion; More effort was required to defecate in the sitting position compared to the squatting position.

Globocan 2012. Colo-rectal cancer incidence by countries

The World Health Organisation.

International Agency for research on Cancer has the Globocan 2012 project which collates statistics on Colon cancer.

This link shows a simple map that demonstrates that per capita the rates of Colon cancer by countries. Click on site in the bars and chose Colorectal. Notice the countries that use a squatting posture to poop have lower rates of Colon cancer.

Squatting for the prevention of Haemorrhoids?

An interesting article by the University of Wollongong professor Brian Martin and his associates. Christine Dimmer, Nolene Reeves and Frances Sullivan. October 1996.

They discuss the proposal that squatting to go can alleviate piles.

That many social barriers exist and design technology is lacking for squatting. (Of which we at easystool have solved!)

Also the medical communities focus on research for treatments after the fact rather than prevention, focus on high tech solutions rather than low tech behavioural solutions and social factors of taboo in discussing toilet habits and health.
