科學(xué)家說，這么多年你用衛(wèi)生間的方法可能都是錯的，你的方法很容易造成各種健康隱患。真的嗎？那么正確的用法是什么？

Theres an emerging school of thought that claims our traditional way of defecating — sitting on a toilet with our knees at a 90-degree angle — is leading to increased instances of constipation and hemorrhoids.

So can changing your pooping position make a difference？ According to a study published in Digestive Diseases and Sciences， it just might. The studys participants pooped in one of three positions： sitting on a toilet at a standard 16 inches （41 centimeters） high， a toilet 12 inches （31 centimeters） high or squatting over a container. The subjects were asked to record their efforts， including how long it took to poop and how much effort it took to successfully poop. The several dozen participants revealed some intriguing results. The squatting poopers got the job done faster， going in 51 seconds compared to 130 seconds for their high-seated counterparts. Whats more， those who pooped in a squatting position rated their experiences as easier .

The idea is that when we squat to poop， the colon will straighten， which makes it easier and faster to evacuate its contents from the body. The result could be a more thorough elimination of feces.

It may seem like a strange concept in the U.S.， but squatting to poop is commonplace in other parts of the world. As many as 1.2 billion people dont have access to any sort of toilet， while people in many parts of Asia， for example， avail themselves of toilets designed exclusively for squatting.
