OK, internet.
-
You asked, so now we're answering.
-
Pooping.
-
It's a thing people do all the time – normally somewhere between three times a day and once every three days.
-
And you may have heard that you've been doing it wrong: you're supposed to squat, not sit!
-
Or so they say.
-
It's probably true that squatting can help make bowel movements slightly easier.
-
But, despite what some people claim, changing your position won't solve all your digestive problems.
-
Humans spent thousands of years squatting to defecate –
-
it's only in the last few hundred years that people in Western countries have adopted the raised toilet, and started sitting instead.
-
So this whole poop-position controversy is based on the idea that squatting must arrange your anatomy in a helpful way, because that's what our bodies evolved to do.
-
On its way out of you, solid waste has to pass through your rectum, and then your anal canal.
-
There's a muscle, called the puborectalis muscle, that loops around your digestive tract between those two sections, and it helps keep poop inside you when you aren't trying to eliminate it.
-
Basically, it makes an angle between your rectum and anal canal, which puts upward pressure on your rectum and holds everything in.
-
And when the muscle relaxes, your rectum and anal canal straighten out a bit, which – along with other muscles that relax and contract – lets stuff … slide out.
-
It's probably not surprising that there hasn't been too much research on the anatomy involved in pooping.
-
But a few small studies say that squatting helps align your rectum and anal canal better than sitting does.
-
A couple others have shown that when people squat instead of sit, they have to strain less and the elimination process takes less time.
-
Again, these studies were small.
-
One used 28 volunteers, and another used only 6.
-
So, it's enough to suggest that there might be something to these ideas, but bigger, more carefully controlled studies need to be done before this can be considered scientific fact.
-
But!
-
If squatting does make things easier, it's possible that it also helps with hemorrhoids.
-
Hemorrhoids are swollen veins near the anus and rectum, which can be painful and lead to itching and bleeding.
-
They're often caused by too much straining when you poop.
-
So if squatting does help with straining, it could make hemorrhoids less likely – but that's basically all we know about the potential benefits.
-
There are companies out there that sell stools to help you pass your…stool, and sometimes they make really exaggerated claims.
-
For example, squatting will fix irritable bowel syndrome or even prevent colorectal cancer.
-
There's just no evidence to support those claims.
-
Gastrointestinal experts seem to agree that if your bowel movements are normal, there's no real reason to squat when you go.
-
There's probably no harm in it, either, but if you're happy with the way you've been pooping until now, there's no need to change up your methods.
