Not only does everybody poop—but everybody poops in the same amount of time, apparently. Yep, there’s a study for this: Research reveals that all mammals take 12 seconds to poop. (And that includes you.)
Indeed, Study Finds reports, researchers at Georgia Tech have found that—although an elephant’s rectum, at 40 centimeters long (about 16 inches), is ten times the length of a cat’s—they both “do their business” in 12 seconds flat.
And the key to this productivity? Mucus.
The slimy substance covers the lining of the large intestine, the team discovered, and in larger animals they found there’s a much thicker layer of mucus to help move the feces through the body than in smaller animals. So while it still winds up taking larger animals 12 seconds to complete the process (and even though animals use the same amount of pressure to squeeze), their excrement is actually moving faster.
The researchers say this is important because it’s entirely possible that without this newly-discovered mucus lining, pooping might not be possible.
“Talking about, let alone studying, defecation is taboo. But that’s to the detriment of our society because we don’t have a good physical understanding of digestion or defecation,” one of the study’s co-authors, Dr. David Hu, associate professor of Mechanical Engineering and Biology, and adjunct associate professor of Physics, points out in a statement, adding, “As clinicians, I think we underappreciate the role of mucus within the intestinal tract. We know it’s there, but few studies have paid much attention to it. This study demonstrates a physical, and mathematical, reason why it’s there.”
Hu says the mucus discovery could be quite beneficial in studying and better understanding related illnesses.
“If mucus plays a role in normal physiology of defecation, which this study shows, then abnormalities in mucus may play a role in abnormal physiology. This possibility is intriguing and could expand our current understanding of how gastrointestinal disorders, like constipation or infectious colitis, may occur,” he says.
“If we think that mucus is playing a role, then could we develop new treatment strategies based on medications, including enemas or oral agents, that more closely resemble mucus? These possibilities would be novel,” he says.
The study has been published in the journal Soft Matter.
