Clothing can restrict blood flow
Poop, in simplest terms, is your body’s natural way of expelling waste and toxins, which are the usable nutrients from food. Pooping digested waste involves many aspects of your body including blood flow, according to Dr. Josh Axe. Tight clothing, particularly shapewear from Spanx and CrossFit compression tops squish, squeeze and sculpt the body, suggests the LA Times. But when it comes to your bathroom breaks, wearing tight tops that restrict the abdomen, or pants around the legs, could restrict blood flow. And that means a less than optimal poop.
