Why Do We Get ‘The Runs’ on Airplanes?

We get the runs on airplanes because things change suddenly and our bodies don’t like that.

Airplanes are like a big, fast car, but they’re also kind of like a sealed bubble. When you're in the bubble, everything is cozy, until it’s not.

On an airplane, the air pressure gets lower than what we're used to on the ground. This makes your ears pop, and sometimes your stomach feels funny too.

Think of it like opening a soda bottle, when you pop the cap off, fizz comes out fast. Your body is like that soda, when the pressure changes quickly, everything inside can get all mixed up.

Airplane food is also part of the problem. It’s often dry, salty, and not very exciting. That makes your stomach work harder to digest it, especially if you've been sitting still for a long time.

So, when everything comes together, pressure changes and boring food, your body decides, “I’m going to do something about this!” and that’s when the runs happen. It's like your stomach is saying, “I need to shake things up!”
