A few facts about what airplanes do to your body -
When your body is in the air, at a seriously high altitude, your body under goes some serious pressure. Just think about it Airplanes thrive in places we don’t. You are traveling in a pressurized cabin, and when your body is pressurized, it gets really compressed!
The air you are breathing on an airplane is recycled from directly outside of your window. That means you are breathing everything that the airplanes gives off and is flying through. The air that is pumped in isn’t pure oxygen either, it’s mixed with nitrogen, sometimes almost at 50%. To pump a greater amount of oxygen in costs money in terms of fuel and the airlines know this! The nitrogen may affect the times and dosages of medications, make you feel bloated and cause your ankles and joints swell.
Did you know certain countries require that airplanes and even passengers be sprayed with pesticide before they take off? This means if you are visiting one of these countries you are breathing in these fumes potentially all flight, especially if they were sprayed on board. Horrific!
