Vani Hari's excellent plane trip [View all]

[Dr. Strange]

So apparently the Food Babe decided to dispense her wisdom regarding the horrors of flying in planes. Among her (non-GMO no doubt) nuggets:

Additionally, the pressurized cabin reduces the humidity by 40% of what humans typically thrive at. The Sahara Desert has more humidity at ~25% than your airplane does at ~10%. Remember your body is made up of 50% water, if the humidity is reduced by 40%, your body becomes very dehydrated, very quickly and usually without you feeling the effects until after you get off the plane. Dehydration causes all sorts of issues from fatigue, headaches, constipation, light headedness and even death in extreme cases.

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.
