Why do airplanes make you gassy?

Melissa and Jam, Bleav
About this episode

#211

Melissa and Jam delve into the chemistry behind increased flatulence on airplanes. They explore how changes in air pressure affect gas expansion in the human body, leading to more frequent gas release during flights. The discussion covers the physiology of high altitude flatus expulsion (HAFE), personal anecdotes, and practical advice for managing this phenomenon. Additionally, they touch on how airplane cabin air is regulated and hint at more topics related to airplane air quality in the next episode.
