The study confirms anecdotal evidence that flying increases flatulence, finding that changes in air pressure at altitude make the gut produce more gas.
The in-depth review of scientific literature on flatulence, led by Danish gastroenterologist Jacob Rosenberg, looks at issues such as whether women's farts smell worse than men's (yes), what causes the odour (sulphur) and how often the average person passes wind every day (10).
The bottom line, according to the 3000-word study published in the New Zealand Medical Journal, is that passengers should ignore the social embarrassment of breaking wind and "just let it go".
Holding back can cause discomfort and pain, bloating, indigestion, heartburn and even stress resulting from the required concentration. The authors said that while passengers may experience poor service from the cabin crew as a result of their decision, the health benefits outweighed any negative impacts.
"We humbly propose that active charcoal should be embedded in the seat cushion, since this material is able to neutralise the odour," they wrote.
We strongly agree. A Flat-d.com pad of any type has helped thousands of airline passengers avoid embarrassment and discomfort of individuals around them. We offer activated charcoal pads that go in your underwear and Chair Pads that you simply put on your seat. Whenever we travel we always have a Flat-D on.
