Excess gases during flights? Calm down, which science explains!

If you often take flights, whether for business or pleasure, you may have been through this situation which, although it seems, is not as peculiar as you might think: flatulence during the flight. This is not impolite or careless about the colleague in the next seat and science can explain the reasons for the escapade.

According to professors at the University of Copenhagen, Denmark, flatulence during flights is not only quite common but also natural. They explain that the higher the altitude, the more intestinal gases are produced by our body.

Scientists who have devoted themselves to studying the causes of flatulence in the sky have concluded that it is all a "simple" matter of physics. The increase in gas production occurs at high altitudes because when the pressure decreases, the gas takes up more space, increasing in volume.

In addition to Professor Jacob Rosenberg, five other researchers dedicated themselves to explaining the reasons for swollen bellies and flatulence released in mid-flight. "The pressure drops and the air must expand in a larger space, " he explained in an interview with the BBC . The professor estimates that one liter of gas occupies 30% more volume during a plane trip. In addition, the researchers calculated that an average adult can expel about 10 flatulences daily.

Although it sounds silly or whimsical, flatulence in flight can be dangerous to the health of older people, Rosenberg explains. "If you're young and healthy, it's not a problem, but for older people it can be a risky endeavor for the heart, " he said.

Researchers also warn that retaining flatulence for a long time - remember 18-hour flights - can cause more than discomfort. Symptoms of this retention include pain, swelling, dyspepsia (discomfort in the upper abdomen) and heartburn.

Scholars have even given tips to ease the discomfort: use pillows and walk during the flight to prevent gas buildup. The study was published in the New Zealand Medical Journal .
