Much like a sneeze, a burp is your body’s way of taking care of itself.

A burp is really nothing more than the sound of gas escaping your body. When you drink or eat, you also swallow air.

As you continue to eat or drink and therefore continue to swallow air, the gasses build up in your stomach until your body releases them in the form of a belch or burp.

One of the most common causes of burping is eating too fast. The faster you eat, the more likely you are to swallow extra air. Fizzy carbonated beverages, such as sodas, contain tiny gas bubbles, which also can increase the chances of burping.

Burping in public may be impolite, but did you know it could actually be valuable, too?

Researchers estimate that cows in the United States burp 50 million tons of valuable gasses into the atmosphere each year. If those gasses could be collected, the annual burps of only 10 cows would provide enough energy to heat a small home for an entire year!

Fun facts about burping:

  • In some cultures, burping after a meal is a compliment to the cook.
  • The official medical term for burping is “eructation.”
  • Farm animals produce so much gas that scientists consider them to be a major contributor to the greenhouse effect.
