On average, humans pass gas up to 23 times a day, and although men do it more often, a study found that women’s gas smells worse. Surprisingly, that might actually be a good thing.
In 1998, gastroenterologist Dr. Michael Levitt, unapologetically nicknamed the “king of farts,” fed volunteers beans and laxatives and collected their gas in special bags for analysis. The results were clear: women’s gas was rated as more intense, mainly because it contained higher concentrations of hydrogen sulfide, the compound responsible for the classic rotten-egg smell.
And here comes the unexpected twist.
That same hydrogen sulfide, in controlled doses, has been studied for its potential protective effects on the brain. In 2021, research from Johns Hopkins showed that mice treated with compounds derived from this substance improved their memory and motor skills by up to 50 percent, and even partially reversed cognitive symptoms associated with neurodegenerative diseases.
So next time someone complains about the smell, you can say: “I’m protecting my brain.”
