Find out why smelling your own farts can be beneficial.
Enjoy!
Before we start, you should know that this is not a joke. According to the scientists from the University of Exeter, smelling farts in fact prevents cancer, among other diseases.
When the bacteria break down food, they produce a gas, known as hydrogen sulfide. Even though this gas is known to be pungent, foul-smelling gas in rotten eggs and flatulence, it is naturally produced in the body and it even might be considered to be a healthcare hero with considerable implications for future therapies for a variety of diseases, says Dr. Mark Wood in a university release.
Even though harmful in large doses, a whiff here and there of this stinky gas can reduce risks of cancer, heart attacks, strokes, dementia, and arthritis. As the scientists explain, this is due to the preserving of mitochondria.
The researchers are even rising with their own compound to imitate the health benefits of the smell.
According to Professor Matt Whiteman of the University of Exeter Medical School, they have made use of this natural process by making a compound, called AP39, which slowly delivers very small amounts of this gas specifically to the mitochondria. Their results have shown that if stressed cells are treated with AP30, mitochondria are protected and the cells stay alive.
So, next time you catch a whiff do not get distressed or mad, but be thankful instead.
SciShow host Michael Aranda explains why humans and some species of animal sneeze.
Enjoy!
Why do we sneeze? The long-standing answer has been that sneezing is a reflex. When irritants — such as germs, dust, pollen, animal dander, or pollutants, just to name just a few — infiltrate the nose lining, the brain sends out a signal to get rid of it. That triggers a deep breath, which gets held in the lungs. As a result, the chest muscles tighten and pressure builds. The tongue pushes against the roof of the mouth, forcing breath to come out fast through the nose — Achoo!
