Your skin has smell receptors that help it heal

By Carolanne Wright

Smell is one of the most ancient human faculties — it has also been the least understood by science until recently. Biologists first uncovered the inner workings of chemical sensors in our noses, otherwise known as olfactory receptors, in the early 1990s, a finding that led to a Nobel Prize.

But the story doesn’t end there. Over the last decade, scientists have discovered that smell receptors are not only found in the nose, but also throughout the body — in the brain, colon, heart, liver, kidneys, spine, prostate and even sperm — and play a crucial role in a range of physiological functions. And now, a team of researchers at Ruhr University Bochum in Germany have confirmed even our skin is covered with these receptors.

“More than 15 of the olfactory receptors that exist in the nose are also found in human skin cells,” said lead researcher, Dr. Hanns Hatt. What’s more, exposing the skin receptors to specific odors triggers a cascade of reactions that prompt healing of injured tissue.
