Humans can smell fear, detecting molecules in sweat odour which indicate another person is afraid, according to German psychologists.
Previously it was thought that only animals such as fish, flies and rodents had such a faculty.
But the detection in humans is unconscious.
“We are the first in the world to prove that emotions can be communicated chemically between humans,” said Bettina Pause, a psychology professor at the University of Dusseldorf who led the study.
They team showed that when a person smells “fear” molecules from somebody else’s skin, this stimulates regions of the brain responsible for empathy and interpreting other people’s emotions.
Pause said humans know someone else is afraid wit
