The Smell of Fear

Did you know humans actually have the ability to smell feelings of fear and disgust through sweat?The findings were recently published in the journal of Psychological Science.

Researchers collected sweat from men as they watched movies that caused these feelings. To remain odor-neutral for the sweat test, the men used scent-free products, and quit smoking and using alcohol. Women participants then completed visual search tests, while unknowingly smelling the sweaty samples. The women’s eye movements and facial expressions were recorded during this time.

The researchers found that women who smelled the “fear sweat” opened their eyes widely in a fearful expression, and women who smelled the “disgust sweat” also displayed facial expressions of disgust.
