The Smell Of Fear Is Real

The smell of fear, one of the most terrible cliches of pulp fiction, is founded in fact, scientists claim. People can unconsciously detect whether someone is stressed or scared by smelling a chemical pheromone released in their sweat, according to researchers who have investigated the underarm secretions of petrified skydivers.

The team found that the smell of fear triggered a heightened response in brain regions associated with fear when inhaled by volunteers in a brain scanner. The research suggests that like many animal species, humans can detect and subconsciously respond to pheromones released by other people.
