This is the same response around fight-or-flight reaction.

When animals sense they are in real danger, there are only two responses: fight the threat or run away from it. The study revealed people react the same.

THERE ARE OTHER SCENTS HUMANS RESPOND TO AS WELL LIKE SWEAT.

Separate studies have shown that sweat taken from people in fearful situations and exposed for others to smell generated an automatic and startled reflex.

“We do not know why we like (or dislike) someone’s smell, and we’re usually not aware of how scent influences our emotions, preferences, and attitudes,” explain Wisman and Shira.

“It is hard to think of a scent as frightening,” say other two leading researchers. These scents make people more aware and vigilant of their surroundings.

HUMANS’ NATURAL REACTION TO DANGER IS NOT TO FACE IT AND FIGHT.

People tend to avoid any type of confrontation, whether its verbal or physical. For the most part, folks choose to distance themselves until fight is the only option left.

THE RESPONSES MAY BE DIFFERENT FROM EACH OTHER BUT PUTRESCINE AND $EX PHEROMONE ARE BASED ON SCENT.

S+ex pheromones are chemicals released by the body to attract a mate while putrescine works as a warning signal. “Putrescine signals a different type of message than pheromones, but people’s responses to putrescine (avoidance and hostility) do seem indeed to be the opposite of responses to many se+x.ual pheromones,” explain the research duo.

During the study, people were not aware they had a negative reaction to the scent.

“People are not familiar with putrsescine and do not consciously associate it with death or fear,” admits Wisman and Shira.
