Everything starts in the nose!
Despite decades of study and technological advancement, some aspects of the human body continue to elude medical professionals. This is not at all surprising given how intricate our bodies are.
A recent study found that humans can also sense when death is near because some of us have what is known as a sixth sense and can foretell things in advance. According to scientists, the corpse starts to decompose right away when a person passes away. Decomposition causes a foul and toxic smell known as putrescine to be produced at this time. Evidently, this putrid smell is subconsciously recognized by people. Additionally, when the smell is emitted, a reaction happens right away.
Researchers Ilan Shira and Arnaud Wisman from the Department of Behavioral Sciences at Arkansas Tech University in Russellville, AK, and the University of Kent’s School of Psychology in Canterbury, UK, claim that people can detect odours and respond appropriately, just like animals. That is ultimately a component of species-wide survival.
When individuals are exposed to the smell of putrescine, they react to it both consciously and unconsciously.
These two researchers’ investigations have shown that when individuals are exposed to the smell of putrescine, they flee, exactly like animals do when they perceive danger by either fleeing or engaging in combat.
According to Wisman and Shira, “We do not know why we like (or dislike) someone’s smell, and we’re typically unaware of how scent influences our emotions, preferences, and attitudes.”
Other researchers assert that “it is hard to think of a scent as frightening.” Smells do, however, make people more aware of their surroundings.
Another illustration of how fragrance affects humans is the concept of sex pheromones, which are odors produced by either males or females and that trigger one or more behavioral responses in the opposite sex, bringing the males and females together for the purpose of mating.
“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 sexual pheromones,” researchers said. The researchers also point out that humans are unaware of the smell and do not consciously link it to fear or death.
