There is one thing in life that every human being will go through, and that is experiencing death. Despite the universality of the experience, there is still a lot of mystery surrounding it.

Humans do not like to be in the dark about things, and perhaps that is why the idea of death scares so many people. However, research shows that while death remains largely a mystery, some of the things surrounding it are becoming more and more obvious.

What cannot be explained by science is often referred to as a ‘sixth sense’ by people. And sometimes, scientific research comes out which ends up confirming what humans had long suspected with their sixth sense.

According to research, when a person dies, their body immediately starts to break down. During this, putrescine is emitted into the surroundings. Putrescine is a toxic and foul smell, and humans, at a subconscious level, can recognize this as a putrefying odor. And when the human brain recognizes this scent, it immediately responds to the death.

Researcher Arnaud Wisman from the University of Kent’s School of Psychology in Canterbury, UK, and Ilan Shira from the Department of Behavioral Sciences in Arkansas’ Tech University in Russellville, Arkansas, shared that much like animals, humans can also sense scents and respond accordingly. This is a major survival tactic developed across several species. So when humans come across putrescine, consciously or subconsciously, they respond to it.

The researchers conducted experiments that show that when humans are exposed to the putrescine scent, they move away similarly to animals who also run away in similar circumstances. “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,” Wisman and Shira stated.

“It is hard to think of a scent as frightening,” other researchers have claimed. But it is not untrue that scents make people more alert about their surroundings.

Sex pheromones, which are defined as odors produced by males or females, also have a reaction on human behavior, which usually brings a reaction in another human 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,” one researcher explained.

But unlike other scents, for this one, humans are not aware they are smelling it and their response is more likely subconscious. So it seems our nose can help us figure out if there is death or perhaps ‘danger’ nearby.

It is always so fascinating to learn about how humans work and how our subconscious might be reacting to things we might not even notice! Share this with others so they can also know about this fascinating discovery.
