Your nose is the first indicator that death is approaching

It is human nature to believe in death in our minds, and the way death is depicted is associated with a dead animal, human, bird or fly. So, what’s the connection between all of this, but haven’t we covered it before? Smell.

According to current research, the human nose is capable of sensing a variety of odors, and cannot classify them in any particular category, but reacts to them. Such as the odor produced by a chemical known as putrescine. It’s a chemical that the body releases when it begins to decompose, and one small thing to be aware of is that odors are the result of necrotic behaviors in animals throughout the years of evolution, and these responses are thought to have evolved at least 420 years ago. million years ago.

Animals are thought to respond to the smell of putrescine as a sense of danger in two different ways: a response to the presence of a predator, and secondly, an instinct telling them to flee because their lives are in danger. .

To prove that human reactions and behavior are not different from these animals, scientists conducted 4 types of experiments on humans with a mixture of patrescine, water and ammonia.

Vigilance

Experiment 1 tested participants’ vigilance by exposing them to the smell of humus after testing it. The results showed that participants exposed to the smell of humus were significantly more alert than those exposed to ammonia or water.

Escape behavior

In a second experiment, the scientists tested a group of unsuspecting people who were offered a task to rate odors, namely intensity, disgust, and familiarity. The researchers wanted to see how the participants reacted to the smell and how fast the participants could walk 80 meters. Those exposed to the smell of teeth tended to move away from the area more quickly, suggesting that odors can be a powerful escape motivator.

In a further experiment, shortly after the group was exposed to the scent of patrescine, the researchers tasked the participants with completing the stem.

The results showed that the smell of humus was brought into the group by combining escape and other word stems related to escape words. Smell has also been added to the use of string words.

Defense and hostility

In the final experiment, participants were exposed to a pleasant odor that they did not find. In this experiment, they were offered a text to study, and the task was to evaluate its author.

Because they could not perceive the subtle smell of putrescine, the participants showed defensiveness and hostility towards the author. It also demonstrated that unconscious exposure to odors elicited protective behaviors in participants.
