Your nose is the first indicator if you are close to death
It is in our human nature to believe in death in our minds, and the way we visualize death is also related to the appearance of a dead animal, human, bird or mosquito. So what’s the connection between them all, but we haven’t really thought about it before? smoking.
According to current research, the human nose is able to perceive a variety of smells, which cannot be identified in a particular category, but still respond to them. Like the smell developed by a chemical known as putrescine. This is a chemical that the body produces when it begins to decompose, and there is a little problem to know, which is that the smell is caused by the evil behavior of the animal over the years of evolution. These reactions are believed to have evolved at least 420 million years ago.
It is believed that animals respond to the scent of putrescine as a sense of danger through two different techniques: the reaction that a predator is nearby, and the second is that they are in danger of life, so their instinct tells them to run.
Scientists conducted 4 different experiments on humans with a mixture of putrescine, water and ammonia, just to prove that human reactions and behaviors are no different from the reactions and behaviors of animals.
The first experiment, in which participants were tested specifically for the scent of putrescine, were exposed to its scent and an alertness test. The results showed that participants exposed to the scent of putrisin showed significantly greater alertness than those exposed to ammonia and water.
The researchers just conducted the second test where they tested a group of unsuspecting people who were shown the function of smell, namely intensity, fatigue and fame. The researchers wanted to see the group’s reaction to the smells, and how quickly the participants escaped at a distance of 80 metres. Those who smelled the putrescine tended to get away from the site faster, proving that the scent elicits a strong escape motive.
In another experiment, immediately after the group was exposed to the scent of putrescine, the researchers gave the participants a task to complete the stress with the word.
The results showed that the scent of putrescine led the group to the word total strains, all of which are associated with escape and other associations with the word escape. The smell also reached the level of using personal words.
defensive and hostile
In the latter experiment, participants were exposed to a scent so creamy that they were unable to detect it. In this experiment, they were shown the text of the study, the task of which was to evaluate the author.
They could not detect the exact smell of putrescine, and the participants showed a defensive and hostile attitude towards the author. This also showed that subconscious exposure to the scent elicited defensive behavior in the participants.
