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.<\/strong><\/p>\n 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.<\/strong><\/p>\n Keep reading to learn more.<\/strong><\/p>\n What cannot be explained by science is often referred to as a \u2018sixth sense\u2019 by people. And sometimes, scientific research comes out which ends up confirming what humans had long suspected with their sixth sense.<\/p>\n According to research, when a person dies, their\u00a0body<\/a>\u00a0immediately 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.<\/p>\n Researcher Arnaud Wisman from the University of Kent\u2019s School of Psychology in Canterbury, UK, and Ilan Shira from the Department of Behavioral Sciences in Arkansas\u2019 Tech University in Russellville, Arkansas, shared that much like\u00a0animals<\/a>, 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.<\/p>\n 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. \u201cWe do not know why we like (or dislike) someone\u2019s smell, and we\u2019re usually not aware of how scent influences our emotions, preferences, and attitudes,\u201d Wisman and Shira\u00a0stated<\/a>.<\/p>\n \u201cIt is hard to think of a scent as frightening,\u201d other researchers have claimed. But it is not untrue that scents make people more alert about their surroundings.<\/p>\n 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.<\/p>\n \u201cPutrescine signals a different type of message than pheromones, but people\u2019s responses to putrescine (avoidance and hostility) do seem indeed to be the opposite of responses to many sexual pheromones,\u201d\u00a0one researcher explained.<\/p>\n
