The Mysterious Signs of Coming Death
It’s not unusual to overhear family members sharing stories about a loved one who has passed away. One curious and fascinating topic that often comes up is how some people behave differently just before they die.
They might say heartfelt goodbyes, try to fix broken relationships, or even give away cherished possessions. It’s almost as if they know something important that no one else does.
Some people think these behaviors are just coincidences, while others firmly believe that individuals somehow sense when death is nearby. It’s a natural part of our human experience to wonder about the meaning of our loved ones’ passing and to ponder what happens in those final moments.
Scientists have discovered that when someone dies, the body begins to break down almost immediately. This process produces substances like putrescine, a foul-smelling compound that signals decay.
Interestingly, researchers believe that humans can subconsciously recognize this rotten odor. When it is released, it triggers an instinctive response in us, similar to a warning bell.
Animals, too, have a keen ability to smell danger, often reacting swiftly to protect themselves from predators or threats in their environment. This instinct is in tune with survival—whether it’s a larger animal from their pack or a looming danger, their reactions are critical for survival.
A study by Arnaud Wisman from the University of Kent and Ilan Shira from Arkansas Tech University showed that the way animals detect these dangerous scents might not be so different from how humans do.
Both species use their senses to identify threats, and the smell of putrescine can serve as a warning signal for humans, stirring reactions both conscious and subconscious.
In their research, Wisman and Shira conducted four experiments involving putrescine, ammonia, and water to see how participants would react.
One startling experiment revealed that when people were exposed to putrescine in a controlled setting, their immediate reaction was to step back or move away from the area. This instinctual response is akin to the fight-or-flight reaction.
“When faced with real danger, animals have two choices—fight or flee,” the researchers noted. “Surprisingly, humans often react in a similar way.” This realization blurs the lines between how different species respond to threats.
But it’s not just putrescine we respond to. Humans have a natural reaction to other scents as well, like sweat. Studies have shown that sweat collected from people in fearful situations can evoke a startle reflex in others when they smell it.
Wisman and Shira explained, “We do not know why we like (or dislike) someone’s smell, and we’re usually not aware of how scents affect our emotions and preferences.” They continued, “It’s hard to consider a smell as frightening, yet these scents make us more alert and aware of our surroundings.”
When danger arises, many humans tend not to confront it head-on. Most people avoid conflict, whether it’s verbal or physical, preferring to distance themselves until they feel they have no choice but to fight. Meanwhile, reactions may vary among individuals, but the profound effects of putrescine and sexual pheromones reveal the power of scent in our lives.
Pheromones are chemicals our bodies release to attract potential mates, while putrescine sends a warning signal. “The message of putrescine is different from that of pheromones,” Wisman and Shira pointed out, “but the ways people react—avoiding or feeling hostile toward putrescine—are indeed opposite to how they typically respond to sexual pheromones.”
Interestingly, study participants weren’t aware that they reacted negatively to the scent of putrescine. “People are not familiar with putrescine and do not consciously connect it with fear or death,” the researchers explained.
This research opens a window into our understanding of life and death, revealing how deeply our senses are tied to our instincts. As we reflect on these complex topics, it’s natural to be curious.
