Despite advancements in technology and years of research, certain aspects of the human body remain a mystery. One fascinating discovery is that humans, much like animals, may subconsciously sense when death is near.
When someone dies, the body releases putrescine, a foul-smelling compound produced during decomposition. According to researchers Arnaud Wisman and Ilan Shira, humans subconsciously recognize this odor, triggering instinctive reactions. Similar to animals fleeing danger, experiments revealed that people exposed to putrescine tend to move away, showing heightened awareness of their surroundings.
Although we often overlook how scents influence our emotions and behavior, this study highlights how survival instincts are deeply ingrained in humans. Unlike s ex pheromones, which attract and stimulate behavior, putrescine evokes avoidance and hostility, signaling danger on a primal level—even if we’re not consciously aware of it.
