We often come across the expression “bloodcurdling” when we watch or hear something scary. We always knew that this was a metaphorical use. But what if it isn’t?
“Does blood really freeze? No way!” Don’t say that because if you only heard about the changes that occur in our bodies in moments of fear, you wouldn’t think this was impossible either!
New research on fear, Fear is in our bloodstream It shows that it has a huge impact. So what is this blood-curdling effect?
The expression “blood-curdling” actually dates back to the Middle Ages.
At that time, people believed that petrification to cool the bloodThey believed that it could even cause frostbite. Medicine and science were not so advanced at that time, but this concept has existed for a long time.
Dr. Banne Nemeth“There may be some truth to these old statements. When you experience fear, some changes occur in your body. Adrenaline is released, fight or flight responses occur. It would be interesting to investigate whether this statement is true.” He explains the situation using his expressions.
Banne and his research team divided 24 healthy volunteers under the age of 30 into two groups.
A group of “Sneaky” while watching horror movie The other group watched this movie in reverse. Both groups were shown the same length documentary “A Year in Champagne”. Participants were not given any information about the subject of the films or the hypothesis of the study.
Analyzes made on blood samples taken from the participants 15 minutes before the start of the movie and afterwards showed that fear physiological reflections It gave important clues for research.
One participant fainted from fear despite eating a box of chocolates while her blood sample was being taken.
Researchers, watching horror moviesThey found that it caused a significant increase in the clotting protein called factor VIII, which plays a role in the blood clotting process. However, no relationship was found between this increase and other clotting molecules.
As a result of this research, the real reason for the increase could not be determined with certainty, but They put forward a hypothesis on the subject.
It may make sense to consider this issue from an evolutionary perspective.
The hypothesis reached as a result of the research is when your body encounters scary situations It seemed like he was bracing himself for potential blood loss. This is a finding consistent with the association of fear with injury.
If the frightening situation causes an injury, the body is prepared in advance and thus can react faster, the blood can clot faster, and thus It shows that blood loss can be reduced.
Even if medicine hasn’t developed that much, maybe medieval people He wasn’t wrong, fear; It could actually turn out to be an advantage in the fight for survival.
