“Does blood really freeze? Not really!” 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 it impossible!

New research into anxiety, 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 in petrification to cool the bloodThey believed it could even cause frostbite. Medicine and science weren’t that advanced back then, but this concept has been around for a long time.

Dr. Ban Nemeth“Perhaps there is some truth in these old statements. When you experience anxiety, changes take place in your body. Adrenaline is released, fight or flight responses arise. It would be interesting to investigate whether this statement is true is.” He explains the situation with his facial expressions.

Banne and his research team divided 24 healthy volunteers under the age of 30 into two groups.

A group of “Sneaky” while watching a horror movie The other group watched this film 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 of blood samples taken from participants fifteen minutes before the start of the film and afterwards revealed this fear physiological reflections It provided important clues for research.

One participant fainted from fear despite eating a box of chocolates while her blood sample was taken.

Researchers, watching horror movieThey found that it caused a significant increase in a clotting protein called factor VIII, which plays a role in the blood clotting process. However, no link was found between this increase and other clotting molecules.

As a result of this investigation, the actual reason for the increase could not be determined with certainty, but They put forward a hypothesis on this topic.

It may be useful to look at this issue from an evolutionary perspective.

The hypothesis arrived at as a result of the research is when your body encounters scary situations It seemed like he was bracing himself for possible blood loss. This is a finding consistent with the association between anxiety and injury.

If the frightening situation causes an injury, the body is prepared in advance and can therefore 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 yet, maybe medieval people He wasn’t wrong, fear; It could even prove to be an advantage in the fight for survival.
