The impact of the health horror films inspired by scientists

unusual - Horror and terror. This film genre has the reputation of us "bloodcurdling" and the expression might be more truthful than we think. A group of Dutch researchers was actually interested in the effects of these "works" on health and revealed that horror films influence the rate of a protein which plays a central role in blood clotting.

each year-end, the serious medical revue "

British Medical Journal (BMJ)

" abandoned his usual research subjects in favour of mischievous and surprising studies. Program of its last cuvée, articles on the use of the MRI

to locate the spirit of Christmas in our brain

,

the largest consumers of caffeine

in the medical corps or a survey on

the veracity in the films in the "Austin Powers"

saga. And, therefore, the consequences of horror on our bodies.

Professor of epidemiology Banne Nemeth, two other doctors and a researcher of

medical center the University of Leiden

in the Netherlands have decided to drive

a study on the impact of terror on our

hemoglobin. To complete their experience, they have screened 2 films to a group of 24 young healthy volunteers.

initially, 14 of them were entitled to

Insidious

, a horror film with evil forces and Paranormal phenomena. The following week, same day and same time, they looked

A year in Champagne

, a documentary on the backstage of the achievement of one of the most famous wine in the world. The other 10 volunteers have viewed these two films, but in the other direction. These viewers were placed 'in a comfortable environment', specify the authors of the study.

fifteen minutes before and after the meeting, blood samples were collected from the subjects of the study. The participants were subjected to conditions: no drinking or smoking during the day before watching, note the fear felt on a scale of 0 to 10. And in this area,

Insidious movie of course largely prevailed over the story bubbles in Champagne.

researchers measured the rate of

13 factors involved in the process of

blood clotting. These proteins that circulate in the blood, are involved in the formation of clots. At the end of the analysis, they found that only the rate of one of these factors,

factor VIII or anti-hemophilique A

, suffered the change during the experiment.

factor VIII plays an essential role in clotting. It is at the level of the intrinsic pathway, this mechanism that triggers the coagulation whenever a lesion is detected. If factor VIII is deficient in the body, it is responsible for hemophilia. Conversely, if bleeding is excessive, it may result in the formation of blood clots may hinder traffic (venous thrombosis).

gold, the study on the impact of the horror on our health has shown that factor VIII levels were increased in the blood over half of respondents (57%), against only 14% during the viewing of the educational film "A year in Champagne", explain the researchers. Levels had even declined in 18 people who looked at the educational film.

even though the study's authors acknowledge that, for the time being, their results are not of interest "evident", because only the factor VIII has undergone a change, they prefer to avoid a hazard. "A celebration of Christmas really relaxing and joyful without exposure to frightening situations, appear to be advisable to reduce the risk of venous thrombosis," they conclude.
