Scientists since long have been trying to find out whether watching horror movies is linked to bloodcurdling. Now in a new study researchers have found an answer whether or not fear causes blood clotting.

The findings of the study published this week in the British Medical Journal showed that the study was conducted on 24 healthy participants all around the age of 30 years or younger.

Researchers divided the participants into two different groups. The first group included around 10 participants and the other included 14 participants. The first group with 10 participants was assigned to watch a non-scary educational film followed by a horror film.

The second group was asked to watch the horror film followed by the educational film, viewed a week apart.

Researchers even collected blood samples of participants before and after viewing each film. After analyzing the samples, researchers found that there was an increase in coagulant factor VIII in more participants who viewed the horror film than those who watched the educational film.

“Levels increased in 12 (57%) participants during the horror movie, but only in three (14%) during the educational movie. Levels decreased in 18 (86 percent) participants during the educational movie, but only in 9 (43 percent) during the horror movie”, the team wrote.

Researchers noted that although there was an increase in one coagulant factor, there wasn't a corresponding increase in the proteins required for clotting to take place.

Researchers admit that some more study would be required, but were also confident that their findings will help in several medical treatments.
