We’ve Got Some Bad News For Horror Movie Fans…

Will you be celebrating a Very Merry Goth-mas this season? More of a Scream over Love Actually person come the 25th December? Then we’ve got some very sad news to break to y’all…

According to new research watching horror films as well as scaring the s*** out of you, could actually be bad for your health, scientists have warned. Yup, a recent study found watching scary films actually boost a blood clotting protein which is known as Factor VIII.

Yup, this may seriously make you think twice before settling down to watch a film that’s more fright than love fest this weekend.

The research published in The BMJ suggests that using the term ‘bloodcurdling’ to describe feeling extreme fear is actually pretty justified.

“We found watching horror, or ‘bloodcurdling’, movies was associated with an increase in blood coagulant (Coagulant is a substance that causes blood to thicken) factor VIII,” says Dr Banne Nemeth at Leiden University Medical Centre. The Dutch researchers who set out to assess whether acute fear can curdle blood say it poses an important evolutionary benefit – by preparing the body for blood loss during life threatening situations.

We may be giving The Shining a miss…


For the study 24 people, aged 30-years old or younger, were split up – with 14 watching a scary movie followed by a non-threatening educational movie and the other 10 volunteers watching them in reverse order.

The results? All participants had similar baseline levels of coagulant factor VIII before the films and 57% of participants had increased levels after watching Insidious. Um, so not great then.

Dr Nemeth added though: “The underlying biological mechanism of acute fear associated with an increase in coagulation activity is still to be unraveled,” he says.

Okay, so while watching Horror movies may not put you at immediate risk, we’re still sticking to Love Actually this Christmas. Just incases…
