You know how non-horror fans can't understand just WHY we love gore and destruction? 'But WHY would you want to watch these gruesome things happen?' they cry. Perhaps a bit of science will help explain...

Horror movies boost your immune system

In this study, scientists observed leukocyte (white blood cell) activity in people watching The Texas Chainsaw Massacre! Apparently, the psychological stress of Tobe Hooper's masterpiece increased white blood cell count - leaving horror fans better equipped to fight disease and repair bodily injury.


Horror sharpens our carefully-evolved preservation instincts

Scientist Dr Clasen posits that watching a horror movie is 'an ‘emotional simulator’ to broaden our horizons. Horror fiction exercises our reactions to what’s terrible and frightening.' - it's like a test drive for a genuine horrific event.


Watching a horror movie is...kind of...exercise?

Scientists found that in two test groups, one watching a horror and the other a romance, the horror audience had increased resting metabolic rate - to you and me, that means you burn more calories being scared!


Like animals play-fighting, humans use horror to 'train' ourselves

We may not have to flee from saber-toothed cats any more, but our ancestors' desire to test and prepare our disaster-reactions has stayed in our DNA. Clasen continues: 'When we watch a horror movie, we’re satisfying that desire. We’re training our danger preparedness.'


We just straight-up enjoy being scared

It was long theorized that people only enjoyed horror because they were excited rather than scared, but Andrade and Cohen have combatted this idea. Horror fans 'experience positive feelings while still experiencing fearfulness' - that is, we just plain LOVE getting scared!
