It may sound surprising, but millions of people around the world enjoy watching horror movies, even though these films often make them feel scared, anxious or uneasy. So why do people willingly choose to watch something that frightens them? According to researchers, the answer lies in the human brain.
This interesting insight came from a study conducted in Finland a few years ago. Researchers at the University of Turku examined how the brain reacts while watching horror films and why fear-based entertainment remains so popular.
The study revealed that horror movies trigger a unique mix of fear and excitement in the brain. During frightening scenes, the brain releases stress hormones such as adrenaline, which increase alertness and emotional intensity. At the same time, the brain understands that the threat is not real, allowing viewers to experience fear in a controlled and safe environment.
As part of the research, volunteers were shown some of the scariest and most iconic horror films of the past century. Researchers then analyzed how participants felt during and after watching the movies. Brain activity was closely monitored, and the findings showed that the brain continuously prepares itself to respond to perceived danger.
According to the researchers, horror movies can temporarily “trick” the brain, increasing excitement and emotional engagement. Films based on realistic threats or strong psychological elements were found to have a deeper impact on viewers compared to purely fictional or unrealistic horror.
The study also found that curiosity and thrill play a major role in why people keep watching horror films. Around 72 percent of participants said they watched at least one horror movie every six months. Despite feeling fear or anxiety, viewers were drawn by the inner excitement and desire to experience something intense and different.
Interestingly, researchers noted that horror movies also encourage social interaction. Most people prefer watching scary films with friends or family rather than alone, as shared fear can strengthen social bonds and make the experience more enjoyable.
The study further explained that as tension builds during horror scenes, parts of the brain responsible for detecting threats become more active. This heightened brain activity creates a strong emotional response, which many viewers find thrilling rather than unpleasant.
Experts say this combination of fear, excitement, curiosity and social bonding explains why horror movies continue to attract audiences worldwide, proving that sometimes being scared can actually be entertaining.
