A woman has said she was left “fighting for her life” after receiving multiple health alerts while watching Terrifier 3.
The incident reportedly occurred while she was seated in a cinema during a screening of the film. She later shared her experience on social media.
The movie follows the character Art the Clown, played by David Howard Thornton. In the latest installment, the character returns from the dead to cause further violent chaos.
The release has already generated strong reactions among horror fans. Some viewers have described feeling deeply unsettled during screenings.
At the UK gala premiere, nine people reportedly walked out after watching only the opening scene. Audience members described the opening moments as difficult to endure.
The reactions added to the film’s growing reputation for extreme content. The premiere response quickly circulated online.
One fan said her Apple Watch issued repeated heart rate warnings during the film. Sharing her experience online, she wrote: “Was fighting for my life tonight during Terrifier 3 and loved every second.”
The post included an image of her heart rate data. The readings appeared to show a significant increase.
Medical context and expert commentary
According to the National Health Service, a normal resting heart rate for adults ranges from 60 to 100 beats per minute. In the shared image, the woman’s heart rate appeared to rise above 120 beats per minute. The increase occurred while she was seated and watching the movie.
The American Heart Association says it is normal for heart rate to rise when a person feels frightened. It explains that fear can trigger a surge of adrenaline in the body.
This response pushes the body into what is known as fight-or-flight mode. The reaction can happen suddenly.

“The brain triggers a surge of adrenaline, which makes the heart beat faster,” the association explains. It also notes that the response affects multiple systems in the body.
These include perspiration, blood flow, and hormone release. Blood is redirected toward major muscle groups.
Doctor Vincent Bufalino, a cardiologist and president of Advocate Medical Group, commented on fear-related heart responses. “It’s measured on how big the scare is,” he said. He explained that adrenaline can, in rare cases, trigger cardiac-related events.
Bufalino added that such outcomes are unlikely in everyday scare situations. He said it would be a stretch to link serious cardiac events to typical fright scenarios. “This is the kind of thing that you can’t prepare for,” he said. He added that outcomes depend on how the body reacts.
Medical professionals advise caution for people with pre-existing heart conditions. Sudden adrenaline surges may present greater risks for those individuals.
Doctors recommend discussing concerns with a healthcare provider. The guidance applies to intense emotional or physical stimuli.
