If you have ever watched a scary film, you probably have interacted with some of the scenes, and you have been gripped by feelings of fear, but you must always remember that you are a lucky person who has not had a heart attack because of these scenes.

Over the past few decades, horror movies have led viewers to abort, shock, heart attack, heart problems, nausea, vomiting and fainting. Some have led to the deaths of some viewers, the Sun newspaper reported on Saturday.
A 65-year-old man suffered a fatal heart attack, watching "The Sorcery 2" in an Indian cinema in 2016, and complained of chest pains while the screen showed infected, bloodied children.
A 45-year-old man was reported dead in Chicago, United States, while watching the movie "The Predator".
When "The Spooker" was released in 1973, viewers were shocked by a number of movie theaters because of what they saw on the screen, many of them were unconscious, others vomited, and a woman was reportedly aborted.

What does science say?

Although these incidents may seem almost impossible or strange, science asserts that such films can kill many viewers, especially those who can not see scenes of horror.
In cases of extreme fear, the body mobilizes its forces to respond to these scenes, leading to the rapid pumping of adrenaline in the heart in preparation for escaping the body from danger or gathering energy to protect itself.
In the second phase of the body's own defense, adrenaline drives calcium into the brain, an important component of blood flow, but the large amounts in this case cause irregular heartbeat.
In the third stage, the force of blood flow to the heart may stop, because of its inability to treat this sudden and large blood flow, or there may be a drop in blood pressure, which makes the person lose consciousness, and may lead to death.
