Top 10 Horror Movies Ranked by Heart Rate in 2024 + Where To Watch
What’s the scariest horror movie ever? It’s the ultimate debate for every Halloween hangout or horror movie marathon. But instead of just arguing about it, Science of Scare decided to get scientific about fear—using heart rate monitors to figure out which films truly make our hearts race. Let’s dive into how they did it and count down the movies that’ll make your pulse pound!
How Does Heart Rate Reveal Fear?
Here’s the deal: when we’re scared, our body goes into fight-or-flight mode. Your heart starts pounding, pumping oxygen-rich blood to your muscles, just in case you need to run from a ghost—or, you know, that creepy figure in the corner.
To measure the fear factor, Science of Scare strapped heart rate monitors onto brave volunteers while they watched horror movies. They tracked three key stats:
Average BPM (Beats Per Minute): How fast your heart races while watching.
BPM Spike: The highest single moment of terror in the movie.
Heart Rate Variance: How much your heart rate jumps around (measuring tension and stress buildup).
Using this data, they created a “Scare Score,” blending jump scares with slow-burn suspense to give us the ultimate ranking of horror movies. Are you ready?
