The 10 Scariest Movies Based On Measuring Viewers’ Heart Rates

Which is your favorite horror movie from this list?

While a few horror films make us jump out of our seats, almost ALL of them get our hearts racing especially during really intense scenes. In fact, some experts measured the heart rates of viewers watching horror films. Based on that, they were able to determine the scariest horror film. According to Brightside, the platform BroadbandChoices did a study where subjects watched horror films based on top ratings from IMDb, Rotten Tomatoes, and Reddit. The study stated that "watching each movie in 5.1 surround sound, our panel of 50 people consumed over 120 hours of the best horror movies, each fitted with a heart rate monitor to measure which movies got their blood pumping the most to find the ultimate horror movie and crown the king of fright night."
