Can’t be bothered to hit the gym? Don’t worry, binge watching a horror movie will do the same thing.

Researchers from the University of Westminister in the UK revealed watching 90 minutes of an adrenaline-inducing movie can burn an average of 113 calories. FYI that’s equivalent to a 30-minute walk.

The University examined a group of participants while watching a series of scary films and monitored their heart rate, oxygen intake and output of carbon dioxide. The data found that the scary stimuli caused participants’ bodies to release adrenaline, which triggers the nervous system’s fight or flight response.

When in a fight or flight mode, the researchers concluded this triggers the body to start burning fat stores for energy while also releasing blood sugar. Additionally, it also works as a metabolism booster. They also found that the scarier the film, the more calories were burned.

“It is the release of fast-acting adrenaline, produced during short bursts of intense stress, or in this case, fear, which is known to lower the appetite, increase the basal metabolic rate and ultimately burn a higher level of calories,” Dr Richard Mackenzie, a metabolism specialist at the University of Westminster, told the Daily Mail.

The movie that slashed the most calories was the iconic 1980s film, “The Shining” (184 calories), followed by “Jaws” with 161 calories and “The Exorcist” with 158 calories.
