While you might say that a scare "almost gave me a heart attack," the opposite may be true. Some medical professionals believe that an innocent scare now and then (say while visiting a haunted house or watching a scary movie) can, in fact, promote heart health. Michael Castine, cardiologist at Ochsner Medical Center, explained in a blog post that when scared, a person's adrenaline triggers the blood vessels to contract and re-direct blood toward the heart and lungs, in a "flight or fight" response. The result? "This can train your heart to pump more blood with every stroke—increasing your cardiac output up to eight times its resting capacity," Castine explained.
