The Heart-Mind Connection How Thoughts and Emotions Affect Our Heart Health by Ronica O’Hara
“D
oes your wife show you her love?” In a study of 10,000 married men, this question turned out to be revelatory. Among men with high levels of anxiety, a whopping 93 percent that answered “No” developed angina-related chest pains within five years—nearly twice the rate of those answering “Yes.” This 1976 Israeli study was one of the first to clearly document how emotions affect the physical heart. Today, the research is so vast and compelling that last year, the American Heart Association issued a statement urging that psychological factors be taken into account in cardiovascular care—which may result in doctors asking patients about depression and anxiety as well as testing for blood pressure and cholesterol levels. “What’s on your mind really does affect your heart,” says leading researcher and cardiologist Michael Miller, M.D., author of Heal Your
Heart and director of the Center for Preventive Cardiology at the University of Maryland Medical System. “Our hearts require emotional health in order to maintain cardiovascular health.” Two emerging fields are probing the mind-heart connection: neurocardiology, which studies their neurological interplay; and behavioral cardiology, which examines how psychological and social factors lead to heart disease. Increasingly, researchers are documenting that the brain and the heart form an intricate feedback loop that works neurologically, biochemically and electromagnetically to optimize well-being. What hurts one—be it artery-clogging foods or angry outbursts—can hurt the other. What heals one—be it exercising or a good belly laugh—can heal the other. There’s good news in that, says Miller: “You can heal your heart by actively engaging in positive emotions each and every day.”
