Today, I’d like to share a powerful way to keep your heart healthy. You have probably had your blood pressure, cholesterol levels, and triglycerides checked as part of your preventive medical exams. You may have been given recommendations about keeping trans fats out of your diet, drinking a glass of red wine, exercising regularly, and maintaining a healthy weight. And you may be taking antioxidants, vitamin D, fish oil, or medications to keep your heart healthy.
However, there’s a vital part of a heart-healthy lifestyle that doesn’t get enough attention: love. You see, there's a connection between love and the heart that goes beyond Valentine's Day cards and Shakespearean sonnets. In several different ways, love in fact helps prevent heart disease. Cardiovascular research shows that experiencing feelings of love, appreciation, and gratitude have immediate and long-term effects on how your heart functions. These effects counteract the damaging effects of stress and negative emotion on your heart and blood vessels.
THE DETAILS: It's not difficult to demonstrate how love and the heart interact. Recently, I saw a patient, Jenny, who was referred to me for biofeedback to help her reduce high blood pressure. I hooked Jenny up to a sensitive pulse-rate monitor that enabled her to see how her heart rate was influenced by her emotions. I gave her a couple of stress challenges: Count backwards by from 500 by sevens and then tell me about a recent stressful event. With each stressor, her heart rate soared and her heart rhythm became disorganized. This is normal. Stress disrupts heart rhythms. I asked her to think of something that made her angry. Her heart rate spiked again.
Then I asked her to think about someone she loves, or feels grateful for. Her heart rate came down almost immediately, and her heart rhythm became smoother and more regular. She was amazed to see how immediately her heart responded to her emotions.
WHAT IT MEANS: Your heart, the same organ that pumps blood through your body, is also an organ of emotion. It may not be the seat of emotion, as was once thought. But it responds to emotion, nonetheless. Anger, hostility, anxiety, and depression all cause a cascade of physiological reactions that contribute to heart disease. When you experience these stressful emotions for a prolonged period, your body responds with the perfect cardiovascular storm:
• Increased heart rate and intensity
• Increased blood vessel constriction and blood pressure
• Increased damage to epithelium, the cells lining your blood vessels
• Increased platelet stickiness (clotting)
• Increased inflammation
• Increased blood vessel calcification (stiffening)
• Disruption of heart’s electrical rhythm
Over time, these processes contribute to the deposition of atherosclerotic plaque in blood vessel walls, and to heart rhythm abnormalities. And this greatly increases the risk of heart attack and stroke.
