There’s huge amounts of research into the effects of our emotions on our health. It seems to have been established that negative emotions like anger, anxiety, bitterness, un-forgiveness and depression release chemicals into our system that weaken our immune system and reduce its ability to fight disease. And positive emotions like happiness, gratefulness, pleasure, love and kindness produce chemicals that strengthen the immune system. Following quotes by experts suggest a direct link between stress and heart diseases, especially in women:

“Because men’s hearts aren’t as responsive to emotional stimuli, emotion is a more important predictor of heart problems in women. Hurtful emotions can cause a woman’s arteries to spasm and close down like a boa constrictor squeezing around its prey.” (Dr. Mehmet Oz, MD, Cardio Surgeon at NY-Presbyterian/Colombia University.)

“Stressful emotions account for roughly 30 percent of all heart attacks. They rank at par with high blood pressure and abdominal fat, straining the heart by increasing your rate and flooding your body with high levels of potentially toxic hormones like cortisol and adrenaline.” (Landmark Interheart Study – a survey of heart disease in 24,000 people in 53 countries)

“Stress from negative emotions also makes the blood clot faster, adding to heart disease risk. Stress can also play an indirect role in heart disease by interfering with exercise, a healthy diet and adequate sleep.” (Karina Davidson, Ph.D., co-director of the Center for Behavioral Cardiovascular Health at Colombia University Medical Center)

“Anger, anxiety and depression are the main ways women channel stress, and each emotion has a profound effect on the heart.” (Redford Williams, MD, Director of Behavioral Research at Duke University and author of In Control.)
