• Optimistic People More Immune Heart Disease

    Cheerfulness can protect a person from heart problems, U.S. health experts said.

    People who are happy and optimistic to have a lower risk of heart disease, according to the Harvard School of Public Health study of 200 case studies as published by the Psychological Bulletin.

    Cheerful people who are generally healthier and scientists suspect that a peaceful heart, can reduce the various risks such as high blood pressure and cholesterol.

    Stress and depression are also associated with heart disease.

    Harvard researchers examined data from medical tests to find studies that noted the relationship of psychological health and heart health.

    This study reveals a number of factors such as optimism, life satisfaction and happiness associated with reduced risk of heart disease and diseases associated with the circulatory system, regardless of economic status, smoking habits and weight.

    Heart disease risk 50% lower in individuals who are optimistic.
    'No proof'

    Objectively measuring mental health is not only difficult, but cardiac risk factors like cholesterol and diabetes are also important to reduce the risk of the disease.

    Optimistic people mentioned in these case studies also make healthy lifestyle behaviors such as exercise and a balanced diet.

    However, although factors such as sleep quality is also taken into account, the link between being optimistic and better cardiovascular health remains strong.

    Maureen Talbot, a senior cardiac nurse at the British Heart Foundation said, "The relationship between heart disease and mental health are complex and not fully understood.

    "Even though this study did not look at other effects of stress, this study confirms what we already know that psychological health is an important part of a healthy lifestyle, such as sporting activities and healthy eating."
