This study examined the relationship between psychological well being (using measures of vitality and optimism) and hypertension, finding that high emotional vitality but not optimism significantly predicted a reduced risk of hypertension.
Understanding psychological factors that may be linked to disease can lead to innovative prevention and treatment efforts. This study examines a positive psychological characteristic—purpose in life—and its relationship to stroke.
This study examines the impact optimism has on serum lipids, including total cholesterol, LDL and HDL cholesterol, and triglycerides. This research found that optimism was positively correlated with HDL cholesterol and triglycerides, but was not associated with LDL cholesterol and total cholesterol.
Health—whether psychological or physical—is characterized not just by the absence of disease but increasingly by the presence of well-being. These researchers looked at the relationship between psychological well-being (marked by optimism, happiness, and life purpose) and serum antioxidants such as carotenoids and Vitamin E, which are indicators of physical health.
People who have positive psychological well-being may be more likely to engage in heart-healthy behaviors such as exercising, eating a healthy diet, and avoiding smoking, all behaviors that also reduce their risk of cardiovascular disease. These researchers reviewed the evidence linking well-being and health behaviors, and described strategies to enhance well-being studied by others, and the implications for cardiovascular health.
