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.
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.
Positive psychological well-being, especially optimism, protects against the incidence, and somewhat against the progression, of cardiovascular disease through a broad array of mechanisms, according to this extensive literature review.
