Most children are born with the components of favorable cardiovascular risk—good blood pressure, lipid, and glucose levels; ideal body weight; and not smoking. If they can hold onto those assets, keep their weight down, and not get diabetes, they can avoid cardiovascular disease later. These researchers wanted to identify early psychosocial factors that safeguard and promote cardiovascular health into adulthood.
In this study, researchers review seven types of evidence that shows high subjective well-being (SWB)--including life satisfaction, absence of negative emotions, optimism, and positive emotions--cause better health and longevity. Examples of each type of evidence are described, and issues such as causality, effect size, methodological rigor, whether too much happiness can be detrimental to health, and whether there is a threshold effect for SWB are discussed.
