How Happy You Are Dictates How Healthy You Are


Happy people are healthier and live longer. By now this notion is supposed to be a common belief that dictates lifestyle choices. Chronic unhappiness can be a true health threat that has to be kept under control with planned interventions.

Scores of studies show that our levels of happiness versus stress and depression can influence our cardiovascular health, our immune system strength to fight off diseases, and our ability to heal from injuries.

A new review indicates that subjective well-being — factors such as life satisfaction and enjoyment of life — can influence physical health. The review’s investigators also examine why this is so and conditions where it is most likely to occur.

Subjective well-being may exert its effects on physical health through health behaviors, as well as through the immune and cardiovascular systems. Although scientists still are exploring and debating when happiness most affects health, there is no doubt that it can do so.

With more research, it may one day be informative for clinicians to monitor individuals’ subjective well-being just as other factors are currently assessed. Individuals should also take responsibility for their health by developing happy mental habits.

People’s feelings of well-being join other known factors for health, such as not smoking and getting exercise.
