Do optimists really live longer?

A number of studies have shown that optimists enjoy higher levels of well-being, better sleep, lower stress and even better cardiovascular health and immune function. And now, a study links being an optimist to a longer life. What makes these findings especially impressive is that the results remained even after accounting for other factors known to predict a long life.

Optimism is typically viewed by researchers as a relatively stable personality trait that is determined by both genetic and early childhood influences (such as having a secure and warm relationship with your parents or caregivers). But if you’re not naturally prone to seeing the glass as half full, there are some ways you can increase your capacity to be optimistic. 

For example, visualising and then writing about your “best possible self” (a future version of yourself who has accomplished your goals) is a technique that studies have found can significantly increase optimism, at least temporarily. But for best results, the goals need to be both positive and reasonable, rather than just wishful thinking. Similarly, simply thinking about positive future events can also be effective for boosting optimism.
