The researchers then compared these scores with mortality rates of the participants over the next five years. During that time, 776 of the participants died.

In particular, those with lower life-purpose scores were more likely to die from heart or blood conditions.

"Previous research has suggested that volunteering and meditation may improve psychological well-being."

Past studies have shown that stronger well-being, including purposeful living, decreased the activation of genes that trigger inflammation in the body. Inflammation, in turn, has been previously linked with an increase in risk of early death, according to the study.

But no studies have directly measured such molecules or biomarkers and related them to health outcomes or mortality.
