Purpose helps people live longer while lacking a strong purpose leads to shorter life according to a new study.
The mechanisms for which life purpose may affect longevity are thought to be associated with increased well-being. Previous research suggests that greater sense of well-being was associated with lower cortisol levels and lower levels of pro-inflammatory cytokines which decrease expression of pro-inflammatory genes. No known studies have looked at interventions in purposeful living and associated effects on inflammatory biomarkers.
Cause specific mortality was less clear vs all-cause mortality with associations evident in only heart and blood diseases, and digestive tract system disease.
