Could Having a Sense of Purpose Lengthen Our Lives?

Over the last few years, aging experts have been looking at the role played by a sense of purpose—the feeling that our lives have meaning, and that we have a place in the world, that we make a difference. A number of studies have found that having a sense of purpose motivates us to take care of ourselves, reduces stress, and lowers the risk of a host of ailments that become more common as we age.

In November 2014, an article appearing in The Lancet suggested that having a sense of purpose can even add years to our lives. As reported by University College London (UCL), seniors who experienced a certain type of well-being were 30 percent less likely to die over the course of a study that was conducted by researchers from UCL, Princeton University and Stony Brook University. The researchers explained that “eudemonic well-being” is the positive feeling we get when we feel that what we do is worthwhile and that we have a purpose in life.

Explained study leader Professor Andrew Steptoe, Director of the UCL Institute of Epidemiology, “We cannot be sure that higher well-being necessarily causes lower risk of death, since the relationship may not be causal. But the findings raise the intriguing possibility that increasing well-being could help to improve physical health. There are several biological mechanisms that may link well-being to improved health, for example through hormonal changes or reduced blood pressure. Further research is now needed to see if such changes might contribute to the links between well-being and life expectancy in older people.”

The study appeared in the Nov. 6, 2014 issue of The Lancet. [optional link: http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2813%2961489-0/fulltext]
