Here’s some good news: A new study has found that an increase in happiness is directly related to a longer life. Needless to say, the challenge for individuals and societies is to determine what happiness and wellbeing consist of in today’s world — and and then promoting it through public policies.
But let’s take a look at the research: The study was based on 4,478 participants of a nationally-representative survey that examined the association between happiness and the subsequent likelihood of dying due to any cause, between 2009 and 2015. The survey was focused on individuals 60 years and older living in Singapore. The research, conducted by Duke-NUS Medical School was published in the journal Age and Ageing,
As described in this summary, the researchers found that among happy older people, 15% died prior to the end of 2015. But it was 20% among unhappy older people. Every increase of one point on the happiness score lowered the chance of dying due to any cause among participants by an additional nine percent. The likelihood of dying due to any cause was 19 percent lower for happy older people. The inverse association of happiness with mortality was consistently present among men and women, and among the young-old (aged 60-79 years) and the old-old (aged 75 years or older).
“The findings indicate that even small increments in happiness may be beneficial to older people’s longevity,” explained senior author Rahul Malhotra. “Therefore individual-level activities as well as government policies and programs that maintain or improve happiness or psychological well-being may contribute to a longer life among older people.”
June May-Ling Lee, a co-author, added that the consistency of the data about the association of happiness with mortality across age groups and gender shows that all men and women – the young-old and the old-old, — all are likely to benefit from an increase in happiness.
Previous studies have linked happiness or positive emotions with a range of better health outcomes, but the evidence on the effect of happiness on living longer has been inconclusive. Many previous studies have found happiness to be associated with a lower likelihood of dying, but this link disappears once differences in demographic, lifestyle and health factors between those less and more happy are accounted for. This study, however, assessed the association between happiness and mortality among older people, while accounting for several social factors, such as loneliness and social network.
