    A trip to the theater, museum or art gallery could help you live longer. And the more often, the better, a new study suggests. Researchers from University College London (UCL) found that people engaged in the arts more frequently had a 31% lower risk of dying early when compared to those who didn't. Even going to the theater or museum once or twice a year was linked with a 14% lower risk.

“While other health behaviors like smoking, alcohol and exercise are undoubtedly bigger predictors of the rate of death, these leisure and pleasure activities people don't think as a health related activity do support good health and long life,” said Fancourt, an associate professor at UCL’s Research Department of Behavioral Science and Health.

How often an individual engaged in art activities, also including exhibitions, concerts and opera but not cinema, was measured at the start of the study in 2004 to 2005. The study looked at a range of economic, health and social factors to try and explain why there is a link between “arts engagement” and living longer, although as an observational study it can't establish cause. Part of the reason, the study said, comes down to social and economic differences among those who go and don't go to museums, exhibitions and art galleries. Wealth, they found, explained about 9% of the association. Cognitive(认知的) differences, social engagement and mental health also played a role.

“Things like free time and occupational status made no material difference,” said Fancourt, “but engagement in arts can reduce stress and build creativity that allows people to adapt to changing circumstances. It also helps people build social capital — accessing emotional support and information that helps people age more successfully. A greater sense of purpose could also play a role. If this (study) is added to the larger body of evidence, we are getting an increasingly rich picture on how arts can benefit health and it's not about one single outcome. It can have wide ranging benefits and support healthier lives lived longer.”

This study did not look at the effects of taking part in art-related activities but a World Health Organization review of available evidence published last year found that both receptive participation, like visiting a museum, and active participation, like singing in a choir, had health benefits.
