Happier, more satisfied people lower their risk of long-term illnesses, it said.
Meanwhile unhappy folk spend an unhealthy amount of time watching television, smoke more and eat worse diets – without enough fresh fruit and cheese, the researchers said – speeding up their decline.
Experts from Shanghai Jiao Tong University in China said there is a “close association” between psychological stress and physical illness.

The research used data from 2.3million across Europe, including the UK.
It compared their scores on life satisfaction, positive outlook, depressive symptoms and neuroticism with health issues linked to ageing.
Worse mental health was linked to higher rates of habits and illnesses known to shorten people’s lives – like too little exercise, heart diseases and breast cancer.
Writing in the journal Nature Human Behaviour, Prof Wang said there was a “causative” link between the mental and physical.
She said: “We found that better mental wellbeing was associated with higher resilience, self-rated health and healthspan.
“Mental health has long been recognised as a fundamental factor in the biological processes of multiple health conditions.
“We unearthed a protective impact of mental wellbeing on healthy ageing, which held regardless of income, education or occupation.”

Researchers said there were 33 factors connecting mental health to physical ageing.

Depression and anxiety are most common, and figures show millions of older people have worse mental health because they are lonely.
The charity Age UK reckons 1.4million Brits are experiencing loneliness.
Prof Wang added: “Our results underscore the importance of prioritising mental wellbeing in health policies geared towards healthy ageing.
“Interventions could promote healthy lifestyles such as restricting TV watching time, avoiding smoking, enhancing cognitive function and preventing common diseases.”
