Hearty dose of happiness good for you
You've heard it before: to avoid a heart attack, don't smoke, eat right and exercise. But it may help to be happy, according to a study, writes Maria Chang.
Researchers at Columbia University rated the happiness levels of more than 1,700 adults in Canada with no heart problems in 1995. After a decade, they examined the 145 people who developed a heart problem and found happier people were less likely to have had one.
The study was published online today in the 'European Heart Journal'.
"If you aren't naturally a happy person, try acting like one," said Dr Karina Davidson, the paper's lead author. She said happy people were more likely to have a healthier lifestyle.
