Being grateful can reduce your risk of suffering a heart attack.
A new study quizzed over 900 people on how much they agreed with the statement, 'I have so much in life to be thankful for', as well as being questioned on how strongly they felt 'grateful to a wide variety of people'.
The results showed that those who expressed the most gratitude were less likely to have a heart attack in the next four to nine years.
Psychologist Brian Leavy, who led the study for Maynooth University in Ireland, said: "The results obtained have provided further evidence that positive emotions, like gratitude, are associated with better health outcomes, particularly in promoting cardiovascular health."
However, the research found that people with high levels of gratitude only had a reduced risk of a heart attack if stressful situations increased their heart rate.
