Optimistic outlook ‘can cut’ risk of stroke

An optimistic outlook may reduce the chances of having a stroke, research suggests.

Scientists asked more than 6,000 adults over the age of 50 to rate their optimism levels on a 16-point scale, and compared the results with stroke rate.

They found that over a period of two years each point increase in optimism corresponded to a nine per cent reduction in stroke risk.

Previous research has associated an optimistic attitude with better heart health and enhanced immune systems.

Low pessimism levels and short-term positive emotions have also been linked to a lower risk of stroke.

The US scientists measured optimism levels with a widely used assessment test which allows participants to rank their own responses.

They made adjustments for factors that might affect stroke risk, such as chronic illness and other health issues, and social and lifestyle factors.

The scientists pointed out that the effects of being positive seemed to be felt very quickly, since the study participants were monitored for only two years. “Optimism seems to have a swift impact on stroke,” said study leader Eric Kim, a doctoral student at the University of Michigan.

“Our work suggests that people who expect the best things in life actively take steps to promote health.”

The protective effect of feeling positive may just be due to behavioural choices, such as taking vitamins, eating a healthy diet and exercising, said the researchers.

However there was some evidence that positive thinking can have a biological impact.

Sharlin Ahmed, from the Stroke Association, said: “There has been a long-term belief that positive thinking can improve your recovery after a stroke, so it’s interesting to see that it could also reduce your risk of having a stroke in the first place.
