Researchers analyzed the death ratio and chronic diseases in more than hundred thousand women aged above 50.

Researchers founded, women with good expectations and positive attitude towards life were 14 percent less apt to die from any disease than pessimistic people and have 30 percent reduced risk of heart diseases after the follow up of eight years.

The frequency of diseases or habits like hypertension, diabetes or smoking was also less common in the happy folks.

Researchers also compared the women with suspicious vision about others in the group called cynically hostile with the innocent and trusted women.

“The women of hostile group showed the distrust on the other people for the sake of safety. These findings showed a general suspicion of the people,” led researcher, Dr. Hilary Tindle said.

The death rate in cynically hostile women was 16 percent higher than the non-cynically hostile women during the study. The probability of death due to cancer was 23 percent more in such type of women.

This specific study doesn’t prove any worse health effect of pessimism or negative attitude but the researchers believe that gull thoughts, some how, affect the health.

“More research is needed to develop therapies which focus on bringing modification in people’s attitude and if that modifications provide any health benefits,” researchers said.
