Practical or positive?

A recent study says that positive psychology doesn't have any effect on physical health 

Positive attitude does not play any role in making people physically healthier or speeding up their recovery, a new study has revealed. One of the studies, which took into consideration 4,600 people with cancer over 30 years, found that irrespective of whether the patients were extrovert or neurotic, their attitude to life had no relationship with how long they survived their illness. 
    It is not an isolated finding. An analysis of research by Dr James Coyne, professor of psychology at the University of Pennsylvania School of Medicine, found that there were no good quality studies showing that 'positive psychology' had any effect on physical health, the Daily Mail reported. In one of his own large studies, he found that the sense of emotional well-being of cancer patients had no impact on how long they lived. 
    Claire Murrell, head of nursing at the Barts and the London Hospital Cancer Unit, asserted that too many people are being told to 'be positive' after a cancer diagnosis, when they need to be realistic and realise they will experience emotional lows. "I think that some people with cancer do come down with a bump when they realise that, for all their positive attitude, they haven't been cured," she said. 
    Dr Gerard Molloy, chair of the UK Society For Behavioural Medicine's scientific committee, said that while psychological traits such as optimism may be linked to longer survival from illness, there is no evidence that such traits can be cultivated by 'positive thinking'. "Remaining positive is sometimes harder than dealing with the chemo side effects and having cancer," he said.
