Vanity can be deadly for men: study

Men with an inflated view of their own brilliance might look like they breeze through life in a bubble of confidence. But in reality, they're likely to be so plagued by worry they put their health at risk, according to a study.

It found narcissism, or self-love, is on the rise in men and is causing them to suffer stress-related illnesses like high blood pressure, which can lead to heart disease.

Psychologists asked 106 men and women to take personality questionnaires and took two saliva samples from them to measure levels of cortisol, a stress-related hormone.
Men who showed "unhealthy" levels of narcissism in the survey also had high levels of cortisol, even in a relaxed situation. In women, this was not the case.

The study's authors say the reasons are unclear, but suggest the pressure to fulfil traditional male traits, like strength and dominance, may be taking its toll.

"Even though narcissists have grandiose self-perceptions, they also have fragile views of themselves, and often resort to defensive strategies like aggression when their sense of superiority is threatened," says co-author David Reinhard of the University of Michigan.

"These kinds of coping strategies are linked with increased cardiovascular reactivity to stress and higher blood pressure, so it makes sense that higher levels of maladaptive narcissism would contribute to highly reactive stress response systems and chronically elevated levels of stress."

The scientists defined narcissism as "an inflated sense of self importance, overestimation of uniqueness, and a sense of grandiosity".

While a "healthy" degree of narcissism is good for you, they say, too much can cause tension and in extreme cases lead to depression and personality disorders.

There was no relationship between healthy narcissism and cortisol in either the men or women.

But the researchers say an unhealthy form of the personality trait, reflected in exploitativeness and a sense of entitlement, appears to "chronically over-activate" the body's "HPA axis" or "stress circuit".

Signals from the brain trigger the release of hormones including cortisol from glands associated with energy expenditure, the immune system and mood change. Many anti-depressant drugs work by inhibiting activity in the HPA axis.
This work supports previous studies that have shown that while narcissistic people think they are happy and have high self-esteem, many actually display characteristics associated with unhappiness and insecurity.

The authors are not sure why this effect is not seen in women, but suggest they may conform to social stereotypes to value relationships and seek the support of others to a greater extent than men.

Professor Sara Konrath, lead author of the study, which was published in the journal PLoS ONE, said: "Narcissistic men may be paying a high price in terms of their physical health, in addition to the psychological cost to their relationships."

"Our findings suggest the HPA axis may be chronically activated in males high in unhealthy narcissism, even without an explicit stressor."

Prof Konrath hopes to conduct further research examining why narcissism is not as physiologically taxing for women.
