Narcissistic men have higher levels of stress hormone

Narcissistic men have higher levels of stress hormone

Men who are narcissistic are likely to have higher levels of a primary stress hormone called cortisol, a new study finds.

However, the same trend was not as strong for women with narcissist traits, according to research published Monday in the journal Public Library of Science ONE.

“The more narcissistic, the more cortisol that men have in mundane situations,” said author Sara Konrath, who is the director of the Interdisciplinary Program on Empathy and Altruism Research at the University of Michigan.

Narcissism is a trait that exhibits “grandiosity, an inflated sense of self-importance, and over-estimations of uniqueness.”  If severe, it can also be a personality disorder recognized by the Diagnostic and Statistical Manual of Mental Disorders

The trait has some positive qualities, such as abundance of self-esteem and positive sense of self.  Narcissistic people characteristically tend to overestimate their intellectual abilities, attractiveness and positive personality traits, wrote Konrath.

But they don’t enjoy healthy relationships with others because they’re generally low on empathy and high in hostility – especially when their positive self-image is threatened. Since previous research confirmed that narcissism has a harmful effect on relationships, Konrath wanted to know more.

“I wondered if there’s harm going on, but it’s a harm we can’t articulate or recognize,” she said.

Narcissists aren’t likely to admit that they’re stressed or anxious.  So she needed an objective measure and decided to use cortisol levels to understand how narcissism could affect one’s health.

In the study, 106 undergraduate students (79 females, 27 males, mean age 20.1 years) from one Midwestern and one Southwestern American university took two cortisol tests and answered several questions about themselves.  They were unknowingly taking the Narcissistic Personality Inventory, which is used to assess people’s narcissism.

It gives statements like “I find it easy to manipulate people,” and “If I ruled the world it would be a better place," to which the respondent agrees or disagrees.

Konrath observed that men with higher levels of narcissism had more cortisol.  It was minimal in women, but about 2.5 times stronger in men.

Cortisol is a measurement of how prepared your body is ready to respond to a threat, said Konrath.  If the cortisol response is always high in the absence of a threat, it indicates an overactive response in the body.  This can have long-term health effects such as blood sugar imbalances, heart problems and weight gain.

The study could not determine why men appeared to be much more affected than women. But Konrath suggested that there could be overlaps between narcissism and male gender roles.

“We think what’s going on is, there’s some sort of especially toxic relationship between both being male and having a sense of masculinity or threat to a masculine identity.”

There could be a special vigilance for any threats that challenge their sense of toughness and competence,  she said.

      27 males in the study is a tiny sample size to warrant making any conclusions, much less a whole article on CNN. Come on CNN, this is crazy you would write an article on this study. Its all about the headline and getting readers, nothing about presenting any valid truth.

      Greg – most politicians are narcissists – Rep. and Dem. alike. Plus, everything is political when you really look at it. Also, AntiNarc – stop screaming about free-speech issues. CNN automatically flags certain words in posts not to censor ideas but for vulgarity issues and spam control. Every so often someone posts versions of those words when people are convinced CNN is personally certain ideas. Once you see them, you'd understand it has nothing to do with censorship.

      Narcissists deep down do have low self esteem. That's why they overcompensate. Narcissists have terrible skills dealing with anything negative, no wonder they are always so stressed out! They see everything that goes wrong as a personal attack and a slip in their control. They are rather pathetic and sorry individuals, but their lack of empathy toward others makes it very hard for anyone to feel sorry for them.

      Valerie and Sy-It seems to me like you are confusing low self-esteem with exaggerated self-image. In the eyes of the beholder, the narcissist is overcompensating, in the mind of the narcissist, he/she is just expressing "reality." True low self-esteem is more tied to depression, anxiety and social withdrawal than anything else. Methinks that perhaps your perceptions have been colored by frustrating relationships.

    Gingrich brings stress and distress to every conversation. He's bipolar and folks never know when his short fuze is at it's end. He's definitely a self-centered temeramental person (90% temper, 10% mental). It's also been rumored that he had mommy issues which may be why he has so many issues with women he can't buy. I'll quit telling the truth about him when he quits lying about the 99%.

    If you take away the hostility and insecurity, the narcissist would actually be a great personality. Grandiosity is a marvellous trait to behold, especially in such a humdrum and boring world. The focus then should be on getting rid of the irrational hostility towards others, that is the real problem, not self-love.

      Good luck trying to get rid of the hostility and insecurity! Because of the insecurity, these narcissists get so defensive and all hostility breaks loose, thus bringing out the irrational berating to those around them. Such a nightmare living with them. It is a shame, though, because they could go so far if they could keep their mouths shut.

    Narcissists are thought to feel shame where others feel guilt. That's got to add to the stress. Regardless, those suffering from acute narcissism are exceedingly poor company and a burden for their families.

    Wow, really? Narcissistic men have more cortisol......determined from a study of only 27 men?? There are well over 100 million men in this country and a conclusion like this can be made from studying 27 of them? Seriously? Study 27,000 men and the result will be much more realistic. And don't have them all be college students either because college students already have more stress anyway.

    My ex husband is narcissistic and since our divorce 6 years ago has gained about 50 pounds, now at 5' 9" and 250 pounds. He's developed heart and blood pressure problems that have him on several very strong medications. He's so overweight that he looks like he can barely get around and looks very unheatlhy. He's got few if any friends and can't accept that he's got a problem. If he would get help everything in his life, including his health, would be so much better. This study is right on target from what I've experienced.

    In reference to the article's subject matter, it must refer to narcissistic men without the power or social attention that they must need for self-confirmation, it seems that in a society like this one they would surely be very stressed. One thing is certain, they have a way of spreading that stress around among everybody else like typhus, empowered or not, and many parts of this country seems to be infested with them.

    Our narcissism is a result of the combination of 2 factors – our natural egoism and the reinforcement of this trait by our social environment. And it is growing worse. For example, studies show that current college students are more narcissistic and less empathetic than students in the 1970's.

    This narcissism is certainly not limited to men or to college students. We are all just a reflection of what our society values and teaches us. And society has placed an increasing emphasis on the self, self-centered goals, fame, and financial and personal success at any cost. The result? All the current crises – financial, social and environmental.

    The only way to solve these crises is to get to the heart of the problem. First, we each need to recognize the damage our egoism is doing, both to ourself and to the world, since everyone and everything is now so highly interconnected. Our ego constantly demands more and more for our self, but it can never be satisfied. It keeps us feeling isolated and prevents us from connecting with each other on a deep, emotional level.

    Second, we need to start building a society that encourages respect and caring for others. Just as we have been shaped by an environment that pushes us towards selfishness, we can reshape ourselves by creating an environment that encourages positive characteristics like empathy and understanding, and rewards actions that reflect those traits.
