Why You Should Take It Easy?

Many management experts believe personality plays an important role in career advancement. For one to excel, he or she has to be confrontational, especially competitive and even aggressive. However, if you belong to this class of people, perhaps, you should take it easy from now onwards.

This is because a study by researchers from the National Institute on Aging (NIA) found that these types of people are at a higher risk of heart attack and stroke. Their findings were published on August 16, 2010 in ‘Hypertension’, Journal Of The American Heart Association (AHA).

5,614 residents, aged between 14 and 94 (on average 42), of 4 villages in the Italian Mediterranean island of Sardinia were examined. 58 percent of the residents were female.

The participants were asked to fill in a questionnaire that was a modified version of the NEO, a popular five-factor personality assessment questionnaire. People who marked themselves as aggressive on the questionnaire were at a higher risk to suffer from thickening of the neck arteries than those who were marked as affable or accommodating.

3 years later, those who scored higher on antagonism, especially those who were manipulative and expressed anger quickly, continued to have thickening of their artery walls. And for people who were the most antagonistic, the chance that they would get thicker arteries were about 40 percent higher.

Ultrasound technology (non-invasive ultrasonography) was utilized to measure arterial wall thickening, which is a sign of ageing that could predict future cardiovascular disease. It is known as intima-mediat thickness (IMT), a predictor for heart attack and stroke. The measurements taken in the study were on participants’ IMTs of the carotid artery, which supplies most of the blood to the brain, were measured.

According to the researchers, people who had high score on antagonism tend to be distrustful, skeptical and at the extreme arrogant, cynical, express anger quickly, manipulative, and self-centered, while people who are agreeable tend to be trusting, straightforward and care for others.

The new finding undoubtedly supports the fact that negative psychological factors do have a great impact on a person’s health as much as lifestyle and smoking.
