It’s not healthy to be hostile, according to a recent study from Duke University.
Steven Boyle, Ph.D., a researcher at Duke University Medical Center, says men who regularly exhibit strong feelings of anger or depression may face increased risk of coronary heart disease.
The study was conducted on 313 men who were given a standard psychological test that measures hostility, anger and depression.
Men whose psychological screening showed the highest level of hostility, depressive symptoms and anger had a 7.1 percent increase in levels of an immunity protein known as C3, while men with lower levels of hostility, depression and anger showed no during the decade-long study.
According to the study’s co-author, Edward Suarez, Ph.D., the lifestyle of individuals with a hostile attitude, "often leads to greater stress and possibly changes in the way the body functions that could lead to disease.”
The study appears in the August issue of the journal Brain, Behavior, and Immunity.
