Michigan, freedom to express opinions is the right of all people. And you know, that dared to express an opinion is also good for your health.
When you experience tension with other people, good boss, wife or child, then you should be brave our opinion and your argument, because it avoids confrontation could be dangerous for health.
According to one study, it is associated with increased hormone cortisol, a hormone that triggers stress.
When someone away from a fight and did not dare to express an opinion, there will be an increase in abnormal hormone cortisol throughout the day.
"Dealing with other people has an important influence on our feelings every day, especially when there are problems in the relationship. The way we handle everyday problems greatly affect the health," said Kira Birditt, researchers from the Institute for Social Research at the University of Michigan, such as LiveScience quoted from Saturday (14/08/2010).
The results of this study were presented at the Annual Convention of the American Psychological Association-118 on 12 August.
In the study, researchers wanted to know the health effects of avoidance behavior and did not dare express an opinion.
"People who tend to avoid the conflict did not show physical symptoms directly, but this would be associated with abnormal physical symptoms long term," said Birditt.
People who avoid tension and do not dare to express an opinion, will experience a sharp increase in the hormone cortisol and the reduction will be very slow. Increased hormone cortisol is what can cause long-term abnormal physical symptoms.
Cortisol in small doses can actually be a positive effect on the body, which increases alertness and useful in regulating blood sugar.
But this hormone is always increased when she was frustrated, so called 'stress hormones'. And if there is a sharp increase in hormones, it can adversely affect health.
Increased hormone cortisol is associated with cardiovascular disease and blood vessels. In other words, people who do not dare to express an opinion are more susceptible to heart disease and stroke.
Not only that, the increase in the hormone cortisol is also associated with diabetes, high blood pressure (hypertension) and impotence for men.
