Anger is Also Good for Health
Many people choose to hold back their emotions when going through something unpleasant because they fear of being branded as a grumpy person. But a recent study found anger can be good for health.
Researchers from the University of Valencia in Spain were interested in what happens to the human body when they are angry. And these findings appear to support a general psychological theory that states that the ‘ventilation’ of emotions are better for mental health than to let it remain locked or buried.
The study found that expressing anger can increase blood flow to parts of the brain involved with happy feelings.
To conduct this study, researchers gathered 30 people in a lab, slowly increase the level of their anger and examined.
Heart rate, blood pressure and the two stress hormone levels of participants which is the testosterone and cortisol, were all measured. The brain is also screened, from the beginning to the end of the study.
The Finding that have been published in the Hormones and Behaviour journal, shows that the left side of the brain is more stimulated when the participants are angry.
” The left frontal brain region generally involves in positive emotions, while the right side associated with negative emotions,” said Dr. Herrero Neus, from the University of Valencia in Spain, who led the study, as reported by the Telegraph.
Dr Herrero also said that anger can drive major changes in the human body, that is controlling the work of the heart and hormones. He showed that cortisol levels decreased and increased testosterone levels.
In addition, there is a change in brain activity, especially in the frontal and temporal lobes.
However, this study found that anger can also have negative effects on the body, namely the participants’ blood pressure increased when they are angry.
