Do you lose your temper or get irritated often? It’s high time that you try to become a cool dude. A new study has found that anger, which is known to blow out the light of reason, can delay healing too. A team of international researchers, led by the Ohio State University in Columbus, has found that being unable to control and vent anger can harm the process of healing a wound, The Daily Telegraph reported on Wednesday. In their study, the researchers analysed around 100 participants who had agreed to receive standardised blister wounds, inflicted by a vacuum pump on their non-dominant forearm. After blistering, the wounds were monitored daily for eight days to assess the speed of repair. The secretion of the stress hormone cortisol was also measured during blistering to evaluate the role of this hormone in the healing process. Taking into account potential confounding factors, people with low control over the expression of their anger were 4.2 times more likely to take more than four days to heal, compared to those with higher levels of anger control.
