The present paper makes a research about negative effects of anger and hostile conduct on peoples' health status. We have studied scientific articles published between 2000 and 2010, which did not contradict our initial assumption. The literature demonstrates that anger, wheatear suppressed or expressed, can determine various diseases, it can influence the conduct of people suffering from bulimia nervosa or it can be the cause for the growing number of car accidents. In order to avoid these risks, the intervention should not be limited to medication, but it should also involve a psychological help that should insist on ways of dealing with anger without exposing the person to any kind of risk for his health or wellbeing.
