Anger is an emotion characterized by antagonism toward someone or something you feel has deliberately done you wrong.
Anger can be a good thing. It can give you a way to express negative feelings, for example, or motivate you to find solutions to problems.
But excessive anger can cause problems. Most people get angry at least a few times a week. That’s perfectly normal, what’s not, is intense anger that happens more frequently and lasts longer than the brief irritation most of us occasionally feel. Other warning signs include physical aggression, nasty responses and problems with your relationships, health or job as a result of your temper. Increased blood pressure and other physical changes associated with anger make it difficult to think straight and may harm your health.
