Anger is a normal human emotion that arises in response to frustrating or difficult situations. There are three main types of anger: passive-aggressive, assertive, and openly aggressive. Anger triggers vary between individuals but common ones include stress, disappointment, insults, and fears. If left unmanaged, anger can negatively impact physical health and relationships. Effective anger management involves identifying triggers, learning healthy expression techniques like meditation, and recognizing when professional help is needed.
