Anger is an emotional state that varies in intensity from mild irritation to intense fury and rage. When angry, the body undergoes physiological changes like increased heart rate and blood pressure. Anger can be triggered by both external events like traffic or personal problems, as well as internal thoughts and memories. There are several ways to manage anger, including assertive expression, suppressing/redirecting feelings, and calming oneself physically and cognitively. Learning to identify triggers and employ relaxation techniques can help reduce anger and its physiological symptoms over time.
