Anger is a normal human emotion that is triggered by feelings of hurt, mistreatment, or obstacles preventing goal attainment. While anger itself is natural, uncontrolled anger can be problematic and negatively impact relationships. The body's reaction to anger involves increased heart rate, blood pressure, and muscle tension. Unmanaged anger may lead to health issues, accidents, interpersonal problems, and potentially criminal behavior. Learning to identify anger triggers and express anger in an assertive rather than passive-aggressive or openly aggressive manner can help manage anger effectively.
