Anger is a basic human emotion that varies in intensity and can lead to issues if excessive. It is normal to feel anger when treated unfairly, opposed in views, or facing challenges to goals. Chronic anger can cause physical harms like heart disease and mental health issues by consuming brain energy. While some anger can be healthy, excessive anger should be managed through techniques like deep breathing, exercise, avoiding triggers, and practicing forgiveness. Proper sleep, nutrition, and stress management can also help avoid anger issues.
