Stress can be caused by external pressures from the environment or internally. It is neither good nor bad, but a natural response to demands placed on us. There are three main types of stress: acute, episodic, and chronic. Signs of stress include sweating, nausea, and irritability. If not managed, stress can lead to issues like anxiety, depression, heart disease, and skin problems. Effective stress management tools include exercise, sleep, hobbies, and meditation. Therapy, religion, and nature can also help reduce stress. Modern life brings additional stressors such as financial issues, work pressures, and relationship challenges. Learning to prioritize and set boundaries can help manage stress from these sources.
