Stress is caused by our emotional and physical response to pressure from the outside world. While a little stress can add excitement to life, too much stress can harm health and relationships. Stress causes both mental symptoms like tension and irritability, as well as physical symptoms like headaches and tight muscles. Many addictions are linked to using substances like food, smoking, drinking, or drugs to temporarily relieve stress, but these behaviors can actually make health problems worse or increase risks of heart attacks and strokes. Managing stress through humor, hobbies, and relaxing activities like watching a funny movie or gardening can help people reduce stress in a healthy way.
