Stress can be caused by both physiological and psychological stressors. The body responds to stress through the release of stress hormones and physical adaptations. Prolonged stress can lead to exhaustion. Psychological responses to stress include feelings of depression, anxiety, frustration and irritability. Personality traits like optimism can act as a buffer against stress while traits like anger and hostility increase health risks like cardiovascular disease. Coping strategies like problem-focused coping, emotion-focused coping and social support can help manage stress.
