From a psychological perspective, stress is a complex phenomenon that involves the psychological, emotional, and physiological responses individuals experience when faced with challenging or demanding situations. It is a natural and adaptive reaction that prepares the body to cope with perceived threats or pressures. Stress is influenced by various factors, including individual perceptions, coping mechanisms, and the significance attached to the situation. While stress can motivate and enhance performance in certain instances, prolonged or excessive stress can have detrimental effects on mental and physical well-being. Psychological research has identified different types of stress, such as acute stress, chronic stress, and traumatic stress, each with unique characteristics and impacts. Psychologists employ various approaches to assess and manage stress, including cognitive-behavioral techniques, relaxation exercises, and stress reduction strategies. Understanding stress from a psychological viewpoint helps individuals recognize and develop effective coping strategies to mitigate its negative effects and promote overall resilience and well-being.
