This document discusses stress, how the body responds to stress, and strategies for managing stress. It explains that stress is the body's physiological and emotional response to stimuli that disturb homeostasis. The body's alarm phase in response to stressors triggers the sympathetic nervous system and hormones like cortisol. Over time, chronic stress can lead to illness if the body cannot recover. While short-term stress from important events can be helpful, long-term distress is harmful to health. The document recommends techniques for managing stress like exercise, social support, nutrition, sleep, and cognitive relaxation strategies.
