Stress Physiology

Stress physiology refers to the body's response to perceived threats or challenges, known as stressors. When faced with stress, the brain signals the release of hormones like adrenaline and cortisol. This activates the "fight or flight" response, preparing the body to respond quickly—heart rate increases, breathing quickens, and energy is mobilized. While this response can be beneficial in short bursts, chronic stress can lead to health issues, including anxiety, cardiovascular problems, and weakened immunity. Understanding this process helps highlight the importance of managing stress for overall well-being.
