Stress physiology is a branch of science that studies how the body responds to stressors, or any external factors that disrupt the body's normal equilibrium. This field examines the physiological changes that occur in the body in response to stress, including the release of stress hormones such as cortisol and adrenaline, changes in heart rate and blood pressure, and alterations in the immune system and metabolic processes. Researchers in stress physiology seek to understand the mechanisms behind these responses and the impact of chronic stress on overall health and well-being. Studies in this area often focus on identifying strategies to mitigate the negative effects of stress on the body.
