The acute stress response, a physiological reaction to perceived harm or threat, involves a cascade of hormonal and neurological changes preparing the body for either confronting the danger or escaping it. This response can be assessed through various methods, including measuring heart rate, blood pressure, and cortisol levels. For example, a sudden loud noise might trigger this response, leading to increased heart rate and muscle tension.
Understanding this primal survival mechanism is crucial for managing stress and its impact on health. Recognizing the physiological signs and triggers allows individuals to develop coping strategies and potentially mitigate the negative consequences of chronic stress. This biological response has ancient evolutionary roots, ensuring the survival of humans and other mammals in dangerous environments. It enables rapid decision-making and physical preparedness in the face of perceived threats.
