Psychophysiological processes refer to the interactions between psychological factors and physiological responses in the body. These processes illustrate how emotions, thoughts, and behaviors can influence physical health. For example, stress can trigger the fight-or-flight response, leading to increased heart rate and blood pressure. Research in this field often examines how mental states, such as anxiety or depression, can affect bodily functions. Techniques like biofeedback are used to help individuals gain awareness and control over their physiological responses, promoting better health and well-being. Understanding these processes is essential for fields like psychology and medicine.
