Psychophysiology is a branch of psychology that focuses on the relationship between the mind and body. It involves studying how psychological processes, such as emotions, thoughts, and behaviors, impact physiological responses in the body, such as heart rate, blood pressure, and hormone levels. This field seeks to understand the connection between mental and physical health and how the two interact to influence overall well-being. Research in psychophysiology often involves techniques such as measuring brain activity, heart rate variability, and skin conductance to explore the mind-body connection in various contexts, such as stress, emotion regulation, and mental health disorders.
