What technique modifies physiological processes like heart rate and body temperature?

The correct answer is biofeedback, which is a technique that enables individuals to gain awareness and control over certain physiological functions typically considered involuntary, such as heart rate and body temperature. Through biofeedback, individuals receive real-time feedback from monitoring devices that measure bodily functions. This information can then be used to learn how to consciously influence these physiological processes.

For instance, someone might use biofeedback to see their heart rate and learn strategies to lower it through relaxation techniques or controlled breathing. This process shows the connection between mind and body and emphasizes the potential for self-regulation in managing stress and improving health.

In contrast, while hypnosis can induce a state of focused attention and relaxation, it does not specifically modify physiological processes in the same direct and measurable manner as biofeedback. Meditation can lead to relaxation and reduce stress, but does not inherently provide the real-time feedback needed to modify physiological processes. Relaxation therapy may help in managing stress-related symptoms, but it also lacks the specific mechanisms of feedback provided by biofeedback, which helps individuals actively learn to control their physiological responses.
