Which physiological measure is commonly monitored using biofeedback?

The most commonly monitored physiological measure using biofeedback is skin conductance. This measure reflects the electrical conductance of the skin, which changes with the level of sweat gland activity. Skin conductance is often used to assess autonomic nervous system responses, particularly in relation to stress and arousal. It provides a direct measure of emotional and physiological responses, making it valuable for biofeedback training aimed at enhancing self-regulation and awareness.

While heart rate variability, muscle strength, and breath rate are also important physiological measures that can be monitored, they serve different purposes and may not be as widely utilized in biofeedback settings as skin conductance. Heart rate variability is crucial for understanding respiratory and cardiovascular health, muscle strength is related to physical rehabilitation, and breath rate is associated with respiratory control and relaxation techniques. Thus, skin conductance stands out as a key metric for biofeedback applications focusing on emotional and stress responses.
