What therapy involves monitoring physical behaviors like blood pressure and muscle tension?

Relaxation therapy involves techniques aimed at reducing physical tension and promoting relaxation. This approach often includes monitoring physiological responses such as blood pressure and muscle tension, allowing individuals to become more aware of their body’s responses to stress and effectively practice relaxation skills. By focusing on these physical behaviors, practitioners can guide clients in achieving a state of relaxation that counters the body's stress responses.

In the context of other therapies, cognitive restructuring focuses on changing maladaptive thought patterns, while imaginal and in vivo exposure are techniques used to confront feared situations or stimuli. Neither of these approaches specifically targets the monitoring of physical behaviors related to relaxation and tension reduction, making relaxation therapy the most relevant option for this question.
