What is the rationale to “implement non-pharmacological interventions such as relaxation exercises,…

➤ How do specific techniques—relaxation, guided imagery, heat, and cold—actually reduce pain?
Progressive muscle relaxation and diaphragmatic breathing lower autonomic arousal and muscle spasm, easing nociceptive signalling. Guided imagery shifts attention and evokes calming sensory images, engaging descending inhibition and releasing endorphins. Heat relaxes tissues and increases perfusion; cold reduces swelling and slows nociceptors. Use short sessions and track pain scores.
