When gentle heat is applied to the body, it helps widen blood vessels, allowing more oxygen and nutrients to reach sore or stiff areas. This increased blood flow can help muscles relax, reduce stiffness, and ease discomfort. Heat also helps calm pain signals sent from the affected area to the brain, which may reduce the feeling of pain.

The built-in massage and vibration therapy works together with heat to gently stimulate muscles and surrounding tissues. This stimulation helps loosen tight muscles, improve circulation, and support relaxation. Vibration can also encourage the nervous system to release tension, helping the body feel more at ease.
