Which statement best describes thermotherapy?

• A. A therapy that constricts blood vessels to reduce blood flow.
• B. A therapy modality that dilates blood vessels, increasing circulation and relieving pain.
• C. It uses electrical stimulation to relax muscles.
• D. A therapy modality that reduces metabolism through cold exposure.

Answer: (B)

Thermotherapy heats tissues to raise their temperature and promote healing. The best description is that it dilates blood vessels, increasing circulation and relieving pain. When heat is applied, blood vessels expand (vasodilation), which brings more oxygen and nutrients to tissues, helps remove waste products, reduces muscle guarding and spasm, and can improve joint mobility. This is why warmth often relaxes the body and eases soreness. Common ways to apply thermotherapy include warm towels, heating pads, warm baths, or paraffin wax. Use for short periods (about 15–20 minutes) and check the skin to avoid burns. Avoid thermotherapy in acute injuries with active swelling, when there’s impaired sensation, or on areas with active bleeding or open wounds. Other statements describe cooling to constrict vessels, electrical stimulation, or cooling to reduce metabolism, which are different modalities and not thermotherapy.
