Why is the temperature increased to 41-44 degrees on thermal therapy (TCM)?

• A. It sterilizes the equipment
• B. It improves capillary blood flow and enhances gas movement through the skin
• C. It reduces metabolic rate
• D. It increases brain perfusion

Answer: (B)

Heating to 41–44°C in thermal therapy raises the tissue temperature enough to cause vasodilation of the skin’s blood vessels, which increases capillary blood flow. That greater perfusion brings more oxygen to tissues and helps remove carbon dioxide, improving overall gas exchange. The higher temperature also boosts the rate of gas diffusion across tissue and skin, making it easier for gases to move between the blood and surrounding tissues. These effects are why the goal is to enhance capillary perfusion and gas movement through the skin. Sterilization isn’t achieved by this heating level, metabolic rate doesn’t decrease (in fact it can rise with heat), and while brain perfusion can increase with systemic warming, that isn’t the primary objective here.
