Which of the following is a contraindication for heat therapy?

• A. Acute inflammation
• B. Controlled hypertension
• C. Infection
• D. Cardiac insufficiency

Answer: (A)

Heat therapy raises tissue temperature and promotes blood flow. In acute inflammation the tissue is already swollen, red, and actively inflamed with increased capillary permeability. Applying heat at this stage can worsen edema, amplify the inflammatory response, and increase pain, potentially delaying healing. That makes acute inflammation a clear contraindication for heat therapy. Controlled hypertension is not a blanket contraindication and may be used with caution in some cases. Infection is often avoided with heat because warmth can exacerbate symptoms in infected tissue and may encourage bacterial activity. Cardiac insufficiency can be a concern since the vasodilation from heat increases cardiac workload, but the defining contraindication among the options is the acute inflammatory state.
