In acute inflammation, heating can do which of the following?

• A. Exacerbate inflammation
• B. Reduce inflammation
• C. Have no effect on inflammation
• D. Promote healing by reducing inflammation

Answer: (A)

In acute inflammation, applying heat tends to worsen the inflammatory response. The tissue is already undergoing vasodilation with increased blood flow and higher capillary permeability, which produces redness and warmth and promotes swelling. Introducing external heat boosts local blood flow even more and can expand edema by driving more fluid into the interstitial space. Heat also raises the metabolic activity of cells in the area, increasing oxygen demand; if the inflamed tissue is already compromised by limited oxygen, this extra demand can aggravate tissue injury and amplify the release of inflammatory mediators and pain signals. Because of these effects, heat is typically avoided in the early, acute phase to prevent escalating inflammation. It’s more appropriate later on, when the goal shifts to relieving stiffness or promoting healing, but not to reduce acute inflammation.
