The primary effect of radiant energy on tissue is

Explanation:
Radiant energy primarily acts as a heat source for tissues. When infrared or other radiant energy is applied, it is absorbed by the skin and underlying tissues, raising the local temperature. This temperature rise is the main tissue-level change, leading to vasodilation and increased blood flow, higher metabolic activity in cells, and greater extensibility of soft tissues. These thermal effects are the immediate, direct impact of radiant energy on tissue. Pain relief, increased circulation seen as a result, and reduction in muscle spasm can occur as consequences of heating, but they are secondary to the primary thermal effect.
