Even if light cannot directly reach a target area (e.g., a broken arm in a cast), biological benefits can still occur through secondary mechanisms: light absorbed elsewhere triggers vasodilation, increased blood flow, increased oxygen delivery, increased lymphatic flow, gene transcription, angiogenesis (new capillary formation), and stem cell differentiation, which collectively benefit tissues beyond the directly illuminated area.

“just because the light does not directly reach the area of concern doesn't mean there aren't biological changes occurring... vasodilation increased blood flow increased oxygen increased lymphatic flow Gene transcription... angiogenesis... stem cell differentiation all of these primary and secondary actions affect not just the immediate area but can greatly affect and benefit tissue on the opposite side of the body”
