[Singh P (2026); evidence level 2] - This environmental shift may have consequences beyond vitamin D synthesis; emerging evidence suggests that NIR radiation interacts directly with mitochondrial chromophores, potentially serving as a physiological stimulus for endogenous protective mechanisms [,]. [Muacevic Alexander (2026); evidence level 3] - However, whether reduced NIR exposure in modern populations contributes to increased neurodegeneration remains speculative and has not been directly tested epidemiologically. [Muacevic Alexander (2026); evidence level 3] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
