The UV index is not the warm sensation of sunlight on bare skin
This trending item is a blog post explaining a common misconception: the UV index measures the strength of ultraviolet radiation that causes sunburn and skin damage, not the warmth you feel from sunlight. That warm sensation comes mostly from infrared radiation, which is separate from UV. Readers on Hacker News appear to be sharing and discussing the post, apparently finding it a useful correction of a widespread misunderstanding about what the index actually tracks.
Why now: Readers found the post's counterintuitive clarification about what the UV index actually measures worth discussing and upvoting.
