Do campfires put off UV light?

Yes, campfires do emit ultraviolet (UV) light, though the levels are relatively low compared to direct sunlight. Most of the UV radiation produced is in the UV-A range, which can contribute to skin damage over time. However, the intensity of UV light from a campfire is much less than that from the sun, so while some UV exposure occurs, it is not a significant risk compared to outdoor sun exposure.
