Actually, everything with a temperature above 0 Kelvin emits light. But our glow is not just from body heat—the amount of light and the amount of heat we give off do not match, meaning we truly are slightly bioluminescent. Scientists found that we give off light in a 24-hour cycle, and that the brightest light comes from our cheeks, forehead, and neck.
