Healing with Light

Ancient practices, like those of the Egyptians, hint at the profound impact of light on health. Florence observed that natural light significantly aided healing in hospitals, a finding echoed by Niels, who discovered ultraviolet light's antibacterial properties and the healing effects of red and infrared light. This led to the development of Heliotherapy, which was utilized during World War I to accelerate wound healing and combat diseases like rickets in children deprived of sunlight.
