Abstract: System and methods to generate and control light for use in therapeutic, aesthetic, disinfection, and other light-related applications in settings where a significant portion of skin is exposed to light (e.g., shower, sauna, locker-room). Characteristics of the light are controlled to simulate specific spectra of natural sunlight and unnatural light and deliver targeted doses of UV light (e.g., for vitamin-D synthesis, boosting the immune system, tanning), UV-C light (e.g., to kill bacteria, viruses, and fungi), visible light (e.g., to anchor a circadian rhythm to improve mood, metabolism, cognitive functions, physical performance, and sleep), and red or infrared light (e.g., for skin rejuvenation, wound healing, tissue repair, blood-flow, muscle recovery, circulation) while, at the same time, minimizing negative impacts of light exposure. Various embodiments may further create the experience of an outdoor shower.
