    Glossary Light Exposure

    amount of light received by an organism over time

    Light Exposure refers to the amount of light that an object or organism receives over a period of time. This can include natural sunlight or artificial light sources. In biological contexts, light exposure can significantly impact various physiological processes, such as circadian rhythms, skin health, and hair growth. For instance, excessive exposure to ultraviolet (UV) light can damage skin cells and hair follicles, potentially leading to conditions like alopecia.
