Natural sunlight is the light that comes from the Sun, which is a star located at the center of our solar system. This light is essential for life on Earth, as it provides energy for plants through the process of photosynthesis. Sunlight also helps regulate the climate and supports various ecosystems. Sunlight consists of different wavelengths, including visible light, ultraviolet (UV) rays, and infrared radiation. It travels through space and reaches Earth in about 8 minutes. Exposure to natural sunlight can have positive effects on human health, such as boosting mood and providing vitamin D.
