Sunlight exposure refers to the amount of solar radiation that reaches the Earth's surface. This radiation includes visible light, ultraviolet (UV) light, and infrared radiation. Sunlight is essential for various processes, such as photosynthesis in plants, which converts light energy into chemical energy, supporting life on Earth. While sunlight is beneficial, excessive exposure can lead to harmful effects, such as skin damage and increased risk of skin cancer. The intensity of sunlight varies based on factors like time of day, season, and geographic location. Proper protection, such as using sunscreen or wearing protective clothing, can help mitigate these risks.
