Sonnenlicht, or sunlight, is the natural light that comes from the Sun. It is essential for life on Earth, providing energy for plants through the process of photosynthesis. Sunlight also helps regulate the Earth's climate and supports various ecosystems. In addition to its ecological importance, Sonnenlicht has various effects on human health. Exposure to sunlight helps the body produce vitamin D, which is crucial for bone health. However, too much sunlight can lead to skin damage and increase the risk of skin cancer, making it important to balance sun exposure.
