The sun primarily provides Vitamin D through its ultraviolet B (UVB) rays. Here’s a breakdown of how it benefits us:
1. **Vitamin D**: When your skin is exposed to UVB rays from the sun, it synthesizes Vitamin D. This vitamin is crucial for:
- **Bone Health**: It helps in the absorption of calcium and phosphorus, which are essential for maintaining healthy bones and teeth.
- **Immune Function**: Vitamin D plays a role in enhancing the immune system, which helps protect against certain diseases and infections.
- **Mood Regulation**: It may influence mood and help in the prevention of mood disorders such as depression.
While the sun is a major source of Vitamin D, it’s also possible to obtain this vitamin from dietary sources and supplements, especially in regions with limited sunlight.
