What are UV levels and how can you protect yourself?
Ultraviolet (UV) radiation from the sun can be both beneficial and harmful. While it helps produce vitamin D, excessive exposure increases the risk of skin cancer and other health issues. Understanding UV levels and taking protective measures is essential for skin health.
- ▪UV radiation is essential for vitamin D production but can cause skin damage and increase cancer risk.
