Effective protection against UVB rays involves a combination of behavioral and protective measures. Limiting sun exposure during peak UV hours, typically between 10 a.m. and 4 p.m., is recommended. Wearing protective clothing, hats, and sunglasses can also reduce UV exposure. The application of broad-spectrum sunscreens with a high SPF can provide a chemical barrier that absorbs or reflects UVB rays, preventing them from penetrating the skin.
