The UV Index is a scale that measures the strength of ultraviolet (UV) radiation from the sun. It helps people understand how much sun exposure is safe and when to take precautions. The index ranges from 0 to 11+, with higher values indicating a greater risk of harm from unprotected sun exposure. For example, a UV Index of 0-2 means low risk, while a value of 8-10 suggests very high risk. To protect yourself from harmful UV rays, you can use sunscreen, wear protective clothing, and seek shade during peak sun hours. The UV Index is especially important for outdoor activities, as it helps you enjoy the sun safely while minimizing the risk of skin damage and other health issues.
