Understanding the UV Index is crucial for residents and visitors of Dushan, China, where sunny days are a hallmark of the Cfa climate. Recognizing and monitoring UV levels can significantly help in preventing sunburn and protecting skin health, making it essential knowledge for anyone spending time outdoors.
