In Yatou, China, staying informed about the UV Index is crucial for safeguarding your skin and overall health. Understanding UV levels can help residents and visitors alike prevent sunburn and long-term skin damage, especially given the region's Cwa climate, characterized by distinct seasons and varying UV exposure risks throughout the year.
