In Dongshan, China, understanding the UV Index is crucial for safeguarding your skin against sun damage. With varying levels of ultraviolet radiation throughout the day, awareness of these UV levels can help prevent painful sunburns and promote overall skin health. As a Cfa climate zone, Dongshan experiences hot summers and mild winters, leading to increased exposure risks, especially during peak hours when the UV Index reaches a maximum of 10. By staying informed about UV levels, residents and visitors can enjoy the sun safely while protecting their skin from harmful rays.
