Awareness of the UV Index is crucial for residents and visitors of Shangdu, China, where the unique Dwb climate can lead to varying levels of sun exposure throughout the day. Understanding UV levels is essential not only for preventing sunburns but also for maintaining overall skin health in the long term.
