Understanding the UV Index is crucial for residents and visitors of Songjianghe, China, where the climate can expose individuals to potentially harmful levels of ultraviolet radiation. With UV Index values peaking at 11 during midday hours, awareness of these levels is essential for sunburn prevention and maintaining skin health.

High-risk months for UV exposure are April to July, with July being particularly concerning due to its extreme UV Index of 11, which requires minimal exposure time of only 10 minutes to risk skin burns. In contrast, January and December report a low UV Index of 2, allowing for longer safe exposure times of up to 45 minutes. To minimize skin damage, residents and visitors should take precautions during the high-index months, especially by wearing sunblock, protective clothing, and seeking shade when necessary.
