Understanding the UV Index is crucial for residents of Huaiyang, China, where the sun's intensity can vary significantly throughout the day. With peaks reaching a notable 9 around midday, awareness of UV levels is essential not only for preventing painful sunburns but also for protecting long-term skin health.
