Understanding the UV Index is vital for residents and visitors in Chunwan, China, where the sun's rays can pose significant health risks, particularly during the peak hours of exposure. With UV levels often soaring, especially between 11:00 AM and 1:00 PM, it's crucial to be aware of how to protect your skin from harmful effects like sunburn and long-term damage. Chunwan’s humid subtropical climate contributes to a high UV Index, making it essential for everyone to monitor daily UV levels and adopt appropriate sun safety measures.
