Understanding the UV Index is crucial for residents of Houzhen, China, where the combination of a Cwa climate and high sun exposure can lead to increased risks of skin damage. The UV Index indicates the intensity of ultraviolet radiation, and being aware of these levels can help you prevent sunburn and protect your skin health. With midday peaks reaching a significant level of 9, it's essential to take precautions, especially during the summer months when the sun is at its strongest. Stay informed, adapt your outdoor activities, and ensure your skin stays safe under the sun's rays.
Throughout the day, the UV Index experienced a dynamic rise and fall, peaking at 9 between 11:00 AM and 12:00 PM, indicating a heightened risk of harm from unprotected sun exposure.
