Understanding the UV Index is vital for residents of Chahayang, China, where sun exposure can vary significantly throughout the day. With a climate characterized by cold winters and hot summers, the risks of sunburn and long-term skin damage are heightened. This makes it essential to monitor UV levels to protect your skin health. During peak hours, especially between 10 AM and 2 PM, UV Index values soar to 8, indicating a very high risk of harm from unprotected sun exposure. Staying informed about these levels not only helps in preventing immediate discomfort from sunburn but also supports long-term skin health in this sun-rich environment.
Between 07:00 and 14:00, the UV Index reaches its peak, starting at a moderate 2 and climbing steadily to a sizzling 8 by 11:00 and maintaining that intensity through 13:00. As the sun begins to descend, the UV levels dip to 6 at 14:00, gradually tapering off to 5 at 15:00, then further declining to 3 at 16:00. By the time 17:00 rolls around, the index has dropped back to 2, and soon after, it plummets to 1 for the evening hours, emphasizing the importance of sun protection during the midday peak times. Make sure to enjoy the sunshine safely!

The UV Index exhibits distinct seasonal changes, with high-risk months occurring from April to August, when the index reaches very high levels of 8, indicating a significantly increased potential for skin damage. During these months, the recommended burn time is as short as 15 minutes, necessitating heightened caution. In contrast, from January to March and in November and December, the index remains relatively low (between 1 and 2), offering longer burn times of 45 minutes, suggesting lower UV exposure risk. Residents and visitors are advised to take preventative measures during the high-index months, such as applying sunscreen, wearing protective clothing, and seeking shade during peak hours to mitigate risks of sunburn and other UV-related health issues.
