In Lishu, China, being aware of the UV Index is crucial for maintaining skin health and preventing sunburn. Understanding UV levels helps residents and visitors alike make informed decisions about sun exposure, especially during the peak hours when the risk of harm is highest. With a Cwa climate, Lishu experiences significant UV exposure, particularly between 11:00 AM and 1:00 PM, when the UV Index can soar to a maximum of 12. Staying vigilant about UV levels not only protects your skin from short-term damage but also reduces the risk of long-term health issues.
