Understanding the UV Index in Sanchuan, China, is crucial for maintaining skin health and preventing sunburn, especially during the peak summer months when UV exposure is at its highest. With UV levels peaking at 14 around noon, residents and visitors alike must remain vigilant to safeguard their skin from harmful rays.
