Understanding the UV Index is essential for residents of Ashland, United States, where the climate's semi-arid conditions can lead to heightened sun exposure. Being aware of UV levels not only helps in preventing painful sunburns, but it also plays a crucial role in maintaining long-term skin health. With peak UV levels reaching as high as 9 around midday, it’s vital to stay informed and take precautions, especially during the warmer months.
