Understanding the UV Index is crucial for the residents of Usehat, India, as it provides vital information about the strength of ultraviolet radiation from the sun, which can significantly impact your skin health. High UV levels, particularly during the mid-day hours, pose risks of sunburn and long-term skin damage, making it essential to stay informed. With Usehat's Cwa climate characterized by distinct wet and dry seasons, the sun's intensity can vary, but the potential for high UV exposure remains consistent, especially between 10 AM and 2 PM when the index peaks at levels of 11.
