Understanding the UV Index is crucial for residents of Dumka, India, as it provides essential insights into the levels of ultraviolet radiation you're exposed to throughout the day. With peaks reaching a high of 12 around noon, awareness of UV levels can help you take preventive measures against sunburn and protect your skin health.
