In Mangaldai, India, awareness of the UV Index is crucial for safeguarding your skin and overall health. Understanding the UV levels not only helps in preventing painful sunburns but also plays a significant role in reducing long-term skin damage, such as premature aging and skin cancer. With a Cwa climate, Mangaldai experiences high UV exposure, especially during peak hours, where the index reaches a maximum of 12 at noon.
