Understanding the UV Index is crucial for residents of Kahna Nau, Pakistan, where the climate often exposes individuals to varying UV levels throughout the day. With values soaring as high as 10, knowing how to interpret these readings is essential for effective sunburn prevention and maintaining skin health. As the sun rises, so do the risks associated with UV exposure, particularly during the peak hours from 10 AM to 2 PM.

Throughout the year, the UV Index exhibits significant seasonal changes, with the risk of harm from unprotected sun exposure notably increasing during the warmer months. From January with a UV Index of 4 (moderate) and a burn time of 30 minutes, the levels escalate, peaking in July and August at 11 (extreme), where burn time reduces to just 10 minutes. March through September presents very high UV Index levels, especially in April and May, demanding heightened sun safety measures.
