High UV index poses health risks in Kerala

Kerala has been experiencing high levels of ultraviolet radiation, raising health concerns among residents. The Kerala State Disaster Management Authority reported a UV index of 12 in Munnar and 11 in Konni on March 17. Other areas recorded lower but still concerning levels, such as Kottarakkara with 10 and Ponnani with 9. The UV index measures sun radiation on a scale of 1 to 11. A level of 11 or higher requires a purple alert due to extreme health risks. Levels between 8 and 10 call for a red alert, while 6 and 7 trigger an orange alert suggesting precautions. Experts warn that high UV exposure can lead to skin issues like premature aging, sunburn, and, in the long term, skin cancer. Dr. T. Jayakrishnan, a public health expert, explained that UV rays can harm both skin and eyes. UVA rays penetrate deeper, while UVB rays mainly cause sunburn. Prolonged exposure might damage the retina, particularly in children, potentially leading to painful eye conditions. A recent study noted that over 79% of UV measurements in Kerala from 2004 to 2022 fell into very high or extreme categories. These extremes are more common during certain months, with increased UV levels recorded in March, April, and September. To protect themselves, experts suggest wearing sunglasses and using hats or UV-protected umbrellas. Those working near water or on construction sites should take extra precautions. While sunscreen may be less critical for darker-skinned individuals due to natural melanin protection, vigilance is essential for everyone during high UV index periods.
