Thiruvananthapuram, 18 Feb (H.S.):The Kerala State Disaster Management Authority (KSDMA) has issued a yellow alert in seven regions across the State after elevated levels of ultraviolet (UV) radiation were recorded over the past 24 hours. The alert has been declared for Kottarakkara, Konni, Chengannur, Changanassery, Munnar, Thrithala and Mananthavady, where the UV index ranged between 6 and 7.
Konni and Munnar reported the highest UV index of 7, prompting authorities to urge residents to exercise caution. Areas with a UV index between 6 and 7 fall under the “yellow alert” category, indicating a high risk of harm from unprotected sun exposure.
According to the KSDMA, prolonged exposure to ultraviolet rays can lead to sunburn, skin disorders, eye damage and other health complications. The authority has advised the public to take adequate safety precautions, particularly during peak hours when UV radiation is at its strongest.
The highest UV levels are typically recorded between 10 a.m. and 3 p.m. Officials have recommended that people avoid direct exposure to sunlight during these hours as far as possible. Those engaged in outdoor occupations and activities are especially vulnerable.
The advisory specifically calls for heightened caution among outdoor workers, fishermen involved in coastal and inland fishing, individuals engaged in water transport, motorcyclists, tourists, and people with pre-existing skin or eye conditions. Cancer patients and individuals with weakened immune systems have also been advised to limit sun exposure and follow protective measures.
Residents stepping out during the daytime are encouraged to use protective gear such as hats, umbrellas and sunglasses. Wearing full-coverage cotton clothing is recommended to reduce direct skin exposure. Authorities have also advised taking regular breaks in shaded areas during travel or outdoor work.
The KSDMA noted that UV levels tend to be higher in hilly and tropical regions. Even on days with clear skies and no visible cloud cover, UV radiation can remain intense. Additionally, surfaces such as water bodies and sand can reflect ultraviolet rays, increasing exposure risks in coastal and open areas.
Officials have reiterated that public awareness and precautionary steps are crucial to preventing health issues associated with high UV radiation.
