Thiruvananthapuram, 05 March (H.S.):Ultraviolet (UV) radiation levels have increased across several parts of Kerala, prompting the State Disaster Management Authority to issue alerts in multiple districts. According to the latest assessment, the highest UV index over the past 24 hours was recorded in Munnar in Idukki district and Konni in Pathanamthitta district, where the UV index touched 8. In response, authorities have issued an Orange Alert in these regions and urged the public to exercise caution.

Several other areas in the State have been placed under a Yellow Alert following moderately high UV radiation readings. These include Kottarakkara in Kollam district, Chengannur in Alappuzha, Changanassery in Kottayam, Kalamassery in Ernakulam, Ollur in Thrissur, Thrithala in Palakkad, Ponnani in Malappuram, Beypore in Kozhikode, and Mananthavady in Wayanad.

Health experts and disaster management officials have warned that prolonged exposure to ultraviolet radiation can lead to serious health issues. Continuous exposure to high levels of UV rays may cause sunburn, skin diseases, eye-related ailments, and other health complications. The UV index scale is used to measure the intensity of ultraviolet radiation. A Yellow Alert is issued when the UV index ranges from 6 to 7, while an Orange Alert is declared when it reaches between 8 and 10. A Red Alert will be issued if the UV index rises above 11, indicating extremely dangerous exposure levels.

Authorities noted that the UV index is typically at its highest between 10 a.m. and 3 p.m. Residents have therefore been advised to avoid prolonged exposure to direct sunlight during these hours as much as possible.

People engaged in outdoor work are particularly vulnerable. This includes fishermen operating both in the sea and inland waters, individuals involved in water transport services, construction workers, bike riders, and tourists visiting open areas. Special caution has also been advised for people with skin conditions, eye diseases, cancer patients, and individuals with weakened immune systems.

The Disaster Management Authority has recommended several precautionary measures. People stepping outdoors during the daytime should use protective gear such as hats, umbrellas, and sunglasses. Wearing loose, full-sleeved cotton clothing that covers most parts of the body is also advised to reduce direct exposure to harmful rays.

Travellers and workers are also encouraged to take frequent breaks in shaded areas during long periods outdoors. Authorities pointed out that mountainous regions and tropical zones typically experience higher UV index levels, and residents in these areas should remain particularly vigilant.
