Ultraviolet (UV) radiation levels have surged across Kerala, prompting the Kerala State Disaster Management Authority (KSDMA) to issue an orange alert across six districts and caution residents against prolonged exposure to direct sunlight amid rising health risks.

According to official data released on Thursday, districts including Pathanamthitta, Alappuzha, Kottayam, Idukki, Kollam, and Palakkad have recorded a UV index of 8, a level considered high enough to cause potential harm with extended exposure. Authorities have identified specific vulnerable locations such as Kottarakkara, Konni, Chengannur, Changanassery, Munnar, and Thrithala as being under heightened alert due to elevated radiation levels.

The Kerala State Disaster Management Authority has warned that direct sunlight exposure in these regions may lead to sunburn, skin damage, and eye-related health issues. Officials have also issued a yellow alert for Ernakulam, Thrissur, and Malappuram districts, where UV levels were recorded at 7. Meanwhile, Kozhikode and Wayanad reported slightly lower readings of 6, though authorities stressed that precautions remain necessary statewide.

Health experts and disaster management officials have advised residents to avoid outdoor activity between 10 a.m. and 3 p.m., when UV radiation is typically at its peak. They further cautioned that vulnerable groups, including outdoor workers, fishermen, transport operators, tourists, and individuals with pre-existing medical conditions, face a higher risk of complications from prolonged exposure.

Medical warnings highlight that excessive UV exposure can result in sunburn, skin disorders, eye damage, and other long-term health complications. Cancer patients, individuals with skin or eye diseases, and those with weakened immunity have been specifically advised to take extra precautions during this period of heightened radiation levels.

Authorities have recommended preventive measures such as wearing protective clothing, hats, and sunglasses, and using umbrellas when outdoors. Experts also advised taking regular breaks in shaded areas during travel or work, noting that reflective surfaces such as water bodies and sand can further intensify UV exposure, particularly in tropical and high-altitude regions like Kerala.
