Thiruvananthapuram: A sharp rise in ultraviolet radiation levels across Kerala has prompted the Kerala State Disaster Management Authority to issue alerts in multiple districts, urging residents to limit exposure to direct sunlight. Authorities have warned that the current conditions could pose health risks, particularly during peak daytime hours.

Orange alert in six districts

Data released on Thursday showed that Pathanamthitta, Alappuzha, Kottayam, Idukki, Kollam and Palakkad have recorded a UV index of 8, a level considered high and potentially harmful.

Within these districts, specific locations placed under orange alert include Kottarakkara, Konni, Chengannur, Changanassery, Munnar and Thrithala.

Officials cautioned that direct exposure to sunlight in these areas may result in sunburn, skin-related conditions and eye problems.

Yellow alert in other regions

Meanwhile, Ernakulam (Kalamassery), Thrissur (Ollur) and Malappuram (Ponnani) recorded a UV index of 7, prompting a yellow alert.

Kozhikode and Wayanad reported slightly lower levels of 6. Despite this, authorities pointed out that precautions are necessary across the state.

Peak exposure hours identified

The Kerala State Disaster Management Authority noted that ultraviolet radiation is usually strongest between 10 am and 3 pm. People have been advised to reduce outdoor activity during this period to minimise health risks.

Health risks highlighted

Extended exposure to ultraviolet rays can lead to several health concerns, including sunburn, skin diseases, eye damage and other complications. Vulnerable groups are especially at risk under such conditions.

Those identified as more susceptible include outdoor workers, fishermen, transport operators, tourists, motorbike riders and individuals with existing health conditions such as skin disorders, eye diseases, albinism and weakened immunity.

Cancer patients have also been advised to take extra precautions.

Safety measures recommended

Authorities have recommended the use of protective measures when stepping outdoors. These include wearing hats, using umbrellas and putting on sunglasses.

People are also advised to wear full coverage cotton clothing and take regular breaks in shaded areas while travelling or working outside to reduce exposure.

Factors increasing UV intensity

Experts pointed out that ultraviolet radiation levels are typically higher in tropical and high-altitude regions. Even on clear days, radiation can remain strong.

They also noted that reflective surfaces such as water bodies and sand can intensify exposure, increasing the risk of harm.
