Sat Mar 15 08:20:00 UTC 2025: ## Kerala Faces High UV Radiation, Leading to Increased Cataract Cases
**Thiruvananthapuram:** Kerala is facing alarmingly high levels of ultraviolet (UV) radiation, leading to concerns about a surge in cataract cases and other health issues. The state’s Disaster Management Department has recorded dangerously high UV index levels across several districts, prompting warnings to the public.
Experts link the high UV radiation to Kerala’s status as the state with the highest number of cataract patients in India. Prolonged exposure to UV rays, ranging from 10 to 400 nanometers in wavelength, can cause sunburn, skin diseases, eye problems, and other health complications.
The UV index, measuring atmospheric UV radiation levels (0-11+), is currently at dangerous levels in several parts of Kerala. Levels between 0 and 5 are considered safe, 6-7 triggers a yellow alert, 8-10 an orange alert, and above 11 a red alert. The most harmful UV radiation, UVB (280-314 nm), is responsible for sunburn and tanning. While UVA (315-399 nm) and UVC (100-279 nm, mostly absorbed by the ozone layer) also contribute, excessive exposure to any UV radiation poses health risks. Although some UV radiation is beneficial for Vitamin D production, overexposure is detrimental.
The highest UV index levels are recorded between 10 am and 3 pm. Authorities urge people, especially those working outdoors (fishermen, construction workers), and those with weakened immune systems, to take precautions during these hours by limiting sun exposure, wearing protective clothing, and using sunscreen. The public is also advised to wear sunglasses to protect their eyes. The ongoing high UV levels underscore the importance of sun safety measures to mitigate the increasing risks of cataracts, skin cancer, and other health issues in Kerala.
