Munnar records Kerala's highest UV rays index: What should tourists be careful of?

As daytime temperatures climb in Kerala, an invisible threat is rising alongside them. Increasing levels of ultraviolet radiation, as reflected in the UV index, are now a serious concern in Idukki. Recently, the hill station recorded the highest UV index in the state, with Munnar reaching 7. A UV index between 6 and 7 warrants a yellow alert, while levels from 8 to 10 call for an orange alert requiring heightened caution. A reading above 11 triggers a red alert. The highest UV levels are usually recorded between 10 am and 3 pm. Those in areas where the index exceeds 6 should take strict precautions while stepping outdoors.

What tourists should know
With temperatures rising, the Kerala State Disaster Management Authority has also issued precautionary guidelines. Intense heat can lead to serious health problems, including sunstroke and dehydration. Health experts advise drinking clean water regularly to prevent dehydration and caution that even minor symptoms should not be ignored.

Strong UV exposure can initially cause skin irritation and may subsequently lead to sunburn. Prolonged exposure to heat can also result in dehydration. Even at an ambient temperature of 35 degrees Celsius, elevated UV levels can make the body feel as if it is exposed to heat of up to 45 degrees. This accelerates water loss from the body, increasing the risk of burns, sunstroke, and severe physical exhaustion. Experts also warn that prolonged exposure to high levels of UV radiation may increase the risk of eye disorders such as cataracts and skin diseases. 

How to stay safe?
Avoid prolonged direct exposure to sunlight between 11 am and 3 pm.
Plan your tours to avoid peak hours.
Use an umbrella when stepping out.
Carry boiled and cooled drinking water at all times.
If you feel fatigued, move to a shaded area and drink plenty of water.
If exhaustion worsens, seek assistance from those nearby.
