Bengaluru on UV alert: Index hits extreme level 13 despite 32°C temperature

City records dangerous UV index spike from 10 to 13 in just two days; experts warn of skin damage and cancer risk as per World Health Organization standards.

Bengaluru residents are facing a double impact this summer, rising heat and a sharp spike in ultraviolet (UV) radiation. This is not just an ordinary summer. While the temperature stands at around 32 degrees Celsius, what has shocked many is the sudden rise in the UV index.

On Tuesday, the city recorded a UV index of 13, which falls under the “Extreme” category. Normally, a UV index of 8 is considered the upper safe limit. Any reading above 8 is classified as dangerous. According to the World Health Organization, such levels can pose serious health risks.

What is more concerning is that within just two days, the UV index jumped from 10 to 13. At the very beginning of summer, such a record-level increase has raised alarms among health observers.

What Are UV Rays?

Ultraviolet rays are invisible electromagnetic rays that come from the sun. They cannot be seen by the human eye, but they have the ability to penetrate deep layers of the skin.

Understanding the UV Index Scale

The UV index is measured on the following scale:

0-2: Low
3-5: Moderate
6-7: High
8-10: Very High
11 and above: Extreme

With Bengaluru touching 13, the city is currently in the highest and most dangerous category.

Health Effects of High UV Exposure

Exposure to strong UV radiation can cause multiple health problems. These include wrinkles, premature ageing of the skin, tanning and sunburn (redness of the skin). It can also lead to DNA damage and significantly increase the risk of skin cancer.

How to Protect Yourself

Experts advise residents to take precautions seriously. Using sunscreen with SPF 30 or above is recommended. Wearing UV-protection sunglasses, caps or carrying umbrellas can reduce direct exposure. People are advised to avoid direct sunlight between 11 am and 3 pm. Drinking plenty of water is also important to stay hydrated.

With UV levels already at extreme levels early in the season, citizens are urged to stay alert and take necessary protective measures.
