Beware of UV exposure

These days my smartphone alerts me on high UV index. I checked and found that this index helps you be aware and UV effects and protect yourself with sunscreen and avoiding sun exposure time ...etc

if your smartphone doesnt show, you can directly check it on accuweather.com for your city, and i see Indian cities easily above 5, chennai at 8!

"The UV Index scale used in the United States conforms with international guidelines for UVI reporting established by the World Health Organization"

A UV Index reading of 0 to 2 means low danger from the sun's UV rays for the average person.
3 to 5 means moderate risk of harm from unprotected sun exposure.
6 to 7 means high risk of harm from unprotected sun exposure. Protection against skin and eye damage is needed.
8 to 10 means very high risk of harm from unprotected sun exposure. Take extra precautions because unprotected skin and eyes will be damaged and can burn quickly.
11 or more means extreme risk of harm from unprotected sun exposure. Take all precautions because unprotected skin and eyes can burn in minutes.

Precautions when high UV:
Minimize sun exposure between 10 a.m. and 4 p.m.
If outdoors, seek shade and wear protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.
Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating.
Watch out for bright surfaces, like sand, water and snow, which reflect UV and increase exposure.
