With Mexico City's UV index reaching up to 12.1 today, it's crucial to take all necessary precautions to avoid unprotected skin and eye damage, as they can burn in a matter of minutes.
It's best to avoid sun exposure altogether between 10 a.m. and 4 p.m. If you must be outdoors, seek shade and wear sun protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.
Don't forget to generously apply broad-spectrum SPF 30+ sunscreen every two hours, even on cloudy days and after swimming or sweating.
Remember that bright surfaces like sand, water, and snow can increase UV exposure, so take extra care.
