What is the UV Index? 🤔

The UV Index is a scale that measures the intensity of ultraviolet (UV) radiation from the sun at a particular place and time. It ranges from 0 to 11+, with higher numbers indicating a greater risk of harm from unprotected sun exposure. In Mexico City, due to its altitude and latitude, the UV index can often reach high levels, especially during the dry season (November to May).

Understanding the UV Index Scale:

• 0-2 (Low): Minimal risk. Wear sunglasses on bright days.
• 3-5 (Moderate): Seek shade during midday hours. Apply sunscreen and wear protective clothing.
• 6-7 (High): Protection is essential. Reduce time in the sun between 10 a.m. and 4 p.m. Apply sunscreen, wear protective clothing, and wear a hat and sunglasses.
• 8-10 (Very High): Extra precautions are needed. Unprotected skin and eyes can be damaged in minutes. Avoid the sun between 10 a.m. and 4 p.m.
• 11+ (Extreme): Take all precautions. Unprotected skin and eyes can burn in minutes. Try to avoid sun exposure during peak hours.

Why is Mexico City's UV Index So High? ☀️

Several factors contribute to the high UV index in Mexico City:

• Altitude: Mexico City is located at an altitude of over 7,000 feet (2,200 meters) above sea level. At higher altitudes, the atmosphere is thinner, meaning there is less atmosphere to absorb UV radiation.
• Latitude: Mexico City is located relatively close to the equator. The closer you are to the equator, the more direct sunlight you receive.
• Air Quality: While Mexico City has made strides in improving air quality, pollution can still sometimes trap UV rays, increasing their intensity.

How to Protect Yourself from UV Radiation in Mexico City 🧴

Sunscreen is Your Best Friend:

Apply a broad-spectrum sunscreen with an SPF of 30 or higher to all exposed skin, even on cloudy days. Reapply every two hours, or more often if you're swimming or sweating.

Sunglasses: Protect Your Eyes:

Wear sunglasses that block 99-100% of UVA and UVB rays to protect your eyes from damage.

Hats and Protective Clothing:

Wear a wide-brimmed hat to shade your face, ears, and neck. Wear long sleeves and pants when possible.

Seek Shade During Peak Hours:

The sun's rays are strongest between 10 a.m. and 4 p.m. Try to limit your time in direct sunlight during these hours. Explore indoor attractions or find a shady spot to relax. Parks like Chapultepec Park offer plenty of shaded areas.

Stay Hydrated:

Drink plenty of water to keep your skin hydrated. Dehydration can make your skin more susceptible to sun damage.
