Why Are These Cities Known As Cities With Highest Uv Index In The World?

There are many reasons why these cities are known as having the highest UV index in the world. For one, they are located near the equator where the sun’s rays are most direct. 

Additionally, they have high altitudes which also increases the amount of UV radiation that reaches the ground. 

And finally, they tend to have clear skies with little pollution or cloud cover which allows more of the sun’s harmful UV rays to reach the earth’s surface.

These factors all contribute to why these cities typically have some of the highest UV index readings in the world. 

And while there is no denying that exposure to high levels of UV radiation can be dangerous, it is important to remember that everyone’s skin is different and will react differently to sunlight. 

So even if you don’t live in one of these cities with a high UV index, it is still important to be cautious when spending time outdoors and make sure to use sunscreen and wear protective clothing when necessary.
