By now you are probably aware of the importance of applying sun protection not only when exposing to the sun but any time you are out of home.

Many people haven’t acquired this habit yet, probably because they are unaware of the importance of protecting the skin from the sun rays. There are still many things left to learn about how the sun affects our skin, but a good starting point is knowing how to distinguish what UVA and UVB rays are.

Ultraviolet rays, commonly known as UV rays, are a type of electromagnetic radiation that comes from the Sun and hits the Earth. The difference with the visible light rays is that the latter are longer and visible to the human eye.

Therefore, UVA and UVB rays are different types of UV light. Both fall into the short wavelength category, and that’s why we can’t see them. However, just because you can’t see them doesn’t mean they won’t affect you.

In the next post we will see how to distinguish them, which ones are more dangerous and how to protect ourselves from them.
