What are UV rays?

UV rays are invisible light that comes from the sun and can affect your skin.

Imagine you're playing outside on a bright day, the sun is shining strongly, and after a while, your skin feels warm or even a little sore. That’s because the sun sends out tiny energy packets called UV rays, which are like invisible little messengers traveling through the air to reach you.

Think of UV rays as super tiny invisible sunglasses, but instead of protecting your eyes, they try to touch your skin. There are different kinds of these rays: some are like gentle nudges (called UVA), and others are like strong taps (called UVB).

When the sun is high in the sky or on a sunny day with no clouds, those UV rays become stronger, just like how a loud voice can be more annoying than a quiet one.

Your skin has to work hard to protect you from these tiny messengers. If it gets too much of them, especially when you're outside for long periods, it might get tired or even burn, just like how your hands can get sore after holding a hot chocolate for too long.

So next time you’re playing outside, remember that the sun is sending out invisible little messages called UV rays!
