Are WiFi waves harmful?

WiFi waves are like invisible radio messages that help your phone and tablet talk to the internet.

Imagine you have a toy walkie-talkie. When you press the button and speak, your friend’s walkie-talkie gets the message across the room, even if they’re not right next to you. That’s kind of how WiFi waves work, but instead of walking across the room, the messages travel through the air in tiny invisible ripples called radio waves.

These radio waves are very weak and don’t do anything harmful to your body, like how a soft whisper doesn’t hurt your ears. In fact, you’re already surrounded by similar kinds of waves every day: your microwave uses them to heat up your popcorn, and your radio uses them to play music!

So even though WiFi is always on in your house, it’s not doing anything dangerous, just sending messages so your devices can stay connected.

Scientists have studied radio waves for a long time. They’ve tested how strong the WiFi waves are and compared them to other things you use every day, like your phone or even your microwave. What they found is that WiFi waves are much weaker than those, kind of like comparing a whisper to a shout!
