Our world is so wired these days that is seems electronics are everywhere. Everyone on the bus or train is glued to their cell phones, there's Wi-Fi in grade school classrooms and some cities even offer it everywhere you go.
If you're worried about the health risks of these devices, it can seem like the world is full of hidden dangers. Maybe you've read articles like this one, or you've seen memes like the one below, and you're worried that exposing yourself or your children to Wi-Fi can give them cancer.
Thankfully, the science is very clear: these devices don't cause cancer.
We should explain: cell phones and Wi-Fi routers both use microwaves, which some people claim will give you cancer.
In reality, these microwaves are the same kind of radio signals used by your TV antenna, and they're too weak to affect your body. In fact, the waves sent out by your cell phone are actually weaker than the ones that light is made of.
While it's true that sunlight can cause cancer, UV light (which is what damages your cells and causes the cancer) is much, much stronger than anything your cell phone puts out.
When you see claims like the one involving the water cress it's important to be skeptical. A science project by 9th graders isn't real evidence of anything, and in that case there was actually another plant from the same experiment that was perfectly fine.
Scientists have made scary announcements, like when the International Agency for Cancer Research labeled cell phones as a "possible human carcinogen," but if you dig deeper this really means they don't have evidence that cell phones cause cancer.
Another common claim is that people can develop sensitivities or allergies to these electrical signals, but well-informed groups like the World Health Organization say there's no evidence of that either.
One last piece of evidence: over the last few decades as these technologies have become so common in our everyday life, the National Cancer Institute hasn't recorded any kind of uptick in cancer diagnoses.
It's natural to question things that could impact your health, but it's also important to do your research and get all the facts. In this case the evidence is clear: there's no reason to worry about cell phones or Wi-Fi giving you cancer.
