Wifi waves cause cancer?

There have been many warnings about the negative effects of wifi waves on human health in general and children in particular. However, all research has only stopped at the "possible" level.

Recently, Mayor Livio Tola in the town of Borgofranco d'lvra in Piedmont, Italy, made a controversial decision: Requesting to turn off wifi in two schools in the town because of concerns that electromagnetic waves emitted from this device are harmful to children.

"It's not that we're against technology, it's just a precautionary measure," he said. "We can't be sure whether the electromagnetic waves are harmful or not. But maybe 20 years from now, someone will thank us."

There are many warnings about the dangers of wifi, and many are misleading or exaggerated. The World Health Organization is still studying the effects of wireless routers.

It should be noted that while WHO classifies wifi waves as radio frequency electromagnetic fields (RF/EMF) - a group 2B carcinogen - meaning that at certain exposure levels, under certain conditions, it can be harmful enough to cause disease, it should be noted that coffee is also classified in this group.

While Sir William Stewart - Chairman of the UK Health Protection Agency - affirmed that there is now evidence showing that radiation waves emitted from devices such as mobile phones or wifi transmitters, even at low levels, have negative impacts on human health, other experts disagree with this view.

Lawrie Challis, professor at the University of Nottingham and chair of the programme management committee of the Mobile Telecommunications and Health Research Organisation, said: "Wifi waves have virtually no adverse effects on health. Wifi transmitters are usually not strong and are located far away from users."

Some researchers have also pointed out that while wireless routers do emit radiation, this type of radiation is extremely low energy and non-ionizing, meaning it does not have the power to affect human cells.

Sunlight is even more dangerous and ionizing, with the ability to change DNA structure and cause cancer.

According to Professor Malcolm Sperrin, a medical expert: "Wifi waves are low-intensity radio waves with wavelengths similar to those used in microwave ovens. But the intensity of wifi waves is 100,000 times lower than that of microwaves."

Over the past 30 years, there have been about 2,000-3,000 studies on radio waves. The results are 50% that there is no evidence of harm and 50% that there is.

And, while waiting for studies to clearly confirm whether wifi waves are beneficial or harmful, we should not spend all day hugging computers, mobile phones or wireless electronic devices; to not only live in a virtual environment; to increase physical activity to improve health, interact with people and real society.
