Are WiFi Waves Harmful? What is their Impact on Humans?

The question of whether Wi-Fi waves are harmful to human health has been a subject of ongoing debate for many years, with no definitive answer yet.

What is Wi-Fi?

Wi-Fi is, in fact, a type of radio wave similar to the radio wave used in a microwave, but at a much lower intensity – about 100,000 times lower – and is claimed to be completely harmless to humans, at least in theory.

Does Wi-Fi affect the human body?

The answer is yes, but whether this impact is actually harmful is still a controversial issue.

As mentioned above, in theory, Wi-Fi waves have an intensity low enough not to cause any harm. However, in reality, the density of Wi-Fi devices in use is increasing, and these devices can emit other harmful radiation waves in addition to Wi-Fi.

Some studies have shown that people sleeping in an environment surrounded by too many Wi-Fi devices (router, camera, smartphone, computer, etc.) or keeping a Wi-Fi device near the bed for a long time may experience more sleep disturbances than others, while sleep disturbances can easily lead to other negative symptoms such as depression, stress, or high blood pressure.

Expert opinions

In the past 30 years, about 2000 to 3000 studies on radio waves have been conducted. The results are 50% stating that there is no evidence of harm, and 50% stating that there is.

Professor Malcolm Sperrin, an expert in the healthcare field, stated, “Research on radio waves is still being conducted in many countries. The evidence shows that Wi-Fi waves are within an allowable threshold and do not pose any harm to human health.”

Professor Will J. Stewart of the Royal Academy of Engineering in the UK stated, “Science has been researching the safety of mobile phones for many years, and most studies have found no significant evidence of harm.”

However, Professor Olle Johansson of the Karolinska Institute (Sweden) asserted that he has evidence showing that low-intensity radio waves have a negative impact on human chromosomes.

Conclusion

Although there is much controversy, currently, there is not enough research evidence to confirm that Wi-Fi waves can be harmful to the human body. Professor Sperrin also affirmed the difficulties in researching Wi-Fi waves, as it is currently impossible to prove the absence of any negative effects. “It is difficult to prove something that does not have any negative impact. Wi-Fi waves can only be eliminated when they are proven to be harmful.”
