There is no evidence or research which directly shows that 5G technology causes harm to humans. Humans have been in close contact with high frequency radio waves for enough time to study the effects of these waves on their body. A Forbes report displayed that of the 4,500 people in the United Kingdom who worked in close proximity to radiofrequency radiation, there was no evidence that they had higher rates of cancer or illness than any other citizen. These workers are allowed to be in contact with five times as much radiofrequency radiation than the public. If there were any adverse effects of 5G waves, these workers would have been the first to display them. Beyond this, the World Health Organization also conducted a project to decipher whether or not 5G would be a threat. They found that it was not at all harmful and that, “[t]o date, no adverse health effects from low level, long term exposure to radiofrequency or power frequency fields have been confirmed, but scientists are actively continuing to research this area." There has yet to be conclusive evidence of any sort of harm that 5G could cause to humans. The fear that surrounds this new technology is unfounded hysteria with no scientific backing.
Some argue that the reason that many studies disprove the health concerns of 5G is that they have strong ties to the technology industry that would benefit from 5G. For example, a 2017 article in the International Journal of Oncology, argued that several members of the World Health Organization's core leaders on their risk assessment project were in a very "industry loyal" NGO, the ICNIRP.
