Wi-Fi radiation does not pose a threat to the human blood-brain barrier, according to experts. Robert F. Kennedy Jr., a 2024 Democratic presidential candidate, claimed that Wi-Fi radiation opens up the blood-brain barrier, allowing toxins to enter the brain. However, existing research does not support this claim, and very few long-term, peer-reviewed studies have been conducted on Wi-Fi radiation's effects on humans. While high levels of radiation from activities like radiation therapy can increase the blood-brain barrier's permeability, Wi-Fi radiation levels are not strong enough to have the same effect. Wi-Fi radiation is considered nonionizing radiation, meaning it does not have enough energy to break down molecules in living matter. Health agencies agree that there is no convincing evidence that Wi-Fi radiation is a health hazard at exposure levels below accepted limits. However, there is still a degree of uncertainty, and more research is needed. Additionally, it is challenging to study the long-term effects of Wi-Fi radiation on humans due to the difficulty of isolating exposure solely to Wi-Fi radiation. The Federal Communications Commission's wireless radiation safety standards have not changed since 1996, but a federal appeals court ordered the FCC to revisit the standards in 2021 to consider potential harm from cellphone radiation. In conclusion, the claim that Wi-Fi radiation opens up the blood-brain barrier is not supported by scientific evidence.
