Ben Greenfield on health: what the evidence says · JRE #1069
“But it goes into this idea of what are called voltage-gated calcium channels on your cell membrane, and those actually get affected by Wi-Fi. And apparently you see like a change in the electrochemical balance across the actual membrane in response to things like Wi-Fi.”
What the evidence says
Greenfield's claim traces to a fringe hypothesis, most associated with biochemist Martin Pall, that low-intensity radiofrequency and Wi-Fi-range electromagnetic fields activate voltage-gated calcium channels (VGCCs) in cell membranes and thereby cause a range of harms. This hypothesis has been published mainly by Pall and a small number of collaborators in lower-tier journals and has not been replicated or accepted by mainstream biophysics, radiation biology, or public health agencies. Wi-Fi and cell phone signals fall in the non-ionizing part of the electromagnetic spectrum, which the U.S. National Cancer Institute states carries too little energy to damage DNA, with heating the only consistently established biological effect at typical exposure levels. The WHO's review of roughly 25,000 published studies over 30 years found current evidence does not confirm health consequences from low-level electromagnetic field exposure, and it notes some diffuse symptoms sometimes attributed to EMF exposure are not supported by the evidence as causally linked. No major health or scientific body currently endorses the VGCC-activation mechanism as an established route by which Wi-Fi harms cells. The claim's specific mechanism is therefore considered unsupported by mainstream science, distinct from the fringe literature it draws on.
