When 81.4% of 269 peer-reviewed studies document cellular effects from electromagnetic field exposure, we're looking at one of the most robust areas of EMF research. The science demonstrates that our cells respond to EMF exposure in measurable, biological ways that extend far beyond simple heating effects. These documented cellular effects span a remarkable range of biological processes.
When we examine the research on cellular effects, we find that 66% of studies published after 2007 show measurable changes in how your cells make and fold proteins when exposed to EMF levels typical of everyday wireless devices.
Research shows that 66% of studies published after 2007 report measurable effects on protein and gene expression at intensity levels commonly used by wireless devices, indicating a clear biological response to EMF exposure at current regulatory limits.
