Is there evidence that electromagnetic energy emitted by power lines or cell phones can cause changes in stress protein levels in human cells?
Stress proteins are a family of naturally occurring proteins that are found in all cells. Some of these stress proteins are expressed in response to heat, cold or other environmental stressors. Some researchers have speculated that EMFs may exert biological effects on cells by altering the levels of these stress proteins. Health Canada’s own research studies have found no evidence that EMFs can alter stress protein levels in human cells, even at levels far above Health Canada’s RF exposure limits. In addition, Health Canada recently reviewed all the available scientific evidence on this potential EMF effect and concluded that there is no credible scientific evidence that low-level EMFs emitted by power lines or cell phones can cause changes in stress protein levels in human or animal cells.
