These chemical compounds primarily work by activating estrogen receptors in your cells, much like how EMFs activate voltage-gated calcium channels. This activation will increase calcium inflow into cells, and extra intracellular calcium dramatically will increase superoxide and nitric oxide. These shortly mix to type peroxynitrite, which is a particularly potent oxidant stressor. This results in extreme oxidative stress and mobile injury.
3. Electromagnetic fields (EMFs) — The third vital risk to mobile well being comes from the rising publicity to EMFs because of the proliferation of wi-fi applied sciences. EMFs improve calcium ion concentrations inside cells, ensuing within the manufacturing of dangerous free radicals.
