Polarized EMFs/EMR can have increased biological activity, due to\n    1) Ability to produce constructive interference effects and amplify their intensities at many locations.\n    2) Ability to force all charged/polar molecules and especially free ions within and around all living cells to oscillate on parallel planes and in phase with the applied polarized field. Such ionic forced-oscillations exert additive electrostatic forces on the sensors of cell membrane electro-sensitive ion channels, resulting in their irregular gating and consequent disruption of the cell’s electrochemical balance.\n    These features render man-made EMFs/EMR more bioactive than natural non-ionizing EMFs/EMR. This explains the increasing number of biological effects discovered during the past few decades to be induced by man-made EMFs, in contrast to natural EMFs. \nScientific Literature:\n-The fetal stage of life is the most vulnerable to any toxic exposure. Kaiser researcher Dr. De-Kun Li  (2017) performed a robust prospective cohort study of over 900 pregnant women revealing the strong association between exposure to non-ionizing electromagnetic radiation from a variety of sources and miscarriage with nearly a 3 fold increase risk. This study supports and strengthens prior research. He states, “This study provides fresh evidence, directly from a human population, that MF non-ionizing radiation could have adverse biological impacts on human health.”\n-Relationship between the Exposure to Magnetic Fields during Pregnancy and Risk of Abortion: A Review Article.
