This is as disingenuous as OP is speculative. There are plenty of studies in non-bullshit journals demonstrating that millimeter-wavelength electromagnetic fields can affect voltage-gated calcium channels in the body. It seems highly unlikely that increased long-term exposure above natural baseline would cause autoimmune disease, but it also seems unlikely that it would have no other effect on the body.
