2. How do electromagnetic fields interact with the body?

The human organism is an electrically conductive body. In conductive matter, electric and magnetic fields cause currents.

The body's surface efficiently shields low-frequency electric fields, whereas low-frequency magnetic fields penetrate into the body where they induce currents. If these currents exceed biological thresholds, they interact with physiological processes, especially nerve signals.

High-frequency fields penetrate into the body, too. Their energy is absorbed by the tissue (namely by its liquids) and converted into heat. Other interactions, so-called non-thermal effects, are not yet scientifically confirmed. The evidence for such effects increases. However, almost nothing is known about cause-effect mechanisms and health impacts.
