The first thing that Héroux explained is that low-frequency fields, high-frequency fields, electric fields, microwaves and magnetic fields all have similar biological effects on the human body. "It's true that frequency influences the effects," Héroux noted, "but basically … I could, using an electric field or a magnetic field, produce the same effect in a cell. Most higher frequency signals have enough low-frequency components to have a lot in common with low-frequency components."
