EM field have characteristics. Frequency spectrum, power and so on.
If lowering of EMF around the Earth (natural one?) is harmful, then, there are no problems to reproduce it artificially to fix the problem. Humans are the kings of creating EMFs today and creating them a lot.
Also, it is possible that humans could be harmed by low levels of ionizing radiation that comes from space and from radioactive elements in Earth crust surrounding us.
