I read somewhere that a man dies if he is isolated from natural electromagnetic fields and waves. (I imply fields of radio frequencies and below.)

Is it true?

note that visible light and infra-red are also EM waves. Humans can survive in total darkness for a while though....it would be pretty cold too! –  Memming Dec 16 '13 at 14:46
    
@Memming: certainly light, UV, and infrared don't count in my question –  porton Dec 16 '13 at 14:47
    
what frequency of EM wave, then, are you talking about? Without the magnetic field of earth, there would be too much solar wind/cosmic ray as well. –  Memming Dec 16 '13 at 14:48
    
@Memming: I am about radio frequencies and below. I do not ask on indirect effects of EM on survival of human (such as about Earth field protecting from Sun rays), only about direct effect of EM on human body. –  porton Dec 16 '13 at 14:51

I never heard of anybody dying in a Faraday cage, so I don't think lack of EM or natural electric field has any effect, at least short term. –  Memming Dec 16 '13 at 14:59

I've never heard of such a thing, and a quick Scholar search didn't yield anything significant. In fact, artificial radio waves are used in things that usually save lives, like MRIs.

If we were truly agnostic about this, we could say that it might or might not have an effect on human survival due to the general lack of evidence or even indication of a claim, but like the orbiting teacup, it's safe to assume that given our current extensive set of knowledge of biology, radiowaves do not affect human at all, and that as it has not been observed, the claim doesn't have a scientific basis.
