Edited sentence: " Comments have been made that the sham was also emitting RF radiation and therefore was not truly a sham, but this concern has been addressed by the study authors.A common position presented regarding these effects is that, since they are not well understood, a precautionary principle approach would suggest minimizing exposure whenever possible.Because the extent of Non-thermal effects is not fully established, they may be beneficial or harmful.However, it should be recognized that the claims of biological hazards from low-energy electromagnetic radios (e.It does not seem to be a congenital condition and theories have been put forth that some form of external trigger such as previous chemical exposure may bring about this electrical sensitivity (ES).It is not yet understood whether the participants withdrew from a reaction to the background exposure levels (which were not measured) or from a stress or nocebo response.Some studies have even suggested that a small percentage of the population may be electromagnetically sensitive and claim to physically react to very low level fields even in double-blind experiments, such as participants withdrawing from symptoms when not being exposed in the 2006 Rubin study.The theoretical mechanism of action of non-thermal electromagnetic fields is not fully understood, but there are some established biological effects for ELF.There is also a body of evidence which supports the existence of complex biological effects of weaker non-thermal electromagnetic fields (see Bioelectromagnetics), including weak ELF magnetic fields and modulated RF and microwave fields
