Säger du med samma enfald och utan källhänvisningar som föregående debattör?
Nej det gör jag inte. Men om jag känner dig rätt så betyder den samlade vetenskapen ingenting då den utan tvekan manipulerats av judiska bankirer och rymdödlor med starka kopplingar till illuminati och rotschildfamiljen.

Although individuals who report electromagnetic hypersensitivity believe that electromagnetic fields from common electrical devices trigger or exacerbate their symptoms, it has not been established that these fields play any role in the etiology of sensitivity symptoms. Exposures are to intensity levels below those generally accepted to cause physiological effects, and the diverse physiological effects reported are not what would be expected from high intensity electromagnetic fields. Sufferers and their support groups are convinced of a causal relationship with electromagnetic fields, but presently the scientific literature does not support such a link. Some professionals consider electromagnetic hypersensitivity to be a physical condition with an unclear cause, while others suggest that some aspects may be psychological.[16][1] Psychological reveiwers have suggested that psychologic mechanisms may play at least some role in causing or exacerbating EHS symptoms.[17] Whereas other researchers find neurophysiological effects, altered central nervous system function and a more general imbalance in autonomic nervous system regulation.[18][19][20][21][16]
Some sufferers and support groups argue that studies may be influenced by the possible political implications of negative health effects from electromagnetic fields.[22]
In 2005, a systematic review looked at the results of 31 experiments testing the role of electromagnetic fields in causing ES. Each of these experiments exposed people who reported electromagnetic hypersensitivity to genuine and sham electromagnetic fields under single- or double-blind conditions.[1] The review concluded that:
"The symptoms described by 'electromagnetic hypersensitivity' sufferers can be severe and are sometimes disabling. However, it has proved difficult to show under blind conditions that exposure to electromagnetic fields can trigger these symptoms. This suggests that 'electromagnetic hypersensitivity' is unrelated to the presence of electromagnetic fields, although more research into this phenomenon is required."
Seven studies were found which did report an association, while 24 could not find any association with electromagnetic fields. However, of the seven positive studies, two could not be replicated even by the original authors, three had serious methodological shortcomings, and the final two presented contradictory results. Since then, several more double-blind experiments have been published, each of which has suggested that people who report electromagnetic hypersensitivity are unable to detect the presence of electromagnetic fields and are as likely to report ill health following a sham exposure, as they are following exposure to genuine electromagnetic fields.[23][24][25]
One of the studies which Rubin et al reviewed, known as the Essex study, received some criticism for its methodology and analysis, and the authors responded in full to these initial criticisms.[26] The authors noted that their study says nothing about the long-term effects of exposure to electromagnetic fields, but those affected generally claimed to respond to the fields within a few minutes.
In 2008, another systematic review reached the same conclusion as Rubin et al.[2]
A 2005 report by the UK Health Protection Agency concluded that electromagnetic hypersensitivity needs to be considered in ways other than its etiology; that is, the suffering is real, even if the underlying cause is not thought to be related to electromagnetic fields. They also wrote that considering only whether electromagnetic radiation was a causative factor was not meeting the needs of sufferers, although continued research on etiology was essential.[4]
In 2002, some controversy over the causal relationship was demonstrated by the Freiburger Appeal, a petition originated by the German environmental medical lobby group IGUMED, which stated that "we can see a clear temporal and spatial exposure between the appearance of [certain] disease and exposure to pulsed high-frequency microwave radiation", and demanding radical restrictions on mobile phone use.[27] To address some of these concerns, and others, Hocking advised in a 2006 WHO proceedings that the test type and duration should be tailored to the individual, and that washout times are needed to prevent a carry-over effect of previous exposure.[28] However, in 2005 the World Health Organization concluded that there is no known scientific basis for the belief that electromagnetic hypersensitivity is caused by exposure to electromagnetic fields.[16]
