Idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF) is a controversial illness in which people report symptoms that they believe are triggered by exposure to EMF. Double-blind experiments have found no association between the presence of EMF and self-reported outcomes in people with IEI-EMF. No systematic review has assessed whether EMF exposure triggers physiological or cognitive changes in this group. Using a systematic literature search, we identified 29 single or double-blind experiments in which participants with IEI-EMF were exposed to different EMF levels and in which objectively measured outcomes were assessed. Five studies identified significant effects of exposure such as reduced heart rate and blood pressure, altered pupillary light reflex, reduced visual attention and perception, improved spatial memory, movement away from an EMF source during sleep and altered EEG during sleep. In most cases, these were isolated results that other studies failed to replicate. For the sleep EEG findings, the results reflected similar changes in the IEI-EMF participants and a non-IEI-EMF control group. At present, there is no reliable evidence to suggest that people with IEI-EMF experience unusual physiological reactions as a result of exposure to EMF. This supports suggestions that EMF is not the main cause of their ill health.
电磁超敏反应（IEI-EMF）是一种存在争议的病症，患者声称他们的症状是由接触电磁场（EMF）引发的。双盲实验发现，电磁场的存在与电磁超敏反应患者自我报告的结果之间并无关联。尚无系统性综述评估过电磁场暴露是否会引发该群体的生理或认知变化。通过系统性文献检索，我们找到了29项单盲或双盲实验，这些实验让电磁超敏反应患者接触不同强度的电磁场，并对客观测量的结果进行评估。五项研究发现了暴露的显著影响，如心率和血压降低、瞳孔光反射改变、视觉注意力和感知能力下降、空间记忆改善、睡眠期间远离电磁场源以及睡眠期间脑电图改变。在大多数情况下，这些都是孤立的结果，其他研究未能重复验证。对于睡眠脑电图的研究结果，电磁超敏反应患者和非电磁超敏反应对照组都出现了类似的变化。目前，没有可靠证据表明电磁超敏反应患者因接触电磁场而出现异常生理反应。这支持了电磁场并非他们健康问题主要原因的观点。
