Some individuals are reporting being sensitive to electromagnetic fields. They report some unspecific symptoms like headeache, sleep disruption, heart palpitations, itching, etc. The lack of scientific objective links between EHS symptoms and EMF exposure renders the diagnosis of EHS more complex. Our present work aimed to look for the effect of RF EMF exposure on saliva alpha amylase (AA) and other biological markers such as cortisol and IgA in EHS individuals. Ten EHS individuals participated in this double-blind provocation study. They were aged between 35 and 63 yr. Experiment consisted of two sessions (sham and real exposure). No external EMF sources were allowed, and the exposure consisted of a series of EMF signals emitted from a generator (Rhode & Schwarz) and a horn antenna (Schwarzbeck BBHA9120b). Consecutive RF signals were applied: GSM 900, GSM 1800, DECT, and Wi-Fi signals for 5 min each. : Exposure to 4 consecutive radiofrequency signals did not show any significant modification ( > .05) on the saliva AA, cortisol or immunoglobulin A concentrations in the electrohypersensitive individuals. Our study, under current conditions, do not presently allow us to propose an identification of marker for EHS.
一些人报告对电磁场敏感。他们报告了一些非特异性症状，如头痛、睡眠障碍、心悸、瘙痒等。EHS 症状与电磁场暴露之间缺乏科学客观的联系，使得 EHS 的诊断更加复杂。我们目前的工作旨在研究射频电磁场暴露对 EHS 个体唾液 α-淀粉酶（AA）和其他生物标志物（如皮质醇和 IgA）的影响。10 名 EHS 个体参加了这项双盲激发研究。他们的年龄在 35 岁至 63 岁之间。实验包括两个阶段（假暴露和真暴露）。不允许使用外部电磁场源，暴露由发生器（罗德与施瓦茨）和喇叭天线（施瓦茨贝克 BBHA9120b）发出的一系列电磁场信号组成。连续应用射频信号：GSM900、GSM1800、DECT 和 Wi-Fi 信号，每个信号持续 5 分钟。在电过敏个体中，连续暴露于 4 种射频信号并未显示唾液 AA、皮质醇或免疫球蛋白 A 浓度有任何显著变化（>0.05）。在目前的条件下，我们的研究目前还不能提出用于识别 EHS 的标志物。
