OBJECTIVES: The aim of the study was to assess the influence of electromagnetic fields (EMFs) generated by wireless connectivity systems on the occurrence of emotional disorders in women working in the health service and in trade. We also analyzed the relationship between physical activity and emotional state. METHODS AND RESULTS: The study was conducted on a sample of 200 women aged 25 to 35, in Lublin, Poland, in 2017. Shopping center staff spent more time using their mobile phones for conversations and online activities. Medical staff were exposed to stronger electromagnetic fields generated by stationary wireless phones than shopping center staff, they were less exposed to the effect of relay stations. CONCLUSIONS: The study showed that exposure to electromagnetic fields from GSM 900 and 1800 generated by base stations contributed to the occurrence of depressive disorders among medical personnel, while exposure to WLAN EMF had the opposite effect. Spending time on phone conversations decreased the feeling of depression and increased trait anxiety in medical staff. Spending free time on physical activity intensified depressive states in women working in trade. Further studies on the influence of low-frequency EMFs on the human nervous system are needed.
