    INTRODUCTION: The real-life short-term implications of electromagnetic fields (RF-EMF) on cognitive performance and health-related quality of life have not been well studied. The SPUTNIC study (Study Panel on Upcoming Technologies to study Non-Ionizing radiation and Cognition) aimed to investigate possible correlations between mobile phone radiation and human health, including cognition, health-related quality of life and sleep. METHODS: Adult participants tracked various daily markers of RF-EMF exposures (cordless calls, mobile calls, and mobile screen time 4 h prior to each assessment) as well as three health outcomes over ten study days: 1) cognitive performance, 2) health-related quality of life (HRQoL), and 3) sleep duration and quality. Cognitive performance was measured through six "game-like" tests, assessing verbal and visuo-spatial performance repeatedly. HRQoL was assessed as fatigue, mood and stress on a Likert-scale (1-10). Sleep duration and efficiency was measured using activity trackers. We fitted mixed models with random intercepts per participant on cognitive, HRQoL and sleep scores. Possible time-varying confounders were assessed at daily intervals by questionnaire and used for model adjustment. RESULTS: A total of 121 participants ultimately took part in the SPUTNIC study, including 63 from Besancon and 58 from Basel. Self-reported wireless phone use and screen time were sporadically associated with visuo-spatial and verbal cognitive performance, compatible with chance findings. We found a small but robust significant increase in stress 0.03 (0.00-0.06; on a 1-10 Likert-scale) in relation to a 10-min increase in mobile phone screen time. Sleep duration and quality were not associated with either cordless or mobile phone calls, or with screen time. DISCUSSION: The study did not find associations between short-term RF-EMF markers and cognitive performance, HRQoL, or sleep duration and quality. The most consistent finding was increased stress in relation to more screen time, but no association with cordless or mobile phone call time

In its subject coverage, Aerospace Medicine and Biology concentrates on the biological, physiological, psychological, and environmental effects to which man is subjected during and following simulated or actual flight in the earth's atmosphere or in interplanetary space. References describing similar effects of biological organisms of lower order are also included. Emphasis is placed on applied research, but reference to fundamental studies and theoretical principles related to experimental development also qualify for inclusion. Each entry in the bibliography consists of a bibliographic citation accompanied in most cases by an abstract

    Non visual effects of light: an overview and an Italian experience

    Get PDF
    Since the discovery of non-visual effect of light, consequences on human psychology and physiology have been investigated; however, effects on cognition of exposure to different spectral composition have been partially explored. Aim of this paper is an overview on researches developed in this field to compare general approaches and measurements protocols: the scarce knowledge of the physiological mechanisms, as well as the lack of shared methods, techniques, tools and procedures represent the weak point of this research. The impact of different procedures and experimental settings on results is shown, evidencing the need for scientifically consistent and internationally agreed procedures

    An idiographic approach to Idiopathic Environmental Intolerance attributed to Electromagnetic Fields (IEI-EMF) Part II. Ecological momentary assessment of three individuals with severe IEI-EMF

    Get PDF
    IEI-EMF refers to a self-reported sensitivity characterized by attribution of non-specific physical symptoms to exposure to weak EMFs. The majority of empirical results do not support the existence of a causal relationship between EMF and IEI-EMF. However, this conclusion was drawn from environmental and experimental studies that are not without methodological limitations. In the current study, as part of a complex biopsychosocial approach, an ecological momentary assessment (EMA) protocol was applied for the investigation of the temporal relationship between actual radio frequency (RF) EMF exposure and IEI-EMF, at the individual level. Continuous measurement of autonomic variables by holter electrocardiogram (ECG) monitors and the ambient RF EMF by personal dosimeters, as well as repeated (8/day) paper-and-pencil assessments of momentary internal states (symptoms, mood, perceived EMF intensity) and situational factors was conducted for 21 days with the participation of three individuals with severe IEI-EMF. Temporal relationships were examined by time series analyses. For two participants, the results did not support the association between the suspected EMF frequency range(s) and symptom reports. Nevertheless, the results revealed a reverse association with respect to another frequency range (GSM900 downlink), which contradicts the IEI-EMF condition. Autonomic activation related findings were inconsistent. For the third participant, the claimed association was partly supported, both for symptom reports and autonomic reactions (UMTS downlink, total RF; RMS values). The findings of this study suggest that IEI-EMF does not have a unitary aetiology. For certain individuals, a biophysical background cannot be excluded, whereas no such underlying factor appears to be at work for others. EMA is a useful method for the investigation of the aetiology of IEI-EMF

    DNA DAMAGE ASSESSMENT OF HUMAN LYMPHOCYTES AFTER WHOLE BODY EXPOSURE TO A SINUSOIDAL 60 Hz, 200 pT MAGNETIC FIELD

    Get PDF
    Introduction: Due to electricity production, transmission and commercial and residential uses, humans are exposed to extremely low frequency electromagnetic fields (ELF- EMF). Based on results from human epidemiological reports, animal in vivo and cell in vitro studies on the chronic exposure to ELF-EMF, adverse health effects of ELF-EMF remain controversial. Objective and Methods: The aim of this pilot project was to examine and compare DNA damage and clastogenic effects detected by the alkaline comet assay and the cytokinesis-block micronucleus assay, respectively, in peripheral human blood lymphocytes collected from healthy adult volunteers before and after (whole-body) exposure to a 200 pT, 60 Hz ELF-EMF. Results: There was no significant difference between pre- and post-exposure samples (p\u3e0.05). Moreover, magnetic field- exposed volunteers were not significantly different from sham-exposed subjects (p\u3e0.05). Conclusion: This study found no evidence that an acute, whole-body exposure to the magnetic field could cause DNA damage in human lymphocytes

    The aim of this study was to evaluate the effectiveness of Reiki (as well as the effectiveness of Physical Activities) on relatively healthy individuals (not hospital patients), members of a sample of 338 volunteers, and to confirm whether practicing Reiki contributes to psycho-emotional stabilization, having a beneficial impact on mood and emotional wellbeing. For the first time, a positive confirmation of Reiki was carried out in Ukraine. The respondents were divided into two main groups: non-Reikists (individuals who did not practice Reiki) and Reikists (individuals who practiced or taught Reiki). It was found that, in comparison with non-Reikists, the results obtained by Reikists were twice as good, showing higher levels of emotional comfort, less anxiety/dissatisfaction, and more optimism, energy and self-confidence. At that, senior pupils and university students of psychology performed worse. This study confirms that the practice of Reiki is a quickly healing, stimulating, long-term, and cost-effective technique, positively influencing to positive well-being, mood and psychosomatic responses
