Provocation study using heart rate variability shows microwave radiation from 2.4 GHz cordless phone affects autonomic nervous system

  title={Provocation study using heart rate variability shows microwave radiation from 2.4 GHz cordless phone affects autonomic nervous system},
  author={Magda Havas and Jeffrey Marrongelle and Bernard Pollner and Elizabeth Kelley and Camilla R. G. Rees and Lisa Tully},
Aim: The effect of pulsed (100 Hz) microwave (MW) radiation on heart rate variability (HRV) was tested in a double blind study. Materials and Methods: Twenty-five subjects in Colorado between the ages of 37 to 79 completed an electrohypersensitivity (EHS) questionnaire. After recording their orthostatic HRV, we did continuous real-time monitoring of HRV in a provocation study, where supine subjects were exposed for 3-minute intervals to radiation generated by a cordless phone at 2.4 GHz or to… 

Original Findings Confirmed in Replication Study: Provocation with 2.4 GHz Cordless Phone affects the Autonomic Nervous System (ANS) as measured by Heart Rate Variability (HRV)

This is a double-blind, placebo-controlled replication of a study that we previously conducted in Colorado with 25 subjects designed to test the effect of radio frequency radiation (RFR) generated by

Heart rate variability affected by radiofrequency electromagnetic field in adolescent students

Short‐term RF EMF exposure of students in a lying position during the ortho‐clinostatic test affected ANS with significant increase in parasympathetic nerve activity compared to sham exposed group.

Evaluation of heart rate variability, blood pressure and lipid profile alterations from dual transceiver mobile phone radiation exposure

Exposure to electromagnetic radiation from dual transceiver mobile phones could be a risk factor to increase in blood pressure, heart rate variability, blood pressure and lipid profile in Wistar rats exposed to electromagnetic field radiation from a dual trans receiver mobile phone.

Provocation studies presented in this article demonstrate that the response to electrosmog is physiologic and not psychosomatic, and those who experience prolonged and severe EHS may develop psychologic problems as a consequence of their inability to work, their limited ability to travel in the authors' highly technologic environment, and the social stigma.

Do people with idiopathic environmental intolerance attributed to electromagnetic fields display physiological effects when exposed to electromagnetic fields? A systematic review of provocation studies

There is no reliable evidence to suggest that people with IEI-EMF experience unusual physiological reactions as a result of exposure to EMF, which supports suggestions that EMF is not the main cause of their ill health.

The influence of Wi-Fi range electromagnetic radiation on the parameters of the human’s heart variability

The index of the regulatory systems’ tension increases during the combined influence of WFR and psycho emotional load, ipso facto,ating the adequate regulatory reaction of the body towards the decrease of the adaptive abilities.

Change in pulse rate with Enviro Chip and dummy chip fixed on radiation emitting devices like mobile phones/computers/laptops of users—A double blind crossover study *

The study demonstrated statistical significant reduction in pulse rate over 14 measurements with the use of Enviro Chip in both male and female healthy volunteers.

Diplomats' Mystery Illness and Pulsed Radiofrequency/Microwave Radiation

Whether pulsed radiofrequency/microwave radiation (RF/MW) exposure can accommodate reported facts in diplomats, including unusual ones, appears consistent with pulsed RF/MW as the source of injury in affected diplomats.

Brain proteome response following whole body exposure of mice to mobile phone or wireless DECT base radiation

Comparative proteomics analysis revealed that long-term irradiation from both EMF sources altered significantly the expression of 143 proteins in total, which may be related to brain plasticity alterations, indicative of oxidative stress in the nervous system or involved in apoptosis and might potentially explain human health hazards reported so far.



Electromagnetic fields produced by GSM cellular phones and heart rate variability

The analysis of the data show there was no statistically significant effect due to EMF exposure both on main (i.e., RR mean) and most of the other HRV parameters, and a weak interaction between someHRV parameters and RF exposure was observed.

Cardiac autonomic activity during sleep under the influence of radiofrequency electromagnetic fields

Under the given experimental conditions, no influence of weak radiofrequency electromagnetic fields on cardiac autonomic activity could be proven.

Provocation study of persons with perceived electrical hypersensitivity and controls using magnetic field exposure and recording of electrophysiological characteristics.

Analysis of possible neurophysiological effects of intermittent 15 sec on/off cycle, 60 Hz, 10 microT magnetic field exposure on patients with perceived "electromagnetic hypersensitivity" (EHS), and control subjects during rest and performance of a mental arithmetic task indicates EHS patients have a rather distinctive physiological predisposition to sensitivity to physical and psychosocial environmental stressors.

No Effects of Pulsed High-Frequency Electromagnetic Fields on Heart Rate Variability during Human Sleep1

Under the given experimental conditions, autonomic control of heart rate was not affected by weak-pulsed high-frequency electromagnetic fields and the autonomic balance was shifted in favor of the sympathetic activity.

Alteration of diurnal rhythms of blood pressure and heart rate to workers exposed to radiofrequency electromagnetic fields.

Healthy men aged 28-49 years, working on a pattern of 12-24-12-48 h, exhibited typical, well-preserved diurnal rhythms of blood pressure and heart rate with two maxima and one minimum and changes were more pronounced among workers exposed to high intensities of radiofrequency EMF.

Psychophysiological tests and provocation of subjects with mobile phone related symptoms.

The cases displayed a shift in low/high frequency ratio towards a sympathetic dominance in the autonomous nervous system during the CFFT and memory tests, regardless of exposure condition, which might be interpreted as a sign of differences in theonomous nervous system regulation between persons with MP related subjective symptoms and persons with no such symptoms.

The influence of the call with a mobile phone on heart rate variability parameters in healthy volunteers.

It was shown that the call with a mobile phone may change the autonomic balance in healthy subjects and changes in heart rate variability could be affected by electromagnetic field but the influence of speaking cannot be excluded.

Electromagnetic pulses induce fluctuations in blood pressure in rats

Significant alterations in arterial blood pressure were observed in rats exposed to EMP exposure while heart rate was not altered, and the heart rates in sham- and EMP-exposed rats were not significantly changed.
