An Observational Study of Effect of Mobile Phone Radiation on Heart Rate Variability
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 3
Abstract
Introduction: Mobile phone technology revolution has resulted in a high-frequency electromagnetic environment which has resulted in a spectrum of potential health hazards. The effects of this widespread electromagnetic radiation (EMR) directly on autonomic tone of the body and thereby indirectly on modifying the functions of cardiovascular functions remains understudied. Studies have confirmed that autonomic system influences the beat to beat variability of heart rate and so heart rate variability (HRV) analysis is considered to be an independent predictor of cardiovascular risk. And so, this study was designed to measure the effects of electromagnetic waves emitted by mobile phones and Bluetooth on cardiac autonomic modulation by heart rate variability (HRV) analysis. Materials and Methods: ECG recording and HRV analysis were done for 200 healthy male and female volunteers aged between 18-25 years using Student Physiograph and Analogue to Digital Convertor. Time Domain Analysis Parameters and Frequency Domain Analysis Parameters were observed for mobile call usage -test I and Bluetooth usage -Test II. Results: There was a significant increase in the heart rate which indicated an increase in sympathetic tone on mobile phone and Bluetooth device usage. Paired “t” test showed statistically significant value of 0.003 and 0.009 (P<0.05) for mean MRR only, while the rest of the parameters studied exhibited considerable differences in between all the three pairs. Conclusion: This study shows an impact of the hazardous effect of EMR emitted by mobile phones and Bluetooth devices on cardiovascular activity. With a sharp rise on mobile phone and Bluetooth users, it is very much essential to create awareness among the individuals regarding the hazardous effects of radiation emitted by these devices/gadgets so as to reduce the usage of the same and to undertake some safety measures.
