Abstract

The rapid increase in the use of mobile phones (MPs) in recent years has raised the problem of health risk connected with high-frequency electromagnetic fields. There are reports of headache, dizziness, numbness in the thigh, and heaviness in the chest among MP users. This paper deals with the neurological effect of electromagnetic fields radiated from MPs, by studies on heart rate variability (HRV) of 14 male volunteers. As heart rate is modulated by the autonomic nervous system, study of HRV can be used for assessing the neurological effect. The parameters used in this study for quantifying the effect on HRV are scaling exponent and sample entropy. The result indicates an increase in both the parameters when MP is kept close to the chest and a decrease when kept close to the head. MP has caused changes in HRV indices and the change varied with its position, but the changes cannot be considered significant as the p values are high.

摘要

近年来，手机使用的迅速增加引发了与高频电磁场相关的健康风险问题。有报道称手机用户出现头痛、头晕、大腿麻木和胸部沉重等症状。本文通过对14名男性志愿者的心率变异性（HRV）进行研究，探讨了手机辐射电磁场的神经学效应。由于心率受自主神经系统调节，因此对HRV的研究可用于评估神经学效应。本研究中用于量化对HRV影响的参数是标度指数和样本熵。结果表明，当手机靠近胸部时，这两个参数均增加；当靠近头部时，则降低。手机导致了HRV指标的变化，且这种变化随其位置而不同，但由于p值较高，这些变化不能被认为具有显著性。
