For better communication, constant use of mobile phone is a common practice due to various low-priced free voice calling and internet facility given by telecommunication companies. Various studies indicated that the electromagnetic radiation from a mobile phone can be extremely detrimental, causing headache, dizziness, numbness in thigh, genetic damage, cancer, memory loss, increased blood pressure and weakening defense mechanism of body. The electromagnetic radiation emitted by mobile phone is invisible, vague, and enters and leaves our body. Present study deals with effect of radiation emitted by smart mobile phone on heart rate variability and changes in blood pressure on ten young volunteers. The experiment was conducted in a laboratory using ECG machine and BP monitor on young and healthy volunteers of age group 22-24 years. New Jio phones with head SAR 0.6 W/kg and body SAR 0.65 W/kg with 4G LTE connectivity were used as transmitter and receiver. Receiver and transmitter mobile phones were kept near mouth-head position. The period of communication was 15, 30 and 45 minutes continuously. Electrocardiograms were recorded by BPL machine having limb and chest electrodes. Electrodes were used to record the electrocardiogram (ECG) as per standard practice used in hospitals and guidelines supplied by BPL Company. Digital blood pressure monitor notices subject’s blood movement through branchial artery which converts the movements of blood into a digital form. The model SEM-1 of Omron Company was used to record systolic and diastolic blood pressure for same intervals as mentioned above. The results indicated changes in both parameters when mobile phone was kept close to head, but the changes cannot be considered significant at p <.05 despite of noticeable changes in parameters. Furthermore, it is important to correlate such study with electrical activities of the brain recorded during use of mobile phone. The results obtained from such studies should be communicated to the user in a transparent and differentiated way.
