Background

The Cell phones are a major part of people's lives in contemporary societies. Might their radiation be able to affect some cognitive functions while people drive? This study aims to investigate the effect of cell phone radiation on the brain’s cognitive functions.

Materials and Method

 Forty female students without depression or anxiety volunteered in the cross-sectional study. During one session, the volunteers were randomly exposed to cell phone radiation (20 participants in the first and 20 participants in the second). Participants performed four cognitive tests in each session. A p-value of less than 0.05 was taken as the cut-off point to consider a statistically significant result.

Results

 In the congruent part of the Stroop test, the reaction time (RT) was reduced in both groups during the time volunteers were exposed to radiation and there were significant differences between sessions in both groups (P=0.005 and P<0.001). These differences were significant between the two groups in different sessions. However, the number of errors decreased during exposure to radiation and this difference was significant in the first group (P=0.015). In the incongruent part of the Stroop test, the treatment showed that the radiation of mobile phones had a significant effect on the reduction of RT (P<0.001).

Conclusion

 Based on this study, it seems that cell phone radiation waves have a limited effect on RT, cognitive and executive function. Therefore, traffic accidents that occur during a mobile phone conversation might be solely due to the division of attention rather than a direct effect of cell phone waves.
