Complications of nonionizing radiofrequency on divided attention

Abstract

Complications of nonionizing radiofrequency on divided attention Bamdad K, Adel Z, Esmaeili M. Complications of nonionizing radiofrequency on divided attention. J Cell Biochem. 2019 Feb 3. doi: 10.1002/jcb.28343. Abstract Exposure to electromagnetic fields is considered as a potential hazard for biological systems. The objective of our investigation is the study of probable consequences of radiofrequency electromagnetic fields from Wi-Fi router devices on the short-term memory, and attention's levels. A population consisting of 312 female college students (14 to 17 years old) was elected by cluster random sampling. Teenagers were divided into two groups of control group (Wi-Fi nonusers; n = 138), and experiment group (Wi-Fi users; n = 174). Both groups have been examined using short-term memory tests; selective attention, and also divided attention tests. According to the results, there was no significant difference between using Wi-Fi router devices on levels of selective attentions and short-term memory of the sample students with the control group. However, analyses revealed that there is a significant correlation between the use of Wi-Fi routers and declining levels of divided attentions. Our investigation has demonstrated the adverse consequences of 2.4-2.48 GHz radiofrequency electromagnetic fields of Wi-Fi router devices on divided attention levels of female university students that should be mentioned as a technological risk factor and taken into account by healthcare organizations. ncbi.nlm.nih.gov Note: This was an observational study, not a randomized trial. The observed difference on divided attention may be due to confounding.

Main findings

In 312 female students (Wi‑Fi nonusers n=138; Wi‑Fi users n=174), no significant differences were reported for selective attention or short-term memory between groups. A significant correlation was reported between Wi‑Fi router use and lower divided attention levels.

Outcomes measured

• short-term memory
• selective attention
• divided attention

Limitations

• Observational (non-randomized) design; potential confounding noted in the provided text
• Exposure characterization limited to Wi‑Fi router use; no quantitative exposure metrics reported

Suggested hubs

• school-wi-fi (0.9)
  Study evaluates Wi‑Fi router exposure in students and cognitive/attention outcomes.
