Physical activity as an option to reduce adverse effect of EMF exposure during pregnancy

Abstract

The popularity of using wireless fidelity over the last decades increased apprehensions about impact of high frequency electromagnetic fields (EMF) on health. Most of previous studies mentioned adverse effect of EMF on cognitive processes, but so far, no study has provided a way to control adverse effects of EMF exposure. The purpose of this study was to examine the effect of Wi-Fi EMF and physical activity on spatial learning and motor function in pregnant rat's offspring. Forty Albino-Wistar pregnant rats divided randomly into four groups (EMF, physical activity, combined 2.4GHZ EMF and physical activity and control groups). For assessing spatial learning in 56 post-natal days' old (PND) male offspring, Morris Water Maze (MWM) was used and to examine motor function Open-field test was taken. Although results of MWM test revealed that Wi-Fi modem EMF caused impairment in spatial learning in rats exposed to EMF but physical activity could reduce negative effect of EMF in pregnant rat's offspring who exposed during pregnancy but performed swimming. In addition, results of open-field test showed that litter's motor function in EMF group significantly declined in comparison with physical activity and combined 2.4GHZ EMF and physical activity groups. According to our findings, it can be concluded that execution physical activity individually or along with wave-exposed pregnancy can significantly progressive effect on offspring' cognitive and motor functions.

A primary study on rat fetal development and brain-derived neurotrophic factor levels under the control of electromagnetic fields

“…Each group was exposed to a cycle of 12 hours of light and 12 hours of dark. 29 After delivery, 12 male neonates from EMF and CON maternal groups were randomly selected for the experiment using a simple randomization approach. Helsinki ethics were applied in this research.…”

“…From the first day to the day of delivery, between 8 a.m. and 2 p.m., pregnant rats were exposed to EMF waves, 2.4 GHz, during the download or upload of various files. 29 As previously mentioned, during radiation, the control group was kept in the shielded room. The specific absorption rate (SAR) was determined using the mathematical Finite Difference Time Domain formula:…”

“…8 For instance, prior investigations have claimed that EMF has caused some issues: reproductive disorders, memory deficits, cancer, hyperactivity, etc . 1 , 9-11 In contrast, other studies have often discounted the withering effects of EMF exposure. 12-14 However, none of them have considered the effect of EMF exposure on human growth, nor have they examined anthropometric measurements to document such effects.…”
