Plain English Summary
Researchers exposed pregnant and newborn female rats to WiFi-frequency radiation (2450 MHz) for one hour daily and tracked their development through puberty. Rats exposed in the womb showed slower growth, delayed puberty, and increased oxidative stress in brain and ovary tissues compared to unexposed controls. This suggests that WiFi radiation during critical developmental periods may disrupt normal reproductive maturation.
Why This Matters
This study adds concerning evidence to the growing body of research on EMF effects during critical developmental windows. The 2450 MHz frequency used is identical to what your WiFi router emits, making these findings directly relevant to modern households where pregnant women and children are continuously exposed. What makes this research particularly significant is its focus on prenatal exposure - the most vulnerable period when developing organ systems are establishing their basic architecture. The fact that just one hour of daily exposure during pregnancy led to measurable developmental delays and tissue damage in offspring should give us pause about our casual acceptance of ubiquitous wireless technology in homes and schools. While we can't directly extrapolate animal studies to humans, the biological mechanisms observed here - oxidative stress in reproductive and brain tissues - are well-established pathways for EMF harm across species.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 2450 MHz Duration: 1 h/day
Study Details
The aim of this study was to investigate the effects of a 2450 MHz electromagnetic field (EMF) (wireless internet frequency) on the growth and development of female Wistar rats.
The study was conducted on three groups of rats. The prenatal and postnatal groups were exposed to E...
Birth masses of the groups were similar (p > 0.05). Mass gain per day was significantly lower and th...
This is the first longitudinal study which investigates the effects of EMF induced by wireless internet on pubertal development beside growth.
