Wardzinski EK et al. · 2022
Researchers exposed 15 young men to mobile phone radiation for 25 minutes, then measured their food consumption at a buffet. Participants ate 22-27% more calories after phone exposure compared to fake exposure, mainly from increased carbohydrate intake. Brain scans showed the radiation altered brain energy metabolism.

Researchers tracked radiofrequency electromagnetic field (RF-EMF) exposure from phones, tablets, and other devices in nearly 1,900 children aged 9-12 years, measuring their sleep patterns with wrist monitors for a week. Children with high evening phone call exposure slept about 12 minutes less per night compared to those with no evening phone exposure. The study couldn't determine whether the sleep disruption came from the RF-EMF radiation itself or from the stimulating activities that prompted the phone calls.
Srujana Aravinda VS et al. · 2022
Researchers examined mouth cells from 90 children divided into three groups based on daily mobile phone use (1-2 hours, 3-6 hours, and over 6 hours). Children using phones more than 6 hours daily showed significantly more cellular damage and chromosomal abnormalities in their mouth tissue. The study focused on increased screen time during COVID-19 online learning.
Hassanzadeh-Taheri M et al. · 2022
Researchers exposed healthy sperm samples to active cell phone radiation for 60 minutes at close range (2.5 cm) and compared them to control samples exposed to inactive phones. The cell phone radiation significantly reduced sperm viability and movement while increasing DNA damage and cell death. This laboratory study demonstrates that radiofrequency radiation from phones can harm sperm quality even in short exposures.
Ding Z, Xiang X, Li J, Wu S · 2022
This study exposed mouse Balb/c-3T3 cells to 1800 MHz radiofrequency electromagnetic radiation for 40-60 days and observed signs of malignant transformation, including increased cell proliferation, migration, visible foci formation, and tumor development when transplanted into SCID mice. The researchers identified lipid metabolism and the mevalonate pathway as key biological processes involved in the observed cellular changes.
Costantini E et al. · 2022
This 2022 in vitro study investigated how radiofrequency electromagnetic field (RF-EMF) exposure affects wound healing by examining keratinocyte migration and expression of genes involved in the healing process. The researchers found that RF-EMF treatment promoted keratinocyte migration and regulated expression of matrix metalloproteinases, their inhibitors, and inflammatory cytokines in ways that appeared to support wound healing.
Aravinda VSS et al. · 2022
Researchers examined mouth cells from 90 children divided into three groups based on daily mobile phone use (1-2 hours, 3-6 hours, and over 6 hours). Children using phones more than 6 hours daily showed significantly more cellular damage and chromosomal abnormalities. The study focused on increased screen time during COVID-19 online education.
Pagadala, P; Shankar, V and Sumathi, ME · 2022
This study examined the effects of radiofrequency electromagnetic radiation (RFEMR) from mobile phones on neuron-specific enolase (NSE) and malondialdehyde (MDA) levels in male Sprague Dawley rats. The researchers found significant increases in both NSE and MDA levels in rats exposed to RFEMR, suggesting that mobile phone radiation causes oxidative stress and oxidative damage.

Bansal D et al. · 2022
Researchers studied 81 students to see how different amounts of daily mobile phone use affected their saliva. They found that people who used phones more than 60 minutes daily had higher levels of malondialdehyde (a marker of cellular damage) in their saliva compared to moderate users, suggesting increased oxidative stress from longer phone exposure.
Isabel López et al. · 2021
Spanish researchers surveyed 268 residents living near nine cell phone towers in Madrid and measured electromagnetic radiation levels in their homes. People exposed to higher radiation levels experienced significantly more headaches, nightmares, dizziness, and sleep problems. The neighborhood also showed cancer rates 10 times higher than the Spanish national average.
Baaken D, Dechent D, Blettner M , Drießen S , Merzenich H · 2021
Researchers examined 15 studies linking workplace exposure to extremely low-frequency magnetic fields (like those from power lines and electrical equipment) with amyotrophic lateral sclerosis (ALS), a fatal neurological disease. The analysis found these studies were too different in methods to draw firm conclusions, but showed enough promise to justify a major pooled study. Eight research teams agreed to share their original data for better analysis.
Akakin D et al. · 2021
Researchers used EEG brain wave measurements to study how mobile phone electromagnetic radiation affects brain activity in real-time. They compared brain wave patterns when participants were not using phones versus when actively using them. The study found measurable changes in brain electrical activity during mobile phone use, suggesting the radiofrequency energy does influence neural function.
Dalecki A, Verrender A, · 2021
This study examined how methodological factors influence the detection of radiofrequency electromagnetic field (RF-EMF) effects on EEG alpha power in 36 adults exposed to sham, low, and high RF-EMF conditions. The researchers found that alpha power increases were greater during eyes-open versus eyes-closed EEG recordings and showed a trend toward larger increases later in the exposure period, suggesting that previous studies using eyes-closed conditions or shorter exposure durations may have failed to detect RF-EMF effects.
Unknown authors · 2021
European researchers studied over 3,200 children and teens to measure radiofrequency radiation doses to their brains from phones, tablets, and other wireless devices. They found that higher brain radiation exposure was linked to lower non-verbal intelligence scores in 9-11 year olds. The effect was small but consistent across multiple countries.
Bueno-Lopez A et al. · 2021
Researchers exposed 30 young men to Wi-Fi radiation (2.45 GHz) all night while they slept to test effects on memory formation. Surprisingly, participants performed slightly better on word memory tasks after Wi-Fi exposure, though brain activity measurements showed no changes. The authors suggest this unexpected finding may be random rather than meaningful.

This study exposed four-week-old mice to 1800 MHz radiofrequency fields for three weeks during morning and evening periods to investigate effects on testicular development. The exposure resulted in decreased testicular weight, sperm production, and testosterone levels, along with dysregulation of long non-coding RNA expression, with morning exposure affecting 615 lncRNAs compared to 183 for evening exposure.
Unknown authors · 2021
Researchers exposed blood cells from 5 men to 900 MHz cell phone frequency radiation for up to 90 minutes, analyzing changes in 667 microRNAs that regulate gene expression. While they initially found 2 microRNAs that appeared to respond to EMF exposure, these changes could not be reproduced when the experiment was repeated 2 years later. The study found no consistent evidence that brief 900 MHz exposure alters microRNA expression in human blood cells.

Ghandehari M, Sadri D, Farhadi S · 2021
Iranian researchers examined 100 people's cheek cells and found that heavier cell phone users had significantly more micronuclei - tiny fragments that indicate DNA damage. The study showed a strong correlation (r = 0.70) between daily phone usage and cellular damage markers in mouth tissue.
Fahmi A et al. · 2021
Egyptian researchers studied 100 men divided by cell phone usage patterns and found that heavy users (more than 1 hour daily for over 5 years) had significantly lower testosterone and higher stress hormones compared to light users. The effects were most pronounced in men using phones over 3 hours daily for more than 15 years, suggesting cumulative damage to male reproductive health from long-term cell phone radiation exposure.
Akakin D et al. · 2021
Researchers measured brain wave activity using EEG tests to determine if mobile phone electromagnetic radiation affects brain function. They compared brain activity when participants were not using phones versus when actively using them. This study examined whether the radiofrequency energy absorbed by your head during phone calls creates measurable changes in neural activity.

Estimated whole-brain and lobe-specific radiofrequency electromagnetic fields doses and brain volumes in preadolescents Alba Cabré-Riera et al. · 2020
Dutch researchers studied 2,592 children aged 9-12 to see if radiofrequency radiation from phones, tablets, and WiFi affected their brain structure using MRI scans. They found no association between RF exposure and overall brain volumes, but children with higher exposure from internet-connected devices had slightly smaller caudate brain regions. The researchers noted this finding might reflect lifestyle factors rather than radiation effects.
