Finnish researchers surveyed over 6,000 working adults about accidents and near-miss situations involving mobile phone use. They found that 13.7% experienced close calls and 2.4% had actual accidents during leisure time where mobile phones played a role, with lower rates at work. Men, younger people, and those reporting sleep problems or minor aches showed higher accident rates while using phones.

Researchers surveyed 75 people in Japan who reported electromagnetic hypersensitivity (EHS), a condition where individuals experience symptoms they attribute to EMF exposure from devices like cell phones and base stations. The study found that 85% reported severe fatigue, 81% experienced memory and concentration problems, and many had to make major life changes including job loss and relocating to avoid EMF sources. Most participants (65%) reported feeling sick from other people's mobile phones on public transportation, highlighting the profound social and economic impacts of this condition.
Bortkiewicz A et al. · 2012
Polish researchers surveyed 500 households living near cell phone towers to assess health symptoms and their relationship to EMF exposure. They found that 57% of residents reported headaches, with the highest rates occurring in people living 100-150 meters from towers, while memory problems were most common in those living farther away. Surprisingly, symptom frequency didn't correlate with measured electric field strength, suggesting current exposure assessment methods may be inadequate.

Researchers analyzed 63 studies to understand how scientists identify people who report being hypersensitive to electromagnetic fields (EMF). They found that researchers use wildly different criteria to define EMF hypersensitivity, making it nearly impossible to compare studies or understand the true scope of the condition. The lack of standardized identification methods creates confusion in both research and clinical practice.

Polish researchers exposed rats to cell phone-frequency electromagnetic fields (1500 MHz and 1800 MHz) for 15 minutes and tested how well the painkiller tramadol worked afterward. While the EMF exposure alone didn't change pain sensitivity, it significantly reduced tramadol's pain-relieving effects when the two were combined. This suggests that EMF exposure from devices like cell phones might interfere with how certain medications work in the body.

Swiss researchers reviewed studies examining whether wireless communication radiation causes non-specific health symptoms like headaches, fatigue, and concentration problems. Most randomized trials and observational studies found no consistent connection between RF-EMF exposure from cell phones, base stations, and other wireless sources and these symptoms. The review also found no evidence that people claiming electromagnetic hypersensitivity are more susceptible to wireless radiation than others.
Unknown authors · 2011
This 2012 review examined electromagnetic hypersensitivity (EHS), a condition where people report debilitating symptoms from exposure to wireless devices and electrical equipment. The authors found the scientific literature on EHS is sparse, with ongoing debate about whether the condition is physiological or psychological. The review highlighted that EHS patients face significant social challenges and impaired quality of life, regardless of the underlying mechanism.

This 2011 literature review examined studies on radiofrequency electromagnetic fields from wireless devices and their connection to non-specific health symptoms like headaches and fatigue. The analysis of multiple randomized trials and observational studies found no consistent pattern linking RF-EMF exposure to health-related quality of life issues. The research also showed that people claiming electromagnetic hypersensitivity were not more susceptible to RF-EMF than the general population.

This 2011 systematic review examined whether radiofrequency radiation from wireless devices like cell phones and base stations causes non-specific health symptoms. Analyzing multiple randomized trials and observational studies, researchers found no consistent pattern linking RF exposure to symptoms like headaches or fatigue. The authors concluded that current research doesn't show wireless communication fields affecting health-related quality of life in everyday environments.

Researchers exposed 20 people (10 who claimed electromagnetic hypersensitivity and 10 who didn't) to smartphone radiofrequency radiation at 1950 MHz for 30 minutes in a controlled, double-blind study. They monitored heart and breathing patterns during exposure but found no measurable changes in either group. This suggests that short-term smartphone RF exposure at typical levels doesn't immediately affect basic cardiovascular or respiratory functions.

German researchers equipped over 3,000 children and teens with personal radiation meters for 24 hours to measure their actual exposure to radiofrequency electromagnetic fields from cell phones and other wireless devices. They then looked for connections between measured exposure levels and chronic symptoms like fatigue and headaches. The study found no statistically significant link between RF exposure and health complaints, with all measured exposure levels falling far below international safety guidelines.

Swedish researchers followed over 4,000 young adults for one year to examine whether mobile phone use patterns affect mental health. They found that heavy phone users were more likely to experience stress, sleep problems, and depression symptoms, with the strongest effects among those who felt pressured to always be accessible. The study suggests that how we use our phones psychologically matters as much as how often we use them.
Thomée S, Härenstam A, Hagberg M. · 2011
Swedish researchers followed over 4,000 young adults for one year to examine how mobile phone use affects mental health. They found that heavy phone users were significantly more likely to develop stress, sleep problems, and depression symptoms compared to light users. The strongest predictor wasn't just frequency of use, but feeling stressed about being constantly accessible through their phone.
Mortazavi SM et al. · 2011
Researchers tested whether people who claim to be sensitive to cell phone radiation can actually detect when they're being exposed to it. They studied 20 university students who reported electromagnetic hypersensitivity, exposing them to real and fake cell phone radiation while monitoring their vital signs. Only 25% could tell the difference between real and fake exposure (no better than random chance), and their heart rate, breathing, and blood pressure showed no changes during actual radiation exposure.
Baliatsas C et al. · 2011
Dutch researchers studied 3,611 adults living near cell towers and power lines to understand what causes non-specific physical symptoms like headaches and fatigue. They found that people's belief about how close they lived to these sources predicted symptoms better than the actual measured distance. The study suggests psychological factors and perceived risk may play a larger role in these health complaints than the electromagnetic fields themselves.
McCarty DE et al. · 2011
Scientists tested a doctor claiming electromagnetic hypersensitivity using 60 Hz electric fields in a double-blind study. She developed headaches, muscle twitching, and heart irregularities within 100 seconds of exposure, proving electromagnetic hypersensitivity can be a measurable neurological condition.

Researchers tested whether TETRA radio signals used by UK police and emergency services cause health symptoms in people who report electromagnetic sensitivity. In double-blind conditions, neither sensitive individuals nor controls could detect the signal or showed any physical or subjective health effects. However, when participants knew they might be exposed, the sensitive group reported feeling worse, suggesting symptoms stem from expectation rather than the EMF exposure itself.
Unknown authors · 2010
Researchers tested whether TETRA police radio base station signals cause health symptoms in 51 people claiming electromagnetic sensitivity and 132 controls. Under double-blind conditions, neither group could detect the signal or showed any physical or subjective health differences between real and fake exposures. The study concluded that reported symptoms stem from belief rather than actual electromagnetic exposure.

Researchers reviewed 17 studies examining whether cell phone towers cause health symptoms in people living nearby. They found that well-designed laboratory studies showed no connection between tower radiation and acute symptoms, while studies with less precise measurement methods were more likely to report effects. The review concluded there's strong evidence that cell tower radiation up to 10 volts per meter doesn't cause immediate symptoms, but insufficient data exists on long-term health effects.

German researchers used personal dosimeters to measure radiofrequency radiation exposure in nearly 3,000 children and adolescents over 24 hours, then tracked acute symptoms like headaches and concentration problems. While they found a few statistically significant associations between higher RF exposure and symptoms, the researchers concluded these were likely due to chance rather than actual health effects because the results weren't consistent and disappeared when analyzing the highest-exposed participants separately.
Khurana VG et al. · 2010
Researchers analyzed 10 studies examining health effects in people living near cell phone towers (base stations). They found that 8 out of 10 studies reported increased rates of neurological symptoms or cancer in populations living within 500 meters (about 1,600 feet) of these towers. Importantly, all exposures were below current safety guidelines, suggesting these standards may not adequately protect public health.
Johansson A, Nordin S, Heiden M, Sandström M. · 2010
Researchers compared 116 people who reported symptoms from mobile phones or general electromagnetic hypersensitivity (EHS) with control groups to understand their psychological profiles. They found that people with mobile phone-specific symptoms showed higher rates of exhaustion and depression, while those with general EHS showed elevated anxiety, depression, and other psychological symptoms. The study suggests these represent two distinct conditions that may require different treatment approaches.

German researchers used personal dosimeters to measure radiofrequency electromagnetic field exposure in nearly 3,000 children and adolescents over 24 hours, then tracked acute symptoms like headaches and concentration problems. They found a few statistically significant associations between higher RF exposure and symptoms, but these results were inconsistent and disappeared when analyzing the highest-exposed participants. The researchers concluded the observed effects likely occurred by chance rather than representing true causal relationships.
Nam KC, Lee JH, Noh HW, Cha EJ, Kim NH, Kim DW. · 2009
Researchers tested 18 people who claimed to be sensitive to electromagnetic fields (called EHS or electromagnetic hypersensitivity) against 19 people without such sensitivity, exposing both groups to real and fake cell phone radiation for 30 minutes. Neither group showed any measurable physical changes or symptoms from the actual radiation exposure, and the supposedly sensitive people couldn't tell the difference between real and fake exposure any better than the control group.
Furubayashi T et al. · 2009
Researchers exposed 54 women (including 11 with self-reported electromagnetic hypersensitivity) to cell tower radiation at 10 V/m for 30 minutes in a controlled lab setting. Neither group could detect when they were actually being exposed to EMF, and both groups showed identical biological responses whether exposed to real or fake radiation. The study found no evidence that people with electromagnetic hypersensitivity react differently to cell tower emissions than healthy controls.
