An epidemiological investigation in Sweden and Norway observed a statistically significant lower risk for sensations of warmth on the ear for GSM users compared with NMT 900 users, and the same trend was seen in Norway for sensation of warmth behind/around the ear and in Sweden for headaches and fatigue.
Skin symptoms after the reduction of electric fields from visual display units.
The hypothesis that facial skin symptoms can be reduced by decreasing static and low-frequency electric fields produced by visual display units is weakly supported.
Symptoms experienced in connection with mobile phone use.
A cross-sectional epidemiological study among 17,000 people using an MP in their job suggests an awareness of the symptoms, but not necessarily a serious health problem.

There is no reliable evidence to suggest that people with IEI-EMF experience unusual physiological reactions as a result of exposure to EMF, which supports suggestions that EMF is not the main cause of their ill health.

The study gave no evidence that RF fields from mobile phones may cause head pain or discomfort or influence physiological variables, and found the most likely reason for the symptoms is a nocebo effect.
IEI‐EMF provocation case studies: A novel approach to testing sensitive individuals
The present experiment failed to show a relationship between RF- EMF exposure and an IEI-EMF individual's symptoms.

Evaluated methodological limitations in experimental studies on symptom development in IEI-EMF individuals that might have fostered false positive or false negative results indicated that an effect of exposure is unlikely and researchers are encouraged to achieve a high credibility of the results by minimizing sources of bias and imprecision.
Skin temperature increase caused by a mobile phone: A methodological infrared camera study
The insulation and the electrical power dissipation led to statistically significant rises in the skin temperature, while the RF exposure did not, and the study was designed as a double blind experiment.
Long-term effects on symptoms by reducing electric fields from visual display units.
The hypothesis that skin, eye, or nervous system symptoms can be reduced by reducing VDU electric fields does not support the hypothesis.
ICNIRP Statement on Diagnostic Devices Using Non-ionizing Radiation: Existing Regulations and Potential Health Risks
Review of the epidemiological evidence concerning health risks associated with exposure to diagnostic NIR highlighted a lack of data on potential risks to the fetus exposed to MRI during the first trimester, and on long-term health risks in workers exposed toMRI.
