From street-level measurements to long-term health studies, researchers are building a clearer picture of the impact of everyday exposure to 5G signals on human health.
Measurements across multiple European countries indicate that everyday exposure to 5G radiofrequency electromagnetic fields remains well below international safety limits. Short-term laboratory studies found no measurable effects on heart function, stress, skin temperature, or brain activity in healthy adults exposed to 3.5 GHz 5G signals. Ongoing research is examining long-term health and behavioural impacts.
More than 800 measurements were taken across urban and rural locations in eight EU countries, plus Switzerland and the UK. The team looked at scenarios from phones in flight mode to data-intensive activities, such as sharing attachments or watching livestreamed video.
The results show that exposure to RF-EMF in everyday environments remains well below international safety limits in all settings measured.
These limits, set by independent scientific bodies, define the maximum exposure levels considered safe for the general public and include large safety margins.
To investigate whether 5G signals have any immediate effects on the body, researchers in France have carried out the first coordinated human laboratory studies focusing on a key 5G frequency band: 3.5 gigahertz.
At INERIS, the French National Institute for Industrial Environment and Risks near Paris, 31 healthy volunteers were exposed to 5G signals for 26 minutes under controlled conditions designed to reflect real-world environmental exposure.
They observed no measurable impact on heart function, stress levels, skin temperature or brain activity in healthy young adults.
However, the researchers stress that the phone doesn't only bring radio frequency electromagnetic fields exposure. It also brings screen light exposure, mental arousal or device dependency.
