Triple-blind study finds no short-term heart effects from 26 GHz 5G exposure
"Analysis revealed no statistically significant differences across time- or frequency-domain HRV parameters between real and sham exposures at any phase of exposure."
"Still, as the exposure duration was relatively brief and the population limited to healthy young individuals, further studies are needed to investigate longer exposures, potential effects during autonomic modulation such as orthostatic maneuvers, and responses in more diverse or vulnerable groups."
"However, these findings contribute valuable information indicating that no measurable acute physiological changes were observed under the specific environmental exposure conditions investigated; these findings do not address possible long-term or cumulative effects."
Exposure
"Using a triple-blind, randomized crossover design, 31 participants were exposed to both real and sham 26 GHz 5 G new radio modulated radiofrequency fields in a controlled, shielded environment. Exposure levels were set to reflect realistic upper environmental values (2 V/m at the head and 1 V/m at the torso)."
