"Environmental-level 26 GHz exposure does not produce detectable acute effects on sympathetic nervous system activity as measured through electrodermal responses."
"These findings contrast with reported effects at lower 5 G frequencies, suggesting frequency-specific biological interactions."
"Results support current guidelines yet emphasize the need for complementary study."
Exposure
"Participants underwent two sessions (real and sham exposure) with electric field intensities of 2 V/m at head level and 1 V/m at torso level, representing upper environmental exposure ranges [for] 25.5 min"
