“[W]e uncovered a causal relationship between 2.4 GHz EMR modulated by 100-Hz square pulses and increased wakefulness in mice. This result identifies sleep alteration as a potential consequence of exposure to excessive wireless signals.”
It’s worth noting that a 1976 Defense Intelligence Agency (DIA) report noted that military personnel “exposed to non-thermal microwave radiation were said to have experienced ... sleeplessness ... for frequencies between 2.05-2.50 GHz.” This was cited by the NAS-NRC committee in its 2020 report on the Havana Syndrome.
