The radiation case is empty. Sleep labs have run the same test for thirty years: put someone in bed, run a real or fake phone signal through the night, score the sleep. People can't tell active nights from sham nights, and the sleep stages don't move 1. A European Commission review of the whole pile reached the same verdict 2.
The dose isn't there. Radio photons carry about a million times too little energy to break a chemical bond, so they can't damage DNA the way an X-ray can. The one confirmed effect is heating, and a router across the room warms nothing you could measure 3. IARC's "possibly carcinogenic" tag came from heavy users pressing a phone to their head for years โ the same weak tier as pickled vegetables, and not from nightstand distance 4.
What crushes melatonin is the screen, not the antenna. Four hours of evening reading on a lit screen instead of paper cuts melatonin by about half and pushes your body clock back roughly an hour and a half 5. The radio sitting next to your head is a bystander.
The fix is displacement over shielding. The antenna worry is empty; the phone still has to leave.
If you feel EMF-sensitive: the headaches and sleepless nights are real, but in blinded tests people can't pick the active field from sham, and symptoms appear just as often when it's off 7. It's a nocebo โ real symptoms, wrong cause. Relief runs through the expectation, not more shielding.
The fine print โ when to skip it, and what people get wrong
