Premise: Neurologists found that GHz wireless RF had modest but quite negative effects on people's brains. Subtle collective effects in neuronal firing patterns across the brain due to interactions with the EM fields within the skull lead to enhanced feelings of angst and frustration with the world causing them to lash out on the internet using their... GHz wireless RF devices.
The angst-enhancing effects were slow to decay, and so the cumulative exposure over any 24 hour period was the metric for evaluating reduction of exposure.
The effect saturated at fairly low fields, so the exposure to a device a few meters away or a cell tower or router even farther was equally as bad as holding a device close to the head.
In order to quickly help people reduce their exposure to the signals, governments and Stack Exchange users struggled to develop a scheme that would allow people to continue using their devices while significantly lowering their exposure. Tin foil hats were proposed, and DIY stores quickly ran out of rolls of metal window screen as people were "wallpapering" their homes and designating unused spaces as "RF rooms".
Question: What were the more clever and effective ways proposed over the following weeks to allow people to get wireless signals in and out of and between their current devices without getting much into their heads? Those using household and readily available materials are of particular interest.
