With regards to cell phone usage I've limited mine to speaker phone and also switch it to flight mode at night before I go to bed. As for WiFi I only turn the radio on when I need to access via my iPhone. My desktop and Xbox uses ethernet only.
Why do you jump through these ridiculous hoops if you don't even know if wifi emissions are dangerous or not? Lemme ask you this, do you smoke? Drink alcohol? Eat fried, cured or smoked meat? All of these things are guaranteed to be far, far more dangerous to your health than the ludicrously low energies from the radios of these things.
Btw, do you live in a house that uses high-tech gadgetry that contains all kinds of chemicals with VERY WELL DOCUMENTED negative health effects? Do you use any common household chemicals such as antiperspirants/eau de cologne, shampoos or shower creams, air fresheners, fabric softeners, spray-on cleaning agents, and so on? Many of these products contain chemicals that also are documented as strongly allergenic or even carcinogenic.
What gives people cancer from cell phones (assuming that's ever happened) is almost certainly NOT the EM emissions from the phone's antennas, but rather the chemical fumes emitted from the product itself while you hold it up to your face so you can breathe 'em right in. There's often stuff like flame retardants, plasticisizers, flux residue, solvents from epoxy resins and so on in electronic products that evaporate over time, particulary when it heats up during use.
I don't think there's been enough research into these technologies to put my health on the line.
You're sure to get far more dangerous crap in your body from gassing up your car than from sleeping with your cellphone in your pants pocket across the room...
Hell, what about taking a walk in downtown NY or LA... Shit, the air in any big city's liable to cut years from your life expectancy and you worry about wifi waves?
Ludicrous!
If you feel comfortable hedging your bet knowing that if later research shows that it causes health effects then that's your choice, but don't say you haven't been warned.
Again, that's a ludicrous standpoint when there's no even indirect methods described where these apparatuses could affect biological matter.
The physics that we use to design these things in the first place simply doesn't support the notion. Alright?
BTW what are you going to do if more research points to irreversible health risks?
Run around and PANICPANICPANICPANIC!!!
...Err, no.
Driving your car to the supermarket instead of walking there, and taking the elevator/escalator instead of the stairs are going to have more serious health repercussions than being in the same room as a wifi/cellular transciever.
