A few things about EMF sensitivity:

Take down all wifi systems in your home, use a direct cable to a router like in the old days. Keep your phone in a faraday cage pouch, which can easily be built with aluminum screening (even when it is off, as they still do stuff when off these days).

Metal, naturally acts as a antenna. EMF clouds up around metal, and will cause all kinds of health problems. Get the metal out of your head: metal root canals, metal caps, metal bridges, at least. The metal fillings may not be worth the bother once those others are out.

Also, filter your water. You may be unaware of how much iron is in your water. Again, more metal introduced into your physiology every day will act as an antenna.

Next, you can turn your bedroom into a faraday cage effectively with aluminum screening. It's cheap, and ugly, but it actually works. You may want to shield the wall where your electric meter is, too. Ten feet in every direction should be sufficient to attenuate the effects.

Next, if you are having respiratory issue you can take querciten which is a natural anti-inflammatory which works surprisingly well on upper restpiratory issues related to EMF.

Finally, there are scalar wave devices which can create a bubble which help to negate the effects of EMF on the human physiology. There is a lot of anectdotal, as well as scientific evidence that these are very effective, but they can get expensive. Blushield is one, but there are smaller companies out there that may be cheaper and still do the same thing.
