My wife is very sensitive to using computers. She had hyperthyroidism 20 years ago and has become very sensitive, her throat / thyroid area and chest hurt after using her Mac laptop. We thought it was the WIFI, so we switched to ethernet, that didn’t work. Then we attached the laptop to a projector and used long USB cables so she could be 6-8 feet away from the laptop, but the pain still occurs after continued use (½ hour or more). We measured the EMFs from the computer, laptop and mouse and it’s negligible except if the meter is right next to it or touching the ethernet cable.

Can anyone explain why this happens? Does anyone have suggestions on how to eliminate the problem? I read somewhere that the optical mouse might still be causing the problem, if so has anyone tried switching to a trackball style mouse?

Thanks in advance for any comments!

Hello mattb and welcome to the forum. Here are a few suggestions, based on my experiences. I expect you have tried most of them……
Scour the main site here (and others) – there my be some suggestions you have not tried.
Try an external (USB) keyboard – I think you must have done this to get 6-8 feet away from the laptop. Or voice recognition software (often available as part of the system). But I’ve measured high electric fields from keyboards (external and built-in).
Try covering the mouse with aluminium foil as a temporary measure. Ideally this should be grounded, but that might be tricky to do.
Try screening the main body of the laptop with foil. I’ve measured appreciable microwave (RF) fields from the processor/hard drive area, and I screen my laptop because of this.
A trackball mouse may still contain some electronics, so it could be problematic. Probably worth trying at some point.
My partner had a problem with a mouse. She now uses the tracker pad and seems to be better. This does not make sense to my logical brain, because the hand is nearer to the internal electronics, but if it works…….
Try grounding the computer. Surest way to do this is to plug in a USB cable and attach the other end to an electrical ground – using wire, crocodile clips, ingenuity etc. If you are lucky there might be some exposed metal on the laptop which you could attach to instead of the USB cable. This made a big difference for me when I did it.
Try grounding your wife. In theory and practice this can increase body voltage, which lots of experts tell you is not a good thing. However, in real life I do this and it helps a lot, even when my body voltage increases slightly. As always, take care – if she feels worse then stop doing it. Body voltage can be tested with a basic multi-meter.
Anecdotally, Apple computers sometimes seem to be more problematic than others, for some as yet unidentified reason. Has she tried a different type of computer? Old ones tend to be better.
Does she spend time in the area where she works on the computer, but with the computer switched off? There could be some other (external) source of radiation (including geopoathic stress) affecting that part of the house. Again, appropriate meters would identify any EMFs.
None of this should be construed as medical advice.
These things have helped me. This does not mean that they will necessarily help anyone else.

PS – I assume you have removed all internal sources of radiation – eg no wifi, no cordless phones etc. Make sure wifi is disabled on the computer (many people miss this) otherwise the computer will broadcast its presence quite frequently with a strong signal. Again an RF meter would pick this up.
