The material in Breaking the Waves: A Primer on Sensitivity to Electromagnetic Frequencies is a subset of the more comprehensive work Riding the Waves: Diagnosing, Treating, and Living with EMF Sensitivity. However, it does include updated information. For those who have already purchased the book, you have the information you need to implement numerous remedies that are effective in reducing and/or eliminating the symptoms of sensitivity to problematic electromagnetic frequencies.
I am continually working to better understand sensitivity to EMFs and searching for new and better ways of diminishing andor eliminating the symptoms associated with it. I will be posting entries that deal with the updated material as appropriate.
If you wish to have a more thorough understanding of sensitivity to electromagnetic frequencies, I suggest you read Riding the Waves: Diagnosing, Treating, and Living with EMF Sensitivity.
