The Frequency Wars have already begun, even before 5G. It's progressed well into areas of suppressed science at this point. Shielding largely doesn't work anymore unless you can create a total faraday cage, and that's not practical for a home, even with shielding paint like YShield. In addition, scalar waves can pass through almost anything.
To be completely honest, I carry a frequency broadcasting brief case that also projects scalar waves. I also surely have them in my home. Doing it correctly and in a way that can be accurately tested and scientifically proved is not cheap. The good part about scalar waves is while their range and penetration is substantial, local scalar waves tend to override more distance scalar waves. The body/cells do reach entrainment to frequencies, that much has been studied, so while they can broadcast frequencies to disrupt mitochondrial function, it is possible to broadcast frequencies that are more localized that enhance mitochondrial function. (as one example)
Entrainment frequencies are coming through virtually anything that can carry a current these days. The general, and most common entrainment frequencies are measurable, and quantifiable for those that care to investigate. They generally resonate with Fear/Despondancy/Loathing/Apathy. I don't think most people can grasp, or even want to grasp the full scale of the war against humanity with these control and soft-kill technologies.
Eat a good diet. Keep hydrated with purified then re-mineralized water. Take good supplements. Reduce body cortisol levels. Consume AMPK activator substances. Raise your pre-pulse-inhibitor by consuming Emodin/Emodin containing food/spices. Then you are more resilient to such things. Sadly, most people, at least in America, are going to be victims due to ignorance and/or lack of discernment.
