evidence: If fact, there is now a large body of research that indicates a wide range of effects on humans from exposure to ELF, VLF, and RF fields. A study I ran across just a few weeks ago found a correlation between exposure to microwave frequency EMFs and neuropsychiatric effects such as depression (ScienceDirect Article). [...] It seems that as emf increases, our need for adaptogens (and or cannaboids) may likewise become evident. Does anyone have actual data on how earth shelters block or mitigate emf?
