"There are NO safe levels of exposure to electromagnetic fields above the frequency of 15 Hz due to their negative effect upon the neurological system. Dozens of peer reviewed research studies (see frequency specific animal studies) showed animals exposed chronically to frequencies above 15 Hz resulted in detrimental behavioral changes and above 20 Hz stress hormone production. Once nearing power frequency transmission at 50/60 Hz the mitochondria become severely debilitated and cancer likely results over time. Watch this video start to finish and you’ll recognize just how bad the threat of radiofrequency (RF) is to your health." - https://earthpulse.net/sleep-emf-rf/earthpulse.net/sleep-emf-rf/
