HHS-OASH-2026-0397-2375 https://www.regulations.gov/comment/HHS-OASH-2026-0397-2375 Dear Secretary Kennedy, My name is Dr. Michael Halliday. After 45 years in chiropractic practice, I recently retired from clinical work, but not from what has been a major focus of my life: developing natural approaches and technologies intended to protect and improve human health. I have followed your decision to examine the potential health effects of electromagnetic fields with great interest. For more than 20 years, I have been working on this very problem — but particularly on the part of the discussion that I believe receives too little attention: What can we actually do about it? My work began with water and frequency-based technologies and later developed into mineral-based materials designed to mitigate the biological effects associated with EMF, Wi-Fi and, more recently, 5G exposure. Rather than attempting to block electromagnetic signals, our approach is designed to modify their interaction with the biological environment. We have developed applications for plastics, paints, textiles, mobile phones and other products, and have conducted blood-based testing that I would be pleased to share with your scientific team. I have also spent years investigating what I describe as “electrosmog,” including the possibility that electromagnetic environments may influence water and, consequently, biological systems. I am not writing simply to identify another potential problem. I am writing because I believe we have practical solutions worth investigating. The technology exists. We have developed it, tested it, and can demonstrate it. I would greatly appreciate the opportunity for a brief conversation with you or the appropriate members of your HHS team. Rather than trying to explain decades of work in a letter, I would prefer to present the technology, the observations behind it, the testing performed to date, and allow your experts to evaluate it independently. Additional information about our work is available at protxs.com. Thank you for your work on this important subject. I would welcome the opportunity to contribute. Respectfully yours, in health, Dr. Michael Halliday -- Dr. Michael Halliday Founder 616-881-6453 drmike@protxs.com
