HHS-OASH-2026-0397-5907 https://www.regulations.gov/comment/HHS-OASH-2026-0397-5907 THE PROBLEM and CAUSES In 2020 and without prior symptoms, I experienced heart arrhythmia and heart palpitations when exposed to radio frequencies (RF) from WiFi and Bluetooth when using a smart phone. The symptoms have continued from 2020 through October 2026, and in close proximity to the smart phone of one foot distance or less, and the symptoms are most severe when holding the smart phone. I feel a tingling in my hands and arms. The symptoms are noticed when using only WiFi, or only Bluetooth, or both. The Cellular RF produces less effect. Since 2020, I no longer use WiFi and Bluetooth on my smart phone, except when syncing devices and moving away from the devices during the sync process. Other devices also cause heart arrhythmia and heart palpitations when exposed to RF from WiFi and Bluetooth. This includes a smart watch when using Cellular, WiFi and/or Bluetooth. I use the smart watch for the purpose of monitoring health data including during exercise. This type of data can be collected by the smart watch with all RF disabled, including Cellular, WiFi and Bluetooth. Enabling any one of the RF signals immediately causes heart arrhythmia and heart palpitations. I only use the smart watch with RF disabled. There are many cordless devices powered by a rechargeable battery that also cause heart arrhythmia and heart palpitations. Of the devices I recall using since 2020, the following list includes the devices that cause heart arrhythmia and heart palpitations when exposed to EMF from rechargeable batteries, and RF from WiFi and Bluetooth. They include: ⁃ Smart Phone - caused by WiFi and/or Bluetooth ⁃ Smart Watch - caused by WiFi and/or Bluetooth ⁃ Smart Pad - caused by WiFi and/or Bluetooth ⁃ Smart Pencil - caused by Bluetooth ⁃ Laptop - caused by EMF and WiFi and/or Bluetooth ⁃ Wireless Keyboard - caused by Bluetooth ⁃ Wireless Mouse - caused by Bluetooth ⁃ Indoor Cycling Trainer - caused by WiFi and/or Bluetooth ⁃ Health Devices - caused by EMF from devices and rechargeable battery ⁃ Percussion Massager - caused by EMF from rechargeable battery ⁃ Cordless Vacuum Cleaner - caused by EMF from rechargeable battery ⁃ Cordless Outdoor Equipment - caused by EMF from rechargeable battery ⁃ Cordless Tools - caused by EMF from rechargeable battery ⁃ Buildings - caused by excessive WiFi signal and/or close-proximity to Bluetooth Note that I can use conventional corded devices such as a corded vacuum cleaner without detrimental effects. What is it about rechargeable battery technology that causes such severe sensitivity? MITIGATING ACTIONS The following mitigating actions have been mostly successful at resolving heart arrhythmia and heart palpitations when exposed to EMF from rechargeable batteries, and RF from WiFi and Bluetooth. ⁃ Avoidance #1 - focus is on avoiding WiFi, Bluetooth and EMF by disabling RF and avoiding the use of rechargeable battery-operated devices, tools and equipment ⁃ Avoidance #2 - focus is on avoiding WiFi by hardwiring WiFi to devices via an Ethernet cable. Unfortunately, Bluetooth cannot be hardwired, it would be very helpful if it could be hardwired. THE FUTURE The book The Invisible Rainbow: A History of Electricity and Life, by Arthur Firstenberg documents a 185+ year history of severe detrimental effects caused by EMF and RF, and the data presented in the book shows the detrimental effects to be the most severe during the rollout of new electrical and RF technologies. This is no longer a hidden problem. There are technologies such as BioGeometry that have been proven to address the detrimental effects of EMF and RF at the source. It is time to put this and other technologies into full-scale testing and use to eliminate the detrimental effects of EMF and RF in the design phase of all hardware and software. It only takes leadership that is willing to take the lead and do it. Thank you to RFK Jr for taking the lead.
