Reports incapacitating head and facial tension during heating-system installation, attributed to workers’…

I wish to add this to my earlier Comment - Tracking Number : mv0-p58t-iti1 As a person affected by Radiofrequency (RF) Radiation, and Wireless Radiation Exposure I am submitting this comment in response to HHS’s Request for Information on Electromagnetic Fields (EMFs), Radiofrequency (RF) Radiation, and Wireless Radiation Exposure. In 2026 we had a new heating system installed in our (rented) home. The system was chosen by our landlord and so we had no choice concerning the system chosen. The installation crew were in the house for four days, during which I experienced increasing tension in my face and head, becaming even more severe (incapacitating) on the fourth day when the new heating system was activated for the first time. I believe that the first three days discomfort was caused by the close proximity of the several mobile phones (and other devices?) being used in the house by the installation crew. I believe that the incapacitating tension that I experienced on the fourth day was caused by the radio frequencies emitted by the wireless thermostat/control apparatus communicating with the heating apparatus itself. After the installers left the house we disactivated the heater and removed the battery from the thermostat/control apparatus. Several hours later the discomfort ceased.
