​​​​Biological Impacts

of Bluetooth™ Devices


     An extension to the wireless convenience of cell phones, cordless phones and Wi-Fi connected devices are some very short range devices such as Bluetooth enabled wireless keyboards, mice and printers that integrate with Wi Fi enabled  computers or

tablets, or with cell phones within our personal or working space.  Of some concern as far as proximal bodily exposure is concerned are Bluetooth enabled watches,

headphones and other wearable devices.  A comparison test of the EMF from Bluetooth Headsets with that from a cell phone shows that headphones radiate far less than a cell phone.  But are even these relatively feeble readings safe for prolonged, hour-after-hour use so close to the head?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

     Bluetooth, as well as WiFi, DECT Cordless Phones, Video Baby Monitors and Microwave Ovens ALL use the 83 MHz-wide 2.4 GHz Industrial, Scientific, and Medical (ISM) band.  Because Bluetooth devices are not full featured computers their bandwidth can be much narrower than that of WiFi routers and the range of their transceivers need be only sufficient to communicate with your nearby tablet, computer or phone, (up to 30 feet away).  Bluetooth uses Frequency Hopping Spread Spectrum (FHSS) and hops between 79 different 1 MHz-wide channels in this band. [209] 

     There have been far fewer studies of Bluetooth radiation than of cell phone radiation. The dearth of formal studies allows marketers to claim that Bluetooth radiation is safe. Not on research proving Bluetooth to be safe, but only on the lack of any research proving it to be unsafe.  This sort of hollow safety claim is often used to by companies who manufacture new technologies for the retail market. [210]

     Bluetooth Headset use has been linked to blindness, deafness, brain tumors, neck pain/stiffness, skin rashes and headaches. [210a]   


     Increased Wi-Fi use is contributing to ADHD and coronary problems. [194] 

Dr. Sinatra mentions "numerous, potent mitochondrial toxins in our environment today – mercury, insecticides, pesticides, chemicals such as phthalates, pharmaceutical medications and electromagnetic & RF/wireless pollution itself.  He describes RF radiation as the “newest” mitochondrial toxin."  [194a]  The American Academy of Environmental Medicine (AAEM) "strongly supports the use of wired Internet connections, and encourages avoidance of radiofrequency such as from WiFi, cellular and mobile phones and towers, and “smart meters.” " and "With WiFi in public facilities as well as schools, children would be exposed to WiFi for unprecedented periods of time, for their entire childhood. Some of these signals will be much more powerful than would be received at home, due to the need for the signals to go through thick walls and to serve many computers Page 2 Wireless Radiofrequency Radiation in Schools simultaneously. Signals in institutions are dozens of times more powerful than café and restaurant systems."  [194b]  


Another recent article articulated on possible negative consequences of Wi-Fi and RF exposure on children including cancer risks, behavioral changes, cardiovascular irregularities and sleep disorders. [201]  In April, 2016, "...an Israeli TV documentary titled “How We are Killing Ourselves—Wireless Radiation” won a high rating and Haifi ordered Wi-Fi removed from all schools." [202]  See this recent compilation of actions by governments at all levels setting policies and recommendations regarding the use of Wi-Fi and cell phones. [203]
