Bluetooth is the name of a wireless technology that uses pulsed radio frequency signals.
How Do Bluetooth Headsets Work?
Bluetooth Headsets and Technologies emit wireless microwave radiation. Microwave frequencies have a short wavelength and a rapid rate of oscillation. This is what enables them to travel long distances carrying information without needing to be contained in a wire.Bluetooth Wireless Radiation vs Cell Phone Radiation
Bluetooth Technology uses the same microwave radiation to transmit data as cell phones do to receive calls. The only difference is the range. A cell phone antenna picks up signals from cell phone towers and satellites, while a Bluetooth headset/technologies are receiving radiations from a few feet away.Bluetooth Radiation is more dangerous than Cell Phone Radiation?
Yes!Your radiation exposure with a Bluetooth headset is the sum of cell phone radiation (turned on your belt or in your pocket) plus the Bluetooth radiation. So Bluetooth radiation in itself may be less dangerous than cell phone radiation but when you use a Bluetooth earpiece you are always exposing yourself to both Bluetooth radiation and cell phone radiation, a double whammy! Bluetooth radiation is particularly dangerous in so far as earpieces and headphones go because of the proximity to the head of these devices.
Is all Bluetooth the same?
No!Bluetooth transmits at frequency levels in the 2.4 GHz band. There are three power classes and it’s these power classes which are your best indicator as to what level of Bluetooth radiation you’re exposing yourself to
Class 1 transmitters — are the most powerful, have a range of 100 meters and peak transmission power of 100 mW (milliwatt)
Class 2 transmitters — are usually found in mobile devices and they have a range of 10 meters and operate at 2.5 mW peak transmission power
Class 3 transmitters — these are the weakest and operate in a range of fewer than 10 meters and have a peak transmission power of 1 mW
So the first thing to do is to check what class of transmitter your Bluetooth headphone is. You should find this information in the manufacturer's specification.
What about Bluetooth radiation?
The radiation from your Bluetooth earpiece will zap you just the same because Class 1 Bluetooth headsets can expose you to the similar radiation levels to your cell phone if they’re operated in close proximity to the body.What does Bluetooth Version mean?
Don’t confuse Bluetooth version and Bluetooth Class.When looking at Bluetooth devices you’ll often see terms like “Bluetooth V2.1 compliant” or “Bluetooth version 3.0”. This tells you the Bluetooth software the device uses but a Bluetooth version has nothing to do with Bluetooth class.
Bluetooth versions are all about offering enhanced data speeds. These data speeds are improving all the time as the technology evolves. Bluetooth version 1.0, the earliest Bluetooth version, offers a data transmission rate of 721 kbit/s. Version 3.0 HS offers a transmission rate of 24 Mbit/s. There’s no correlation between Bluetooth version and Class.
Is a Bluetooth version with a lower transmission rate safer? It’s possible but we don’t know. There are no studies on this so we’re pretty much in the dark.
What does Science say about Bluetooth Radiation?
The problem is there is a huge amount of funding bias and outright manipulation of the science in order to publish studies which show favourable results. The cellphone industry is ready to spend a considerable amount of money to protect its interests. Various studies support (American Cancer Society 2008, Martinez & Burdalow 2009) the view that Bluetooth headsets when used in conjunction with cellphones, decrease the overall levels of SAR exposure to the head. Whereas other studies show a diversity of hazards from these exposures.One study found that “men who keep cell phones in a trouser pocket in the talk mode while using a Bluetooth device may experience decreased fertility“. High-frequency electromagnetic fields can lead to a significant increase in blood pressure and affect biological processes in the body just the same as cell phones. Just two hours of exposure to high-frequency EMFs from a cell phone or Bluetooth headset can cause irreparable DNA damage.
Health issues caused by Bluetooth devices
Communicating using Bluetooth devices is preferred over cell phone devices, Bluetooth devices are not entirely safe. Long-term exposure to microwave signals from Bluetooth devices can cause so many health hazards. I have discussed some potential hazards below.Ear Pai
Ear pain is one of the health hazards caused by prolonged use of Bluetooth headsets. Bluetooth headsets clipped into ear's outer portion cause pain due to their weight. The uncomfortable sit of Bluetooth headsets can also cause ear pain. You can use cushions and weightless Bluetooth headsets to avoid discomfort.Hearing Loss
It is another side effect of Bluetooth headsets. Headset volume can be tuned to higher levels but you should know that sounds louder than 85dB can cause hearing loss. To protect your hearing ability, keep the volume low.Weight Gain
Electromagnetic frequencies and radiations interrupt the natural energy flow of the body. According to the King Institute, repeated exposure to this type of radiation can also cause weight gain.Brain Cancer
When we use Bluetooth headsets, we are bringing these devices close to head. Individuals who use this device continually get affected by its radiations even when the device is not in use. Even small doses of such radiations affect brain cells and can cause brain cancer.Leukemia
It is another hazard of using Bluetooth technology. Radiations coming from Bluetooth devices are not as strong as microwave radiations but their continued exposure can result in Leukemia, low immunity system and diseases.Distracted Driving
A big factor in this statistic is talking on the phone while driving. Although using a Bluetooth headset allows you to keep both hands on the wheel, a study by Carnegie Mellon revealed that just talking on a cell phone reduces brain activity associated with driving by 37 percent.Other side effects
Bluetooth radiations may affect individuals differently but problems arise basically because microwave radiations interrupt cell functioning and natural transmission of energy. Some other side effects associated with microwave radiations are birth defects, miscarriage, hair loss, Alzheimer disease, neck pain, and headache.Conclusion:
Bluetooth headsets are particularly dangerous because they are held within centimetres of the brain and they are used in conjunction with a cell phone.So, the bottom line is avoided Bluetooth headsets. Avoid Bluetooth radiation and practice safe cell phone use.
