Bluetooth What You Will Learn Nowhere Else – Is It Really Dangerous?

Posted by Lloyd Burrell on August 24, 2010 under Bluetooth radiation | 98 Comments to Read

A few days ago I received this message from one of my readers, Craig, who is worried about Bluetooth radiation:

Hi Lloyd,
I have a quick question, or maybe not such a quick question.
What’s the best way to reduce radiation when listening to streaming audio on a cell phone:
– A  Bluetooth headset?
– Does Bluetooth drastically cut down on radiation as compared to having the cell phone near my ear?
– A physical wired headphone?
– Does the radiation transmit up the headphone cable that’s physically plugged into the phone?
– Those “thick protector stickers” that you apply to the outside of your cell phone?
Unfortunately, I depend on the internet, and consequently cell phone, for the majority of my news; and tune into my favourite radio stations while driving for work, at the gym, or doing chores around the house.
Do you have a chart or is there an article you can direct me to that contrasts/compares methods of getting the most sound to your ears with the least amount of radiation?
Thanks for a great site and newsletters!
Craig

Here is the answer I sent him :

Hi Craig

Thanks for your great question. Below is my not so quick answer :

Bluetooth Radiation – What You Need To Understand

Bluetooth is the name of a wireless technology that uses pulsed radio frequency signals. Anybody that has been following my website will have just felt their ears prick up as I said the word “pulsed”. Not good.

Here is what Dr. Andrew Goldsworthy has to say about pulsed radiation:

“Pulses carried by microwaves are particularly dangerous. This is because their very short wavelength allows the transmission of pulses with extremely rapid rise and fall times, and it is the rate of change of the fields (rather than their total energy) that does most of the biological damage” Source.

Because when we talk about pulsed radio frequency signals we are of course talking about radiation, or in this case Bluetooth radiation. Read on….

Bluetooth is now used extensively in today’s world, in cell phone headsets, computer accessories such as keyboards, printers, personal digital assistants (PDAs), personal media players, GPS, gaming equipement, and also various medical health and wellness devices.

This Bluetooth technology is used for more and more personal and commercial applications. The Bluetooth Special Interest Group now lists over 6000 products that utilize Bluetooth technology.

All the more reason that we should be really clear as to what the potential dangers are with Bluetooth radiation.

Is All Bluetooth The Same?

No.

Bluetooth transmits at frequency levels in the 2.4 GHz band.bluetooth radiation 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 less 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 manufacturers specification. I say ‘should’ because it seems some manufacturers deem in unnecessary to share this information. That’s why I’ve done some research on this and listed at the bottom of the page a selection of the ‘lower EMF’ Bluetooth devices that are on the market.

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 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 science on this issue can seem confusing. The problem is there is a huge amount of funding bias and outright manipulation of the science in order to publish studies which show favorable 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.

So to answer your questions Craig:

Does Bluetooth drastically cut down on radiation as compared to having the cell phone near my ear?

Yes, Bluetooth does drastically cut down radiation exposure compared to having the cell phone next to your ear, if you could be sure that you were only exposing yourself to Bluetooth radiation. The problem is that when you use a Bluetooth headset that the transmission strength from the cell phone itself is not decreased. If for instance you are putting the phone in your pocket or clipping it to your belt then you are at the same time exposing your internal organs to radiation.

The Swiss Federal Office of public health recommends that cell phones should not be carried in a front trouser pocket when making calls and that it may be safest to hold the phone away from the body to reduce radiation. Studies (Whittow 2008) have also found that metallic objects situated near your waistline, such as coins, a belt buckle, rings, keys etc increased the Specific Absorption Rate (SAR) in the body at different frequencies.

Specific Absorption Rate (SAR) is the rate at which your body absorbs cell phone radiation. Bluetooth devices do not require measuring and reporting of the SAR (Specific Absorbtion Rates) values.  So we’re kept completely in the dark as to possible radiation absorption levels.

Does the radiation transmit up the headphone cable that’s physically plugged into the phone?

Yes, it can. The headphone can act as a sort of antenna for your cell phone giving the radiation a fast route into your brain. The science is sketchy on this but in my view, having tried wired headphones, they are not the solution to reducing your radiation exposure. This is now widely accepted and yet wired headphones continue to be sold by the boatload to the population at large.

To overcome the antenna effect of wired headphones use an airtube hands-free kit.

Do you have a chart or is there an article you can direct me to that contrasts/compares methods of getting the most sound to your ears with the least amount of radiation?

I don’t know of any comparative resource on this topic but to answer your question, “what’s the best way to reduce radiation when listening to streaming audio on a cell phone?”. Remember: distance is your friend.

In other words, avoid holding your cell phone next to your ear at all costs. If you do need to hold a cell phone next to your ear a Pong case can reduce your exposure.

Do cell chips offer protection from cell phone radiation?

I’ve tried cell phone chips, diodes and neutralizers from many different suppliers. None of the devices I’ve tried worked. In some cases using these devices can be more dangerous than not using them.

Low EMF Bluetooth Headsets

Despite reading all of the above if you’re still committed to using a Bluetooth headset where does this leave you?

To determine how dangerous a Bluetooth device is, the best information we have to go on is the power classification, or the Class.

The worst offenders are Class 1 headsets. There are quite a few of these on the market, for instance the Callpod Dragon is a Class 1 Bluetooth headset and therefore to be avoided if radiation exposures are your main concern.

In an ideal world you’d use a Class 3 headset, which are the lowest powered headsets and therefore the safest. Unfortunately because most people’s top priority is having a good strong signal Class 3 headsets are a relic of the past. That leaves us with the Class 2s.

The problem is the power classification of a headset takes some rooting out. The manufacturers are very ‘low profile’ about sharing this information.  I’ve tried contacting a few of them – most of them don’t reply and the one’s that do often don’t know what I’m talking about.

Nevertheless I’ve rooted some out. Click here to see my listing of Class 2 Bluetooth headsets.

Conclusion –  Are Bluetooth Head Sets Dangerous?

The frequency of Bluetooth wireless headsets is the same as that of microwave ovens. Microwave ovens use much higher power levels. But the power levels themselves are not the issue. Its the rate of change of the EMFs, the pulsing, that causes most of the biological damage. Bluetooth radiation is dangerous.

Bluetooth headsets are particularly dangerous because they are held within centimeters of the brain and they are used in conjunction with a cell phone. So you’re getting double exposure. If you use Bluetooth in a car the effects are multiplied due to the Faraday cage effect.

So Craig, the bottom line is avoid Bluetooth headsets. Avoid Bluetooth radiation and practice safe cell phone use.

Bluetooth is only the tip of the EMF iceberg. There’s too much to go into here.

I’ve written an EMF Protection Free Report which is over 20 pages long which explains how these different EMFs affect our health and what you can do to protect yourself. Sign up here.

    Thanks for that detailed reply and for posting so fast!

    However, while I was looking up those airtube headsets, I couldn’t help but notice that almost everyone I saw only had a tube length of about 6-12 inches. If I understand you right, the radiation still goes to the end of the wire and the metal housing/coupling before the tube starts. Users would still be placing this ‘Live” wire next to their body … not the safe 3 feet away. Are their tube headsets with longer tube lengths.

  • Lloyd said,

    Hi Craig
    It all depends what sort of protection you are looking for and to what extent you are using your cell phone. For me personally the airtube does not provide sufficient distance between head and my cell phone. Initially it would not bother me, if I started using it regularly I would start to feel unwell. You might not feel unwell, but just because you can’t feel any discomfort does not mean that it is not harming you. However for most people, using an airtube type device is a definite improvement on using bluetooth or a wired connection.

  • Lisa McCollum said,

    I just found your site Nd have been reading. A month or so ago we had wireless Internet installed at our home that required a somewhat large antennae to. E installed on our roof. We live in a very rural part of east Texas and this is basically our only solution for fast Internet. Since installation my cell phones have been getting extremely hot, when I hold it for a long period of time I start to feel as if my insides are burning, same for my iPad. Our dog is jumpy and shakes his head and scratches his nose constantly as if something is in his ears. I feel terrible. Am I going crazy or could this antennae which is pointed at a tV news tower because that is where their transmitter is,, be causing all this?

  • Lloyd said,

    No you are not going crazy; you are showing signs of electrical sensitivity. Your reaction could be caused by the antenna itself or it could be caused by the associated WiFi. Trying switching your new installation off for 3 or 4 days and see if there is any improvement in your symptoms. Once you have identified the problem you will probably then need to deal with your sensitivity, which is not so easy but is possible, I can help you if you need it.

  • Reeq said,

    Hi Lloyd,
    Thanks for all ur info, so helpful. I need some pointers i recently purchased an ipad 3 as i need to get out of my flat more (its full of other peoples wirless singlas and baby and we hate being in her brain fog) i am on a sim deal so i dont use the wireless on the ipad as i have seen it sends out huge pulses /spikes on emf readers on u tube uploads..firstly would u say that a sim is safer ? It uses the cellular connection..
    i am looking for solutions as im sensitive to emf now get dizzy etc and tingling hands. I keep it as far as possible from me when i use it as i use it to browse so am connected wen using, (apparantly the ipad wen not connected omits very little emf, so low it can be sat on ur lap independant tests showed but its so bad when connected to wireless!)

    I have purchased ‘pong radiation reduction cover fhe ipad’ seems pretty good to me, i picked up a stylus rubber tipped pen, and i use a keyboard. I need advice here, am i better to use a wired keyboard or bluetooth? of course bluetooth would be easier but emf wise for sucha thing what do u think? I was thinking of either getting a folding one or silicone that rolls up for ease of transport.

    I am also considering a grounding mat of some sort… and a screen protector too that reduces rdaiation i am sure they exist somewhere as sometimes we have no choice but to use the screen in a hurry …

    its crazy how much effort and cost we have to go to reduce all these problems why cant everything be made of wood lol with electronics inside !

  • Lloyd said,

    Hi
    Using a SIM card means you will be exposed to radio frequency radiation and using the touch screen will probably mean you are being exposed to a mixture of magnetic and electric fields (the independent tests are not very relevant to someone who has symptoms of electrical sensitivity). Given your symptoms the ipad is not the ideal computer set-up. Ways to reduce your exposure might be to use an external wired keyboard and/or mouse and an extension on your SIM card, see http://www.electricsense.com/1138/my-9-tips-to-cut-down-on-exposure-to-computer-radiation/ I would not advise grounding around electrical equipment, see http://www.electricsense.com/1861/using-earthing-to-combat-electromagnetic-pollution-my-review/

  • Susan said,

    Dear Lloyd

    I am thinking of buying a new car, and most of them have bluetooth. What is your opinion of this?

    Thanks.

  • Lloyd said,

    Hi Susan
    Bluetooth installations in cars mean that you are being exposed to pulsed radio frequency radiation. Given everything that we know about RF radiation this is to be avoided it is possible to get your Bluetooth disarmed, see http://www.electricsense.com/252/radiation-in-cars-practical-tips-on-how-to-minimize-it/

  • Reeq said,

    Hi admin, thanks for the reply…:-)
    Well I just purchased the PONG Ipad cover case, pls see this link- http://www.pongdev.com/landing/new-ipad.html 45 pounds, as it seems a great product i hope im not wrong but this is the only case out there that iimproves signal and reduces radiation both 3g and wireless by 80 percent or just a little above that, also improves download speed too, how it works is it uses its own inetrnal antenna pls have a look and tell me what u think it arrived today and i must say it seems the real deal and i managed to catch a couple of reviews on it that seemed good.

    I have the choice to use either wirelss or 3g via the sim, dissapointed to learn il still get radiation via 3g actually,
    QUESTION.1: can u pls tell me which is worse? The wirless or 3g? I hear that wirelss on the ipad 3 is a pulsating one that can hit very high frequeuncies (spikes) :(… few people on u tube hav tested it and showed the crazy readings..

    I aslo hear that it is better to run it via its battery not plugged it for emf reasons. I am using a keyboard unfortunatly cant use a mouse because the ipad does not allow any mouse function on it… so i use a stylus pen instead with a rubber tip… gives me a bit more distance. I keep the ipad around 60 cms away from my body to keep as much distance as possible.
    QUESTION 2: Do u think this distance is safe enough? and do u think the stylus pen will reduce the contact ?

    Apparanty wen its not connected to the net the emf levels r v good v low, so thats good to know. But unfortunatley wen running via battery the led backlit screen is pulsating (not visible to the eye) and this is triggering my migraines and many other peoples some people had to return it, im stuck trapped in a contract monthly now ! Alo teh v high resolution has made me dizzy and feel a little vertigo symtoms… again people have reported this

    QUESTION 3: is there such a thing as a screen cover to help reduce this and radiation??
    QUESTION 4? this may sound really dumb but does wood help reduce the emf and radiation so say i had a wood stylus pen i wonder?

    Thanks for the links u sent me i must study them further.. :-)

  • Lloyd said,

    Hi
    I am familiar with the Pong cases, the technology is reliable, they do what they say they do.
    Question 1: If you use your 3G on a 6 foot extension cable in an area where cumulative RF levels are low this would seem a better solution, but without taking readings with an RF meter it’s impossible to say categorically whether the wireless in your flat or using 3G in an open space is better or worse.
    Question2: Any distance between you and an EMF source is better than no distance, so using a rubber (non conductive) tipped pen is a good move. Again whats “safe” or not is impossible to say without taking readings with an EMF meter, having said that if you are electrically sensitive and using it generates no symptoms this is a good indication.
    Question 3: Yes radiation shields do exist. I have used them but if you are electrically sensitive I am not convinced its money well spent, there is not a significant reduction in exposures…
    Question 4: The rubber tip is an insulator on your pen so it will offer some protection.

  • Auser said,

    Thanks for the detailed info, mr Lloyd.

    What`s your opinion about products such as the “Wireless Air-tube – Anti-Radiation Bluetooth headset” see headsetairtube.com

    It`s like a combo of bluetooth and airtube. So what`s the point, just to gain 15 cm away from the brain?

    I`m in a debate, thinking to buy Motorola S9-HD / S10-HD for comfort reasons (I like the arch they have), I hate messy cords. Does the fact that the S10 has a better range and `call steadiness`, mean that it emits more radiation ?

    Thanks again

  • Lloyd said,

    I’m only going on the description on the website you referenced, but a “wireless air tube” is one step forward two steps back. Airtube technology can reduce your EMF exposure but Bluetooth adds to it….
    As for your question on the cell phones, its not because a cell phone has better range that it emits more radiation, it might be working more efficiently and therefore emit less radiation. See my cell phone tips for my advice on reducing your exposure: http://www.electricsense.com/775/how-to-protect-yourself-from-cell-phone-radiation/

  • Auser said,

    The Motorola S9-HD / S10-HD are bluetooth headsets, so is Nokia BH-505, I`m in a debate which one to buy.
    People say S10 has the best range and most consistent signal, does that mean it is a “stronger transmitter”?
    It is “2.1 with embedded A2DP AVRCP profiles for stereo music streaming” while S9 is 2.0.

    On one hand there`s comfort, I want to use it wires free. On the other – I don`t want my brain to be radiated. Is it really that bad (bluetooth radiation)? I`m not extre sensitive to EMF but I can say that if a person isn`t sensitive, it means he doesn`t want to feel, it doesn`t mean he`s not affected.
    I suppose the air tubes might be fragile, especially when I stick it in my pocket.

  • Auser said,

    One more thing. I think about the bluetooth air tubes vs. non bluetooth air tubes.
    When someone calls my cell phone while at home, if I use the BT air tubes, I can get farther from the cell phone itself than if I used it with wired air tubes.
    So what`s worse, have the phone 0.7 meter (about 2 feet) away from you and the air tube`s metal wire (passing radiation) 15 cm from your brain; OR ; Have the phone 10 feet away and a bluetooth on your chest ?

  • Lloyd said,

    You can determine if one Bluetooth headset emits more than another by looking at what class transmitter is indicated on the packaging. Class 1 transmitters emit the most radiation and class 3 the least. If one headset has a better range and more consistent signal than another, but is of the same class, this does not necessarily mean that it emits more radiation. It may be that the technology is better and that it emits less radiation. « So what`s worse, have the phone 0.7 meter (about 2 feet) away from you and the air tube`s metal wire (passing radiation) 15 cm from your brain; OR ; Have the phone 10 feet away and a bluetooth on your chest ? » I know of no research on this question.
    « Not being able to feel » does not equate with « not being affected », correct. Airtubes are more fragile than their wired counterparts or the Bluetooth version but if you are concerned about your exposure its a no brainer…

  • AC said,

    Hi Lloyd,
    What do you think about Bluetooth keyboards designed for tablets or other screens? I can’t imagine the signals would be very strong when the keyboard is meant to be used right next to the screen; maybe class 3? Also any local radiation would probably be focused only near the hands and not pose much risk for the rest of the body. Thanks for your input!

  • Lloyd said,

    Hi AC
    I have’nt tested a Bluetooth keyboard or tablet though I don’t doubt that the EMFs are not very strong but studies (see Bioinitiative report and many others) show that cumulative exposure to even weak EMFs can have significant adverse effects. For long term use its better to use wired versions.

  • Patty V said,

    Hello,

    I appreciate the posts about bluetooth tech. I am wondering if a Wireless Bluetooth Handset would be the best option: http://www.herringtoncatalog.com/es669.html
    Though it would be limited to home use, it would be good for those of us who are home a lot. Do you think this would be the best option (better than the airtube set?

    Thank you,
    Patty V.

  • Lloyd said,

    Hi Patty
    I’d avoid anything wireless, its emitting RF radiation. The studies tell us what this does to us long term…even if you can’t feel it the damage is still being done. Buy yourself a regular corded phone…much safer.

  • asbestos perth said,

    Hi

    Just wondering if its better to share an internet connectio via bluetooth sharing vs wifi sharing. I know both have cons but what is the less harmful form of radiation? thanks

  • Lloyd said,

    In terms of radiation levels WiFi and Bluetooth are very similar. Bluetooth has a maximum power output of 100mW and most WiFi devices are also operating at 100mW – some are operating at 200mW. So in some instances Bluetooth may be safer.

  • Rick said,

    Lloyd,

    I have a friend who has felt effects of using Pen Tablets such as the Wacom Bamboo. She describes the feeling as tingling, and reports that the same tingling can be felt even a day later. She uses this type of device on a daily basis for work as a designer.. Is there any way you can think of to minimize these effects?

    Rick

  • Lloyd said,

    Hi Rick
    I have never used or tested a pen tablet but I can see how they work. EMFs are involved, electrical and magnetic fields for sure and possibly some RF radiation also – I’m not sure if the pen is wireless (connected by radio waves) with the tablet. In any case, the problems the same. Exposure to EMFs. The first step is EMF avoidance and protection. So it may (will probably) mean that she needs to stop using this device and go back to what she was using before. I would encourage her to read up on this, my free EMF protection report is a good introduction.

  • FredW said,

    I would like to use Bluetooth to listen to music from my cellphone or computer if only I could make sure that the earphones would only be receiving and not transmitting, because I assume that if it is only receiving transmissions the earphones themselves would not be causing me harm. (Of course, the phone or computer that is 10 feet away would be transmitting, but perhaps that would not be causing much harm.) Do you know if there are some earphones that do not transmit, if there is a way to turn off transmission, or any other way to eliminate or cut down on their transmitting property?

    Thanks for all your work on radiation.

  • tom moore said,

    this is really interesting
    did you know you can get cancer from bluetooth

  • Lloyd said,

    Not just cancer, but a long list of auto-immune diseases and neurological disorders….

  • Lloyd said,

    Hi Fred
    For your Bluetooth earphones to work they create a connection with whatever phone or computer is emitting the signal. This connection is known as “syncing”. It creates an invisible link between the two devices. Which means that with Bluetooth there is always a signal being emitted by your earphones. But there are now Bluetooth earphones on the market which emit less radiation sold by Amazon.com.

  • FredW said,

    Thanks, Lloyd, for the information. Do you know if the “syncing” signal keeps repeating? In other words, is it transmitting a lot or a little? I know that many people think that “any” would be too much, but I’m really trying to evaluate this and make up my own mind if it represents a real danger. I know some people are more sensitive to emf than others. I don’t think I’ve noticed bad effects from having wi-fi and a cordless phone around (although we DID just send back a DECT cordless phone after reading about the high amount of emf it gives out), and having a bluetooth “receiver”, even if it sends out some signals, sounds like it may be at the low end of the “danger” scale.

  • Lloyd said,

    Bluetooth earphones emit radiation – that’s for sure. We also know its low level radiation. But more and more studies are linking low level radiation with health concerns – you may not feel any symptoms now that doesn’t mean your body is unaffected…

  • Adrian said,

    Thanks so much for that clarification. One would think that bluetooth, being state of the art wireless would be safe but no, these evil companies continue to contribute to destroy health through technological convenience. A real insidious design and intent. I will continue to use wired products as best as I can.

  • FredW said,

    “Bluetooth earphones emit radiation – that’s for sure.”

    But, how often and how much? Compared to having a wi-fi router somewhere in the house, for example, or using an older model cordless phone? I’m trying to compare it to other devices that I and others commonly use. I’m trying to compare and evaluate.

    Thanks

  • Lloyd said,

    The easiest way of comparing is with the SAR, look in the fine print of your user manual for your headset to see what this is. According to Cindy Sage, co author of the BioInitiative Report Bluetooth headsets typically radiate at 0.23 watts per kilogram (W/Kg). You can compare this with the SAR of your cell phone. Studies have shown adverse biological effects at 100 times lower levels.

  • FredW said,

    Thank you, Lloyd. I don’t presently own one and may not get one, but your info gives me something to look for and understand. One part I still don’t quite get: does a SAR number like that represents an average over time or only when the headset would be transmitting, which possibly might not be for very much of the time. A cellphone, for example, might typically be broadcasting for 50% if the time in use. But one could imagine that the headset is only broadcasting infrequently, to “check in” or whatever it does to maintain contact with the transmitter.

  • Lloyd said,

    Hi Fred
    SAR is not an average over time. According to the FCC “The SAR values recorded on the FCC’s authorization and in the cell phone manual to demonstrate compliance with Commission rules indicate only the highest single measurement taken for each frequency range that the particular model uses.” All you can do is be aware of these EMF dangers and avoid unnecessary exposures- for me Bluetooth is an unnecessary additional exposure.

  • FredW said,

    Thanks, Lloyd. I’ve learned a lot from your site and these exchanges, and, so far, I haven’t bought a bluetooth headset.

  • Paul said,

    Hi, I have been doing a lot of trail running and tend to do aboput 10 miles per run. I have been using my iPhone with a tracking app whilst streaming music to an earpiece to avoid wires annoying me. I was attaching the phone to my arm in a waterproof housing but I have noticed my right shoulder has become very painful and I cannot even do any push ups with it any more (Used to easily do 60 without pause.)The last 2 runs that I have done I moved the phone to a waist belt and streamed it from there. I ran for 1 1/2 hours and I now have a pain at the site of the telephone. I am really worried about this but I still want to record my runs. Should I just use wired headphones and switch blue tooth off or do I need to stop using the GPS too?

    Thanks

  • Lloyd said,

    We shouldn’t be affected by GPSs….they are only a receiver (as opposed to a cell phone which is an emitter/receiver) but when I was at my most electrically sensitive a few years back I was reacting to my GPS (in the car). Wired headphones is the safest alternative. I would also look towards reducing your EMF exposures in your life generally – my free report can help you with this.

  • Paul said,

    Will do and thank you.

  • Hamada said,

    Lloyd,

    Thanks for very informative article on bluetooth. My son has been asking me to get him a bluetooth headset for his PS3 game, and after reading this I am not sure what to get. He wants it because he can talk to his friends while playing, currently he is tying up the home phone by keeping in it on during his game to communicate with his friends while playing with them. Any ideas? Thanks in advance.

    Hamada

  • Lloyd said,

    Hi Hamanda
    More and more of these devices have bluetooth only connectivity….if you can get him a wired headset it will be safer for him.

  • jak plihal said,

    Lloyd, thanks for this great dialog. I am not feeling effects, but wanting to get ahead of the curve. In reading all of this — and being someone who walks around my office when I talk – I am inclined to:

    *A) put my mobile phone on the tower side of my office on a window sill — get an airtube bluetooth headset that is a well designed level2 or 3

    B) Remove my cordless phone system

    C) Remove my wifi system — work with phone wiring through out the home for Internet connectivity

    D) suspend my plan to get an IPAD or maybe get a samsung with pen instead and use wired connect with a keyboard.

    D) Use my grounding matt — or get feet on dirt daily when away from technology

    E) Figure out SAR rating for the external monitor HighRes 24-27″ external monitor I am going to purchase — and consider getting an EMF screen.

    F) figure out how to block EMFs from neibhors in our bedrooms… any ideas?

    Thanks for fielding all of this — give links to products you support wherever aprorate please! –Jak

    thanks alot for your very useful article.

  • jackie said,

    hi lloyd,
    i didn’t read through all the questions and comments, so please forgive me if someone already asked this. i just got a new car, which is equipped with bluetooth, so if i sync my cell phone with it, the sound just comes through the car speakers. i’m wondering if that is harmful, because if it is, i probably won’t use it. thanks!!!

  • Lloyd said,

    Using your cell phone in your vehicle is not advisable… cell phones work harder in cars to maintain the communication with the cell tower and there is a Faraday Cage effect which means the radiation is concentrated…like in a microwave oven. Adding Bluetooth into the mix adds to the problem by adding another layer of RF radiation.

  • Bora said,

    Lloyd,
    The Faraday cage effect has two conditions for shielding EM waves: The holes in the cage must be much smaller than the wave length of the wave and the conductor has to be thick enough so that radiation does not escape or penetrate. The radiation cellular communications use is in the SHF (super high frequency) range so it has a wavelength of about a centimeter which is significantly smaller than the non conductive regions (“holes”) of the vehicle so the cage effect will be unable to concentrate radiation. Bluetooth on the other hand has a wavelength of about 10cm so the conditions still are not satisfied.

    Hi LLoyd

    I have been trying to find out without success from Sony as to what class of bluetooth is used in a playstation 3 – my son wants it to play skylanders. The intention is to use wired controls and switch bluetooth off but this isn’t possible – I can get wired controls but the bluetooth is part of the circuit board so I can’t take it out or disable. I am assuming it will be C3 OR C2. These appear low relative to some devices people have in their home – I don’t want my son to miss out if this is a small amount of radiation in the scheme of things – it all gets very confusing when you don’t inderstand some of the measurements. eg 100 w = how many v//m
    1. Whats your view
    2. Do you know anything about the PS3 – someone told me the wireless can be turned off but I am struggling to get a straight answer from Sony
    3. I read some of your saftey tips on cars and you mentioned remote locking – we all use remote controls for our TV’S is this different
    4 My son uses skylanders on DS – wireless disabled – the figures load by infrared onto a portal – it takes only a second and then the figure is on for good – I wasn’t worried about this as its not using wireless but with your comments on cars it made me wonder if this was a problem – it is something he doesn’t do very often I would add and with all the games I mentioned we do restrict use.

    I would welcome your views/knowledge – the problem is that if you have none of these gadgets at home kids friends encourage them to go to their house to play with them and then they are exposed to more stuff such as wireless and DECT phones – its a real dilema

  • Lloyd Burrell said,

    Unfortunately I can’t answer all your questions because I’ve not tested the wireless version of the PS3….we bought the PS3 with wired consoles for my son….this emits no traceable levels of RF radiation. Wireless games units for children are not safe and should be banned – my opinion is based on extensive research and my own personal experience with EMFs.
    The Playstation 3 also emits high levels of dirty electricity – see the video on my Youtube channel.
    For an understanding of the measurement units see: http://www.electricsense.com/3772/how-to-understand-the-different-measurement-units-that-are-used-to-measure-emfs/

  • Wida said,

    Hi Lloyd

    I want to know which one is better, headphone or earphone? I mean the one which have lesser radiation… thanks…

  • Wida said,

    Lloyd…

    adding to my question before.. now I know that “it is air tube which makes the radiation lower…” but I only found air tube in earphone… is there any product which has air tube integrated in headphone?

  • Lloyd Burrell said,

    Yes air tube technology is the safest….I’m not aware of any air tube headphones on the market. Before buying an air tube headset read my review http://www.electricsense.com/4859/cell-phone-radiation-protection-do-air-tube-headsets-work/

  • Justin Fredrick said,

    Lloyd,

    My dog barks at very loud levels next to the microwave. Is it possible the microwave is causing my dog to do this? He doesn’t bark nearly as loud when he’s away from it.

    Worried,
    Justin

  • Lloyd Burrell said,

    Animals are way more in tune to nature than us humans and they are more in tune to when nature is being polluted by EMFs than we are….which is why its a good idea to observe them. The effects of EMFs have been shown to affect the behavior of cows and horses.

  • Lucas said,

    Great article. My question is what is your view on the Parrot Zik wireless Bluetooth headphones? I’ve seen more and more people utilizing these new headsets and I have always felt that they are not safe. I own one myself but I feel a bit uncomfortable using them for a prolonged listening (they sound great).

  • Lloyd Burrell said,

    They look great but from a health perspective they are not so great……they rely on Bluetooth technology….pulsed digital radiation is transmitted a few centimeters from your brain….

  • jackie said,

    lloyd,

    how about PEMF (pulsed electromagnetic frequency) devices used for healing? i know that many holistic practitioners use these for cancer patients and other patients with chronic illnesses. how is this different than the pulsed technology of bluetooth?

    thanks!!

  • Lloyd Burrell said,

    Bluetooth, cell phones, cell towers, wifi…its about 24/7 exposure to pulsed digital radio frequency radiation which we know has adverse biological effects….PEMF is about controlled exposures under the guidance of a qualified health care practitioner of different forms of EMFs (not necessarily RF) with the specific goal of inducing healing…

  • jackie said,

    thank you!!! :-)

  • Jason said,

    I came across this website because I am thinking of getting a Jawbone Up wristband. It’s a Bluetooth bracelet that tracks your activity and syncs with your phone. Would this be okay to use, or should I be concerned? You wear it 24/7

  • Lloyd Burrell said,

    You should know that in wearing such a device you are exposing yourself to pulsed digital radiation (and all that implies) 24/7….I don’t advise it.

  • Jessica said,

    Great article. I have actually been using a wired in ear headset for a couple of years. I recently read how dangerous wired headsets are unless they are used in conjunction with a ferrite bead. Can you help with a couple of questions:

    1. Are wired headsets really dangerous?
    2. Are “on the ear” headsets safer than “in the ear” for emf protection?
    3. Would I need a ferrite bead for the “on the ear” headset?
    4. Do ferrite beads really help, if so, how much radiation is eliminated by a ferrite bead?
    5. How often should you replace the ferrite bead?

    Thank you.

  • Lloyd Burrell said,

    Wired headsets can be dangerous…they can act as an antenna transmitting into your brain ambient radiation in your environment…the more EMFs in your environment the higher the risks. Ferrite beads are said to reduce intermediary frequencies and radio frequency noise that may be picked up by wiring but I haven’t read any studies on this specifically…..the safest form of headset on the market currently is the airtube.

  • Daryoush said,

    It’s been a month that I want to talk about a matter to someone but I was deeply afraid of making a fool of myself. For about two years I’ve been using a Bluetooth headset, couple of hours daily and for the last month as I put it on my head I start to feel… strange (hard to explain). I just feel something’s not right in my head, nerves or… I really do not know how to explain it. I’m not even sure if this feeling has something to do with bluetooth or It’s just fake. Based on my logic this radiation can’t be that effective and that’s the reason i keep using it to fight with this thought but the effects are getting worse and worse and that’s why i finally googled it and found this article.
    As I have tons of other health issues never decided to visit a doctor for this one.
    Now please tell me if what i said is not logical at all, helps me stop pining.

    P.s. I apologize for my poor English.

  • Lloyd Burrell said,

    Your reaction…..that in someway there is something wrong with you……is understandable….this is the world we live in…..most people are unable to feel Bluetooth radiation and similar low power forms of EMFs….but many people can feel these things…..and its quite normal to feel them…. on this website lots of people recount similar experiences and whats more the science shows that these technologies are potentially very dangerous.

  • Roland said,

    Hello. I’m buying a new toyota with a bluetooth key. Would that be dangerous to my health?
    Thank you.

  • Roland said,

    By the way, they call it electronic ignition key, so i don’t know if it’s bluetooth..

  • Lloyd Burrell said,

    These devices usually emit RF radiation…like cell phones and Bluetooth but often at a lower frequency….is it safe? Exposures tend to be minimal….thats to say very low power and for a very short time….I can only answer in a general sense because these devices vary from car to car…….the only way to be sure what your exposures are is to measure with an RF meter.

  • Phil said,

    I had bought a lg bluetooth hg730 in late December. I kept it in my left ear at all times while working because it played music as well as allowing me to be able to answer my calls. After wearing this in my left ear for a few months while at work the music went staticky and I had a sharp shock in my ear. Instantly my body felt weak, I thought I was going to faint. I started vomiting. I was rush my the ambulance to the er. Several ct scans and MRIs it was shown that I had a large lesion on my brain. Now I have to have physical and speech therapy.

  • Jack said,

    Hi Lloyd. I hope you’re doing well.

    I have a question about the Playstation 3 console. Earlier in this page you responded you got a wired version of the PS3 for your son. I wasn’t aware there was such a thing. Do you have any idea what it is called?

    I have heard one person say that if you plug the official sony PS3 controller into the system to charge, it turns off the wireless signal on there. If there is any way you might be able to check, could you?

    I understand this request sort of makes you go out of your way, so no worries if you can’t or don’t care to.

    My son wants a Playstation 3 and I am very concerned about this, but if the signal turns off when it’s plugged in, or there are good wired in options that’d be great. I sincerely appreciate the effort if you are able to help.

  • Lloyd Burrell said,

    Jack,
    With my son’s Playstation, with either the wired game controllers plugged in or not plugged in it makes no difference, there are no RF radiation emissions from the PS3 unit. His is just a regular PS3 there are no markings on it…..but his unit is a few years old….technology changes….the only way you can be sure that what your son is using does not emit RF radiation is to take readings with an RF meter.

  • Cathleen said,

    Hi – Thank you so much for your great report. I have a question about something called a bio mat. It’s an amethyst-filled mat that I sleep on that delivers infra-red heat.

    New-age-y, all well and good . . . except it is heated up by electricity. You plug in the control panel to determine what level of heat your want.

    Given that it requires electric energy to work, do you think this device is safe to sleep on?

    Thanks,
    Cathleen

  • Lloyd Burrell said,

    Cathleen,
    I would not be inclined to sleep on anything that is plugged into the electricity while I am sleeping…..testing with an EMF meter will allow you to determine your level of exposure.

  • Jackie said,

    Cathleen, There’s a Ben Greenfield podcast about EMFs in the Biomat. He has one and has gotten great benefits from it, but he’s also concerned about EMFs in general. You might want to listen to it:

  • Nolipop said,

    Hi Lloyd!
    What about bluetooth devices like Sony’s smartwatch?
    I understand that bluetooth radiation( especially headsets) harm your brain, but what about devices you wear on your wrist, like smartwatches? Is it dangerous? Should I stop wearing it? It’s on my wrist for 10+ hours a day. Smartwatches work with your smartphone( Bluetooth turned on). I always make sure to leave my phone in the drawer or in a case, so I don’t really have any contact with it.
    Well, hope to get an answer- that sh*t scares me! *laughs*

  • Lloyd Burrell said,

    If its a Bluetooth device then you’re exposing yourself to pulsed digital microwave radiation…..the studies indicate the adverse health effects are not confined to the brain they are very widespread.

  • John Allen said,

    HI Lloyd,

    Thanks for the informative article. What is your take on bluetooth neck loops that are used in conjunction with hearing aids? I use mine to stream music from my iPOD Nano to my hearing aids, not so much for cell phone use (i.e. no transmitting to phone)

    Thanks

  • Lloyd Burrell said,

    You may not be using Bluetooth in conjunction with a cell phone but you are still exposing yourself to pulsed digital microwave radiation….a wired headset is a safer alternative.

  • Sensei said,

    I would like to know three different ways that one can use in protecting himself against cellphone radiation. I read the book: Disconnect by Devra Davies and some of the information it contains is contrary to some of the answers provided about bluetooth radiation.

  • Lloyd Burrell said,

    For my cell phone radiation protection tips, see http://www.electricsense.com/775/how-to-protect-yourself-from-cell-phone-radiation/

  • Sensei said,

    is it true that it is safer for one to carry his cellphone in his pocket with the back turned to face out because the antennae are built such that they are at the back and in-built?

  • Lloyd Burrell said,

    Cell phones vary in their design……its impossible to say with any degree of certainty if this would reduce your exposure. Keep your cell phone in airplane mode if you carry it in your pocket.

  • Sambi said,

    Hey Lloyd,

    are there any bluetooth alternative technologies for wireless experience, that are less harmful? This is someone who wants to use’em mostly for iPod music (headphones).

    If not, then what are some safer practices you’d recommend for that?

    Thanks in advance,

    Sambi

    (P.S. just subbed to your newsletter)

  • Lloyd Burrell said,

    Sambi,
    The safest alternative to Bluetooth is wired….better still is to use airtube technology, see http://www.electricsense.com/4859/cell-phone-radiation-protection-do-air-tube-headsets-work/

  • Cat McGuire said,

    I bought the air tube headset Lloyd recommends. It has good sound quality, but here’s the drawbacks

    * Wires always getting caught/pulled (goes with the territory)
    * No pause button — terrible omission. No volume control either.
    * Poor phone calls — I can hear perfectly fine, but everyone tells me (unlike my bluetooth headset) that my voice is muffled. I quit using it to talk to people by phone
    * durability? – I heard they are more fragile and the tubes get clogged. Just got it so don’t know about that yet.

    but obviously, the bottom line is that my brain is not getting radiated by a bluetooth or wired headset. Got to keep it in the context.

    Maybe one day if there are enough of us, they enhance the design to make air tubes as functional and robust as wireless headsets.

  • Rick Upshaw said,

    Lloyd,

    My work is on the internet. I am constantly using Google Maps in my car. I live in an apartment where there are more than 30 identifiable signals from people’s wireless networks as well as wireless cell phone systems.

    Since I most certainly don’t want any kind of technology in my ears after reading this post and all of the comments, I was actually considering buying one of the Parrot bluetooth systems that mutes my radio speakers whenever a call comes in, or whenever the navigation system wants to give me directions. However, now that I’ve read this post, apparently that option is a no-no as well. Not having my cell phone while in the car driving isn’t an option. So what’s the safest alternative for having my cell phone and using it while in the car? Is there some kind of protection I need to build into my car?

    I’ve read all of the comments above. Are you a proponent for somehow “unplugging” all together, or do you have some kind of safer alternatives for some of the technologies discussed in your post?

  • Lloyd Burrell said,

    Rick,
    For using your cell phone in the car the safest alternative is to have a car phone kit installed with external antenna……an old style Motorola achieves this…..there may be other makes of phone that can do the same thing but it needs to have the antenna positioned outside the vehicle.

  • Leo Lambert said,

    Just want to add for those asking about the Playstation 3, when the USB cable i connected between the console and controller Bluetooth switches off, when you unplug the USB cable and turn the console on Bluetooth is enabled.

    The playstation 4 is always wireless, even with the USB cable is plugged in.

  • Benn said,

    Oops.. Hello Lloyd, I am starting a new job on Monday and they want me to wear a bluetooth walkie talkie set up. Now my question is: In your opinion does the radiation only happen when I am talking and or listening to someone? Or is it radiating my brain even if I’m not talking to anyone whilst wearing it around all day long?? I can’t find any info about this online. Thank you in advance.

    Benn.

  • curious said,

    I am interested in this device to monitor my sleep.

    https://www.kickstarter.com/projects/hello/sense-know-more-sleep-better

    However it operates with wifi and bluetooth and ANT.

    Is this worse than putting a cell phone in airplane mode and running a sleep app?

  • Fred said,

    Hello.

    I have used a wireless headset (Logitech G930) for about 3 years on average maybe 3 hours each day. The headset has a usb transmitter that works at a 2.4 GHz frequency. If I now stop using it all together…
    Do you think the potentially negative effects would reverse or become unimportant in the nearest future?

  • Jen C said,

    Hi Lloyd…thank you so much for your information!
    I have suffered for years with health issues that couldn’t be diagnosed.
    I worked in Call Centres for 10 years, then became self-employed, using a cell phone almost exclusively for the last 13 years.
    I am now realizing that the most debilitating of my health issues began and have compounded since beginning work with headsets, and heavy wiring in the buildings.
    I have been diagnosed with Stage 4 Rosacea, including Ocular Rosacea, which I unknowingly had 13 years ago.
    The reason I looked this up today is that after my symptoms had been improving significantly over the last 2 months, yesterday I had a long conversation on my land line at home, using a VTech Bluetooth Headset. During the approximately 90-minute chat, the area around the corner of my mouth began to hurt and swell…and when I hung up and checked the mirror, my eye on the same side was cloudy and red, and the area around the corner of my mouth was visibly swollen and red…and hugely painful. It was worse this morning.
    It took me til this morning to think to look up Bluetooth.
    This is my Rosacea at its finest…is my Bluetooth likely to blame?
    I can’t find rating info on my VTech Headset.
    I use built-in Bluetooth in my vehicle and my cell phone speaker at the office….this is the fastest I have experienced an adverse reaction.
    Thank you so much for any answer you can provide!
    I have signed up for your newsletter as well.

  • Lloyd Burrell said,

    Hi Jen
    There is a potential for harm with Bluetooth FACT. It’s not for me to diagnose…..what I can say is trust your gut on this….I’ve laid out lots of information on this site for you to ACT & take charge of your own health.

  • Nicky curnow said,

    Hi Lloyd,

    My son has a PS3 which is connected via an ethernet cable (we don’t have wireless) but the controller is wireless and has has a lead to charge it. Do you know if you keep the charger lead connected to the controller does it stops the wifi

    thanks

  • Defiant said,

    Let me guess…smoke signals are dangerous too…because of carcinogens? And speaking face-to-face is dangerous…due to airborne pathogens?

  • Mary said,

    Hi Lloyd,

    Thanks for the great info, I’ve realized now that after 3 years of trying to figure out why I’m struggling with lethargy and weakness at least some of it is probably related to my heavy use of Bluetooth headsets–I’ve used them over 4 hours a day on average for studying, listening to music, and attending remote meetings. I’m willing to cut them out completely at this point. They both pulse very slightly, still remaining below .1 on the scale. Why does the wired set pulse just like the pulsing Bluetooth? And then I see you mention an airtube Bluetooth version on Amazon… how safe are these? I have a TriField Meter and both my Bluetooths (one is 5 years old, one is 2 years old) as well as my standard wired music earbuds register so low that I find it hard to believe they are very harmful; does the airtube version really cut out 98% compared to typical Bluetooth or is their claim relating to the difference between the headset v. phone to the head? Thanks so much for your time on this!
