Do you use a wearable like a FitBit or Jawbone? How about a bluetooth headset? A bluetooth enabled appliance? A car that has bluetooth technology? Some other bluetooth-enabled self quantification device?

Then this episode is for you, because it's important to know exactly how bluetooth technology is affecting your sleep, your circadian rhythms, your health, your gut barrier, your blood-brain barrier and your performance.

In Part 1 of this episode, I talk to Christian Johan Smith, who is founder at Phone Halo, which creates technology that helps you track devices that you might lose. In this discussion Christian and I talk frankly about what he knows as the CEO of a company that relies on Bluetooth technology, and what I know from my research in the health space.

Resources Christian and I discuss during Part 1 of this episode:

Trackr app for iOs/iPhone

Trackr bluetooth tracking apps on Amazon

The research study that Ben cites relating bluetooth to the blood-brain barrier

Articles and studies on health effects of EMF

Bluetooth airtube headset

The anti-radiation Pong case for iPhone

In Part 2, I talk with Dr. Jack Kruse, a respected neurosurgeon and CEO of Optimized Life, a health and wellness company dedicated to helping patients avoid the healthcare burdens we typically encounter as we age. He is currently in private practice in the Gulf South and his research has been published in respected dental and medical journals. Jack's previous episodes at BenGreenfieldFitness.com include “Jack Kruse Tells You How To Live Like A Polar Bear And Eat Like A Great White Shark“, “How You Can Use Cold Thermogenesis To Perform Like Lance Armstrong And Michael Phelps”, and his “How To Beat Jet Lag Naturally“.

Questions, comments or feedback about whether bluetooth radiation is dangerous? Leave your thoughts for me, Christian or Jack below!

Update: after recording this two-part series, I contacted Timex about the MoveX20 activity and sleep that I've used. They were very helpful, and informed me that it is a “Class 3” bluetooth device (listen to the podcast to see what that means), that it has a power of 1mW (0 dBm) and that it transmits every 1 second. I'd encourage you to do the same research for any devices that you wear!

    Frankly speaking, the given information is useful. I had gone through the review an I found it is similar to on the information given on the Facebook and other technical sites.

  2. Madeline says:

    Hi Ben!

    I am considering purchasing a Fitbit Blaze just to track my fitness routine, get my HR, calorie count, etc. It doesn’t sound like it’s great to wear all day with the EMF. Do you have an alternative idea or one that you wear? Thanks!

      1. Rob Pandolfo says:

        While waiting for my Oura to ship I got restless and ordered a whoop. I was concerned about the lack of knowing of the BT sensors were on or off so I asked the support team if they would stop pinging the phone when the phone is in Airplane mode overnight and they said the whoop will always be scanning.

        This was the response:
        Aug 7, 13:27 ADT

        Hi Rob,

        Sorry for the confusion. Unfortunately, there isn’t a way to turn BT off on the Strap so it will continuously try to connect to the phone. Please let me know if you have any further questions.
        Rob Pandolfo
        Aug 7, 13:18 ADT

        Thanks for the reply. My concern is not on the phone end more the strap. How do I know the BT is off and not still scanning when the BT on the phone is off. Will it only be active when the phone trys to ping the strap? Or is it always on and scanning for the phone when the phone is accessible.

        Probably a nerdy question but need to know for myself as well as EMF sensitive clients and accuracy of hrv monitoring.

  3. Please study up on frequency/wavelength etc.
    A mhz frequency is NOT a shorter frequency than a a ghz frequency. (at 20:52)
    This podcast if rife with errors like this.

    Where can I listen to Part 2?

    1. Lee says:

      I also was confused about this at first, as the browser’s built-in libsyn player seems to fill up at the end of part 1, but if you allow it to continue playing it will run for another 45 minutes for the Dr. Jack Kruse interview. Or just click the download button to download the full MP3.

  5. senshi says:

    Are there ways to measure the impact on the cellular membrane that Dr. Jack Kruse is mentioning? Something that you could ask at a medical examination and compare to a healthy baseline? Also, it would be interesting to know if such effects, once noticed, can be reversed if exposure to EMF is interrupted.

  6. Daniele Poggio says:

    Hi Ben, terrific article as usual. I have a couple of specific questions (hence my first time commenting here !):

    – Apple Airpods: are these a definite No? I am using them and find them quite practical !

    – Spire breathing tracking app: would you recommend disabling bluetooth and only sync the app every now and then? But then it defies the purpose of many of the features… Let me know.

    1. I do recommend disabling Bluetooth and Wi-Fi whenever it is not needed. Everything else you need to know is here: https://bengreenfieldfitness.com/2016/12/how-to-d…

  7. Maritza says:

    When at home or work is it better to be connected to your service provider vs the WIFI? I’m assuming if you try to download something through the service provider you will get more radiation. I would love to hear a podcast with resources.

    Thx

    1. Six of one, half a dozen of the other. Best to be hardwired in.

  8. Maritza says:

    Hi Ben,

    Do you happen to have a list of alternative products you recommend as alternatives for wifi? I would like to know how to go about rewiring my connection. I’m not sure if removing the wifi router and connecting my computer directly to the cable provider’s modem be the solution. Does TRIONZ create negative ions in the body to fight back on all the radiation we are regularly exposed to. I”m assuming every time I use google maps on my phone and it uses the GPS to figure out where I am it is creating a lot more radiation. I had a Pong case with my iPhone 6 but can’t find one for iPhone 7. Is there anything else you suggest to cut back on the radiation on the phone? Listing to my iPhone using Bose SoundSport in-ear headphones, does it cause more radiation to be transmitted to me? What are alternatives? Some of the links in this site are no longer working.

    1. There are a ton of questions here. Most of this I cover in my How To Biohack A Healthy Home book: https://greenfieldfitnesssystems.com/product/how-…

      And also here: https://bengreenfieldfitness.com/2016/12/how-to-d…

      For more, I'd be happy to help you via a personal one-on-one consult. Just go to https://bengreenfieldfitness.com/coaching. and then choose a 20 or 60 minute consult, whichever you'd prefer. I can schedule ASAP after you get that.

  9. Gerard says:

    Hi Ben,

    Maybe you answered this in the podcast, if so sorry for asking. Anyhow, in your opinion is it safe to wear a blue tooth polar h chest strap overnight while sleeping? i like to check my HRV first thing in the morning. Thanks

    1. Nope. I only wear in the morning for 5 min when I measure.

      1. Nita says:

        I use a Polar V800 watch (Bluetooth for transmitting heart rate with a strap) while mountainbiking and other endurance activities. I am thinking of going to their next generation of watches which is the Vantage V which utilizes photoplethysmography (PPG) to measure heart rate (Ocular Heart Rate via the skin) . I did call Polar with the question is Bluetooth always on, its the same as always, their watches only use Bluetooth to pair to a transmitter or phone or if you want to use the app to transfer info. It would be a good discussion to have over which technology is safer.

  10. Gawain says:

    Hi Ben, I’ve just been given a Fitbit Surge that measures HR using the green LEDs to measure changes in blood volume. As light frequencies are essentially ‘EMF’ and have biological effects on us, do you know whether this could cause a problem even if I have bluetooth turned off? I’m wondering if green is close enough to blue on the spectrum to potentially cause issues after sunset – even if it’s on the skin and not on the eyes?

    1. This would NOT be a damaging frequency. Not powerful enough. Only potentially issue would be SLIGHT disruption in melatonin production if used at night.

  11. Tim Brady says:

    Hi, my question is this: If I never use the Bluetooth headset, am I still being exposed to microwave radiation in a car equipped with Bluetooth technology? (I don’t own a cell phone and would never use a Bluetooth headset but it’s becoming almost impossible to find a car that isn’t Bluetooth-equipped.)

    1. You should be fine unless the bluetooth is turned on. You can just leave it turned off.

    2. Mary says:

      Every time I wear my blue tooth my heart starts feeling funny I been doing a test with it I will wear it for about a hour around my neck and I won’t wear it again for a week and no more pains and then I tried it again and my heart started hurting again I’m done with it because it scared me

  12. Paul says:

    any wireless radiation is causing cancer and lot more …. this radiation has been classified carcinogen class II by the WHO where every country voted – it is the same class as tobacco asbestos and other – all these dangers are banned as cancer causing … so you draw your line

  13. Richard L says:

    My first concern is that Jack compared the speed of radio waves to the speed of light, this is 100% false, radio waves travel at the speed of sound, and they react closer to the way sounds act then light. Sound and radio waves travel 1,129 feet per second compared to light at 186,282 miles in that same second.

    These waves in no way fact the same as microwaves, just the fact that Jack insists that radio works at the speed of light makes me question everything else he says.

    For an example on how slow take travel, let’s go back to the days of telephone transmissions through radio enabled satellites, where it would take a few seconds for your words to reach the listener on the other side of the planet. They would then respond, giving you a dead period of 5 to 10 seconds, If indeed radio traveled at the speed of light, it would be like talking to someone in the same room.

    !

    1. Howard Pimental says:

      https://physics.stackexchange.com/questions/68728… Highlight

      21 Jun 2013 … No. Radio waves ARE light, and so they travel at the speed of light. Possible exception: The speed of light c that is always talked about as the “speed limit of the Universe” is the speed of light in vacuum. Light travels slower in a medium, and how much slower can be dependent on the wavelength of the light …

  14. Josh says:

    Ben, you stated that you do not use Wi-fi in your home, in looking at getting rid of Wifi I wondered about powerline networking, Internet over power – have you looked into the safety of powerline networking as an alternative to running ethernet all over the house?

    1. First, be sure to read my book on How To Biohack The Ultimate Healthy Home (if you haven't yet) https://greenfieldfitnesssystems.com/product/how-…. Next, I briefly looked into powerline networking and it looks like a low EMF alternative, but it is NOT available at all in my area and is often very expensive. But it is a potentially viable alternative….

  15. EmtiazAlom says:

    This post was not only helpful with the comment issue, but had also great links to other entertaining blogs. Some of them I will most likely keep visiting! Thanks.

  16. markberman123 says:

    Hi Everybody,

    I use a radiation free Bluetooth headset, great gadget that has blocking card for the radiation.
    I got headaches from my previous Bluetooth headset,
    but now I use one from smartandsafe and It actually helps me.

    I recommend them very much!

    Mark

  17. The dangers of Bluetooth radiation is widely overlooked so good to see you raising awareness on this issue Ben. I wrote a detailed article on this subject, see http://www.electricsense.com/1791/bluetooth-radia…

  18. tdolanguage says:

    thanks ben! I'm excited to try the wristband when it's available!

  19. tdolanguage says:

    I listened to this podcast a week or two ago, and have thought about it a lot throughout my daily activities. I work at a university, and the entire pace is full of high powered wifi signals (they just upgraded it AGAIN, ha). I have EMF filters in my bedroom at home (I could do more, but financially it's a slow process), but still have wifi there as well (as my significant other isn't as biohacker-esque as I am). I'm curious about what Schumann Resonance devices you might recommend, or if you know of other devices that might help mitigate some of the EMF that we just can't get away from. I saw a video where you had a bracelet on, but haven't been able to find it online. As always, great work and thanks for looking at our questions!

    1. You should take a look at this video https://www.youtube.com/watch?v=ferxd36h07M it’ll give you some ideas. This is the wristband http://superhumanencoder.com/ but we’re currently sold out.

      1. logam11 says:

        Ben, the Superhuman Encoder URL doesn't load.

    Here's an article about the death of Google Glass: http://www.nytimes.com/2015/02/05/style/why-googl…

  21. jeanneloca says:

    I have been trying to listen to both sides of this argument for years but I'm still not sure whom to believe. I did a little experiment, though. I have a Trifield Meter that measures magnetic fields, electric and radio microwave. I also wear a fitbit charge. The meter does not pick up any magnetic activity with the fitbit. One thing I have noticed — at least on my iPhone 5–is that the meter STILL picks up some magnetic activity even when the phone is turned completely off. Of course, the activity is much higher when it is turned on but turning off WIFI actually made the magnetic activity increase. I'm not a scientist and I don't play one on TV but, for now at least, I am going to keep my cell phones and iPads, etc out of the bedroom and away from my body as much as possible but I am not worried about my fitbit.

    1. markberman123 says:

      Hi,
      I have a little EHS and these help me very much.
      I use these and they are great!!

    2. Natalie says:

      I am so curious about the WiFi setting and how your meter picked up more EMF with it off? Also, I am contemplating buying a FitBit, but am struggling because of the EMFs. Any advice would be greatly appreciated.

  22. havequestions says:

    What are the relative merits of ferrite beads on conventional headphones vs. airtube headphones? Do ferrite beads work nearly as well?

    1. Ferrite beads mean you still have a wire going up to your skull vs. a tube. And they are unwieldy and clunky in my opinion. I have a few in my bag but rarely use them just because the airtube headset works so well…

  23. Paul says:

    One last thing I wanted to mention and I like to tell people about this whenever they may need a phone for emergency. In order to get the most range out of your phone you should hold it away from your head and put it on speaker or wear a Bluetooth device the hold it at the end of your fingers kind of like a statue of liberty pose with the mobile phone being the torch . The reason why is because the body does absorb and block signal going bidirectionally. So if you’re in a bad coverage area this can effectively increase your range by about one-fourth to one-third depending on the area conditions morphology terrain and proximity to a cell site.

  24. Paul says:

    Cellphone Emissions: The in-band electromagnetic energy that is produced by the phone is necessary in order to transmit the signal to the radio tower receiver that belongs to the phone carrier. Any effective method employed to impede that signal is going to reduce your ability to connect to your network. Conversely it can block the signal from the radio network to your phone. The radio network is designed with a specific link budget uplink/downlink in order for you to properly operate the mobile phone in their network. One other thing then you talked about a shield that you used on the back of your phone to reduce the amount of energy that goes into your leg when you’re carrying your phone around. I was wondering if you thought about where that energy goes to if it is properly redirected somewhere else. Well if it does reflect it’ll reflector out to your head.

  25. Paul says:

    I have been in the business of designing and optimizing radio systems since 1993 when we moved from analog to digital. In addition I’ve been wearing bluetooth headphones continually and a had mobile phones attached to my body for most of that time. I would say my bluetooth experience started around 2001. So you could say I’m a living guinea pig. I’ve discussed this article with a number of my friends in the industry and I have to say we’re all kind of laughing at you guys for all the hype that comes along every few years. Now I listened to the good doctor talking about people industries making money and I have to say that his side of the fence will wind up being litigation and expert witnesses and research grants all pointed towards him so it’s very apparent that there may be a motive on his behalf as well. I listen to him and he sounded more like a zealot rather than somebody that was actually disgussing facts and when he points to studies he really doesn’t say much about the study itself. under what conditions ? Rambling on about amplitude , Power, modulation and EMag waves he sounded very disjointed, a bit incoherent. Perhaps he was just excited about the whole thing so I think that he’s not quite as sharp on the Radio science as he leads one to believe. One can write a lot of articles but how many of them are critically aclaimed in scientific peer reviewed journals? So I’ll be happy to go ahead and read some of what the good doctor is pointing me to, however, I think he is very inflammatory and very hyping using words like microwaves in order to elicit a response from people that don’t know any better and that house somehow we are tuned to natural Electromatic electromagnetic spectrum. So I will try to leave some of the neurophysiology to the doctor however I would appreciate that he stays out of Practicing plastic surgery and electrical engineering as being some kind of expert because he’s clearly not. And I’ll try not to tell him about neurophysiology. Unfortunately I’m not on vacation and I’m in the middle of a very hot 4G build out for a major radio system carrier. However I will in my spare time due diligence and examine these so-called studies. But I want the general public to know that I’ve lived in Bathed in this stuff for years and I’m on the top of my game plus I’m an athlete and I workout at 56. The most important thing is that people more attuned to their diet to exercise then worrying about ultra-low-power pulses given off from these wideband extremely low energy sources. Besides I can tell you if you want to get some jolt out of energy please stand in front of an automobile with the hood off to kill you pretty good right there. As far as why we use the frequencies when using bluetooth has a lot to do with FCC, and also the fact that the shorter wavelengths allow for a more compact antenna. Also the power and mobile devices as well as wearable devices keeps getting lower and lower and the spectrum keeps getting fatter. And the other part that they seem to miss is that with the better design of receivers and antennas the power output of the device becomes lower not so much out of health concerns but out of battery consumption concern. After all we would like for a headset to all day long as we need. And there’s a few other small issues that should be cleared up as well. Besides there are a number of studies that have been conducted since the 1950s on electromagnetic spectrum and animals in terms of harm on animals. And as far as cooking people’s brains please look up the maximum RF absorption rate of water at frequency and also the amount of energy that has to be pushed into that microwaves cook because they’re able to vibrate water molecules at extremely high rates and that’s because it touches the resonant frequency of the water molecule and causes it to shake violently hence that the heat that is created . Again it’s always nice to be skeptical however the doctor speaks like a person in panic like we’re all going to die in 5 minutes. And I’m smelling a profit motive. Global warming anyone?

  26. tdolanguage says:

    After hearing this, do you still recommend the beddit ap?

    1. I recommend it for quantifying sleep for a week or so if you are tracking your own sleep so that you can see how you sleep hygiene and sleep quality is. Then, just like tracking diet, no need to go overboard and track the rest of your life. My clients track because in my opinion, since Beddit isn't something you're "wearing" and is under sheet, the pros out weight the cons in terms of me being able to see my clients' sleep patterns…

  27. dnd1980 says:

    Was very interested when I saw the topic being presented here. I, like millions of others use a FitBit or other such device and want to know how safe these are when worn daily. Three things frustrated me about this podcast:
    1) I am not an electrical engineer & wanted easy to understand facts.
    2) The guest expert did not sound sure of what he was presenting from start to finish.
    3) Isn't taking the word of someone in the presenter's field a little like taking Monsanto's "research" about GMO safety as the GOSPEL?

  28. Rick Clark says:

    Ben, I really enjoyed this podcast, on a topic of huge concern to a lot of us.

    But can I just say: The speed of light is 186,282 miles per SECOND…not miles per hour.

    I probably deserve a propeller hat for this comment. :-)

  29. Cakebread3 says:

    Holy crap! I've had a FitBit strapped to my body for the good part of a year and a half. I'd like to know if it's constantly transmitting or if it only "turns on" when I'm syncing to the app.

    1. That is a great thing to contact FitBit about. We need to let the companies know that this is a concern for us as humans.

      1. Cakebread3 says:

        I received a reply from FitBit about this and they said that the device outputs a signal every few minutes "but it is minimal". They also directed me to a forum in the FitBit website where this is discussed.

        This from FitBit's in the forum:

        "We've found the radiation emitted from Fitbit devices to be minimal.

        Consider that your tracker's power output is extremely low: less than 1% of the typical output power for a cell phone. Further, a good deal of research has been done in the field of Bluetooth radiation dangers to humans, and the consensus is that the 800MHz – 2 GHz radiation output of a Bluetooth device is negligible to users.

        In short, we do not believe there is any cause for worry when it comes to radiation from our devices. We hope this allays your concern, but please feel free to contact our team at http://contact.fitbit.com if you have any questions."

        >>> Another user posted this response which I found useful:

        "Disclaimer first: I'm not a scientist or health care professional. That being said, the amount of power driving the bluetooth signal is so small that it would be no stronger than what you're exposed to with normal radio waves passing through the air.

        I endured a surgery for an Acoustic Neuroma 7 years ago, which I attribute to extensive Motorola brick style cell phone years ago. The power on those phones were in the 3-5 Watt range and the signal was analog. Being a amateur radio operator, I should've know I was cooking my head with that thing.

        However, with bluetooth, and with the cell phones we use today, the wattage is hugely reduced and the signal type is digital. I use a bluetooth headset all the time for phone and for listening to music, and I have no problem with wearing my fitbit Force constantly.

        Here's an article that discusses this if you want to start doing your own research. http://www.radiationtalk.com/info/bluetooth_radia…

        Hope that helps."

        1. Nice work! Thanks for sharing.

  30. MatthewTS says:

    Hey Ben- wouldn't your Lapka EMF device be able to tell you whether or not a Bluetooth device is transmitting? It seems if you had it near your Fitbit or headset you would be able to see if the signal is constant or intermittent. I use a Jawbone UP 24 that I wear all the time, but I keep my phone in airplane mode and only turn on the Bluetooth a couple times a day to let it update. I'm hoping this is effective, but perhaps it's transmitting all the time whether or not it's connected to the iPhone via Bluetooth. Would the Lapka be able to tell me this?

    1. It probably could. I'm going to experiment with this and will also be asking the guys at Lapka about this!

  31. TrickiDicki says:

    I used to use a bluetooth adapter in the car to listen to your podcast but I could 'feel' the effects of the EMF on that side of my body so ripped it out. I still listen in the car but it's hard-wired, which looks crappy but doesn't impact my wellbeing.

  32. OwenMarcus says:

    Ben, thanks for championing the impact EMF’s have on us. Ever since the advent of electricity, we have avoided exploring the effect our discovery.

    Thirty-five years ago, Jim Oschman PhD told me there was no good distance, good electrical, or radiation device. Jim walked away from a promising career as a biologist after meeting Ida Rolf, PhD to explore the biological impact of EMF’s. He went on to be one to do studies with NIH. Today he’s the scientist championing earthing.

    Like you, I’ve never had Wi-Fi in my home. Recently I made my non-Wi-Fi life easier when I set up a TRENDnet Powerline Nano Adapter Kit. Now my internet travels through my house wiring.

    Before I healed my Asperger’s Syndrome and dyslexia, I was a dowsing rod for EMF’s. Walking into a store like Walmart was walking into a stupor. I felt firsthand what Jack spoke about. For decades, clients came to me with unexplained symptoms. For some removing their EMF exposure was what shifted their health.

    No one can perform at their highest level if their body is being torn down by EMF. Keep up speaking up. We are only seeing the beginning of the effect of the electronic life we live.

  33. wackerb says:

    None of the devices you mentioned are designed to create electromagnet fields so you are safe from the concerns of this podcast. That being said, though, anything using electricity creates some EMF, including the wiring in our buildings, all electrical appliances, power lines, etc. Ever wonder why touching an open input on an amplifier cause that loud 60cycle hum? That is your body acting as an antenna receiving 60hz from all the wiring around you. Since living in the middle of nowhere is not an option for most of us and even then you're going to get some emf from satellites (including GPS's), the only solution I can think if is a Faraday cage (look it up on the internet).

    1. javimei says:

      Well put!

    2. There are some solid ideas in this podcast, that don't involve moving out to the middle or nowhere – https://bengreenfieldfitness.com/2013/12/build…

  34. wackerb says:

    I started off in Physics and graduated in Political Science, but I've never heard such a muddled misunderstanding of wave physics. First, 910Mhz is 0.91 Ghz so not that much difference to 2.4Ghz. The criticality of GPS timing, probably to account for transmission time from satellite to earth, has nothing to do with whether or how electromagnetic radiation affects biological systems. As for pulsing, the frequency and amplitude of the pulses are critical, but no distinction is made. Also, is the modulation by AM (amplitude) or FM (frequency) pulses. Finally, devices to measure all aspects of radiation are pretty cheap and probably in most university physics labs. Rather than bemoan the lack of labeling, just measure the things. Maybe even get political and force UL to do it. You need to get a qualified radio physicist on to clear up the misconceptions. Note, this is not to say non-native EMF is not bad for you, but no educated person will accept such confused logic.

    1. keremyb says:

      thank you! my thoughts exactly. I actually decided that I had to sign up to create a comment to say what a waste of time this long podcast was.

      ben we expect you to have a better understanding of what you are talking about if you are really going to say you're making a podcast and answering questions about things.

    2. Thanks. THIS is the type of information I'd love to learn more about. If you're interested in contributing to a guest post on the topic, or enlightening me more on the matter, please email me: [email protected]

      1. BobD says:

        Not true Ben , other wise you would just have a podcast on how Bluetooth is safe.

        1. I'm not taking any chances myself….

          1. Ken Allen says:

            What’s Watch class? 1 2 or 3??

          2. Believe that one is a class 1.

  35. That part is up to you! I just want to ensure that you are making an informed decision about what is "worth it" and "what is not" in your own life. For me it is all about moderation and balance… with a modicum of abstention ;)
