Apple watch gives pain on the wrist?

According to this Wikipedia article it does appear that the scientific community has done tests to determine that it is not possible to detect radio emissions of the kind that Bluetooth emits. However at least I am providing scientific references here instead of just throwing accusations around. My point was just to respect someone's personal experience until you have proof otherwise. Here's the proof otherwise, and I'm perfectly happy to change my stance based on evidence. However everyone else was just throwing accusations around without any basis or links or proof whatsoever. Next time you start making accusations and claims, try backing them up with evidence instead of just hearsay.

I believe the alien abduction analogy holds here as well. It's up to the person positing a theory to provide the citations. If someone starts saying they were abducted by aliens, are you suggesting that everyone else needs to cite evidence to the contrary before suggesting that they are mistaken?

Sorry, Wikipedia doesn't cut it as a scientific link. I never said there were no emissions from BT. What I said was it is non-ionzing as has Meg. And I discounted his story as it wasn't logical. And still isn't. I also discount birthers, truther, and Dr. Mercola adherents.

Aw, deggie, you've gone and hurt Wikipedia's feelings. And possibly damaged its self-esteem.

I seem to be on a roll doing that today except with my friend Zealand. But he is only 4 months old and smiles and drools on me.

Babies (at least other people's) are loads of fun that way.

My brother is a middle-school math teacher. The whole "self-esteem" thing makes smoke come out of his ears. He believes self-esteem derives from accomplishment, not from having every effort win a trophy.

If you'd bother to look at the wikipaedia page you'll see that by the magic of these things called hyperlinks they actually link to the double blind studies I'm referring to. Odd that even when I support your view that you site all sorts of whackos in your reply. Just remember, "you're right." That's all your precious little ego needs to know.

And if you were capable of rational thought, you'd realize that the "studies" are pure crap.

Hi there. I believe that I am experiencing a painful 'pressure' in my head (left side, at the front) which occurs quite quickly after wearing the watch and turning bluetooth on, on my phone (it is usually off). When I bought my 38mm Sports I didn't realise that it used Bluetooth to work, I thought it used wi-fi only (my mistake..). I have found for some years that I am clearly hyper-sensitive to bluetooth 'pulses', which was shown to me again when I borrowed someone's wireless mouse the other day and got the same thing after about 5 minutes. I also get it when using my wife's car - the car searches for her bluetooth phone, and because it can't find it, I think it ramps up the signal strength and then I get the buzzing in the head. After a minute or so the car gives up so then normality returns!. By the way, @Deggie, I think this is physiological not psychological - I'm not making it up, and I don't like your suggestion that I am 'talking myself into this'. We know that there are people with great palates, great acoustic ability, great sense of touch, great eyesight, so it's not a surprise that some of us cannot cope with certain types of electronic emittance so close to the body and others don't notice it. I had one day of not wearing the watch and was fine, then a day with it and lo! there it is again. In fact, I felt a pulse in my brain about 2 secs before I heard the alert on the watch - that must be the signal from the iPhone to the watch. I first noticed this similar feeling about 10 years ago with a Siemens phone when I got it and did not even know what bluetooth was. After a week I had to give it back. Anyway I digress. Reluctantly I think the Watch is going to have to go back next week, as I cannot wear something that after about half a day is giving me a pain in the brain and making me feel nauseous. Is anyone experiencing this type of issue?

Call me a tinfoil hat too then, because I am experiencing the same nauseous/dizziness feeling when bluetooth is turned on my iPhone. I especially felt it the night I was transferring over 1GB of music from my iPhone 6 to my apple watch, there is something about bluetooth that causes discomfort w/ my body, especially when there's high amount of data being transferred. Like Winerunner, sometimes I can feel when the apple watch is about to alert me of something because the discomfort intensifies. If I disable bluetooth and put my phone in airplane mode, all this discomfort disappears. You can say all you want about how there's no scientific claim on everything I've stated, but I know I'm not crazy and there are people that is affected by this issue, very limited amount of people based on my research but nonetheless, there are people that are affected by it.

A Bluetooth signal remains the same regardless of whether you are sending a lot of music or just getting an email. It isn't like a faucet where it goes up in intensity. Considering all the people with wearables, smartphones, BT music devices, BT headphones, Beacons and WiFi hotspots you must get no relief at all.

Wifi and Bluetooth both transmit at the same maximum power level (100mw) and in the same frequency range (2.4 to 2.8ghz). The only difference I can find in the transmission method is that WiFi uses a single channel whereas Bluetooth is a 'frequency hopping' system.

The signal must obviously change to carry the data it's transmitting. Whether if it intensifies or not, I dunno because I'm not an expert on radio waves but I'm certain the wave is different between two BT connected and sitting in idle and two BT connected and transmitting information... it has to be in order for data to be transmitted. I don't have issues with WIFI, I've been using a WIFI router at my house for over 15+ years. I only get discomfort when I'm in close range of a bluetooth device that is enabled and I don't know why. I'm sure a lot of people don't have issues with bluetooth or else we'll have more stories such as mine, but I'm just here expressing my experiences with bluetooth. Obviously I'm not the only person that is sensitive to it.

No, the signal does not change it is just on longer. As Csound1 pointed out above there isn't really an appreciable difference between the two types of signals.

As Kilted Tim has pointed out no verifiable tests have found such a "sensitivity" to be valid. If you truly believe you have this then you need to get rid of any devices you have that have Bluetooth (or permanently turn off Bluetooth) and stay at least 30 feet away from anybody else using a Bluetooth device.

Uhh...... but there is a difference as Csound1 pointed out "The only difference I can find in the transmission method is that WiFi uses a single channel whereas Bluetooth is a 'frequency hopping' system".

A quick google search came up exactly what he found - "Frequency Hopping Spread Spectrum (FHSS, used by Bluetooth devices) and Direct Sequence Spread Spectrum (DSSS, used by Wi-Fi devices)" http://www.ecnmag.com/articles/2012/03/wi-fi-and-bluetooth-coexistence

That really would make no difference whatsoever if the non-ionizing radiation from either system was emitting something that would make you sick, that has to do with the two signals not interfering with each other.

Going back to Bluetooth, I take it when you are out among people this sickness is pretty much omnipresent?
