If the watch is worn all day, are there long-term effects on the body due to the permanently active Bluetooth and Wifi connection and all the radiation?
During training I usually use a Polar chest strap to measure heart rate (also with Bluetooth), but it is not worn every day and all the time.
 
No. Bluetooth and WiFi radio waves aren’t much different from the hundreds of other radio waves that are around us constantly.

No. Bluetooth LE is an extremely low energy RF emission. Apple Watch wifi only becomes active when it loses its Bluetooth connection. Otherwise, the watch's wifi is off to save battery power. Cellular on the LTE-enabled watches works the same way -- even if left "on", it only activates if the watch loses BT and wifi (the watch's battery simply cannot power the LTE and wifi antennas all day long). There's 10-100x less RF energy emanating from the watch than there is from the phone in your pocket.

It's also non-ionizing (non-ionizing radiation doesn't cause DNA damage) and you're exposed to far more background ionizing soil radiation (natural isotopes like radon), solar radiation (UV, x-ray, gamma ray) and cosmic radiation (high-energy particles) annually, not to mention medical sources of radiation, than in a lifetime of wearing an Apple Watch.

Wearing an Apple Watch is safer than most other things you will do in your life.
 
Seems to be questionable
You might want to try using a source other than one from a government agency funded by big tech... just saying ;)

Apple (and all the other cell phone manufacturers) includes that legal document with every phone they sell for a reason. If you choose to ignore it then that's fine.
 
a study bases in Sweden ran a test on those bluetooth ear plugs and stated they are harmful under continuous use, which was published via NYTimes in 2002 (article deleted- unarchived)

every time i post this study, im told to "educates me-selfs" and other hateful remarks.
so im not saying anything, your ears, your life!

Hey, there is a sale on those ipudnanopro elite on teh_amazons!

Cellphones (microwave RF) are a slightly different issue insofar as oncogenesis (tumor forming). While the radiation itself is not ionizing, there is some debatable research that suggests that mild chronic tissue heating could cause long term formation of heat-shock proteins which potentially could result in tumor formation. The evidence is far from conclusive and requires durations and energy generally much higher than the average person would be exposed to.

Thus it may be prudent to not have an active cellphone plastered to your head 24/7/365 for years on end. But the evidence is not in any way conclusive.

However, the total energy of Bluetooth devices is far too low (and at a suboptimal frequency) to result in any tissue heating.

While I don't doubt that the NYT ran an article that said this, the evidence to substantiate this is pretty poor. And the NYT is not exactly considered a peer-reviewed source. And to be honest, which would you rather have next to your head -- microwaves with enough power to have a range measured in 10's of miles, or lower frequency radiowaves with ranges measured in 10's of feet?

The wifi antenna in your laptop's lid is exposing you to more RF energy than any set of BT earbuds.

Sorry, not drinking the kool-aid today, but by all means enjoy it if you please.

I'll stick with peer-reviewed studies.

It's very simple to me, If word got out that cellphones caused cancer, all these high-tech companies would lose Billions (with a B) dollars, so of course they want to downplay it. How you use your cellphone is your business. A cancer cell could care less what anyone thinks.

And there's plenty of peer-reviewed studies that show very low correlation. So like I said, things are far from conclusive. I'm not discounting the study (studies) that I'm sure you've got links to, but there are just as many that show the opposite (and that are not funded by tech companies). But I did say it's probably more prudent to not keep your phone attached to your head continuously.
There's far too much active research to believe in conspiracy theories, however, that tech companies are behind a giant coverup.

If it was properly tested by a reputable lab and hasn’t been damaged, then you are most likely fine. The US and European regulations, at least, are pretty conservative, erring on the side of caution.

And please, nobody say it’s because WiFi is non-ionizing... That’s not the reason.

So because you don’t want to “drink the koolaid“ offered by a government agency, you cite a report giving partial results of studies for a government agency (the NIH) on rats using different frequencies than those being discussed here?

The FCC SAR limit is 1.6W/kg, this study was exposing rats in utero and then while breast feeding at exposure levels up to 6W/kg. This was whole body exposure, in a chamber, for 18hours a day, every day, for 2 years.

Then, most interestingly, there's this:
At the end of the 2-year study, survival was lower in the control group of males than in all groups of male rats exposed to GSM-modulated RFR. Survival was also slightly lower in control females than in females exposed to 1.5 or 6 W/kg GSM-modulated RFR. In rats exposed to CDMA-modulated RFR, survival was higher in all groups of exposed males and in the 6 W/kg females compared to controls.​

There was a slightly elevated number of heart problems (not near the wrist) only for male rats. The study indicates this might be due to the fact that 30% of the control rats died before the health effects would have been seen. Female rats didn't see any notable biological effects.

Sorry, this isn't the kind of study that's going to keep me up at night. I'm not a newborn rat, I'm not living in a microwave, and if I was then this study still seems rather inconclusive.

Great, happy to hear it. Like I said, a cancer cell could care less what anyone thinks. Everyone has the right to believe anything they want. The great thing about science, though, is that it’s true whether you believe in it or not.

It was also only partly 'published' (not peer reviewed) in 2016. If you look up the follow-up, there's even less correlation. And as with almost all of these studies, the energy levels used far exceed the periodic exposure in real-world scenarios.
 
There's a reason why all cellphones, including iPhones, come with a warning insert that says not to place the phone next to your head.

I’ve owned mobile phones for over 20 years (over half my life) I have never seen a warning not to put it next to my head. It’s only been the last few years where using a phone not next to your head has been possible really.
Where are these warnings exactly and why do they advertise with people holding them next to their heads?

They all do, actually, to be perfectly fair.
Here's Apple's notice for the iPhone 11 Pro:

iPhone 11 Pro RF Exposure Information​

iPhone has been tested and meets applicable limits for radio frequency (RF) exposure.

Specific Absorption Rate (SAR) refers to the rate at which the body absorbs RF energy. The SAR limit is 1.6 watts per kilogram in countries that set the limit averaged over 1 gram of tissue and 2.0 watts per kilogram in countries that set the limit averaged over 10 grams of tissue. During testing, iPhone radios are set to their highest transmission levels and placed in positions that simulate uses against the head, with no separation, and when worn or carried against the torso of the body, with 5mm separation.

To reduce exposure to RF energy, use a hands-free option, such as the built-in speakerphone, the supplied headphones, or other similar accessories. Cases with metal parts may change the RF performance of the device, including its compliance with RF exposure guidelines, in a manner that has not been tested or certified.

Although this device has been tested to determine SAR in each band of operation, not all bands are available in all areas. Bands are dependent on your service provider’s wireless and roaming networks.
The highest SAR values are as follows:

Model A2215​

1.6 W/kg (over 1 g) SAR Limit
Head: 1.18
Body: 1.16
2.0 W/kg (over 10 g) SAR Limit
Head: 0.99
Body: 0.99

Model A2216, A2217, A2160​

1.6 W/kg (over 1 g) SAR Limit
Head: 1.16
Body: 1.18
2.0 W/kg (over 10 g) SAR Limit
Head: 0.99
Body: 0.99

That’s not a warning to not put it to your head though.

Obviously some will interpret this differently since it's basically instructions to reduce RF exposure. I didn't read through every single version for each iPhone, so maybe some of the older ones had different language. And I don't know what other manufactures say specifically.
You and I are on the same side, but I was just being honest as to what one of the other posters said.
Best way to reduce one's RF exposure is to not stand on the surface of the planet anywhere near civilization or whenever that big star in the sky is visible.
