Historically, people and industries have been in denial (for example, the tobacco industry denying the linkage to cancer). Time will tell if wearables have negative effects.
The tobacco industry denying that tobacco caused cancer is not really an apt analogy. Non-ionizing radiation has been studied independently of wearables (in fact, since before wearable was a word). So, read the actual science, not the marketing.
All I know is that, after a period of time, I can definitely sense the pain when I forget to turn on Airplane mode when wearing the Apple Watch.
However, unless you tested it in a situation where you didn't know if the watch was in Airplane mode or not, conformation bias is a very real possibility. Human brains are remarkably easy to fool. And pain perception can be affected by a large number of factors. Please understand, I'm not suggesting you're stupid. I'm saying the way the brains of our entire species are wired, it can be very easy to make us belief certain things and very hard for us to give up certain beliefs even in the face of very strong evidence.
I had the wrist pain issue with a Fitbit HR (which I stopped using). So this isn’t specific issue pertaining to the Apple Watch in my case.
There are some anecdotal reports about people whose anatomy is just enough different that the convex back of the watch presses against a nerve in their wrist. It's been a while since I closely examined an FitBit HR so, I can't postulate if there is possibly a similar mechanical explanation.
