Hey everyone remember how we slept before devices "helped" us do it? You know, get tired, go to bed, close eyes... and pretty soon like magic, there it was, sleep, and waking up the next morning. Those were the days!
Seriously if you use devices for sleeping you should know that the EMF from your WiFi and that 4G tower nearby is going to disturb your sleep more than the device can possibly help. Turn off WiFi and put it in airplane mode at the very least.
As for the watch and airpods, don't go and intentionally fry your brains for no reason please?!
So for heaven's sake do not sleep with a freaking bluetooth / wiFi / LTE watch on! Do some research on EMF, or, more efficiently, simlpy try it for yourself.
Sleep without any EMF for a few nights (WiFi router OFF too) - and see how it goes. You will notice a difference. Just try it!
