My Samsung Galaxy Ring just called me out for going to sleep drunk — how is it so creepily accurate?

I've been wearing the Samsung Galaxy Ring for three weeks now — and I'll admit that I underestimated it. Don't get me wrong, between my first impressions of the Galaxy Ring and my official in-depth review, it had a cornucopia of impressive perks.

For example, unlike the Oura Ring, it doesn't require a subscription. Secondly, its ability to track my stress has been creepily accurate, with the trend line in Samsung Health (the companion app) spiking during work hours and dipping during breaks.
