My watch has same problem. Since Tuesday 24 ago, my watch shows high level stress in the night and my sleep scores are between 61 and 64. Before my minimum score was 74 and my body battery is very low, 40 or less when I wake up.
Many months ago. It seemed I lost deep sleep, much less than say a year ago. This lasted for many months. Now if seems I get deep sleep, like long ago, but at the loss of REM, which now zero. what’s up?
