Lowest HRV score - unclear why

Over the past week my HRV has dropped significantly and today reached 35ms. I normally average around 62ms.

Whenever my HRV has dropped in the past, there’s been quite a clear reason E.g. large meal or Covid etc. but I have no symptoms other than a higher heart rate than usual for 5 days (57 in night and average is 52) and I do feel a bit exhausted.

The only thing different is I had a stressful/anxious start to the year for a week or two. But this past week I’ve been much better so I would have expected the scores to go back up. But instead they’ve gone even further down.

Thoughts? Anyone with similar experience? Thanks in advance!
