What does a low HRV during recovery really mean for my nervous system?

I’ve been tracking my HRV for months now, and while the numbers are decent, I can’t seem to shake this feeling of being wired but tired no matter how I tweak my sleep or exercise. I’m wondering if that persistent low-grade stress reading means I’m missing something in how my nervous system is actually recovering.

I've been there. My HRV numbers looked fine, but that wired-tired vibe stuck around. I tightened up sleep timing, moved workouts earlier, and tried a tech-free wind-down, yet the edge stayed. Lately I focused less on the graph and more on how I actually woke up: if I felt usable or still twitchy, that felt truer than the last score.

From my own trying, HRV is a signal but not the whole story. A rough pattern I noticed is after a stressful few days, recovery looked okay on paper but I still felt drained. I started small breathing drills and gave myself longer cooldowns, hoping for parasympathetic drift, but the gut feeling of being wired lingered even after workouts halted.

I began suspecting sleep quality issues rather than duration alone—like REM fragmentation or night waking. I experimented with earlier bed, dim lights, and quieter room; sometimes it helped a bit, sometimes not. The sense of being primed stayed stubbornly, even with what seemed like good sleep.

Maybe we’re chasing the wrong culprit. Could it be simple things like caffeine timing, dehydration, gut signals, or ambient light and noise? I asked a clinician and they suggested looking at total load and other signals beyond the numbers, but I’m still unsure what to trust.
