Burnout, Sitting, and the Feedback Loop No One Talks About
Burnout isn't only about workload. Physical inactivity is a compounding factor most conversations about developer wellness quietly ignore.
The loop
Long sitting hours reduce vagal tone and elevate baseline cortisol. That physiological state feels like low-grade anxiety, which reduces motivation to exercise, which further reduces vagal tone. Repeat for months.
By the time it feels like burnout, the body has been priming the pump for a long time.
The smallest useful intervention
Zone 2 cardio — an easy pace where you can still hold a conversation — three times a week for 30 minutes. It's the highest-leverage intervention for restoring autonomic balance and it's boring enough that most people can sustain it.
You don't need to overhaul your schedule. You need three walks a week that raise your heart rate to around 60–70% of max.

What this doesn't fix
Movement helps the physiology. It does not fix a genuinely unsustainable job. If your workload is the problem, walking harder is not the answer — the org is.
