What can actually be tracked
Burnout is a state of exhaustion, detachment and reduced effectiveness caused by chronic work stress. No app measures it directly. What you can track are signals that often move before it:
- Resting heart rate creeping up over several weeks.
- Heart rate variability (HRV) trending down, if your watch records it.
- Less recovery during the day: heart rate that no longer settles between meetings.
- Work spreading: evening and weekend events on your calendar.
- Sleep: a higher overnight heart rate than your usual.
Why the calendar matters
A rising resting heart rate on its own could be a cold, heat, alcohol or less exercise. Next to your calendar, the explanation is often clearer: the weeks it rose are the weeks you worked late three nights running. 70 BPM shows the heart rate your watch already recorded against your calendar, day by day, so the connection is visible.
A simple weekly check
- Look at this week's typical daytime heart rate against last month's.
- Count the days you got a real recovery block (no meetings, heart rate settled).
- Find the single most expensive event of the week.
- Change one thing for next week and check again.
What a tracker cannot do
No tracker can tell you whether you are burned out, and a normal-looking chart does not mean you are fine. If you feel exhausted, cynical about work or unable to switch off for weeks, talk to a doctor, a counsellor or someone you trust. Data is a prompt, not a verdict.
Not medical advice. 70 BPM shows heart-rate data your watch has already written to Apple Health. It is not a medical device and cannot diagnose anything. If your heart rate is often high at rest, or you have chest pain, dizziness or breathlessness, talk to a doctor.
