What Is Fatigue Tracking?
Understand fatigue tracking, what it measures, and why baseline comparisons matter.
Track real work periods
Fatigue tracking starts from actual desk work, not a guessed end-of-day summary.
Use one period against another
The useful signal appears when you compare similar windows instead of one noisy day.
Ask better questions later
Once a baseline exists, Hydrogen can show what changed and where it repeated.
It replaces guessing with a baseline
If you remember how a week felt but not how it actually changed, fatigue tracking gives you a repeatable way to compare time periods.
- Reliable minutes
- 312
- Sample tracked minutes strong enough for comparison.
- Afternoon shift
- +27%
- Sample fatigue load change after 2 PM.
- Focus stability
- 64/100
- Sample stability score for the same window.
Look for repeated patterns, not perfect certainty
Good fatigue tracking keeps the first read simple: coverage, repeatability, and whether the same fatigue window appears again.
- Start with 2-3 normal workdays before reading early patterns.
- Use 7-14 days for stronger baseline comparisons.
- Compare similar windows, like morning work blocks against morning work blocks.
- Use the download page when you are ready to capture the Windows baseline.
Short answers
Fatigue tracking measures how your energy changes across real work periods so you can compare patterns instead of relying on memory.
No. Wearables can add context later, but the baseline starts with your Windows work pattern.
It becomes useful once you have enough normal workdays to compare one period against another.
Start with the Windows baseline
Install Sarenica on Windows, track a few normal workdays, and then compare one period against another.
