What This Calculator Measures

Estimate optimal recovery nap duration based on sleep debt, training load, and timing.

By combining practical inputs into a structured model, this calculator helps you move from vague estimation to clear planning actions you can execute consistently.

This calculator estimates a nap duration that balances recovery, timing, and sleep debt.

How to Use This Well

  1. Enter sleep debt and training load.
  2. Set nap window and time of day.
  3. Add caffeine cutoff and stress level.
  4. Review nap duration and recovery boost.
  5. Adjust window if needed.

Formula Breakdown

Nap = base + load + debt
Base: 15 minutes baseline.
Load: adds minutes per 50 load.
Debt: adds minutes per hour.

Worked Example

  • 1.5 hours of debt adds ~9 minutes.
  • Training load adds a few minutes.
  • Nap stays within the available window.

Measurement Notes

Treat this calculator as a directional planning instrument. Output quality improves when your inputs are anchored to recent real data instead of one-off assumptions.

Run multiple scenarios, document what changed, and keep the decision tied to trends, not a single result snapshot.
