The model

A scientific model, not a quiz

Els built the Sleep Intelligence Profile from her research on sleep and performance. It looks at six principles that together decide how well your sleep works for you. Each one has its own chapter in the book.

The Snapshot gives you one overall score. The full profile scores every principle and shows what to work on first.

  • Quantity

    Whether you sleep enough on workdays compared with your ideal sleep window.

  • Quality

    Whether your sleep feels deep and restorative.

  • Chronotiming

    Whether your days fit your body clock.

  • Consistency

    How regular your sleep and wake times are.

  • Routines

    The habits around bedtime and waking up.

  • Resilience

    How you handle short nights and protect your sleep.
