The Overnight Oxygen Workbook

Self-experiments to run with your tracker, in the app and as a PDF.

Updated 2026-09-14

Not a medical device. Does not diagnose, treat or prevent any condition. Discuss results and changes with a clinician.

The Overnight Oxygen Workbook is a short guide to self-experiments you can run and log with your tracker. It is included with lifetime access.

What is inside

  • 15 numbered steps, in order from changes that tend to show up in your data within a few nights to changes that take weeks or months to show as a trend.
  • When to talk to a doctor, covering patterns in your data that are worth discussing with a clinician.

Each step says what to try, which numbers to watch (ODI, SpO2, T90, nadir, desaturation count) and what published studies found. A two-week experiment log and a numbered reference list are at the back.

Read it or download it

  1. Open the dashboard and choose the Workbook tab.
  2. Read it in the browser, or select Download PDF to save an A4 copy you can print.

Tag the nights you try something with an event, then use the impact view to compare them with the nights you did not.
