Episode notes
Use Wearables For Trends, Not Staging
- Treat wearable sleep data as trend indicators, not perfect staging tools.
- Prioritize how you feel in the morning over exact device-reported sleep stages.
Check Oxygen Levels At Altitude
- At altitude, monitor oxygen saturation during sleep to detect periodic breathing or apnea.
- Adjust camp altitude or duration if sleep-disordered breathing severely disrupts adaptation.
Keep A Simple Sleep Diary
- Track subjective sleep with simple diaries and targeted questions like sleep duration and daytime sleepiness.
- Use questionnaires and compare subjective logs to objective data to spot mismatches.
