Mathias Baumert, biomedical engineer from the University of Adelaide with expertise in sensors and algorithms. Cathy Goldstein, neurologist from the University of Michigan focused on clinical and regulatory perspectives. Michael Chee, sleep researcher from the National University of Singapore who led wearable guidance. They discuss regulatory boundaries, practical limits of wearables, TATS (time attempting to sleep), validation needs across populations, and future sensor applications.

Episode notes

ADVICE

Use Wearables To Augment Care

Use consumer wearables as adjunctive tools for awareness and behavior change, not as standalone diagnostic devices.
Guide patients to act on long-term trends rather than single-night readings.

ADVICE

Trust Validated Clinical Metrics Only

If a device outputs a clinical metric (e.g., AHI), confirm it was validated against a gold standard like PSG.
Otherwise treat it as a wellness metric and not a diagnostic result.

INSIGHT

Focus On Fundamental Sleep Measures

Fundamental sleep measures (timing, TST, efficiency) are the most reliable outputs from consumer devices.
Sleep stages like REM or deep sleep are less reliable and should be deprioritized clinically.

In this episode of Talking Sleep, host Dr. Seema Khosla welcomes three members of the World Sleep Society's consumer health technology task force—Dr. Michael Chee, Professor and Director of the Center for Sleep and Cognition at the National University of Singapore who chaired the guideline-writing task force; Dr. Mathias Baumert, an associate professor leading the biomedical engineering discipline of the school of Electrical and Mechanical engineering at Adelaide University in Australia, and Dr. Cathy Goldstein, professor of neurology at the University of Michigan. to discuss their global recommendations for the use of consumer sleep technology and wearable health trackers.

Consumer wearables have become ubiquitous in clinical practice, with patients routinely sharing device data. While some clinicians have historically dismissed this information, attitudes are shifting as technology improves and rigorous research examines sensors, algorithms, and data quality. Dr. Chee explains that the recommendations are designed for multiple audiences: end-users, clinicians, researchers, and manufacturers, with specific guidance for each group.

The conversation addresses practical considerations: the assumption that users have good perfusion, how bed partners can influence movement detection, and the fundamental truth that the best device is one patients will actually wear properly. The panel discusses recent FDA regulatory changes and clarifies whether guidance applies only to non-FDA cleared wellness devices or has broader implications.

The experts systematically review various metrics from wearables. They introduce TATS (total attempted time in sleep) and explain what clinicians should know about sleep onset and offset detection.

The episode emphasizes the call for standardized Fundamental Sleep Measures and greater transparency about test populations used in device validation. Dr. Baumert discusses the need to co-create benchmarks for measurement accuracy across different contexts—from persons with normal sleep to shift workers to those with sleep disorders.

Whether you're skeptical about consumer wearables or seeking guidance on interpreting patient-generated data, this episode provides evidence-based recommendations for moving forward responsibly.

Join us for this important discussion about embracing consumer sleep technology while maintaining clinical rigor.
