Can a watch reveal hidden sleep troubles in POTS patients?
NCT ID NCT00692471
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study uses a wrist-worn activity watch to measure sleep quality in people with orthostatic intolerance (a condition where standing causes dizziness) compared to healthy volunteers. Researchers want to see if these patients have worse sleep, like taking longer to fall asleep. The study involves 100 adults aged 18-65 and is purely observational, aiming to gather knowledge rather than test a treatment.
