Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This will be a single-center, prospective observational study designed to evaluate the feasibility and accuracy of a new wearable device for non-invasive continuous monitoring of physiological signals to derive circadian rhythm. Melatonin sampling will be included for comparison against wearable-derived measures

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Adults ≥18 years at screening.
* Able and willing to provide written informed consent.
* Belonging to one of three strata: (a) healthy controls without diagnosed sleep disorder, (b) patients with physician-diagnosed OSA, or (c) patients with physician-diagnosed insomnia (based on DSM-5/AASM criteria and ISI ≥15)
* Capable of using a smartphone for app-based data syncing.
* Willing to comply with study visits, wearable use, and saliva sampling.

Exclusion Criteria

* • Dermatologic conditions preventing wearable use.

* Significant psychiatric or neurologic illness that may impair compliance.
* Shift work or trans-meridian travel within 2 weeks prior.
* Currently pregnant
* Use of medications known to significantly alter circadian rhythm (e.g., exogenous melatonin, beta-blockers).
