Overnight physiology
The smart ring
- Resting heart rate
- Heart-rate variability
- Skin temperature trend
- Respiratory rate
- Sleep stages are estimates
- Short awakenings under-counted
Wearables
Three devices you already own, read as one signal.
A ring, a watch and a phone each measure something the others cannot. Sleep Week reads them together and checks them against measurement taken in the suite.
What each device is good at
Different sensors, different jobs.
Daytime load and timing
The watch
- Movement and activity
- Daytime heart rate
- Wake time consistency
- Blood-oxygen trend
- Motion artefacts at night
- Wrist temperature is noisier than finger
Behavior and environment
The phone
- Light exposure timing
- Screen use before bed
- Room sound and noise events
- Daily check-ins
- Position-dependent audio
- Self-report is subjective
Signal quality
Consumer trackers are good at trends, weaker at stages.
Every number is treated as a trend against your own baseline, not an absolute measurement.

Guardrails
What wearable data may and may not be used for.
Used for
- Comparing your own nights to each other
- Detecting timing and consistency patterns
- Flagging signals that warrant clinical review
- Measuring whether the take-home plan holds
Never used for
- Diagnosing sleep apnea or any sleep disorder
- Changing prescribed therapy or medication
- Replacing formal in-lab diagnostic testing
- Emergency or urgent symptom assessment
Device names and models are illustrative and administratively editable. Bring the devices you already use; nothing is required to purchase, and consumer sleep-stage estimates are not diagnostic.
