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, across the Seven Recovery Systems, and checks them against readings taken in the Sleep 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 show trends well, but not exact sleep stages.
We treat every number as a trend against your own baseline, not an exact measurement.

What we do, and don't, use wearable data 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
The device names and models shown here are examples and can change. Bring the devices you already use. You don't need to buy anything, and consumer sleep-stage estimates are not a diagnosis.
