Nearly seven hours of sleep and morning transition

A night of sleep captured from its early minutes into the morning. Follow heart rate, breathing, and changes in position as the body settles and wakes.

CSV timestamps are Unix milliseconds (UTC); samples retain their recorded values.
ECG: volts. Respiration: ohms (chest movement signal). Acceleration: g, three axes.
Pulse: beats per minute. RR: milliseconds between detected heartbeats.
Body position: numeric code and text label. See dataset.json for signal counts.
RR intervals can be used to study HRV after checking beat quality.
Recording gaps are preserved; no samples are filled in.
See raw_signal_quality in dataset.json for raw coverage and longest observation gaps.
No activity or sleep-stage labels are supplied. License: MIT.
