One year of sleep, movement and recovery—made more useful by looking at what changes together, and what doesn’t.
No need to hunt for the numbers that matter.
Choose an exported day. Explore the measurements in plain language, with a personal baseline where there’s enough history.
Write what the ring couldn’t know. Notes stay in this browser on this device, are not synced and may be visible to anyone using this browser profile.
Workout distance and calorie estimates are device outputs. Oura’s contributor fields may share inputs with the scores.
One signal rarely travels alone.
These are associations in Jason’s exported days, not experiments. Shared inputs, calendar changes and missing readings can shape them. The initial selected day is an example from July 2025; use the selector above to explore the record.
In 2025, Jason worked overnight at a hospital while holding a remote day job. The ring saw the signals. The schedule adds the context.
Hospital hours were approximately 11 p.m.–7 a.m., beginning around June and ending around September or October; remote work was 8 a.m.–5 p.m. Exact workdays and the end date are unknown. Calendar comparisons do not prove what caused a change.
Average readiness, by calendar period. Read these as chapters, not shift labels.
Readiness is Oura’s estimate, shown on a 0–100 scale. Each average uses only recorded values; counts are shown. October cannot be assumed to be after the schedule ended.
The schedule didn’t just make the days longer. It changed where sleep could fit. Here’s what the export actually shows—and what it doesn’t.
The drop was clear. The rebound wasn’t a straight line.
2025 monthly scores are means of recorded values. November and December have only 11 and 6 readiness days; missing data isn’t a zero.
The two Oura scores can share inputs, so they are not independent tests. The chart needs an internet connection to load its chart library; the data table below works without it.
Longest-session sleep shortened after May; HRV changed differently across months. These series have different units and can have different recorded-day counts.
Monthly values are means of available longest sessions, not 24-hour sleep totals. November and December have sparse recordings; sample counts are available in the table. The chart uses an online chart library.

A calendar of the days in the export. Switch the signal, zoom into any month, and select a day to see its complete dashboard record. A small ✳ marks a day with a recorded workout.
Colour bins are visual groupings, not health grades. — means the selected measurement is missing. A workout marker means the export includes a workout on that day; its absence does not establish that no exercise happened. Dates with no recorded signal are not scored.
Choose a recorded day, compare two windows, or browse the history. A dash means no value was recorded—not zero.
Compare recorded days in two calendar windows. Dates do not identify actual workdays.
| Measure | Period A | Period B | Difference B − A |

Each measure uses available values and shows its own count. Sleep and HRV refer to the longest recorded session per exported day. Differences are descriptive, not causal.

Interesting is good. Defensible is better. Here’s the difference between a finding in this record and research about people more broadly.
Jason’s recorded sleep start times shifted. That is not a measurement of the body’s internal clock. A study of 45 night-shift workers evaluated a model against laboratory melatonin timing; this dashboard applies no such model.
Cheng et al. · SLEEP, 2021 ↗In one laboratory study of 53 healthy adults, Oura Gen 2 had stronger agreement for sleep versus wake than for specific sleep stages. That does not validate every individual reading or daytime shift-work sleep.
Miller et al. · Sensors, 2022 ↗In a controlled sleep-restriction study, measured vigilance worsened across days even as subjective sleepiness changed less. That does not establish Jason’s alertness or performance; his workdays and full 24-hour sleep totals are unknown.
Van Dongen et al. · Sleep, 2003 ↗Same-day steps and readiness are linked differently across periods in this record. Work schedule, missing days and shared score inputs can complicate the relationship; this is a hypothesis generator, not a verdict on activity.
See how the numbers were calculated ↓This is one person’s exported record, not a clinical assessment or a live feed. The dashboard prioritizes daily scalar metrics; high-frequency sensor streams remain in the source archive.
A static snapshot of 400 exported dates and 98 workout dates. The dashboard uses days with at least one dashboard measure. The source archive contains 22 selected Oura app-data files, including high-frequency signals and tags; payment, subscriptions and raw location are excluded. The CSV contains scalar daily fields; the expanded JSON also contains sessions, workouts and separate oxygen records.
Daily sleep duration, HRV, lowest sleep heart rate and breathing come from the longest recorded sleep session on the exported day. The shift insight separately sums non-overlapping sessions; that sum is not necessarily a 24-hour total.
Missing values remain missing. The data do not establish workdays, diagnoses, biological adaptation, causes or training prescriptions. Different metrics can have different sample counts. The studio’s comparison uses the previous 28 calendar days, excluding the selected day, and requires at least 10 recorded values. Different measures can have different baseline days.
