Your Oura Ring measures skin temperature every night as a deviation from your personal baseline. Vitra Health plots that trend, tells you when you're running warm or cool for you, and flags shifts worth noticing — in °C or °F, computed locally.
Temperature is one of Oura's most under-read signals. The number on its own (“+0.3”) means little; the trend against your baseline tells the story — the slow rise before you get sick, the dip on a deep-recovery night, the warm run after a hard or boozy day.
What Vitra shows
- Metric
- Nightly skin-temperature deviation from your personal baseline, as recorded by your Oura Ring.
- Trend
- Your deviation plotted over time with a normal-range band, so a notable shift stands out from noise.
- Plain read
- A one-sentence interpretation: running warm, in line, or cooler than usual — with the actual number.
- Units
- Display in °C or °F (a single toggle cascades across the app).
- Early signal
- Sustained upward shifts are surfaced calmly — useful as an early 'maybe ease off' nudge.
- Local
- Computed on your machine. No cloud, no Vitra account.
Context, not alarm
Vitra is deliberately calm about temperature: it shows the trend and a plain reading, not a red siren. A single warm night is usually nothing; a sustained climb above your baseline is the pattern worth seeing. Vitra is not a medical device — for health concerns, talk to a clinician.
Frequently asked
What does Oura body temperature actually measure?
Your Oura Ring measures skin temperature overnight and reports it as a deviation from your personal baseline, not an absolute clinical temperature. A reading of +0.4 means tonight ran 0.4° above your own normal.
Why does Vitra show deviation instead of a number in °C?
Because the signal is the change, not the absolute. Vitra plots your nightly deviation against your rolling baseline so you can see when you're running warm or cool for you — and lets you display it in °C or °F.
Can body temperature flag illness early?
A sustained jump above your baseline often precedes feeling unwell. Vitra surfaces notable upward shifts in plain English so you can ease off before it becomes a lost week — it is not a medical device or a fever thermometer.
Does this need an Oura subscription?
Vitra itself is a one-time purchase with no subscription of its own. It reads temperature through Oura's API, though — and since late 2025 Oura requires an active Oura Membership for API access on Gen 3, Ring 4 and Ring 5 (Gen 2 is exempt). So on those rings you need an active Membership for Vitra to sync. Anything already imported stays on your machine regardless.
