Description
Temperature Deviation is a smart metric showing how your overnight skin/body temperature changes relative to your personal baseline (rather than a single absolute thermometer reading). Many wearables report deviation because it’s more robust than absolute temperature across devices and environments.
Why it matters
A positive deviation (warmer than baseline) can reflect early illness, inflammation, alcohol, late intense exercise, or a warmer sleep environment. In females, temperature deviation can also shift with the menstrual cycle (post‑ovulation/luteal phase tends to run higher).
How to interpret it (practical)
Focus on multi-night trends.
Compare alongside respiratory rate, resting heart rate, HRV, and sleep quality.
If deviation is elevated and other recovery metrics worsen, consider it a “take it easier” signal.
Common sources of noise
Room temperature, heavy blankets, late hot showers/saunas, alcohol, and device placement can influence readings. Consistent sleep conditions improve signal quality.
