Abstract

Correlations between altered body temperature and depression have been reported in small samples; greater confidence in these associations would provide a rationale for further examining potential mechanisms of depression related to body temperature regulation. We sought to test the hypotheses that greater depression symptom severity is associated with (1) higher body temperature, (2) smaller differences between body temperature when awake versus asleep, and (3) lower diurnal body temperature amplitude. Data collected included both self-reported body temperature (using standard thermometers), wearable sensor-assessed distal body temperature (using an off-the-shelf wearable sensor that collected minute-level physiological data), and self-reported depressive symptoms from > 20,000 participants over the course of ~ 7 months as part of the TemPredict Study. Higher self-reported and wearable sensor-assessed body temperatures when awake were associated with greater depression symptom severity. Lower diurnal body temperature amplitude, computed using wearable sensor-assessed distal body temperature data, tended to be associated with greater depression symptom severity, though this association did not achieve statistical significance. These findings, drawn from a large sample, replicate and expand upon prior data pointing to body temperature alterations as potentially relevant factors in depression etiology and may hold implications for development of novel approaches to the treatment of major depressive disorder.

  • Diurnal amplitude in distal body temperature measured by an Oura Ring is associated with depression.

    “Diurnal amplitude in distal body temperature measured by an Oura Ring was associated with depression39, possibly due to its sensitivity to thermoregulatory dysregulation.”

    From Sleep and temperature data from wearable devices support noninvasive detection of diabetes mellitus in a large-scale, retrospective analysis (2026) · cites this paper as [39]

    The Methods identify the Oura Ring as the device measuring distal body temperature, and the Results report that diurnal amplitude generally decreased as depressive symptom severity increased. However, the Abstract says the overall association only tended in that direction and did not reach statistical significance. The unqualified claim that amplitude “was associated” omits that important caveat. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Neither prior literature was able to test their efficacy in large, real-world cohorts representing a practical assessment.

    “Though interesting, neither literature was able to test their efficacy in large, real-world cohorts representing a practical assessment.”

    From Sleep and temperature data from wearable devices support noninvasive detection of diabetes mellitus in a large-scale, retrospective analysis (2026) · cites this paper as [39]

    The Introduction says prior studies of body temperature and depressive symptoms had fewer than 300 participants and were conducted in controlled settings; the Discussion says this study examined the association in a larger sample outside the laboratory. That supports the claim about a gap in large, real-world assessments, but the paper does not say those earlier studies tested efficacy, and it describes its own work as observational rather than an efficacy test. No page numbers are available in our copy. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
