Level 5 - mechanism / opinion, no new human data
Narrative review synthesizing mechanistic and clinical literature without systematic review methodology
PubMed 42074731 · doi:10.3390/jcm15082929
What was done
This comprehensive narrative review synthesized literature on thermoregulatory mechanisms—specifically core body temperature rhythms, the distal-proximal temperature gradient, and melatonin secretion—across sleep disorders including ADHD, insomnia, narcolepsy, obstructive sleep apnea, depression, and restless legs syndrome. It also examined temperature-based interventions such as foot baths, passive body heating, whole-body hyperthermia, and ambient room temperature adjustments.
What was found
The abstract provides no quantitative data or effect sizes. It qualitatively describes how delayed or disrupted core body temperature minima, impaired distal-proximal gradients, and altered melatonin secretion contribute to prolonged sleep latency, fragmented sleep, and daytime dysfunction. Temperature-based interventions were reported to show potential for symptom mitigation and sleep quality improvement.
Why it matters
The review outlines how thermal biology intersects with sleep architecture, highlighting noninvasive thermal interventions as potential personalized therapies for diverse sleep disorders.
Limits
As a narrative review, it lacks a systematic search protocol, quantitative meta-analysis, and risk-of-bias grading. The abstract provides no sample sizes, study counts, or quantitative metrics.

- context Falling asleep and maintaining deep sleep requires core body temperature to decrease by approximately 1 to 3 degrees, while waking energized requires a 1 to 3 degree temperature increase.
