Editorial Research · Sleep Science
The GetClariSync Sleep Desk reviews peer-reviewed research in sleep science, chronobiology, and circadian medicine. We focus on journals indexed in PubMed — including Sleep, Sleep Medicine Reviews, Nature Communications, the Journal of Sleep Research, and the Journal of Clinical Sleep Medicine. Each article cites its primary sources, distinguishes correlational findings from causal evidence, and is reviewed for accuracy before publication. We update articles when stronger evidence emerges and post a correction note when we change a substantive claim. We are editorial researchers, not clinicians — for medical concerns, sleep disorders, or persistent insomnia please consult a board-certified sleep physician or your primary care provider.
