Employing the Apple Watch for data collection, REM sleep duration and frequency were monitored over a specified period. Concurrently, participants\u2019 depressive symptoms were evaluated using standardized questionnaires. The analysis, primarily using Spearman\u2019s correlation, revealed noteworthy findings. A significant correlation was observed between an increased REM sleep proportion and higher depressive symptom scores, with a correlation coefficient of 0.702, suggesting a robust relationship. These results highlight the potential of using wearable technology, such as the Apple Watch, in early detection and intervention for depressive symptoms, suggesting that alterations in REM sleep could serve as preliminary indicators of depressive tendencies. This approach offers a non-invasive and accessible means to monitor and potentially preempt the progression of depressive disorders. This study\u2019s implications extend to the broader context of mental health, emphasizing the importance of sleep assessment in routine health evaluations, particularly for individuals exhibiting early signs of depressive symptoms.<\/jats:p>","DOI":"10.3390\/jpm14050519","type":"journal-article","created":{"date-parts":[[2024,5,14]],"date-time":"2024-05-14T08:03:08Z","timestamp":1715673788000},"page":"519","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Deciphering the Link: Correlating REM Sleep Patterns with Depressive Symptoms via Consumer Wearable Technology"],"prefix":"10.3390","volume":"14","author":[{"given":"C\u0103t\u0103lina Angela","family":"Cri\u0219an","sequence":"first","affiliation":[{"name":"Department of Neurosciences, Psychiatry and Pediatric Psychiatry, Faculty of Medicine, Iuliu Ha\u021bieganu University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9433-3118","authenticated-orcid":false,"given":"Roland","family":"Stretea","sequence":"additional","affiliation":[{"name":"Clinical Hospital of Infectious Diseases, 400348 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1853-4425","authenticated-orcid":false,"given":"Maria","family":"Bonea","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, Psychiatry and Pediatric Psychiatry, Faculty of Medicine, Iuliu Ha\u021bieganu University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vadim","family":"F\u00eent\u00eenari","sequence":"additional","affiliation":[{"name":"SC STEEPSOFT AI SRL, 505600 Sacele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ioan Marian","family":"\u021aa\u021ba","sequence":"additional","affiliation":[{"name":"Automatics and Computers Doctoral School, Politehnica University of Bucharest, 060042 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandru","family":"Stan","sequence":"additional","affiliation":[{"name":"Clinical Emergency Hospital for Children, 400370 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ioana Valentina","family":"Miclu\u021bia","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, Psychiatry and Pediatric Psychiatry, Faculty of Medicine, Iuliu Ha\u021bieganu University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R\u0103zvan Mircea","family":"Chereche\u0219","sequence":"additional","affiliation":[{"name":"Department of Public Health, College of Political, Administrative and Communication Sciences, Babe\u0219-Bolyai University, 400294 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1898-3685","authenticated-orcid":false,"given":"Zaki","family":"Milhem","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, Psychiatry and Pediatric Psychiatry, Faculty of Medicine, Iuliu Ha\u021bieganu University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"615","DOI":"10.1016\/j.psc.2015.07.002","article-title":"The Neurobiology of Sleep and Wakefulness","volume":"38","author":"Schwartz","year":"2015","journal-title":"Psychiatr.
