Poor sleep is common in this setting, can persist beyond acute critical illness, and is associated with increased morbidity and mortality. In the past 5\u2009years, intensive care clinical practice guidelines have directed more focus on sleep and circadian disruption, spurring new initiatives to study and improve sleep complications in the critically ill. The global SARS-COV-2 (COVID-19) pandemic and dramatic spikes in patients requiring ICU level care also brought augmented levels of sleep disruption, the understanding of which continues to evolve. This review aims to summarize existing literature on sleep and critical illness and briefly discuss future directions in the field.<\/jats:p>","DOI":"10.3389\/fmed.2023.1199685","type":"journal-article","created":{"date-parts":[[2023,9,20]],"date-time":"2023-09-20T00:36:25Z","timestamp":1695170185000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":18,"title":["Sleep and critical illness: a review"],"prefix":"10.3389","volume":"10","author":[{"given":"Erin","family":"Eschbach","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,9,19]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"585","DOI":"10.1093\/sleep\/33.5.585","article-title":"Sleep duration and all-cause mortality: a systematic review and meta-analysis of prospective studies","volume":"33","author":"Cappuccio","year":"2010","journal-title":"Sleep"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"1450","DOI":"10.1164\/rccm.201504-0767ST","article-title":"An official American Thoracic Society statement: the importance of healthy sleep.
