We conducted a longitudinal cohort study measuring bedroom air temperature and humidity over three non-consecutive weeks (N = 19 participants; 409 observation nights) using HOBO loggers and sleep health using wrist-actigraphy and sleep diaries. Outdoor temperature and humidity were obtained from a nearby weather station. Linear mixed-effects regression models assessed relationships between temperature and sleep health metrics. Nighttime indoor apparent temperature ranged from 26 to 35 \u00b0C and averaged 5 \u00b0C higher than outdoors. On average, participants slept 6.7 h per night with 83% sleep efficiency. After adjustment, a 5 \u00b0C increase in indoor nighttime dry bulb temperature was associated with a 23 min reduction in mean total sleep time (\u03b2 = \u221223.30 [\u221243.30, \u22123.45]) and mean onset latency increase of approximately 2 min (\u03b2 = 1.85 [0.50, 6.65]). Nighttime heat waves were associated with a 4% reduction in mean sleep efficiency (\u03b2 = \u22123.71 [\u22126.83, \u22120.66]) and an 11 min increase in onset latency (\u03b2 = 11.32 [2.60, 20.75]). We found evidence that rising summertime temperatures reduced sleep health in a disproportionately impacted community, suggesting that climate change will worsen existing sleep health disparities.<\/jats:p>","DOI":"10.3390\/ijerph22091391","type":"journal-article","created":{"date-parts":[[2025,9,8]],"date-time":"2025-09-08T08:06:32Z","timestamp":1757318792000},"page":"1391","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Ambient and Bedroom Heat in Relation to Sleep Health in a Marginalized Community That Is One of the Hottest in Los Angeles"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0403-0410","authenticated-orcid":false,"given":"Hasibe","family":"Caballero-Gomez","sequence":"first","affiliation":[{"name":"Department of Environmental Health Sciences, Fielding School of Public Health, University of California, Los Angeles, CA 90095, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jill","family":"Johnston","sequence":"additional","affiliation":[{"name":"Department of Environmental and Occupational Health, University of California, Irvine, Irvine, CA 92697, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0915-8272","authenticated-orcid":false,"given":"Chandra L.","family":"Jackson","sequence":"additional","affiliation":[{"name":"Epidemiology Branch, National Institute of Environmental Health Sciences, National Institutes of Health, Department of Health and Human Services, Research Triangle Park, NC 27709, USA"},{"name":"Intramural Research Program, National Institute on Minority Health and Health Disparities, National Institutes of Health, Department of Health and Human Services, Bethesda, MD 20892, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lizette","family":"Romano","sequence":"additional","affiliation":[{"name":"Department of Environmental Health Sciences, Fielding School of Public Health, University of California, Los Angeles, CA 90095, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0640-6450","authenticated-orcid":false,"given":"Lara J.","family":"Cushing","sequence":"additional","affiliation":[{"name":"Department of Environmental Health Sciences, Fielding School of Public Health, University of California, Los Angeles, CA 90095, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,6]]},"reference":[{"key":"ref_1","unstructured":"Colten, H.R., Altevogt, B.M., and Institute of Medicine (U.S.) (2006).
