Dietary and lifestyle behaviors are increasingly recognized as key determinants of sleep quality. Women are particularly susceptible to sleep disturbances due to hormonal fluctuations and psychosocial factors. However, women remain underrepresented in sleep research. This study aims to examine the associations between sleep quality, nutrition, and lifestyle in a large cohort of Spanish women. Methods: A cross-sectional study was conducted with 785 women aged 18\u201364. Participants completed the Pittsburgh Sleep Quality Index (PSQI) and the NutSo-HH questionnaire on dietary and lifestyle behaviors. Descriptive analyses, correlation matrices, Gaussian Graphical Models, and Principal Component Analyses were used to assess relationships between variables. Results: More than half of the participants rated their sleep quality as good or very good, although over 30% experienced frequent nighttime awakenings. Poor sleep quality was significantly associated with higher alcohol consumption, lower vegetable and white fish intake, and lower levels of physical activity. Diets rich in ultra-processed foods correlated moderately with subjective poor sleep and daytime dysfunction. However, no strong associations were found between stimulant consumption, late meals, or dietary patterns (e.g., Mediterranean diet) and sleep. Self-perceived health emerged as a protective factor, while nocturnal lifestyles were linked to longer sleep latency and fragmented sleep. Conclusions: In adult women, better sleep quality is linked to healthy dietary choices, regular physical activity, and a positive perception of general health. In contrast, alcohol use and irregular lifestyles are associated with poor sleep. Individual variability and cultural adaptation may moderate the impact of some traditionally harmful behaviors. Personalized, multidimensional interventions are recommended for promoting sleep health in women.<\/jats:p>","DOI":"10.3390\/nu17132225","type":"journal-article","created":{"date-parts":[[2025,7,4]],"date-time":"2025-07-04T11:20:11Z","timestamp":1751628011000},"page":"2225","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Nutritional and Lifestyle Behaviors and Their Influence on Sleep Quality Among Spanish Adult Women"],"prefix":"10.3390","volume":"17","author":[{"given":"Andr\u00e9s Vicente","family":"Mar\u00edn Ferrandis","sequence":"first","affiliation":[{"name":"Faculty of Medicine and Health Sciences, Catholic University of Valencia San Vicente M\u00e1rtir, c\/Quevedo, 2, 46001 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agnese","family":"Broccolo","sequence":"additional","affiliation":[{"name":"Department of Biomedicine and Prevention, Tor Vergata University, Via Montpellier, 00133 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5998-476X","authenticated-orcid":false,"given":"Michela","family":"Piredda","sequence":"additional","affiliation":[{"name":"Research Unit of Nursing Science, Department of Medicine and Surgery, Campus Bio-Medico di Roma University, Via Alvaro del Portillo, 21, 00128 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valentina","family":"Micheluzzi","sequence":"additional","affiliation":[{"name":"Department of Biomedicine and Prevention, Tor Vergata University, Via Montpellier, 00133 Rome, Italy"},{"name":"Clinical and Interventional Cardiology, Sassari University Hospital, 07100 Sassari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5770-0719","authenticated-orcid":false,"given":"Elena","family":"Sandri","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Sciences, Catholic University of Valencia San Vicente M\u00e1rtir, c\/Quevedo, 2, 46001 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"56048","DOI":"10.12775\/JEHS.2024.75.56048","article-title":"Sleep Quality and Immune Function: Implications for Overall Health\u2014A Literature Review","volume":"75","author":"Sitarek","year":"2024","journal-title":"J.
