Although efforts have been made to elucidate the aetiological factors involved in the illness, little progress has been made in uncovering what contributes to the development and maintenance of anorexia nervosa. A particular shortcoming of the current literature has been the investigation of interactions between environmental and biological factors. One such interaction which has yet to receive attention in anorexia nervosa is that of sun exposure. Exposure to the sun\u2014including levels of ultraviolet radiation (UVR) and vitamin D\u2014in the pathogenesis of other mental illnesses has long been investigated (with lower levels of vitamin D reportedly involved in the pathogenesis of conditions such as schizophrenia, for example) but is yet to be explored in anorexia nervosa.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The current paper proposes a novel hypothesis for the potential contribution of reduced sun exposure in the aetiology of anorexia nervosa for future investigation, and possible mechanisms for how this relationship may operate.<\/jats:p><\/jats:sec>","DOI":"10.1111\/eip.70054","type":"journal-article","created":{"date-parts":[[2025,5,28]],"date-time":"2025-05-28T03:29:37Z","timestamp":1748402977000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Sun Exposure and Anorexia Nervosa: A Potential Environmental\u2013Biological Interaction?"],"prefix":"10.1111","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1009-6619","authenticated-orcid":false,"given":"Andrea","family":"Phillipou","sequence":"first","affiliation":[{"name":"Orygen  Melbourne Australia"},{"name":"Centre for Youth Mental Health The University of Melbourne  Melbourne Australia"},{"name":"Orygen Specialist Program, Royal Melbourne Hospital  Melbourne Australia"},{"name":"Department of Psychological Sciences Swinburne University of Technology  Melbourne Australia"},{"name":"Department of Mental Health St Vincent's Hospital  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,5,27]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425787"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140\u20106736(00)48619\u20108"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.20884"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41380-021-01025-0"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/oby.2011.404"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.nmd.0000243922.49394.7d"},{"key":"e_1_2_6_8_1","article-title":"Recovery From Anorexia Nervosa and Bulimia Nervosa at 22\u2010Year Follow\u2010Up","volume":"78","author":"Eddy K.
