Given that several studies in adults have described a \u2018vegetative preparedness to sleep\u2019 (in which distal skin vasodilation before lights\u2010out promotes rapid sleep onset), we looked at whether or not this process operates in preterm neonates. Sleep propensity was assessed in terms of the duration of a spontaneous episode of wakefulness (W). Skin temperatures at six body sites (the abdomen, pectoral region, eye, hand, thigh and foot) were measured (using infrared thermography) during nocturnal polysomnography in 29 9\u2010day\u2010old preterm neonates (postmenstrual age: 209\u00a0\u00b1\u00a09\u00a0days). We then determined whether the duration of the W episode depended upon the local skin temperatures measured at the start, during and end of the episode. The W episode was shorter when distal skin temperatures (thigh, hand and foot) and the pectoral temperature were higher at the end of the episode (i.e. at sleep onset). The relationship with the duration of the W episode was not significant for temperatures measured at the start of the W episode. We observed gradual distal vasodilation at the pectoral region, the thigh, hand and foot (i.e. affecting most of the body's skin surface) during W episodes. Our results constitute initial evidence to show that distal vasodilation may have a key role in facilitating sleep onset in very preterm neonates.<\/jats:p>","DOI":"10.1111\/jsr.12514","type":"journal-article","created":{"date-parts":[[2017,3,17]],"date-time":"2017-03-17T05:47:09Z","timestamp":1489729629000},"page":"572-577","source":"Crossref","is-referenced-by-count":15,"title":["Distal skin vasodilation promotes rapid sleep onset in preterm neonates"],"prefix":"10.1111","volume":"26","author":[{"given":"Lucile","family":"Barcat","sequence":"first","affiliation":[{"name":"P\u00e9riTox Jules Verne University of Picardy Amiens France"},{"name":"M\u00e9decine N\u00e9onatale et R\u00e9animation P\u00e9diatrique P\u00f4le Femme Couple Enfant Amiens France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pauline","family":"Decima","sequence":"additional","affiliation":[{"name":"P\u00e9riTox Jules Verne University of Picardy Amiens France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emilie","family":"Bodin","sequence":"additional","affiliation":[{"name":"P\u00e9riTox Jules Verne University of Picardy Amiens France"},{"name":"Neurologie P\u00e9diatrique P\u00f4le Femme Couple Enfant Amiens France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephane","family":"Delanaud","sequence":"additional","affiliation":[{"name":"P\u00e9riTox Jules Verne University of Picardy Amiens France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erwan","family":"Stephan\u2010Blanchard","sequence":"additional","affiliation":[{"name":"P\u00e9riTox Jules Verne University of Picardy Amiens France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andre","family":"Leke","sequence":"additional","affiliation":[{"name":"P\u00e9riTox Jules Verne University of Picardy Amiens France"},{"name":"M\u00e9decine N\u00e9onatale et R\u00e9animation P\u00e9diatrique P\u00f4le Femme Couple Enfant Amiens France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean\u2010Pierre","family":"Libert","sequence":"additional","affiliation":[{"name":"P\u00e9riTox Jules Verne University of Picardy Amiens France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre","family":"Tourneux","sequence":"additional","affiliation":[{"name":"P\u00e9riTox Jules Verne University of Picardy Amiens France"},{"name":"M\u00e9decine N\u00e9onatale et R\u00e9animation P\u00e9diatrique P\u00f4le Femme Couple Enfant Amiens France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0684-0305","authenticated-orcid":false,"given":"Veronique","family":"Bach","sequence":"additional","affiliation":[{"name":"P\u00e9riTox Jules Verne University of Picardy Amiens France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,3,17]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"404","article-title":"Die Extremit\u00e4ten als Effektoren der physikalischen Temperaturregulation","volume":"108","author":"Aschoff J.","year":"1958","journal-title":"Wiener.
