Im Schlaf ist der sogenannte Sympathikotonus geringer als am Tag, somit sind auch Gegenspieler des Insulins nachts in geringerer Konzentration me\u00c3\u0178bar. Es ergibt sich daher die Frage, ob kurzer Schlaf das Risiko f\u00c3\u00bcr eine Zuckerkrankheit erh\u00c3\u00b6ht.<\/p>\n
Es wurden 21 gesunde Personen \u00c3\u00bcber insgesamt 39 Tage untersucht, im Schlaflabor, in Einzelzimmern, ohne Kenntnis der jeweiligen Tageszeit. \u00c3\u0153ber 5 Tage mussten sie 16 Stunden pro Tag im Bett verbringen, Schlafdauer nach Bedarf. In den folgenden 3 Wochen Schlafdauer maximal 5,6 Std\/24 Stunden, wobei aber die Tage 28 Stunden dauerten (Verschiebung des Circadianrhythmus). \u00c3\u0153ber weitere 9 Tage durfte wieder bis zu 10 Stunden pro Tag geschlafen werden.<\/p>\n
Schlafmangel und St\u00c3\u00b6rung des Circadianrhythmus beeintr\u00c3\u00a4chtigte die Insulinaussch\u00c3\u00bcttung, sie verminderte sich um etwa 12% (basal und postprandial(nach dem Essen)), die Blutzuckerspiegel waren erh\u00c3\u00b6ht. Damit w\u00c3\u00a4re langfristig eine Gewichtszunahme zu erwarten, in diesen F\u00c3\u00a4llen um etwa 4,5 kg in einem Jahr. In der 9-t\u00c3\u00a4gigen “Erholungsphase” normalisierten sich die Stoffwechselver\u00c3\u00a4nderungen.<\/p>\n
