The endogenous melatonin onset in dim light (DLMO) is a marker of circadian phase that can be used to appropriately time the administration of bright light or exogenous melatonin in order to elicit a desired phase shift. Determining an individual's circadian phase can be costly and time-consuming. We examined the relationship between the DLMO and sleep limes in 16 young healthy individuals who slept at their habitual limes for a week. The DLMO occurred about 2 hours before bedtime and 14 hours after wake. Wake time and midpoint of sleep were significantly associated with the DLMO ( r = 0.77, r= 0.68 respectively), but bedtime was not (r= 0.36). The possibility of predicting young healthy normally entrained people's DLMOs from their sleep times is discussed. [ABSTRACT FROM AUTHOR] |
