Aging is linked to sleep timing through a circadian phase advance that causes earlier sleep onset and awakening [1]. This shift is driven by biological changes in the circadian rhythm, such as altered melatonin and cortisol secretion patterns [2], resulting in an average advancement of sleep timing by approximately one hour [3].

claimAdjustments in sleep-wake timings during aging are associated with a circadian phase advance, which is characterized by an earlier onset of evening sleepiness and earlier morning awakening.
claimThe earlier shift in sleep timing during aging is believed to mirror biological alterations in the circadian rhythm, including an overall decline in melatonin levels, earlier melatonin release, an advance in cortisol secretion, and a diminished range of core body temperature fluctuation throughout the day.
measurementThe earlier shift in sleep timing observed in aging individuals amounts to approximately one hour on average.
