TL;DR
Investigating ‘chronotypes' observed an abrupt change in the timing of sleep at around the age of 20 and propose this change as the first biological marker of the end of adolescence.
Abstract
Between childhood and adulthood, we go through puberty and adolescence. While the end of puberty is defined as the point of cessation of bone growth (epiphyseal closure; girls: 16 y; boys: 17.5 y), the end of adolescence (∼19 y) is defined less clearly, by a mixture of physical, psychological, social, and mental measures [1]. One conspicuous property of adolescence is the apparently unsaturable capacity to stay up late and to sleep in. Investigating ‘chronotypes’ we observed an abrupt change in the timing of sleep at around the age of 20 and propose this change as the first biological marker of the end of adolescence.

It is predicted that the timing of sleep has changed during industrialization and that a majority of humans are sleep deprived during the workweek, and the implications are far ranging concerning learning, memory, vigilance, performance, and quality of life.

A variant in human sleep behavior can be attributed to a missense mutation in a clock component, hPER2, which alters the circadian period.

In men, age-related changes in slow wave sleep and REM sleep occur with markedly different chronologies and are each associated with specific hormonal alterations.

The length of the Per3 repeat region identifies a potential genetic marker for extreme diurnal preference and was strongly associated with the delayed sleep phase syndrome patients, 75% of whom were homozygous.

The aim of this study was to analyze gender difference in morningness–eveningness preference using the Horne and Östberg questionnaire in the largest university student population selected so far.

444 Citations2001Jeanne F. Duffy, David W. Rimmer +1 more
A chronobiological mechanism by which the biological clock of morning types may be set to an earlier hour is explored, demonstrating that a fundamental property of the circadian pacemaker is correlated with the behavioral trait of morningness-eveningness.

Understanding entrainment is equal to understanding the circadian system and the results of this basic research will help to understand temporal ecology and will allow to improve conditions for humans in industrialized societies.

360 Citations2000Derk‐Jan Dijk, Jeanne F. Duffy +1 more
The internal circadian phase advance of awakening, as well as the age-related reduction in sleep consolidation, appears related to an age- related reduction in the promotion of sleep by the circadian pacemaker during the biological night in combination with a reduced homeostatic pressure for sleep.

Two groups of subjects were selected and monitored during entrained, habitual sleep-wake conditions and during 24 h of controlled wakefulness in a laboratory-based constant-routine procedure, and evidence is provided for the endogenous nature of morningness-eveningness.

The morningness-eveningness preference identified by the MEQ score refers to 2 distinct mechanisms, 1 associated with a difference in circadian period and phase of entrainment and the other associated with chronobiological aspects of sleep regulation.

Results provide further evidence that the interaction between the circadian system and sleep-wake timing is altered in aging, and suggest that a shortening of circadian period with age cannot account for the advanced circadian phase and earlier wake times of older subjects.

This review summarizes the current knowledge on changes of the circadian system in advanced age, mainly for rodents, and the possibility exists to treat age-dependent disturbances, which includes oscillator(s), mechanisms of external synchronization and of internal coupling.
SLEEPThe Transition of Sleep-Wake Patterns in Early Adolescence
179 Citations2003Susan Shur‐Fen Gau, Wei‐Tsuen Soong
The hypothesis that school grade level is significantly associated with the transition to evening type in early adolescence is supported and environmental factors may play a more important role than biologic factors, such as age, sex, and pubertal development, in the transition from morning type to Evening type at early adolescence.

This introduction to the special issue of Chronobiology International first briefly addresses the impact of disturbed sleep in the elderly to show that the development of therapeutic methods other than the currently available pharmacological treatments should be given high priority.

Determining the physiological basis for age related changes in the responsiveness of the clock to both internal and external stimuli, and the mechanisms by which normal circadian function can be restored, should lead to new insight into the functioning of the circadian clock and may lead into new approaches for normalizing disturbed circadian rhythms.
