Chronic insomnia can be caused by a number of different problems, including medical conditions, mental-health problems, medication side effects, or substance abuse. Association between puberty and delayed phase preference. The phase-delay portion of the PRC has greater amplitude in the P49 pubertal mice. Comp Biochem Physiol [A] ; The Developmental Changes Driving Adolescent Sleep Patterns A number of studies provide strong support that the homeostatic and circadian regulation of sleep are sensitive to gonadal hormones. The reason for this difference in developmental timing is unclear, but a role for artificial lighting in prolonging delayed phase in human adolescents is a possibility.

How Much Sleep Do I Need?
In other cultures, similar developmental timing is observed, although the peak delay may occur as early as 15—16 years of age [ 123456 ]. This is problematic because, for animals living in laboratories, lighting conditions during a circadian experiment can mimic seasonal changes in day length and alter pubertal progression [ 31 ]. These mechanisms are illustrated using a PRC depicting the circadian phase response of male degus to a light pulse presented at different times of the day. Homeostatic sleep regulation in adolescents. Quantitative histological changes in the hypothalamic nuclei in the prepuberal, puberal, and postpuberal female rat.
