Defining Chronotype in Adolescence The concept of chronotype refers to the innate, biologically determined preference for the timing of sleep and wakefulness within a 24-hour cycle. In the scientific literature, individuals are typically classified along a continuum ranging from morningness (M-type or “larks”), who prefer to wake up and go to sleep early, to eveningness […]
Introduction to Adolescent Sleep Needs Adolescence represents a critical period of intense physical, cognitive, and psychosocial maturation, demanding substantial energetic resources. Central to optimizing these developmental processes is adequate and restorative sleep. While often perceived by adults and teenagers themselves as a mere luxury or a negotiable activity, sleep is biologically mandated for the consolidation […]
Introduction to Adolescent Sleep Physiology Adolescence represents a critical period of physical, cognitive, and emotional development, processes that are profoundly reliant upon adequate and high-quality sleep. Contrary to popular misconception that teenagers simply prefer staying up late, the changes observed in adolescent sleep-wake cycles are primarily driven by fundamental biological shifts. These shifts often place […]
Introduction to Circadian Rhythms in Adolescence The study of adolescent circadian rhythms represents a critical area within developmental psychology and sleep science, highlighting a profound, biologically driven shift in the timing of sleep and wakefulness that occurs universally during the pubertal years. Circadian rhythms are endogenous biological processes that oscillate approximately every 24 hours, regulating […]
Introduction to Adolescent Morning–Evening Preference (Chronotype) The concept of morning–evening preference, formally known as chronotype, refers to the inherent individual differences in the timing of sleep and wakefulness, as well as the peak performance periods throughout the 24-hour cycle. This biological inclination dictates whether an individual is a “lark” (morning type) or an “owl” (evening […]
