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 Chronotype The concept of chronotype refers to an individual’s intrinsic preference for sleeping and waking at a particular time, fundamentally dictated by their internal biological clock, the circadian rhythm. While chronotypes exist on a spectrum ranging from “morning larks” (early types) to “night owls” (evening types), adolescence marks a critical developmental period […]
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 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 […]
