Chronotype

Topic

A chronotype is the behavioral manifestation of an individual's underlying circadian rhythm, dictating their natural propensity to sleep and feel alert at specific times during a 24-hour period. It is commonly characterized by the spectrum of morningness (being most active early in the day) and eveningness (being most active late in the day). While genetics and age heavily influence a person's chronotype, most individuals fall somewhere between these two extremes with some flexibility in their sleep schedules.
