Sleep Chronotypes

Meaning

Sleep Chronotypes are genetically determined, individual preferences for the timing of sleep and wakefulness, reflecting variations in the intrinsic period of the individual’s circadian rhythm. These biological preferences categorize individuals, most commonly, as “morning types” (larks), “evening types” (owls), or intermediate types. An individual’s chronotype significantly influences the optimal timing of their hormonal secretion, peak cognitive performance, and metabolic efficiency throughout the 24-hour cycle. Clinical adherence to one’s natural chronotype is crucial for maintaining circadian rhythm integrity and overall metabolic and hormonal health.
