The circadian rhythm is crucial for physiological and behavioral functions. Chronotype,
which represents individual preferences for activity and performance, is associated with …

The interest in the systematic study of the circadian typology (CT) is relatively recent and has
developed rapidly in the two last decades. All the existing data suggest that this individual …

Several studies have shown the differences among chronotypes in the circadian rhythm of
different physiological variables. Individuals show variation in their preference for the daily …

Chronotype can be defined as an expression or proxy for circadian rhythms of varied
mechanisms, for example in body temperature, cortisol secretion, cognitive functions, eating …

Evening-oriented sleep timing preferences have been associated with risk of diabetes,
cardiovascular diseases, obesity, psychiatric disorders, and increased mortality. This …

A marked individual difference is the morningness–eveningness preference or chronotype.
Presenting its high relevance in predicting human behavior, we stress the need to control for …

The study investigates the effect of the month of birth and ambient light conditions at birth on
sleep length and chronotype among residents of high latitudes. The authors surveyed 1172 …

Circadian rhythms refer to biological rhythms that have an endogenous period length of
approximately 24 hr. However, not much is known about the variance in the development of …

The present study aimed to investigate the possible role played by environmental
temperature in modulating circadian preference, collecting data in Italy and India. We chose …

Individuals differ in their circadian preferences (chronotype). There is evidence in the
literature to support a season-of-birth effect on chronotype but the evidence is not …
