Chronotype: what role in the context of gastroenteropancreatic neuroendocrine tumors?

Journal of Translational Medicine, 2021
Background Chronotype is defined as a trait determining the subject circadian preference in behavioral and biological rhythms relative to external light–dark cycle. Although individual differences in chronotype have been associated with an increased risk

The Chronotype of Elite Athletes [PDF]

Journal of Human Kinetics, 2016
Abstract The aims of this study were (i) to compare the chronotype distribution of elite athletes to a young adult population and (ii) to determine if there was a tendency for athletes to select and/or participate in sports which suited their chronotype. A total of 114 elite athletes from five sports (cricket, cycling, hockey, soccer and

Latitudinal cline of chronotype [PDF]

Scientific Reports, 2017
AbstractThe rotation of the Earth around its own axis and around the sun determines the characteristics of the light/dark cycle, the most stable and ancient 24 h temporal cue for all organisms. Due to the tilt in the earth’s axis in relation to the plane of the earth’s orbit around the sun, sunlight reaches the Earth differentially depending on the ...

Chronotype and Psychiatric Disorders [PDF]

Current Sleep Medicine Reports, 2018
Chronotype, reflecting interindividual differences in daily activity patterns and sleep-wake cycles, is intrinsically connected with well-being. Research indicates increased risk of many adverse mental health outcomes for evening-type individuals. Here, we provide an overview of the current evidence available on the relationship between chronotype and ...

The Impact of Sleep Chronotype on Psychological Well-being and its Underlying Neural Mechanisms [PDF]

SHS Web of Conferences, 2023
Biological rhythms have long been a focus of the investigation, and sleep chronotype is one study area. Many studies have shown that the morning-type sleep chronotype is a protective factor for psychological well-being, while the evening-type sleep ...

Chronotype ontogeny related to gender [PDF]

Brazilian Journal of Medical and Biological Research, 2014
Chronotype is an established concept designed to identify distinct phase relationships between the expression of circadian rhythms and external synchronizers in humans. Although it has been widely accepted that chronotype is subjected to ontogenetic modulation, there is no consensus on the interaction between age and gender.

Chronotypes and circadian timing in migraine [PDF]

Cephalalgia, 2017
Background It has been suggested that migraine attacks strike according to circadian patterns and that this might be related to individual chronotype. Here we evaluated and correlated individual chronotypes, stability of the circadian rhythm, and circadian attack timing in a large and well-characterised migraine population.

Eveningness is associated with sedentary behavior and increased 10-year risk of cardiovascular disease: the SCAPIS pilot cohort

Scientific Reports, 2022
Chronotype reflects individual preferences for timing activities throughout the day, determined by the circadian system, environment and behavior. The relationship between chronotype, physical activity, and cardiovascular health has not been established.

Effects of undergraduates’ chronotypes and perceived stress on their sleep quality: A cross-sectional study

European Psychiatry, 2023
Introduction Undergraduate students encounter developmental challenges during their transition into adulthood. Previous studies have claimed that adults with later chronotypes usually manifest negative psychological effects: poor sleep quality, greater ...

Chronotype, gender, and time for sex [PDF]

Chronobiology International, 2014
The study aimed at testing chronotype and gender differences in the time of day when humans feel the greatest need for sex and the time of day they actually undertake sexual activity. A Polish sample of 565 participants aged between 18 and 57 was tested.
