Circulating Rhythmic Metabolites and Causal Risk of Type 2 Diabetes in Adults in the Canadian Longitudinal Study on Aging

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Circadian regulation of metabolism is an important factor in metabolic health, yet the role of rhythmic metabolites in Type 2 diabetes development remains poorly understood. This study investigated associations between circulating rhythmic metabolites and incident Type 2 diabetes risk and evaluated causal relationships using two‐sample ...

From ZZZ\u27s to A\u27s: How Your Sleep Cycle Affects How You Study [PDF]

, 2017
Studying and sleeping are two essential parts of succeeding in an academic setting. The expression “the early bird gets the worm” suggests that people who wake up early garner more success in life. But why?

Sleep Efficiency Predicts Next‐Day Glycaemia and Daytime Glycaemia Influences Sleep in Free‐Living Adults at Risk of Type 2 Diabetes

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aim To investigate how sleep features influence next‐day diurnal glucose homeostasis and vice versa in free‐living adults at risk of type 2 diabetes. Materials and Methods This observational repeated‐measures study included 388 adults aged 25–65 years (50% women) with overweight or obesity (BMI ≥ 25.0–< 40.0 kg/m2).

The linkage between chronotype, social jetlag, and responses to sleep inertia

Scientific Reports
This research explores the interplay between chronotype, sleep inertia (SI), and social jetlag (SJL), examining whether an interaction between chronotype and SJL increases susceptibility to SI in individuals with an evening chronotype, due to their more ...

Chronotype, social jetlag, and time perspective [PDF]

Chronobiology International, 2019
The phase of entrainment (chronotype) is known to be associated with time perspective (TP), suggesting that the state of circadian system is involved in the long-term planning of human life. However, little is known regarding the influence of circadian misalignment on long-term planning ability.

The Ecology of Human Sleep (EcoSleep) Cohort Study: Protocol for a longitudinal repeated measurement burst design study to assess the relationship between sleep determinants and outcomes under real‐world conditions across time of year

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The interplay of daily life factors, including mood, physical activity, or light exposure, influences sleep architecture and quality. Laboratory‐based studies often isolate these determinants to establish causality, thereby sacrificing ecological validity.

Circadian rhythms and second language performance [PDF]

, 2017
Human behavior is not constant over the hours of the day, and there are considerable individual differences. Some people raise early and go to bed early and have their peek performance early in the day (“larks”) while others tend to go to bed late and ...

Human Chronotypes from a Theoretical Perspective

PLoS ONE, 2013
The endogenous circadian timing system has evolved to synchronize an organism to periodically recurring environmental conditions. Those external time cues are called Zeitgebers. When entrained by a Zeitgeber, the intrinsic oscillator adopts a fixed phase relation ψ to the Zeitgeber.

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.

Chronotype in relation to shift work: A cohort study among 37,731 female nurses

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Chronotype may affect tolerance for circadian disruption induced by shift work. This study examines the association between chronotype, self‐reported sleep timing, shift type preference, and sleep problems among nurses, and studies chronotype stability over time.
