The Association Between Circadian Disruption in Core Body Temperature Rhythm and Post‐Chemotherapy Sleep Disturbances in Breast Cancer Survivors

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep disturbance is a common symptom experienced by approximately 70% of breast cancer survivors and persists after the conclusion of chemotherapy. This study aimed to quantify the circadian disruption of the core body temperature (CBT) rhythm and its correlation with sleep disturbance following chemotherapy.

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 Association Between Disordered Eating and Sleep in Non‐Clinical Populations—A Systematic Review and Meta‐Analysis

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep and disordered eating behaviours may be linked through physiological and psychological mechanisms; yet, no review has systematically investigated the relationship between different sleep indicators and disordered eating behaviours and cognitions outside a clinical context.

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.

Temporal Associations of Physical Activity Volume, Intensity, and Timing With Sleep in Preschool‐Aged Children

Journal of Sleep Research, EarlyView.
ABSTRACT This study aimed to investigate the temporal relationships between accelerometer‐derived physical activity metrics—specifically volume, intensity, and timing—with the preceding and subsequent nights' sleep in preschool‐aged children. This analysis used the baseline data from a randomised controlled trial among 93 children (53 boys) aged 3–5.9 ...

Age at Onset and Delays in Diagnosis of Central Disorders of Hypersomnolence Over the Past 30 Years

Journal of Sleep Research, EarlyView.
ABSTRACT Patients with narcolepsy type 1 (NT1), type 2 (NT2), idiopathic hypersomnia (IH) usually suffer from symptoms for years, even decades, before being diagnosed. We aimed to assess age at onset, age at diagnosis and changes in the diagnostic delays of these patients from 1990 to 2020 in a single centre.

Sleep and Rhythmic Profile After Pineal Gland Removal in Humans

Journal of Sleep Research, EarlyView.
ABSTRACT Melatonin, a hormone produced by the pineal gland, is classically described as a central circadian modulator. However, the impact of its absence on circadian rhythmicity in humans remains poorly understood. Pinealectomised patients, in whom melatonin secretion is chronically suppressed, represent a valuable clinical model to investigate the ...

The hidden clock: how chronotype is related to depression, anxiety, and stress in adolescents – insights from the EHDLA study

International Journal of Mental Health Systems
Background Depression, anxiety, and stress symptoms are common among adolescents; however, studies exploring their relationship with chronotype in European youth populations is scarce.
