Influence of Chronotype on Cycling Performance in Simulated 20‐km Time Trials—A Pilot Study

Journal of Sleep Research, EarlyView.
Evening‐type athletes show improved cycling performance later in the day, whilst morning types peak earlier. These differences appear linked to variations in mental readiness and sleepiness, highlighting the importance of considering chronotype in performance planning.

Acute Effects of Sleep Extension on Fatigue, Inhibitory Control, Short‐Term Vigilance and Neuromuscular Function in Youth Elite Ice Hockey Players: A Randomised Crossover Trial

Journal of Sleep Research, EarlyView.
Scheduling a 10‐h sleep opportunity (sleep extension) in elite youth athletes increased total sleep time by approximately 1 h compared to normal sleep. Cognitive performance on an inhibitory control task (20‐min colour multisource interference task; cMSIT) improved after sleep extension, and this was accompanied by an overall lower perception of ...

Increased p‐Tau181 Levels After Overnight Wakefulness Are Associated With Neuroticism in Young Women

Journal of Sleep Research, EarlyView.
Overnight wakefulness, mimicking night shift conditions, impaired morning vigilance in healthy, reproductive‐aged women, regardless of estradiol or neuroticism. However, the overnight wakefulness‐related rise in the Alzheimer's disease blood biomarker p‐Tau181 was greater in women with higher neuroticism, suggesting that neurobiological vulnerability ...

Delta‐9‐Tetrahydrocannabinol (THC) Before Bedtime: Feasibility and Mechanistic Pilot Study on Sleep and Cardiac Autonomic Activity

Journal of Sleep Research, EarlyView.
ABSTRACT Disordered sleep is a common reason individuals report using cannabis, yet the physiological effects of Δ9‐tetrahydrocannabinol (Δ9‐THC) on sleep and autonomic regulation remain incompletely understood. Early studies reported acute sleep‐promoting effects of Δ9‐THC, but chronic use has been associated with disrupted sleep and possible ...

Rest Assured: The Association of Structural, Functional Support, and Loneliness With Subjective Sleep Health

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep is increasingly understood as a socially embedded phenomenon. This study examined how structural and functional aspects of social support, as well as loneliness, relate to sleep health in a German sample of middle‐aged adults (N = 5388).
