The impact of long-haul travel and 13 h time change on sleep and rest activity circadian rhythm in speed skaters during World Cup competitions.

Athletes frequently compete only a few days after long-haul travel. Longitudinal real-world data on athletes' sleep and sleep-wake cycle in competitive settings remain scarce. This study assessed the impact of a long-haul travel across ∼13 time zones on sleep patterns, rest-activity circadian rhythms (RAR), and their subsequent effects on neuromuscular function and race performance in the Canadian Short-Track Speed Skating Team.

Cold operational readiness in the military: from science to practice.

Cold weather operations are logistically difficult to orchestrate and extremely challenging for soldiers. Decades of research and empirical evidence indicate that humans are extremely vulnerable to cold and that individual responses are highly variable. In this context, it may be necessary to develop personalised strategies to sustain soldiers' performance and ensure overall mission success in the cold.

Household and housing determinants of sleep duration during the COVID-19 pandemic: Results from the COHESION Study.

Background: Public health measures in response to the COVID-19 pandemic forced individuals to spend more time at home. We sought to investigate the relationship between housing characteristics and sleep duration in the context of COVID-19.

Methods: Our exploratory study was part of the COvid-19: Health and Social Inequities across Neighborhoods (COHESION) Study Phase-1, a pan-Canadian population-based cohort involving nearly 1300 participants, launched in May 2020.

Negative health outcomes in long sleepers: The societal sleep restriction hypothesis.

Society imposes work and school schedules, as well as social expectations, that militate against consistently obtaining more than 7-9 h of sleep every 24 h. For most but not all adults this sleep duration is adequate. But among those who consistently obtain more than 9 h of sleep per day ("long sleepers"), there likely exists a subpopulation of individuals who are nevertheless failing to obtain enough sleep to satisfy their physiological sleep needs - a consequence of "restricting" their daily sleep durations to whatever extent they can tolerate so as to conform as closely as possible to society's norms and expectations.

Dimensions and predictors of clinical and personal recovery in first-episode psychoses: Results from a cross-sectional study.

Introduction: First episode psychosis (FEP) services ensure higher recovery rates compared to usual care. The aim of this study was to investigate the different dimensions of recovery and its predictors.

Methods: This cross-sectional study recruited within those admitted to the Ferrara FEP service since 2012 that at the time of analysis were still receiving psychiatric care.
