The dynamics of cyclic‐periodic phenomena during non‐rapid and rapid eye movement sleep
Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Sleep is a complex physiological state characterized by distinct stages, each exhibiting unique electroencephalographic patterns and physiological phenomena. Sleep research has unveiled the presence of intricate cyclic‐periodic phenomena during both non‐rapid eye movement and rapid eye movement sleep stages. These phenomena encompass a spectrum

Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it

Journal of Sleep Research, EarlyView.ABSTRACT Sleep‐related breathing disorders (SRBD) represent a significant paediatric health concern. Traditional polysomnographic indices, such as the apnoea–hypopnoea index, may not fully capture the physiological burden of paediatric SRBD, highlighting the need to better characterise the impact of nocturnal hypoxemia on cardiac autonomic regulation ...

A Personalized Recovery Intervention to Support Sleep Health in Emergency Healthcare Professionals
Journal of Sleep Research, EarlyView.ABSTRACT Optimizing sleep health in healthcare professionals is a challenge, as misalignment between endogenous circadian rhythms and exogenous work schedules undermines recovery, well‐being, and performance. This study evaluated a tailored recovery intervention based on cognitive‐behavioural approaches for insomnia designed to support recovery to ...
