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

Narcolepsy and rapid eye movement sleep
Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Since the first description of narcolepsy at the end of the 19th Century, great progress has been made. The disease is nowadays distinguished as narcolepsy type 1 and type 2. In the 1960s, the discovery of rapid eye movement sleep at sleep onset led to improved understanding of core sleep‐related disease symptoms of the disease (excessive ...

Is sleep affected after microgravity and hypergravity exposure? A pilot study
Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Sleep is known to be affected in space travel and in residents of the international space station. But little is known about the direct effects of gravity changes on sleep, if other factors, such as sleep conditions, are kept constant. Here, as a first exploration, we investigated sleep before and after exposure to short bouts of microgravity ...

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.

Nonparametric methods in actigraphy: An update
Sleep Science, 2014 Circadian rhythmicity in humans has been well studied using actigraphy, a method of measuring gross motor movement. As actigraphic technology continues to evolve, it is important for data analysis to keep pace with new variables and features. Our objective is to study the behavior of two variables, interdaily stability and intradaily variability, to ...

Psychophysical changes after total sleep deprivation and experimental muscle pain
Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Sleep disturbances exacerbate chronic pain, increase psychological load, and increase inflammation. Delayed onset muscle soreness (DOMS) mimics aspects of chronic pain, predominantly affecting peripheral pain mechanisms, while experimental sleep provocations have been shown to impact central pain mechanisms.
