Cognitive function and brain plasticity in a rat model of shift work: role of daily rhythms, sleep and glucocorticoids
Marti, Andrea Rørvik; Pedersen, Torhild; Wisor, Jonathan P.; Mrdalj, Jelena; Holmelid, Øystein; Patil, Sudarshan; Meerlo, Peter; Bramham, Clive R.; Grønli, Janne (Journal article; Peer reviewed, 2020)Many occupations require operations during the night-time when the internal circadian clock promotes sleep, in many cases resulting in impairments in cognitive performance and brain functioning. Here, we use a rat model ... -
Effects of a work schedule with abated quick returns on insomnia, sleepiness and work-related fatigue. Results from a large-scale cluster randomized controlled trial
Djupedal, Ingebjørg Louise Rockwell; Harris, Anette; Svensen, Erling; Pallesen, Ståle; Waage, Siri; Nielsen, Morten Birkeland; Sunde, Erlend; Bjorvatn, Bjørn; Holmelid, Øystein; Vedaa, Øystein (Journal article; Peer reviewed, 2024)Study objectives To investigate the effect of a work schedule with abated quick returns (i.e., >11 hours between two shifts) on insomnia, daytime sleepiness, and work-related fatigue compared to a shift schedule maintaining ... -
Protocol for a systematic review and meta-analysis on the associations between shift work and sickness absence
Sunde, Erlend; Harris, Anette Kristoffersen; Nielsen, Morten Birkeland; Bjorvatn, Bjørn; Lie, Stein Atle; Holmelid, Øystein; Vedaa, Øystein; Waage, Siri; Pallesen, Ståle (Journal article; Peer reviewed, 2022)Background Shift work, i.e., non-standard work hours, has been associated with both short- and long-term sickness absence. However, findings are inconsistent and inconclusive. Thus far, no comprehensive meta-analytic ... -
Simulated Night Work, Sleep-Wake Changes and Markers of Brain Plasticity
Holmelid, Øystein (Master thesis, 2019-11-21)Nattarbeid skjer i et tidsvindu hvor kroppen er innstilt på å sove og muligheten for å sove er når kroppen er innstilt på å være våken. Dette påvirker søvn og våkenhetsmønstre, samt kognitiv fingering. Jeg har brukt en ... -
Simulated quick returns in a laboratory context and effects on sleep and pre-sleep arousal between shifts: a crossover controlled trial
Holmelid, Øystein; Pallesen, Ståle; Bjorvatn, Bjørn; Sunde, Erlend; Waage, Siri; Vedaa, Øystein; Nielsen, Morten Birkeland; Djupedal, Ingebjørg Louise Rockwell; Harris, Anette (Journal article; Peer reviewed, 2024)This trial presents a laboratory model investigating the effect of quick returns (QRs, <11 h time off between shifts) on sleep and pre-sleep arousal. Using a crossover design, 63 participants worked a simulated QR condition ...
