Acute effects of a simulated quick return on subjective sleepiness, mood, and cognitive performance: A laboratory crossover controlled trial
Holmelid, Øystein; Harris, Anette; Pallesen, Ståle; Bjorvatn, Bjørn; Vedaa, Øystein; Waage, Siri; Nielsen, Morten Birkeland; Djupedal, Ingebjørg Louise Rockwell; Sunde, Erlend (Journal article; Peer reviewed, 2024)Sleep loss due to short time off between shifts has been proposed as a mechanism contributing to impaired functioning in occupational settings. This laboratory crossover trial (ClinicalTrials.gov identifier: NCT05162105, ... -
Alerting and Circadian Effects of Short-Wavelength vs. Long-Wavelength Narrow-Bandwidth Light during a Simulated Night Shift
Sunde, Erlend; Pedersen, Torhild; Mrdalj, Jelena; Thun, Eirunn; Grønli, Janne; Harris, Anette; Bjorvatn, Bjørn; Waage, Siri; Skene, Debra J.; Pallesen, Ståle (Journal article; Peer reviewed, 2020)Light can be used to facilitate alertness, task performance and circadian adaptation during night work. Novel strategies for illumination of workplaces, using ceiling mounted LED-luminaires, allow the use of a range of ... -
Blue-enriched white light improves performance but not subjective alertness and circadian adaptation during three consecutive simulated night shifts
Sunde, Erlend; Pedersen, Torhild; Mrdalj, Jelena; Thun, Eirunn; Grønli, Janne; Harris, Anette; Bjorvatn, Bjørn; Waage, Siri; Skene, Debra J.; Pallesen, Ståle (Journal article; Peer reviewed, 2020)Use of blue-enriched light has received increasing interest regarding its activating and performance sustaining effects. However, studies assessing effects of such light during night work are few, and novel strategies for ... -
Bright light exposure during simulated night work improves cognitive flexibility
Sunde, Erlend; Mrdalj, Jelena; Pedersen, Torhild Thue; Bjorvatn, Bjørn; Grønli, Janne; Harris, Anette Kristoffersen; Waage, Siri; Pallesen, Ståle (Journal article; Peer reviewed, 2022)Night work leads to sleepiness and reduced vigilant attention during work hours, and bright light interventions may reduce such effects. It is also known that total sleep deprivation impairs cognitive flexibility as measured ... -
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 ... -
Effects of light interventions for adaptation to night work : Simulated night work experiments
Sunde, Erlend (Doctoral thesis, 2021-03-12)In modern society, the need for 24-hr operation and services requires some people to work outside normal daytime work hours (i.e. shift work), including the night. For instance, healthcare, police, and transportation, are ... -
Hearing loss in the royal Norwegian navy: a cross-sectional study
Irgens-Hansen, Kaja; Sunde, Erlend; Bråtveit, Magne; Baste, Valborg; Oftedal, Gunnhild; Koefoed, Vilhelm F; Lind, Ola; Moen, Bente Elisabeth (Peer reviewed; Journal article, 2014-10-07)Objectives Prior studies have indicated a high prevalence of noise-induced hearing loss (NIHL) among Navy personnel; however, it is not clear whether this is caused by work on board. The present study aimed to assess the ... -
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 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 ... -
Sleep homeostasis and night work: a polysomnographic study of daytime sleep following three consecutive simulated night shifts
Pedersen, Torhild Thue; Sunde, Erlend; Wisor, Jonathan P.; Mrdalj, Jelena; Pallesen, Ståle; Grønli, Janne (Journal article; Peer reviewed, 2022)Purpose: Millions of people work at times that overlap with the habitual time for sleep. Consequently, sleep often occurs during the day. Daytime sleep is, however, characterized by reduced sleep duration. Despite preserved ... -
Velferdsholdninger og sosiale verdier i europeiske velferdsregimer: En tverrnasjonal undersøkelse av sosiale verdiers betydning for holdninger til velferdsstaten i tre ulike velferdsregimer
Sunde, Erlend (Master thesis, 2011-05-13)Background: Welfare states and the welfare policies in practice in welfare states have implications for population health. Studies have shown that attitudes towards welfare and welfare policies vary between welfare regimes, ...
