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 ... -
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 ... -
No escaping the rat race: simulated night shift work alters the time-of-day variation in BMAL1 translational activity in the prefrontal cortex
Marti, Andrea Rørvik; Patil, Sudarshan; Mrdalj, Jelena; Meerlo, Peter; Skrede, Silje; Pallesen, Ståle; Pedersen, Torhild; Bramham, Clive R.; Grønli, Janne (Peer reviewed; Journal article, 2017-10-04)Millions of people worldwide work during the night, resulting in disturbed circadian rhythms and sleep loss. This may cause deficits in cognitive functions, impaired alertness and increased risk of errors and accidents. ... -
Shift in Food Intake and Changes in Metabolic Regulation and Gene Expression during Simulated Night-Shift Work: A Rat Model
Marti, Andrea Rørvik; Meerlo, Peter; Grønli, Janne; Hasselt, Sjoerd van; Mrdalj, Jelena; Pallesen, Ståle; Pedersen, Torhild; Henriksen, Tone Elise Gjøtterud; Skrede, Silje (Journal article; Peer reviewed, 2016)Night-shift work is linked to a shift in food intake toward the normal sleeping period, and to metabolic disturbance. We applied a rat model of night-shift work to assess the immediate effects of such a shift in food intake ...
