A randomized controlled trial on the effect of blue-blocking glasses compared to partial blue-blockers on melatonin profile among nulliparous women in third trimester of the pregnancy
Liset, Randi; Grønli, Janne; Henriksen, Roger Ekeberg; Gjøtterud Henriksen, Tone Elise; Nilsen, Roy Miodini; Pallesen, Ståle (Journal article; Peer reviewed, 2022)Objective In pregnancy melatonin regulates circadian rhythms, induce sleep, and has a neuroprotective positive effect on fetal development. Artificial blue light in the evening delays and suppresses melatonin production. ... -
A randomized controlled trial on the effects of blue-blocking glasses compared to partial blue-blockers on sleep outcomes in the third trimester of pregnancy
Liset, Randi; Grønli, Janne; Henriksen, Roger Ekeberg; Henriksen, Tone Elise Gjøtterud; Nilsen, Roy Miodini; Pallesen, Ståle (Journal article; Peer reviewed, 2022)Objective Sleep disturbances are common in pregnancy. Blocking blue light has been shown to improve sleep and may be a suitable intervention for sleep problems during pregnancy. The present study investigated the effects ... -
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 ... -
Shift Work Disorder in Nurses – Assessment, Prevalence and Related Health Problems
Flo, Elisabeth; Pallesen, Ståle; Magerøy, Nils; Moen, Bente E.; Grønli, Janne; Nordhus, Inger Hilde; Bjorvatn, Bjørn (Peer reviewed; Journal article, 2012-04-02)Background: This study investigates the prevalence of symptoms of shift work disorder in a sample of nurses, and its association to individual, health and work variables. Methodology/Principal Findings: We investigated ... -
Sleep and protein synthesis-dependent synaptic plasticity: impacts of sleep loss and stress
Grønli, Janne; Soule, Jonathan; Bramham, Clive R. (Peer reviewed; Journal article, 2014-01-21)Sleep has been ascribed a critical role in cognitive functioning. Several lines of evidence implicate sleep in the consolidation of synaptic plasticity and long-term memory. Stress disrupts sleep while impairing synaptic ... -
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 ... -
Sleep, evening light exposure and perceived stress in healthy nulliparous women in the third trimester of pregnancy
Liset, Randi; Grønli, Janne; Henriksen, Roger Ekeberg; Henriksen, Tone Elise Gjøtterud; Nilsen, Roy Miodini; Pallesen, Ståle (Journal article; Peer reviewed, 2021)Objective Sleep disturbances are common in pregnancy, and the prevalence increases during the third trimester. The aim of the present study was to assess sleep patterns, sleep behavior and prevalence of insomnia in pregnant ... -
Time-of-Day Effects in Resting-State Functional Magnetic Resonance Imaging: Changes in Effective Connectivity and Blood Oxygenation Level Dependent Signal
Vaisvilaite, Liucija; Hushagen, Vetle; Grønli, Janne; Specht, Karsten (Journal article; Peer reviewed, 2021)Introduction: In the light of the ongoing replication crisis in the field of neuroimaging, it is necessary to assess the possible exogenous and endogenous factors that may affect functional magnetic resonance imaging (fMRI). ... -
Validation of peripheral arterial tonometry as tool for sleep assessment in chronic obstructive pulmonary disease
Holmedahl, Nils Henrik; Fjeldstad, Odd-Magne; Engan, Harald; Saxvig, Ingvild W.; Grønli, Janne (Peer reviewed; Journal article, 2019-12-18)Obstructive sleep apnea (OSA) worsens outcomes in Chronic Obstructive Pulmonary Disease (COPD), and reduced sleep quality is common in these patients. Thus, objective sleep monitoring is needed, but polysomnography (PSG) ...
