An Actigraphy-Based Validation Study of the Sleep Disorder Inventory in the Nursing Home
Hjetland, Gunnhild Johnsen; Nordhus, Inger Hilde; Pallesen, Ståle; Cummings, Jeffrey; Tractenberg, Rochelle E.; Thun, Eirunn; Kolberg, Eirin; Flo, Elisabeth (Journal article; Peer reviewed, 2020-03-13)Background: Disrupted sleep is common among nursing home patients with dementia and is associated with increased agitation, depression, and cognitive impairment. Detecting and treating sleep problems in this population are ... -
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 ... -
Ambient bright light treatment improved proxy-rated sleep but not sleep measured by actigraphy in nursing home patients with dementia: a placebo-controlled randomised trial
Hjetland, Gunnhild J.; Kolberg, Eirin; Pallesen, Ståle; Thun, Eirunn; Nordhus, Inger Hilde; Bjorvatn, Bjørn; Flo-Groeneboom, Elisabeth (Journal article; Peer reviewed, 2021-05-17)Background: Up to 70% of nursing home patients with dementia suffer from sleep problems. Light is the main zeitgeber to the circadian system and thus has a fundamental impact on sleep-wake behaviour. Low indoor light levels ... -
The Association Between Shift Work and Immunological Biomarkers in Nurses
Bjorvatn, Bjørn; Axelsson, John; Pallesen, Ståle; Waage, Siri; Vedaa, Øystein; Blytt, Kjersti Marie; Buchvold, Hogne Vikanes; Moen, Bente Elisabeth; Thun, Eirunn (Journal article; Peer reviewed, 2020)Objectives: Shift work is associated with several negative health effects. The underlying pathophysiological mechanisms are unclear, but low-grade inflammation has been suggested to play a role. This project aimed to ... -
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 ... -
The effects of bright light treatment on affective symptoms in people with dementia: a 24-week cluster randomized controlled trial
Kolberg, Eirin; Hjetland, Gunnhild Johnsen; Thun, Eirunn; Pallesen, Ståle; Nordhus, Inger Hilde; Husebø, Bettina; Flo-Groeneboom, Elisabeth (Journal article; Peer reviewed, 2021)Background: The majority of people with dementia have behavioral and psychological symptoms of dementia (BPSD), including depression, anxiety and agitation. These may be elicited or aggravated by disrupted circadian rhythms. ... -
The effects of bright light treatment on subjective and objective sleepiness during three consecutive night shifts among hospital nurses – a counter-balanced placebo-controlled crossover study
Bjorvatn, Bjørn; Pallesen, Ståle; Waage, Siri; Thun, Eirunn; Blytt, Kjersti Marie (Journal article; Peer reviewed, 2021)Objectives The objective was to investigate effects of timed bright light treatment on subjective and objective measures of sleepiness during three consecutive night shifts among hospital nurses. Methods Thirty-five ... -
Insufficient melanopic equivalent daylight illuminance in nursing home dementia units across seasons and gaze directions
Kolberg, Eirin; Pallesen, Ståle; Hjetland, Gunnhild Johnsen; Nordhus, Inger Hilde; Thun, Eirunn; Flo-Groeneboom, Elisabeth (Journal article; Peer reviewed, 2022)Adequate illumination plays an important part in providing a healthy environment for nursing home patients with dementia. With increasing awareness of non-visual responses to light, new approaches to quantifying illuminance ... -

Vedaa, Øystein; Harris, Anette; Waage, Siri; Bjorvatn, Bjørn; Thun, Eirunn; Buchvold, Hogne Vikanes; Djupedal, Ingebjørg Louise Rockwell; Pallesen, Ståle (Journal article, 2020)Objective: This study aimed to investigate how change in the number of quick returns [(QR) <11 hours between consecutive shifts] longitudinally is associated with risk of occupational accidents among nurses. Methods: ... -
A national survey on how sexual activity is perceived to be associated with sleep
Pallesen, Ståle; Waage, Siri; Thun, Eirunn; Andreassen, Cecilie Schou; Bjorvatn, Bjørn (Peer reviewed; Journal article, 2020)There is a paucity of studies investigating how sexual activity is perceived to influence sleep, despite conceptions about significant gender differences regarding this issue. In all, 4000 persons, aged between 18 and 55 ... -
