  • Title: [Bright light treatment against sleep disturbances in nursing homes--a non-pharmacological alternative].
    Author: Fetveit A, Bjorvatn B.
    Journal: Tidsskr Nor Laegeforen; 2005 Jun 16; 125(12):1679-81. PubMed ID: 15976841.
    Abstract:
    BACKGROUND: Age-related sleep disturbances may be caused by changes in the circadian rhythm, either by phase shifting and/or by a reduction of its amplitude. This may result in less nocturnal sleep and less wakefulness during the day. MATERIAL AND METHODS: The article is based on our own research and on relevant studies and reviews in this field. RESULTS AND INTERPRETATION: Bright light treatment may alter the phase and strengthen the existing circadian rhythm in patients with insomnia, thus creating a clearer distinction between night and day. It is reported that bright light treatment in the morning for patients with dementia may improve sleep maintenance.
