“…Rheaume et al . provided three case reports of the effect of bright light therapy on sleep in older males with dementia and night‐time sleep disturbances 45 . The facility in which these residents lived had a bright light therapy room fitted with fluorescent lights that provided light intensity at eye level of 2500 lux throughout the entire room.…”

“…The first participant displayed a reduction in night‐time awakening after 1 month of bright light therapy. In this case the resident was placed in the light therapy room when he awoke in the night (generally 03.00 hours), and remained seated in the light room for 3–4 h, although it is reported that he fell asleep within 30 min of being placed in the room 45 . The second participant experienced difficulties establishing sleep and frequent waking.…”

Executive summary Background The promotion of sleep in older adults is a significant issue in high‐level residential aged care facilities, with as many as 67% of residents experiencing disruptions to their sleep patterns. Not only do health concerns such as cognitive impairment, pain and incontinence impact upon this population's sleep quality and quantity, but environmental factors including noise, light and night‐time nursing care also affect sleep of those residing in institutions. In order to address the issue of sleep disruption, assessment and diagnosis of sleep problems and implementation of interventions that are effective in promoting sleep are essential. Objectives The objective of this review was to determine the most effective tools for the assessment and diagnosis of sleep in older adults in high‐level aged care. The review also sought to determine the most effective strategies for the promotion of sleep in this population. Outcome measures for this review were: indicators of improved sleep quality and quantity, including an improvement in daytime functioning and improved night‐time sleep; reduction in use of hypnotics and sedatives; and increased satisfaction with sleep. Search strategy A literature search was performed using the following databases for the years 1993–2003: AgeLine, APAIS Health, CINAHL, Cochrane Library, Current Contents, Dissertation Abstracts International, Embase, Medline, Proquest, PsycInfo, Science Citations Index. A second search stage was conducted through review of reference lists of studies retrieved during the first search stage. The search was limited to published and unpublished material in English language. Selection criteria The review was limited to papers addressing sleep diagnosis, assessment and/or management in adults aged 65 or over who were residing in high‐level aged care. The review included randomised controlled trials (RCTs) and, due to the limited number of RCTs available, non‐RCTs, cohort and case control studies and qualitative research were also considered for inclusion. Research was included if it addressed the assessment, diagnosis or management of sleep using outcome measure of improved night‐time sleep or daytime function, improvements in resident satisfaction with sleep or reduction in medication use associated with sleep. The types of interventions considered by this review were alternative therapies including massage, aromatherapy and medicinal herbs; behavioural or cognitive interventions; biochemical interventions; environmental interventions; pharmacological interventions and related nocturnal interventions such as continence care. Instruments and strategies to diagnose and assess the sleep of older high‐level care residents, including objective and subjective assessment tools, were considered by this review. Data collection and analysis All retrieved papers were critically appraised for eligibility for inclusion and methodological quality independently by two reviewers, and the same reviewers collected details of eligible research.

“…This treatment encompasses an increase of the general illuminance in rooms by ceiling-mounted lighting in order for non-image forming effects of light to take place. Studies by Rheaume et al [5], van Someren et al [6], Riemersma-van der Lek et al [7], van Hoof et al [8,9], Sloane et al [10,11] and Barrick et al [12], which exposed institutionalised people with dementia to ambient bright light through ceiling-mounted luminaires, showed short-term and long-term effects such as lessened nocturnal unrest, a more stable sleep-wake cycle, possible improvement to restless and agitated behaviour as well as sleep, increased amplitude of the circadian body temperature cycle, and a lessening of cognitive decline. To date, it is unknown how long effects of bright light last and how to predict which persons respond positively to light treatment.…”

Light therapy is increasingly administered and studied as a non-pharmacologic treatment for a variety of healthrelated problems, including treatment of people with dementia. Light therapy comes in a variety of ways, ranging from being exposed to daylight, to being exposed to light emitted by light boxes and ambient bright light. Light therapy is an area in medicine where medical sciences meet the realms of physics, engineering and technology. Therefore, it is paramount that attention is paid in the methodology of studies to the technical aspects in their full breadth. This paper provides an extensive introduction for non-technical researchers on how to describe and adjust their methodology when involved in lighting therapy research. A specific focus in this manuscript is on ambient bright light, as it is an emerging field within the domain of light therapy. The paper deals with how to (i) describe the lighting equipment, (ii) describe the light measurements, (iii) describe the building and interaction with daylight. Moreover, attention is paid to the uncertainty in standards and guidelines regarding light and lighting for older adults.

“…Another approach that is gaining popularity, both from a research, ethical and practical point of view, is to increase the general illuminance in rooms where people with dementia spend their days to a high level [22]. Studies by Rheaume et al [23], van Someren et al [24], Riemersma-van der Lek et al [25], and van Hoof et al [5] that exposed institutionalised people with dementia to ambient bright light through ceiling-mounted luminaires showed short-term and long-term effects as lessened nocturnal unrest, a more stable sleepwake cycle, possible improvement to restless and agitated behaviour, increased amplitude of the circadian body temperature cycle, and possible improvements to sleep. Still, the field of study is new and lighting equipment used needs to be researched and modelled in more detail, both in laboratory and field settings.…”
