Previous research has shown that sleep quality in hemodialysis patients is disturbed. One of the possible explanations is an insufficient or disturbed melatonin rhythm. Melatonin rhythm is regulated by exposure to light. In this feasibility study, the investigators examine the effects of light therapy during dialysis on sleep, melatonin rhythm and mood.

This intervention study will investigate the effect of therapy light rooms on sleep, circadian rhythms, mood, behavioural problems and function in nursing home (NH) patients with dementia.
The aim of this study is to demonstrate the efficacy of timed exposure to bright light for the treatment of disturbed nighttime sleep and daytime wake in community-dwelling dementia patien...
In a 3 years longitudinal, observational, multicentre study, about 500 women will be recruited and followed-up from early pregnancy (10-15 gestational week) until 12 months after delivery....
Disruption of sleep and alertness is one of the most disabling non-motor symptoms of Parkinson's disease (PD). Mechanisms leading to impaired sleep and alertness in PD are not well underst...
The aim of this study is to determine if altering the pattern of one's sleep and having light therapy can speed up the treatment of depression. In the UK, the large majority of patients wi...
Although physical activity (PA) is associated with a reduction of a wide range of sleep problems, it remains uncertain whether complying with the international guidelines of 150 min of moderate to vi...
Children's sleep problems are associated with poorer student functioning in the school environment, including impairment in peer relationships; yet, no studies have examined sleep functioning in relat...
Childhood sleep problems are associated with insufficient parental sleep and adverse maternal mental health symptoms, which may be exacerbated when mothers/toddlers co-sleep (i.e., bed/room sharing). ...
In view of the multiple and diversity of sleep disorders, this paper develops and designs mobile portable devices based on remote monitoring and assessment of sleep quality. Using psychological scale,...
For treating affective disorders like SAD, light therapy is used although the underlying mechanism explaining this success remains unclear. To accelerate the research on defining the light characteris...
Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; includes Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep.
Light-induced change in a chromophore, resulting in the loss of its absorption of light of a particular wave length. The photon energy causes a conformational change in the photoreceptor proteins affecting PHOTOTRANSDUCTION. This occurs naturally in the retina (ADAPTATION, OCULAR) on long exposure to bright light. Photobleaching presents problems when occurring in PHOTODYNAMIC THERAPY, and in FLUORESCENCE MICROSCOPY. On the other hand, this phenomenon is exploited in the technique, FLUORESCENCE RECOVERY AFTER PHOTOBLEACHING, allowing measurement of the movements of proteins and LIPIDS in the CELL MEMBRANE.
Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
Movements or behaviors associated with sleep, sleep stages, or partial arousals from sleep that may impair sleep maintenance. Parasomnias are generally divided into four groups: arousal disorders, sleep-wake transition disorders, parasomnias of REM sleep, and nonspecific parasomnias. (From Thorpy, Sleep Disorders Medicine, 1994, p191)
Treatment using irradiation with light of low power intensity so that the effects are a response to the light and not due to heat. A variety of light sources, especially low-power lasers are used.
Sleep disorders disrupt sleep during the night, or cause sleepiness during the day, caused by physiological or psychological factors. The common ones include snoring and sleep apnea, insomnia, parasomnias, sleep paralysis, restless legs syndrome, circa...
