Light exposure and melatonin among rotating shift nurses--letter.
Grundy and colleagues (1) conducted a study into how light influencesmelatonin in nurses during rotating shifts. Inter alia, it was concluded that the examined "two-12hour-days/two-12-hour-nights/5-days-off" pattern minimally disrupts melatonin production. Interestingly, chronotype information was obtained but appeared to have negligible effects on shift-work–melatonin relationships. The author...
متن کاملThe influence of light at night exposure on melatonin levels among Canadian rotating shift nurses.
BACKGROUND Shift work has been identified as a risk factor for several cancer sites in recent years, with melatonin as a potential intermediate on the proposed causal pathway. This study examined the influence of nighttime light exposure on melatonin levels among 123 rotating shift nurses. METHODS Nurses working a rotating shift schedule (two 12-hour days, two 12-hour nights, and five days of...
متن کاملEffects of Rotating Night Shift and Exposure of Light at Night on Circadian Pattern of Salivary Cortisol and Urinary Melatonin Levels
Objectives: The objective of the present study was to investigate the effects of rotating night shift and light exposure at night on circadian pattern of salivary cortisol and urinary melatonin levels. Methods: 62 healthy nursing professionals of both genders performing day and night shifts (continuous 9 days night shift with alternate day shifts) were recruited. Each month scheduled to continu...
متن کاملCircadian variation of melatonin, light exposure, and diurnal preference in day and night shift workers of both sexes.
BACKGROUND Light-at-night has been shown in experimental studies to disrupt melatonin production but this has only partly been confirmed in studies of night shift workers. In this cross-sectional study, we examined the circadian variation of melatonin in relation to shift status, individual levels of light-at-night exposure, and diurnal preference, an attribute reflecting personal preference fo...
متن کاملExposure to room light before bedtime suppresses melatonin onset and shortens melatonin duration in humans.
CONTEXT Millions of individuals habitually expose themselves to room light in the hours before bedtime, yet the effects of this behavior on melatonin signaling are not well recognized. OBJECTIVE We tested the hypothesis that exposure to room light in the late evening suppresses the onset of melatonin synthesis and shortens the duration of melatonin production. DESIGN In a retrospective anal...
