Circadian 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 کاملThe effect of Bright light on Fatigue and sleepiness in night shift work nurses

Methods: 44 healthy female shift work nurses were allocated into two groups of intervention and control. In the first stage, bright light was emitted to the nurses in the intervention group by the light box, and bright light was not emitted to the control group. In the nex...
متن کاملIncreased and mistimed sex hormone production in night shift workers.
BACKGROUND Night shift work has been associated with an increased risk for breast and prostate cancer. The effect of circadian disruption on sex steroid production is a possible underlying mechanism, underinvestigated in humans. We have assessed daily rhythms of sex hormones and melatonin in night and day shift workers of both sexes. METHODS We recruited 75 night and 42 day workers, ages 22 t...
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 کاملIncidence of metabolic syndrome among night-shift healthcare workers.
OBJECTIVE Night-shift work is associated with ischaemic cardiovascular disorders. It is not currently known whether it may be causally linked to metabolic syndrome (MS), a risk condition for ischaemic cardiovascular disorders. The syndrome presents with visceral obesity associated with mild alterations in glucidic and lipidic homeostasis, and in blood pressure. The aim of this study was to asse...
