Association between night shift work, melatonin and estradiol in nurses
Synthesis of melatonin is regulated through visible light exposure, with peak production during the night. Melatonin regulates various physiological processes including secretion of other hormones, and has anticarcinogenic properties as demonstrated in animal and in vitro experiments. It has been suggested that night shift work (exposure to light at night) may disrupt circadian rhythm, and mela...
متن کاملShift Work, Chronotype, and Melatonin Patterns among Female Hospital Employees on Day and Night Shifts.
BACKGROUND Shift work-related carcinogenesis is hypothesized to be mediated by melatonin; however, few studies have considered the potential effect modification of this underlying pathway by chronotype or specific aspects of shift work such as the number of consecutive nights in a rotation. In this study, we examined melatonin patterns in relation to shift status, stratified by chronotype and n...
متن کاملEfficacy and hypnotic effects of melatonin in shift-work nurses: double-blind, placebo-controlled crossover trial
BACKGROUND Night work is associated with disturbed sleep and wakefulness, particularly in relation to the night shift. Circadian rhythm sleep disorders are characterized by complaints of insomnia and excessive daytime sleepiness that are primarily due to alterations in the internal circadian timing system or a misalignment between the timing of sleep and the 24-h social and physical environment...
متن کاملLight 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...
