What this trial studies

This clinical trial aims to evaluate the impact of melatonin on the sleep patterns of resident trainees working night float shifts in various medical specialties. Participants will be randomized to receive either melatonin or a placebo, with their sleep monitored using portable EEG devices over a 12-day period. The study will assess changes in sleep quality and quantity, particularly focusing on deep sleep and REM sleep, to determine if melatonin can effectively improve sleep during demanding night shifts.

Why it matters

Potential benefit: If successful, this study could provide a non-invasive method to enhance sleep quality for medical residents, potentially improving their overall performance and well-being.

How similar studies have gone: Previous studies have shown that melatonin can effectively realign circadian rhythms and improve sleep quality in shift workers, suggesting potential success for this approach.
