The aim of this study was to determine the relationship between total sleep time and the duration and severity of the alcohol hangover.Methods: A survey was conducted among Dutch University students to collect data on their latest alcohol hangover. Data on alcohol consumption, total sleep time, hangover severity, and duration were collected. Alcohol consumption and hangover severity and duration were compared for participants who (a) slept 7 hours.Results: Data from N=578 students (40.1% men and 59.9% women) were included in the statistical analyses. Significant correlations were found between total sleep time and alcohol consumption (r=0.117, p=0.005), hangover severity (r= –0.178, p=0.0001) and hangover duration (r=0.168, p=0.0001). In contrast, total alcohol consumption did not correlate significantly with overall hangover severity or duration. Those who slept longer than 7 hours consumed significantly more alcohol (p=0.016) and reported extended hangover duration (p=0.004). However, they also reported significantly less severe hangovers (p=0.001) than students who slept
