The alcohol hangover and its potential impact on the UK armed forces: a review of the literature on post-alcohol impairment.

Abstract

OBJECTIVE: To raise awareness within the Defence Medical Services regarding the potential effect of post-alcohol impairment / alcohol hangover. METHOD: Literature relating to post-alcohol impairment / alcohol hangover, and the evidence for impairment is reviewed, with discussion relating to UK Armed Forces. CONCLUSION: The evidence for performance impairment during alcohol hangover is not conclusive. Until further evidence is available policy should acknowledge the potential for impaired functioning, particularly the morning after a heavy drinking session, and even when blood alcohol has returned to zero. Recommendations for clinical practice and areas for further research are presented.
