Study: A hangover may affect your ability to concentrate or drive

In a new analysis, researchers at the University of Bath in the UK analyzed previous studies on people who had a blood alcohol content of zero or close to zero after a night of heavy drinking. They found that during a hangover, people still showed impairments in attention, short- and long-term memory, coordination, and reaction time.

“These results have quite significant implications for things like workplace performance or activities like driving,” Sally Adams, the senior author of the study and assistant professor at the University of Bath, told BuzzFeed News. “You might still be impaired even after most of the alcohol has left your system.”
