Effects of alcohol still present day after heavy drinking session – study

The effects of a boozy bank holiday drinking session could last longer than you think, a new study suggests.

The cognitive impairments seen when people are drunk are still present the day after, when there is little to no alcohol left in the bloodstream.

Psychologists at the University of Bath have discovered that hungover people have poorer attention, memory and psychomotor skills such as co-ordination and speed compared to when sober.

The researchers suggest their findings have important implications when it comes to activities performed when hungover, including driving.

For example, while hungover, individuals might typically wait until they believe there is no alcohol in the system before driving.

These new results suggest that we could still be impaired in terms of the cognitive processes required, even after alcohol has left the bloodstream.

In addition, the researchers warn that although many workplaces have clear policies in place regarding alcohol intoxication at work, few cover the next-day effects of alcohol.

For certain jobs, they suggest, employees should be aware of the real effects that hangovers can have, and employers might do well to consider revising guidelines on safety grounds.

The hangover is the most commonly reported negative consequence of alcohol use and is already estimated to cost the UK economy £1.9 billion a year due to absenteeism.

Despite this, up until this point little has been done to examine the effects of being hungover “on the job”.

Lead author Craig Gunn said: “In our review of 19 studies we found that hangover impaired psychomotor speed, short and long-term memory and sustained attention.

“Impaired performance in these abilities reflects poorer concentration and focus, decreased memory and reduced reaction times the day after an evening of heavy drinking.

“Our review also indicated limited and inconsistent research on alcohol hangover and the need for future studies in the field.”

The researchers are now developing this work to further examine the true health and economic costs of hangover and associated risks with the next-day effects of heavy drinking.

Dr Sally Adams, senior author, added: “Our findings demonstrate that hangover can have serious consequences for the performance of everyday activities such as driving and workplace skills such as concentration and memory.

“These findings also highlight that there is a need for further research in this field where alcohol hangover has implications at the individual level in terms of health and wellbeing, but also more widely at the national level for safety and the economy.”

The meta-analysis involved in this study involved a review of 770 articles relating to the topic.

– The study, A Systematic Review Of The Effects Of Alcohol Hangover On Cognitive Performance, is published in the journal Addiction.
