With office parties, family gatherings and long nights out filling calendars in the run-up to Christmas, many people may be hoping that eating a hearty meal before drinking will help ward off a festive hangover. New research suggests that strategy may not be as effective as commonly believed.
Academics at a Spanish university have found that eating before or during alcohol consumption does not reduce the likelihood of experiencing hangover symptoms, including headaches. The findings challenge advice often shared ahead of nights out, particularly during the busy festive season when alcohol intake tends to rise.
The study involved 32 adult participants, each of whom took part in three separate drinking sessions. Researchers recorded when participants ate, how much alcohol they consumed, and how they felt the following day, allowing them to assess which behaviours influenced hangover severity.
More than half of all drinking sessions resulted in headaches the next morning. However, researchers found no meaningful difference between participants who ate before drinking and those who did not. Eating while drinking alcohol also failed to reduce the chances of developing a headache. One of the most consistent findings was that thirst was the most commonly reported hangover symptom. Almost every participant experienced thirst the morning after drinking, and prolonged thirst was strongly linked to headaches. Researchers said this highlights dehydration as a key contributor to hangover discomfort — a factor that can be easily overlooked during late nights over Christmas and New Year.
After thirst, the next most common symptoms were a blocked or runny nose, followed by hunger. Participants also reported photophobia, or sensitivity to light, and phonophobia, meaning sensitivity to noise — symptoms that can make early Christmas mornings particularly uncomfortable.
The researchers concluded that while eating before drinking may help reduce immediate stomach upset, it does not appear to protect against next-day hangovers. Instead, the amount of alcohol consumed remains the strongest predictor of how severe symptoms will be.
If lining your stomach doesn't keep you from a terrible hangover, what does? Scientific evidence suggests that staying hydrated is one of the most effective ways to reduce hangover severity. Experts recommend drinking at least one glass of water for every alcoholic drink consumed. This helps counteract dehydration, which is a major contributor to headaches and fatigue, and can lessen other common symptoms such as dry mouth, dizziness, and lethargy.
As the festive season approaches and social drinking increases, the findings suggest that moderation, staying hydrated and allowing time for rest may be more effective ways to avoid spending Christmas Day or St Stephen’s Day nursing a hangover.
