Overview: Recent research indicates that common beliefs regarding hangover prevention are scientifically inaccurate. Studies suggest that mixing different types of alcohol does not inherently worsen symptoms compared to consuming specific high-congener liquors.
The Full Story
Numerous cultures maintain catchy sayings warning against consuming multiple alcoholic beverages within a single night, yet science has proven this to be a myth. Mixing drinks, per se, isn’t what aggravates hangover symptoms. For instance, cocktails such as vodka martinis and negronis utilize multiple liquors yet are considered hangover-proof, indicating that mixing itself is not the culprit. Instead, what appears to have an impact is the types of drinks being mixed. Research conducted in 2020 by the Society for the Study of Addiction indicates that varying levels of hangover severity are associated with different alcohol types, noting that mixing increases the probability of a stronger reaction. A 2010 publication in Current Drug Abuse Reviews established that spirits containing elevated levels of congeners are linked to more severe hangover symptoms. This means it might not actually matter if you drink wine before beer or vice versa, or that you’re even mixing them at all. Instead, it’s how much of the more hangover-inducing drink you’re consuming that determines how awful you’ll feel in the morning. According to the SSA, it’s also possible we experience “stronger” hangovers after mixing drinks simply because we expect them. Everything we feel during a hangover is, after all, subjective. If we believe that drinking a bunch of different types of liquor makes us feel worse, we’re more likely to evaluate our hangovers accordingly.
The fascinating thing about hangovers is that we still haven’t quite figured them out, so current research is slowly debunking all sorts of myths about them. Historical consensus held that alcohol-induced dehydration caused hangovers, yet a 2024 review in the journal Alcohol determined these are merely simultaneous effects of consumption rather than distinct causes. Significant evidence was not found to support the claim that water intake prevents or alleviates hangover symptoms. A 2024 review in Alcohol, Clinical and Experimental Research supports the theory that metabolic inflammation is the cause of hangovers. Opinions vary on whether coffee exacerbates hangovers or aids in symptom relief, though both views lack strong scientific backing. A 2010 survey of over 500 students at Utrecht University by The Open Neuropsychopharmacology Journal revealed no significant link between caffeine intake and hangover intensity. A 2014 publication in Addictive Behaviors regarding caffeinated beers corroborated these results. While it is frequently claimed that aging worsens hangover tolerance, a 2021 study in Alcohol and Alcoholism demonstrated the contrary. Senior participants reported fewer and less severe symptoms compared to younger groups. Researchers attributed this to lower alcohol consumption among experienced drinkers and a natural decrease in pain sensitivity as people age.
What This Means
Based on these findings, the focus for consumers should shift away from the order of consumption or hydration rituals toward understanding the chemical composition of the spirits themselves. The subjective nature of hangover perception suggests that psychological expectations play a significant role in how symptoms are evaluated and experienced.
Consumer Takeaway
For the drinker, the data suggests prioritizing moderation over specific beverage combinations to manage morning recovery. Understanding that inflammation drives the physical response rather than dehydration allows for more informed decisions regarding consumption habits without relying on unproven remedies like water or caffeine.
