Alternating Alcohol with Water Reduces Hangovers, Experts Say

From sipping pickle juice to applying lemon juice to underarms, many alcohol-loving Britons are desperate for a solution to avoid a hangover. Now, a new trend has emerged on social media known as "zebra striping," and scientists confirm it is genuinely effective.

The concept is straightforward: after consuming an alcoholic drink, you immediately switch to a non-alcoholic beverage before having another alcoholic one. One Instagram user described the method as essential for surviving a 7pm girls' dinner in Soho House followed by an early morning Pilates class. Another explained that by alternating wine with sparkling water, drinkers can enjoy 50 per cent less alcohol while remaining social and hydrated.

Does the strategy actually work? Psychologists Cathy Montgomery and Abi Rose from Liverpool John Moores University say yes, but with a significant caveat. They warn that the benefits vanish if people compensate by staying out later or switching to stronger drinks. In an article for The Conversation, the pair noted that the method only reduces hangovers if it leads to lower overall consumption.

Market data from KAM Insights supports the growing popularity of this tactic in the UK, with 34 per cent of adults reporting they have already tried it. The researchers describe zebra striping as a "useful pacing strategy."

The science behind the approach relies on how the body processes alcohol. Humans metabolise alcohol at a rate of roughly one standard UK unit per hour. Drinking faster than this rate causes blood alcohol concentration (BAC) to rise, leading to intoxication and increasing the risk of a hangover. By alternating alcoholic drinks with non-alcoholic alternatives, this method slows down overall consumption. This approach lowers peak BAC, meaning you are less intoxicated at any given moment, and reduces the total number of alcoholic drinks consumed.

Furthermore, zebra striping aids hydration. Alcohol acts as a diuretic, causing increased urination and fluid loss. By inserting non-alcoholic beverages between drinks, drinkers can counteract this effect and stay better hydrated throughout the night.

Experts warn that dehydration and electrolyte imbalances can occur following heavy drinking, prompting many British individuals to resort to unconventional remedies ranging from consuming pickle juice to applying lemon to the skin to mitigate hangover effects. To address the physiological stress of alcohol consumption, researchers suggest alternating alcoholic beverages with water or soft drinks throughout an evening out. This strategy aims to counteract the dehydration induced by drinking, potentially alleviating common symptoms such as intense thirst, dizziness, and headaches.

However, the study team emphasizes that the efficacy of this hydration strategy depends on the type of mixer used, advising against carbonated options. According to the researchers, carbonated drinks accelerate the rate at which alcohol enters the bloodstream, leading to a more rapid increase in Blood Alcohol Concentration (BAC). The mechanism involves bubbles increasing pressure within the stomach, which forces alcohol into the small intestine more quickly. While fizzy soft drinks do not necessarily result in higher overall intoxication levels, they can induce a state of drunkenness much faster than non-carbonated alternatives.

The severity of a hangover remains fundamentally linked to the total volume of alcohol consumed and the resulting BAC levels. As the experts noted, the greater the amount of alcohol ingested and the higher the BAC, the more likely and intense the hangover symptoms will be. Nevertheless, the concept of "zebra striping"—alternating drinks with non-alcoholic ones—offers a practical tool for managing social pressure to drink continuously. Holding a non-alcoholic beverage allows individuals to pause their consumption, making it easier to moderate intake. This approach is particularly relevant in the UK, where social drinking is deeply ingrained in cultural norms. Ultimately, the success of these mitigation strategies relies on the duration of the night out, the strength of the drinks consumed, and the ability to maintain a balanced approach to hydration and pacing.
