Zebra striping, the practice of alternating each alcoholic drink with a non-alcoholic one, is catching on: 34 percent of UK adults reported trying it in 2025. The strategy does help. Just not quite in the way people think it does.
The actual mechanism: total consumption
The body processes alcohol at a relatively fixed rate, roughly one standard drink per hour. In the US, a standard drink is about 14 grams of pure alcohol, which works out to a 5-ounce glass of wine, a 12-ounce beer, or 1.5 ounces of spirits. Drink faster than that, and blood alcohol concentration rises, driving intoxication and putting physiological stress on the body.
Zebra striping slows things down. Inserting a non-alcoholic drink into every other round extends the gaps between drinks and often means fewer drinks overall. Both outcomes lower peak BAC.
That matters beyond the next morning. Heavy drinking in a single session impairs decision-making, disrupts memory, and reduces inhibitory control. Research from Liverpool John Moores University on binge drinking found impairments in verbal fluency and attention-switching among heavy social drinkers. Zebra striping works as a brake, and there’s a social dimension too: holding a drink makes it easier to turn down the next round when everyone else is still going.
Why hydration isn’t the main story
The common version of the zebra striping pitch goes: alternating with water keeps you hydrated, which prevents hangovers. It’s more complicated than that.
Alcohol is a diuretic, so it does cause fluid loss, and drinking water alongside alcohol offsets some of that. This can ease symptoms like thirst, headaches, and dizziness. But dehydration and hangovers aren’t the same thing. Fixing your fluid balance doesn’t reliably prevent one.
Hangovers come from several directions at once: acetaldehyde, a toxic byproduct of alcohol metabolism; inflammation; disrupted sleep; and changes to immune response. How bad a hangover gets tracks closely with total alcohol consumed and how fast the body can clear it. Staying hydrated addresses one piece of a messier picture.
The carbonation detail most people miss
The choice of non-alcoholic drink matters more than most people realize. Carbonated mixers, sodas, sparkling water, speed up how quickly alcohol enters the bloodstream. The bubbles increase pressure in the stomach, pushing alcohol into the small intestine faster, which means a quicker rise in BAC. Fizzy drinks won’t make you more drunk overall, but they can front-load the intoxication.
When it works and when it doesn’t
Zebra striping only helps if you actually drink less. If the slower pace just means a longer night, or if lighter early drinks give way to stronger ones later, the benefit evaporates. The other complication: the self-control required to stick to the pattern tends to fade in exactly the conditions where it matters most.
After decades of research, there is still no reliable hangover cure. The evidence consistently shows the same thing: drink less, feel better the next day. Zebra striping is a useful tool if it gets you there. Whether it does depends on what you actually do with the slower pace.
