Overview
- Clinicians point to dehydration and electrolyte loss as key drivers of symptoms, recommending oral rehydration solutions, coconut water and salty broths.
- Dietitians advise hydrating soups and potassium‑rich foods over greasy fry‑ups, with a new Lifesum index placing miso and vegetable soups highest and the Full English lowest for recovery.
- Coffee does not accelerate alcohol clearance and may worsen dehydration, so experts suggest prioritizing water or electrolyte drinks if caffeine is used at all.
- For headaches, NSAIDs such as ibuprofen may help, whereas acetaminophen after heavy drinking poses liver risks; “hair of the dog” only delays recovery.
- Supplements like B vitamins and zinc are discussed as possible aids but remain weakly supported, and most sources stress that time, sleep and steady rehydration do the real work.
