- Medical consensus across new holiday guidance says there is no reliable cure for hangovers, so prevention through moderation, pacing and hydration is key.
- Experts urge replacing lost salts with electrolyte drinks, oral rehydration solutions or potassium‑rich foods such as bananas, leafy greens and potatoes.
- NHS advice highlights fluids, light food and appropriate painkillers for symptom relief, noting that only time resolves a hangover.
- Clinicians warn to avoid acetaminophen/paracetamol after drinking due to liver risk, suggesting ibuprofen for headaches if needed.
- Coffee remains contested: pharmacists advise skipping it because it can worsen dehydration, while some doctors allow limited caffeine for alertness without claiming it as a cure.
