Hangover Cure Myths Busted: Science Reveals No Instant Fix, Prevention is Key

  • There is no instant cure for a hangover; prevention (drinking less or not at all) is the only guaranteed method.
  • Hangovers are caused by toxic acetaldehyde and inflammation, not just dehydration, affecting the body's recovery.
  • Factors like genetics, type of alcohol (congeners in darker drinks), and sleep disruption influence hangover severity.
  • While hydration (especially with electrolytes) and eating can help mitigate symptoms, most commercial "cures" lack scientific backing.
  • Rest, sleep, and time are the only reliable solutions for recovery, as the body processes alcohol at a fixed rate.

Why It Matters: Science confirms no magic hangover cure; prevention, moderation, and time are the only effective strategies.
