A hangover is the unwelcome aftermath of overindulging in alcohol. When you consume alcohol, it triggers various effects on your body that can lead to a hangover the next day.

While no studies proved coffee could help a hangover, one study pointed to caffeine playing a key role. When mixed with over-the-counter (OTC NSAIDs) drugs such as Aspirin or Ibuprofen, it was shown to help with the head-pounding after effects of alcohol by aiding to block acetate.²

Here's the findings:

  • Caffeine can block ethanol-induced hypersensitivity.²
  • Caffeine may ease other hangover symptoms like malaise and fatigue.²
  • When combined with a NSAID drug, hangover benefits are observed.²

Is Coffee Good For Hangover Headache?

No, based on the caffeine research, it may aid with hangover symptoms such as malaise and fatigue but not the hangover headache.

The specific study is done not on coffee, rather on the combination of caffeine and pain killer drugs (like Aspirin). The pain killer drug plays a specific role with the headache, so it does not appear that coffee on its own would be effective.

Caffeine Hangover

Surprisingly, caffeine in itself can cause hangover symptoms from sources like coffee, noted as a caffeine hangover.¹²

A caffeine hangover usually happens 12-24 hours after consumption, like from your last cup of coffee. And it's usually related to a high caffeine amount, but can happen with moderate amounts.

  • headache
  • fogginess
  • fatigue
  • jitteriness or anxiousness 
  • poor sleep
  • poor concentration
  • light and noise sensitivity

Is Coffee Good After Drinking Alcohol?

Yes, coffee can be good after drinking alcohol, specifically due to the caffeine content.

The combination of caffeine and over-the-counter anti-inflammatory medication was found to be most effective about 4 hours after drinking.⁴ This is due to it helping to block acetate when levels are most likely to spike after drinking, which is found to be a potential culprit in the negative effects of alcohol.
