Hangxiety, short for hangover anxiety, is the colloquial term that refers to the anxiety some people experience during a hangover following alcohol consumption. It describes the sense of worry, stress, and unease that can occur alongside the physical symptoms of a hangover, such as headache, nausea, and fatigue. Hangxiety affects about 12% of people.

The cause of hangxiety has not been identified.

Hangxiety can manifest in various ways, such as racing thoughts, a sense of dread, increased heart rate, or feelings of guilt or regret about actions taken while under the influence of alcohol. It can be experienced by anyone who consumes alcohol, but individuals with underlying anxiety disorders or mental health conditions may be more susceptible to this phenomenon.
