   Understanding hangxiety: The link between alcohol and anxiety

   Journal of Psychiatric Nursing (Chouhan)Published Jan 1, 2025Checked Oct 14, 2026

   “The link between alcohol and anxiety Dear Editor,Alcohol consumption is a common social activity, yet its aftereffects can be distressing.Beyond the typical symptoms of a hangover-such as headache, nausea, and fatigue-many individuals experience heightened anxiety the day after drinking.This phenomenon, commonly referred to as "hangxiety," can range from mild unease to severe panic attacks.[1] Understanding the mechanisms behind hangxiety is crucial for developing effective coping strategies.Alcohol affects neurotransmitters by initially enhancing gamma-aminobutyric acid (GABA) activity, promoting relaxation and reducing anxiety.[1,2] However, as alcohol leaves the system, GABA levels drop while glutamate activity rises, leading to increased brain excitability and heightened anxiety.[1] Additionally, alcohol disrupts the hypothalamic-pituitary-adrenal (HPA) axis, causing a surge in cortisol levels post-consumption, [3] which contributes to stress and restlessness.Furthermore, alcohol-induced sleep disturbances, particularly reduced REM sleep, impair emotional regulation and can worsen anxiety symptoms the next day, creating a cycle of physiological and neurochemical imbalance.[3,4]”

   The role of emotion dysregulation, illness-related depression, and general anxiety in hangover anxiety.

   “arametric (lasso regression) models that are insensitive to multicollinearity were used to identify psychological factors most strongly associated with hangover anxiety.ResultsState-based emotion dysregulation was the most important explanatory factor in the random forest model, followed by illness-related depression, general anxiety, trait emotion dysregulation, state- and trait-based RNT, and general depression. Baseline and follow-up alcohol intake showed minimal relevance in explaining hangover anxiety severity. Lasso regression also selected state-based emotion dysregulation and general anxiety as relevant explanatory factors.ConclusionsVariables most strongly associated with hangover anxiety were state-based emotion dysregulation, illness-related depression, and general anxiety. The role of illness-related depression may reflect underlying inflammation or unique psychological mechanisms. State-based emotion dysregulation and inflammation emerged as relevant factors warranting additional study in the context of hangover anxiety intervention development. Additionally, findings underscore the higher probability of hangover anxiety among individuals with elevated general anxiety.”

   General and hangover-related depressive and anxiety symptoms: Implications for drinking behaviors and consequences

   DalSpace (Dalhousie University) (Kim)Published Jul 20, 2026Checked Oct 14, 2026

   “Study 4, using a cross-sectional design (N = 5111 international university students), compared hangover-sensitive (n = 3205) and hangover-resistant (n = 1906) drinkers on depressive, anxiety, and stress symptoms. Differences in anxiety and stress were statistically significant but not clinically meaningful, suggesting negative emotions do not explain individual differences in hangover susceptibility and are unlikely to confound its relationship with subsequent drinking outcomes. Overall, dissertation findings suggest that hangover-sensitive individuals engage in HED to cope with depressive symptoms, leading to hangover-related depression and rumination that, in turn, lead to more coping-motivated HED by intensifying mood disturbances and stress (via alcohol-related problems). These findings add to the alcohol literature by identifying hangover-related depression and rumination as possible maintaining mechanisms in a negative reinforcement cycle that raises AUD risk, and by advancing the measurement of these hangover constructs.”

   The Impacts of Binge Drinking and Hangover on the Social Brain: An Integrative Narrative Review.

   Biomedicines (Bagosi et al.)Published Nov 17, 2025Checked Oct 14, 2026

   “This is an integrative narrative review synthesizing human studies and animal models of binge drinking (also known as alcohol intoxication) and hangover (also known as alcohol withdrawal). The major databases consulted were PubMed, Scopus, and Web of Science. The search terms used were "binge drinking" or "hangover"and "social behavior" or "social brain" in combination with "rats", "mice" or "humans". Finding the missing link between structural and functional changes in the social brain in the context of binge drinking and hangover is crucial for developing novel therapeutic strategies for alcohol intoxication and withdrawal. This review focuses on changes in hypothalamic neurohormones and extrahypothalamic neurotransmitters in these states, and concludes with the statement that targeting neuropeptides such as corticotropin-releasing hormone (CRH) and arginine vasopressin (AVP) and their receptors, which are involved in both binge drinking and social behavior, may prevent repeated cycles of binge drinking and hangover from spiraling into alcohol addiction and, ultimately, social isolation.”
