   Hangover (Wikipedia)

   WikipediaPublished Oct 9, 2026Checked Oct 10, 2026

   “A hangover is the experience of various unpleasant physiological and psychological effects usually following the consumption of alcohol. Hangovers can last for several hours or for more than 24 hours. Typical symptoms of a hangover may include headache, drowsiness, weakness, concentration problems, dry mouth, dizziness, fatigue, muscle ache, gastrointestinal distress (e.g., nausea, vomiting, diarrhea), loss of appetite, light sensitivity, depression, sweating, hyper-excitability, high blood pressure, irritability, and anxiety. While the causes of a hangover are still poorly understood, several factors are known to be involved including acetaldehyde accumulation, changes in the immune system and glucose metabolism, dehydration, metabolic acidosis, disturbed prostaglandin synthesis, increased cardiac output, vasodilation, sleep deprivation, and malnutrition. Beverage-specific effects of additives or by-products such as congeners in alcoholic beverages also play an important role. The symptoms usually occur after the intoxicating effect of the alcohol begins to wear off, generally the morning after a night of heavy drinking.”

   “Searches were performed in MEDLINE, Embase, PsycNET, Scopus and CINAHL from inception to January 2025. Two independent reviewers screened articles, assessed the risk of bias and extracted data.Key findingsTwenty-two studies (n = 6152; mean age 26.9 years, 57% female) demonstrated a significant association between hangovers and increased negative affect, including anxiety, stress and depression. Maladaptive emotional regulation, avoidant coping styles, repetitive negative thinking and greater baseline anxiety exacerbated these negative experiences, while social support and mental resilience offered potential protective factors.ImplicationsThe findings highlight the clinical importance of addressing psychological factors in alcohol-related harm. The tendency to return to binge drinking despite negative hangover experiences suggests that psychological factors may perpetuate unhealthy alcohol consumption.ConclusionThis review supports a strong link between alcohol hangovers and heightened negative affect. Effective interventions must address both the reduction of negative affect and the underlying drivers of binge drinking to promote healthier alcohol consumption patterns.”

   Will I Have a Hangover Headache Tomorrow? A Prospective Cohort Study of the Predictors of Delayed Alcohol-Induced Headache.

   Life (Basel, Switzerland) (García-Azorín et al.)Published Nov 7, 2025Checked Oct 10, 2026

   “We aimed to evaluate the factors associated with the presence of a headache as a hangover symptom.MethodsThis was a prospective cohort study, including 32 healthy individuals who voluntarily consumed alcohol and completed self-administered questionnaires during three separate alcohol consumption and hangover episodes.ResultsA headache was a hangover symptom in 55/96 (57.3%) episodes. The phenotype was predominantly holocranial (94.5%), frontal (98.2%), and pressing (67.2%), with a median intensity of 6 (IQR 4-8). Headaches worsened with physical activity (100%) and had orthostatic changes (89.1%). A prior history of headaches was associated with headache occurrence (odds ratio: 3.480; 95% confidence interval (CI): 1.084 to 11.177), and headache precipitation by standing up was associated with a shorter duration (hazard ratio: 0.257; 95% CI: 0.073 to 0.901).ConclusionsDelayed alcohol-induced headaches had a migraine-like phenotype. An orthostatic pattern suggestive of a low cerebrospinal fluid pressure was associated with a shorter duration of the headache.”

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

   Biomedicines (Bagosi et al.)Published Nov 17, 2025Checked Oct 10, 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.”
