What was done
A pre-registered systematic review adhering to PRISMA and Synthesis Without Meta-analysis (SWiM) guidelines was conducted to evaluate the link between alcohol hangovers and negative affect. Searches spanned MEDLINE, Embase, PsycNET, Scopus, and CINAHL from inception to January 2025. Two independent reviewers screened articles, assessed risk of bias, and extracted data.
What was found
Twenty-two studies were identified, including 6,152 participants (mean age 26.9 years, 57% female). The synthesis demonstrated a significant association between alcohol hangovers and heightened negative affect, including anxiety, stress, and depression. Factors that exacerbated these symptoms included maladaptive emotional regulation, avoidant coping styles, repetitive negative thinking, and elevated baseline anxiety, whereas social support and mental resilience acted as protective factors. Specific effect sizes and numerical estimates were not reported in the abstract.
Why it matters
This review establishes that psychological distress is a consistent component of the alcohol hangover state, highlighting emotional factors that may sustain recurrent binge drinking cycles.
Limits
The abstract provides no quantitative effect estimates or meta-analytic pooling. The study population skews young (mean age ~27), limiting generalizability to older cohorts. Specific study designs, measurement tools, and risk-of-bias results are not detailed in the abstract.
