You crushed a night out—but your body is paying the price. The dreaded hangover isn’t just “feeling rough”; it’s a complex physiological state driven by toxic metabolites, immune activation, disrupted glucose and electrolyte homeostasis, sleep disruption, and more. At its core, a hangover represents the body’s response to acute ethanol exposure as blood alcohol concentration returns to zero, triggering systemic inflammation, gastrointestinal irritation, and neurochemical imbalance.

Why Hangovers Happen
Alcohol is metabolised primarily in the liver to acetaldehyde, a toxic intermediate compound far more harmful than ethanol itself, contributing to nausea, headache, and malaise. Alcohol also increases urine output by suppressing antidiuretic hormone, leading to fluid and electrolyte losses that can worsen symptoms. Smithsonian Magazine Beyond toxins, elevated pro-inflammatory cytokines correspond with hangover severity, linking immune responses to both physical and cognitive symptoms. OUP Academic
Prevalence and Demographics
Studies show a large majority of social drinkers report at least one hangover symptom after heavy drinking episodes, with one controlled investigation noting 78 per cent prevalence of hangover symptoms after alcohol exposure. ScienceDirect Epidemiological surveys find frequent hangovers correlate with heavier consumption patterns and are most common among young adults. Males often report more frequent hangovers, largely explained by higher intake levels.

Nutrition and Hangover: Evidence-Based Insight
Emerging research underscores the role of nutrients in modulating hangover severity. In an experimental study, individuals with higher dietary intake of nicotinic acid (vitamin B3) and zinc reported significantly lower hangover severity, suggesting these micronutrients may support ethanol and acetaldehyde metabolism.

Optimising Recovery Through Nutrition
Strategic nutrition supports metabolic recovery and mitigates symptom burden:
Electrolytes (potassium, magnesium) to address alcohol-induced losses
Complex carbohydrates to stabilise blood glucose
Protein and B vitamins for hepatic detoxification support
Antioxidants to improve liver clearance and reduce oxidative stress that contributes to inflammation. This may present as headaches, nausea, and fatigue. Oranges, berries, N-acetylcysteine (NAC) and pineapple (also contains bromelain which helps reduce inflammation) are great sources of antioxidants.
While water alone has limited impact on hangover severity, combined nutritional support can improve overall recovery. ScienceDirect
Conclusion
Hangovers reflect more than a “rough morning”—they are a measurable physiological stress state. Nutrition and metabolic support should be central to recovery strategies.
