The idea that a glass of milk can magically erase the effects of a night of drinking is a popular, yet misleading, health myth. While consuming milk might make you feel temporarily better, it does not address the root causes of a hangover. The discomfort you feel is a complex combination of dehydration, inflammation, and metabolic disturbances, none of which milk can effectively resolve.
What Really Happens During a Hangover
A hangover is more than just a bad headache. It's the body's response to alcohol's toxic effects, which include:
- Dehydration and electrolyte imbalance: Alcohol is a diuretic, causing increased urination and leading to a significant loss of fluids and essential electrolytes like potassium and sodium.
- Gastrointestinal irritation: Alcohol inflames the lining of the stomach and intestines, leading to the nausea, vomiting, and stomach pain often associated with hangovers.
- Acetaldehyde exposure: As the liver processes alcohol, it produces a toxic compound called acetaldehyde, which is responsible for many of the unpleasant symptoms.
- Sleep disruption: Although alcohol can make you feel sleepy, it fragments your sleep cycles, leading to poor-quality sleep and leaving you tired and groggy the next day.
- Blood sugar fluctuations: The body's processing of alcohol can lead to a drop in blood sugar, contributing to fatigue and headaches.
The Limited Role of Milk in Hangover Relief
So why do some people report feeling better after drinking milk? The relief is largely symptomatic and superficial. Milk may provide comfort in a few minor ways, but it is not a cure.
Milk's effects on hangover symptoms
- Provides hydration: Milk is a fluid, and any fluid intake helps counteract the dehydration caused by alcohol. This is the most significant benefit, but plain water or an electrolyte drink is more effective for this purpose.
- Coats the stomach: Some people believe milk can "line the stomach" and protect it from irritation. While this is not biologically accurate—the stomach has no such lining—the fats and proteins in milk can slow down stomach emptying and coat the stomach's lining, providing a temporary soothing sensation against the alcohol-induced inflammation. This does not, however, stop the absorption of alcohol.
- Replenishes some nutrients: Milk contains some electrolytes, such as potassium, and can offer a slight boost in blood sugar, which might help with low energy levels. However, the amounts are often not substantial enough to make a major difference.
Comparison Table: Milk vs. Proven Remedies
| Feature | Milk's Effect | Proven Remedies (Water, Sleep, Electrolytes) | Why It Works Better |
|---|---|---|---|
| Addresses Dehydration? | Mildly, through fluid content. | Directly and effectively rehydrates the body and replaces lost minerals. | Higher electrolyte concentration and purpose-built formula. |
| Soothes Stomach? | Temporarily masks irritation by coating the lining. | Antacids can neutralize stomach acid; bland foods don't exacerbate irritation. | Directly targets the source of stomach upset. |
| Eliminates Toxins? | No significant effect on the liver's metabolism of acetaldehyde. | Time is the only cure, allowing the liver to process toxins naturally. | The body's metabolic process is the only way to remove toxins. |
| Boosts Energy? | Provides some protein and sugar. | Bland, carb-rich foods and rest stabilize blood sugar and combat fatigue. | Provides more efficient and sustained energy boosts. |
| Speeds Recovery? | Does not speed up recovery time. | Rest and hydration allow the body to recover at its natural pace. | The body needs time; no external substance can significantly speed it up. |
How to Actually Cure a Hangover
Since milk provides only limited, superficial relief, a holistic approach is best for recovery. The most effective strategies involve hydration, nutrition, and rest.

A Better Approach to Hangover Relief
- Rehydrate effectively: Drink plenty of water throughout the day. For severe dehydration, use electrolyte-fortified drinks like sports drinks or broth to restore minerals.
- Eat bland foods: A meal of toast, crackers, or bouillon soup can settle your stomach and help restore blood sugar levels without causing further irritation.
- Get proper rest: Sleep is the only thing that truly allows your body to recover from the stress of excessive alcohol consumption.
- Use pain relievers cautiously: Over-the-counter pain relievers can help with headaches, but avoid acetaminophen (Tylenol), as it can be toxic to the liver when combined with alcohol. Ibuprofen can irritate the stomach, so use it sparingly.
Conclusion: The Final Verdict
Ultimately, the sensation that milk might "cure" a hangover is a pleasant, but ultimately false, belief rooted in temporary relief. While milk can help rehydrate the body and soothe an irritated stomach, these effects are minor compared to the true causes of a hangover. The body needs time and targeted support to recover from dehydration, inflammation, and toxic byproducts. The best advice remains to prevent hangovers in the first place through responsible drinking practices, and rely on proven methods of hydration and rest when recovery is needed.
