Hangovers affect about 70-75% of people who drink heavily, causing symptoms like headache, nausea, fatigue, and dehydration1 . These symptoms result from alcohol’s toxic effects, its metabolite acetaldehyde, and disruptions in sleep and biological rhythms2 3. While there is no definitive cure for hangovers, effective management focuses on hydration, rest, and symptom relief without further alcohol intake3 4.
Rehydrate with Water and Electrolytes
Alcohol acts as a diuretic, increasing urine production and leading to dehydration, which contributes to common hangover symptoms such as dry mouth, headache, and dizziness5 6. Rehydrating with water and electrolyte-rich fluids is essential to restore fluid balance and replenish lost salts like sodium and potassium3 7. Electrolyte solutions and broths can be more effective than water alone in correcting imbalances caused by alcohol consumption7 5.
Drinking more alcohol to relieve a hangover, often called "hair of the dog," is counterproductive because it prolongs the presence of toxic substances like acetaldehyde in the body and delays recovery3 6. The body requires time to metabolize and eliminate alcohol and its metabolites to fully recover3 .
Tips for effective rehydration:
- Drink plenty of water throughout the day to combat dehydration3 4.
- Include electrolyte drinks or broths to replace lost minerals7 5.
- Avoid alcoholic beverages as a remedy, since they worsen hangover symptoms3 6.
- Sip fluids slowly to prevent nausea8 .
- Monitor for signs of severe dehydration that may require medical attention4 .
Alcohol’s diuretic effect causes dehydration, which is a key factor in hangover symptoms like headache and fatigue. Rehydration with water and electrolytes supports recovery by restoring fluid and mineral balance5 6.
Choose Caffeine-Free Beverages
While many people reach for coffee or caffeinated drinks to combat hangover fatigue, caffeine does not reduce blood alcohol concentration or speed up alcohol elimination9 103. Moreover, caffeine can increase blood pressure, which may already be elevated due to alcohol consumption, potentially worsening symptoms like headache11 12.
Instead, caffeine-free beverages such as water, fruit juices, and electrolyte solutions are recommended to aid hydration and alleviate hangover symptoms3 8. These drinks help restore blood sugar levels and replenish fluids without the side effects associated with caffeine.
Benefits of caffeine-free drinks:
- Promote better hydration without increasing blood pressure3 8.
- Help restore electrolyte and sugar balance3 8.
- Avoid masking symptoms that caffeine might temporarily relieve but not cure3 .
- Reduce risk of gastrointestinal irritation linked to caffeine3 .
- Support overall symptom relief more effectively than caffeinated beverages3 .
Coffee may temporarily reduce grogginess but does not improve hangover severity or alcohol metabolism, and it can worsen headaches by raising blood pressure11 3.
Eat a Light, Nourishing Meal
Eating a non-greasy, light breakfast can help restore blood sugar levels and provide essential nutrients to support recovery3 8. Alcohol consumption lowers blood sugar, which contributes to symptoms such as weakness, dizziness, and fatigue13 5. Consuming bland foods rich in complex carbohydrates, such as toast, crackers, bananas, rice, and applesauce, can help stabilize blood sugar and soothe an irritated stomach3 86.
Greasy or heavy foods may exacerbate heartburn and stomach discomfort caused by alcohol’s irritating effects on the gastrointestinal tract3 . A balanced meal containing protein, fats, and carbohydrates before drinking can reduce peak blood alcohol levels and potentially lessen hangover severity3 .
Recommended foods for hangover relief:
- Toast, crackers, or whole-grain cereals to boost blood sugar3 8.
- Bananas and fruits to provide vitamins and potassium3 7.
- Rice or plain noodles for easy digestion3 .
- Broth or soup to replenish salts and fluids7 .
- Avoid greasy, spicy, or heavy meals that may worsen nausea or heartburn3 .
Eating bland foods with complex carbohydrates helps raise blood sugar and settle the stomach, which can reduce nausea and fatigue during a hangover6 8.
Consider Alka-Seltzer for Symptom Relief
Alka-Seltzer, an over-the-counter antacid and pain reliever, may help alleviate some hangover symptoms such as stomach discomfort and headache3 . Alcohol increases gastric acid secretion, which can cause gastritis symptoms including stomach pain and nausea3 . Antacids like sodium bicarbonate in Alka-Seltzer neutralize stomach acid and may relieve these symptoms3 .
However, caution is advised when using medications during a hangover, especially those containing aspirin or other NSAIDs, as they can irritate an already sensitive stomach3 . Consulting a healthcare professional before use is recommended.
Key points about Alka-Seltzer use:
- Neutralizes excess stomach acid to reduce heartburn and nausea3 .
- May provide temporary relief from headache and muscle aches3 .
- Should be used cautiously to avoid gastric irritation3 .
- Not a cure but can support symptom management3 .
- Consult a healthcare provider if symptoms persist or worsen3 .
Select Appropriate Pain Relief Medication
Pain relievers such as aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) can reduce headache and muscle aches associated with hangovers3 6. However, alcohol consumption increases gastric acid secretion and can cause gastritis, making the stomach more vulnerable to irritation from NSAIDs3 . Therefore, these medications should be used sparingly and with caution.
Acetaminophen (paracetamol) is generally not recommended during hangovers because it can cause liver damage, especially when alcohol is still present in the body3 6. Medical advice is strongly advised before taking any medication to treat hangover symptoms.
Guidelines for pain relief during hangover:
- Use NSAIDs like aspirin or ibuprofen cautiously to avoid stomach irritation3 6.
- Avoid acetaminophen due to potential liver toxicity when combined with alcohol3 6.
- Take the lowest effective dose for the shortest duration3 .
- Consult a healthcare professional if you have underlying liver or stomach conditions3 .
- Consider antacids alongside NSAIDs to protect the stomach lining3 .
Rest or Engage in Gentle Activity
Rest is a fundamental part of hangover recovery, allowing the body to metabolize and eliminate alcohol and its toxic byproducts3 4. Adequate rest helps alleviate fatigue and supports metabolic recovery3 . Light exercise may be beneficial if hydration and nutrition are adequate, as it can improve circulation and mood3 .
However, heavy or intense exercise during a hangover can worsen dehydration and fatigue, potentially prolonging recovery3 . It is important to listen to your body and avoid overexertion.
Recommendations for activity during hangover:
- Prioritize rest and avoid strenuous physical activity3 4.
- Engage in light exercise such as walking if feeling up to it and well-hydrated3 .
- Monitor hydration status closely during any activity3 .
- Use rest periods to support cognitive and physical recovery3 .
- Seek medical advice if symptoms are severe or persistent3 .
“If someone found a cure for a hangover, they'd be very wealthy. People have looked at a lot of things to prevent a hangover or treat the symptoms, but nothing has really stood out.”
— Kapil Sachdeva, Northwestern Medicine5
Prioritize Quality Sleep
Alcohol disrupts normal sleep architecture, reducing the amount of restorative deep sleep and causing frequent awakenings during the night3 8. This poor-quality sleep exacerbates hangover symptoms such as fatigue, cognitive impairment, and mood disturbances3 . Getting sufficient sleep after drinking supports the body's metabolic recovery and symptom relief3 4.
“One may wonder whether a remedy is needed at all. It's your body's way of saying you shouldn't be drinking that much and without that signal, it could lead to problems down the road, such as paving the way to addiction.”
— Kapil Sachdeva, Northwestern Medicine5
Since alcohol withdrawal during sleep leads to fragmented rest, allowing extra time for sleep can help mitigate these effects3 . Avoiding alcohol before bedtime is the best way to preserve sleep quality.
Sleep tips for hangover recovery:
- Aim for extended sleep duration to compensate for disrupted sleep cycles3 .
- Create a calm, dark, and quiet environment to enhance sleep quality3 .
- Avoid caffeine and other stimulants before bedtime3 .
- Use relaxation techniques if needed to improve sleep onset3 .
- Recognize that sleep is a key factor in reducing hangover severity3 .
Alcohol disrupts the hormones regulating biological clocks and sleep stages, leading to poor restorative sleep and worsening hangover symptoms like fatigue and impaired cognition3 .
