How to Treat a Hangover at Home

Understanding What Happens to Your Body During a Hangover

A hangover is a collection of physical symptoms that occur after drinking alcohol. The main culprit behind hangovers is dehydration—alcohol is a diuretic, meaning it causes your body to lose more water than usual. When you drink alcohol, your kidneys work harder to filter it out, and you urinate more frequently. This fluid loss affects your blood volume and can lead to headaches, dizziness, and fatigue.

Alcohol also disrupts your sleep patterns. While alcohol might make you feel drowsy initially, it interferes with REM (rapid eye movement) sleep, the restorative stage where your brain consolidates memories and your body recovers. This is why you might sleep for eight hours after drinking but still wake up exhausted. Your body hasn't actually rested properly.

Additionally, alcohol causes your blood sugar to drop. Your liver normally maintains steady blood glucose levels, but alcohol interferes with this process. Low blood sugar contributes to the shakiness, weakness, and mood changes many people experience the morning after drinking.

Congeners—compounds in alcoholic beverages beyond pure ethanol—also play a role. Dark liquors like whiskey, red wine, and brandy contain more congeners than clear spirits like vodka or gin. Some research suggests congeners may intensify hangovers, though the primary factor is still the total amount of alcohol consumed.

Practical takeaway: Recognizing that dehydration, poor sleep, low blood sugar, and toxic byproducts all contribute to hangovers helps you understand why the treatment involves addressing multiple issues, not just one solution.

Rehydration and Electrolyte Replacement Strategies

The most effective hangover remedy is rehydration. Since dehydration is the primary cause of hangover symptoms, replacing lost fluids should be your first priority. Water is your best option—it's free, accessible, and directly addresses the core problem. Drink water consistently throughout your recovery period, not all at once. Drinking large amounts of water too quickly can cause nausea and actually worsen how you feel temporarily.

Along with water, consider beverages that contain electrolytes—sodium, potassium, and magnesium. These minerals help your body absorb and retain fluids more effectively than water alone. Sports drinks designed for athletes, such as those containing 6-8% carbohydrates and electrolytes, can be beneficial. Coconut water is another natural option that contains potassium and some sodium. If you don't have access to commercial products, you can make a simple electrolyte solution at home by mixing one liter of water with six teaspoons of sugar and one-half teaspoon of salt.

Broth-based soups provide both fluid and sodium in a comforting form. The warm liquid is often easier on an upset stomach than cold beverages, and the salt helps your body retain the fluids you're consuming. Bone broth, vegetable broth, or simple chicken broth all work well. The sodium content also addresses the electrolyte loss that occurred during drinking.

Avoid or limit caffeinated beverages like coffee and tea during the early stages of hangover recovery. Caffeine is also a diuretic, meaning it increases urination and can worsen dehydration. Similarly, avoid sugary drinks, energy drinks with excessive caffeine, and alcohol itself. While "hair of the dog" (drinking more alcohol) might provide temporary relief, it only delays the hangover and compounds the problem.

Practical takeaway: Start your recovery by sipping water regularly and including at least one electrolyte-containing beverage. This single step addresses the root cause of most hangover symptoms and should be your foundation for treatment.

Nutrition and Blood Sugar Management

Once you can tolerate food, eating the right nutrients becomes important. Your blood sugar is depleted after a night of drinking, and restoring it helps with energy levels, mood, and mental clarity. Focus on foods containing complex carbohydrates and protein, which are digested more slowly and provide sustained energy rather than quick spikes followed by crashes.

Toast with eggs, oatmeal with fruit, whole grain cereal with milk, or whole wheat pasta with vegetables are all appropriate choices. These foods combine carbohydrates for quick energy and protein for lasting satisfaction. Bananas are particularly beneficial because they contain potassium, an electrolyte your body lost through increased urination. They're also gentle on the stomach and easy to digest.

Ginger has been studied for its effects on nausea and can be consumed in several ways—fresh ginger tea, ginger ale, or candied ginger. While research on ginger's hangover-specific benefits is limited, it's been shown in other contexts to reduce nausea and may help you feel well enough to eat other recovery foods. Peppermint tea serves a similar purpose and may soothe stomach upset.

Fatty and greasy foods might seem appealing but can worsen nausea and stomach discomfort. Avoid fried foods, heavy creams, and spicy dishes until you've fully recovered. Similarly, citrus fruits and tomato-based foods can irritate an already-sensitive stomach. Once your appetite returns fully, you can gradually return to normal eating patterns.

Avoid skipping meals. Some people feel too nauseous to eat, but consuming small amounts of bland, nutritious food actually helps stabilize blood sugar and accelerates recovery. If solid food seems impossible, a smoothie made with yogurt, banana, and honey provides calories, protein, and carbohydrates in liquid form that's easier to tolerate.

Practical takeaway: Eat small portions of bland, carbohydrate and protein-rich foods to stabilize your blood sugar. Include a banana for potassium and ginger or peppermint for nausea relief.

Rest, Sleep, and Physical Recovery

Your body has work to do during hangover recovery. Sleep and rest are where most of this recovery happens. While the alcohol interrupted your sleep quality the night before, allowing yourself additional sleep the next day helps your body recover. Don't schedule demanding activities or important tasks on the day after heavy drinking if possible. Give yourself permission to rest without guilt.

If you can't sleep more, simply resting in a quiet, dark environment supports recovery. Darkness triggers melatonin production, the hormone that regulates sleep-wake cycles. A dark bedroom or blackout curtains can help, even if you're just resting rather than sleeping. Quiet environments reduce stress on your nervous system, which is already taxed from processing alcohol.

Gentle, light movement can actually help some people feel better, though intense exercise should be avoided. A short walk outside in daylight can help restore your circadian rhythm, which was disrupted by drinking. Exposure to natural light helps regulate your sleep-wake cycle. However, avoid strenuous exercise, heavy lifting, or intense workouts while recovering. Your body is dealing with inflammation and dehydration, and intense physical activity increases stress on your system.

Temperature regulation matters too. Some people find cool compresses on the forehead helpful for headaches. A cool, comfortable room temperature is better than excessive heat, which can increase fluid loss through sweating. If you have a headache, lying down in a cool, dark, quiet room often provides relief without medication.

Nausea is common with hangovers. If you experience nausea, try the BRAT diet—bananas, rice, applesauce, and toast. These bland foods are less likely to trigger vomiting. Avoid lying flat, which can worsen nausea; instead, sit upright or recline at a slight angle. Ginger supplements or tea can reduce nausea for some people.

Practical takeaway: Prioritize rest and sleep, maintain a cool and dark environment, and engage only in gentle movement. Allow your body time to recover rather than pushing through the day normally.

Over-the-Counter Medications and Supplements

Several over-the-counter options may provide symptom relief, though they don't cure a hangover. Pain relievers can address headaches and body aches. Acetaminophen and ibuprofen are both used for hangover symptoms, but they work differently. Ibuprofen is an anti-inflammatory and may be slightly more effective for hangover-related discomfort. However, taking acetaminophen with alcohol in your system or shortly after drinking can stress your liver, so some medical professionals recommend avoiding
