Waking up with a pounding head and queasy stomach often leads to one big question—how long does a hangover usually last?
A hangover happens when your body reacts to drinking alcohol, creating a mix of headache, fatigue, dry mouth, nausea, and sensitivity to light and sound. It’s your body’s response to dehydration, low blood sugar, and the toxic byproducts formed as your liver breaks down alcohol.
Most hangovers pass within a day, but how long they linger depends on how much alcohol you consumed, what you drank, and how well your body processes alcohol. Understanding this timeline and what makes recovery faster—can help you plan better nights out and easier mornings after.
How Long Does a Hangover Usually Last?
Research from the Alcohol Hangover Research Group defines a hangover as a set of symptoms that develop when blood alcohol concentration (BAC) falls significantly and peaks when it returns to nearly zero. According to their consensus statement, hangovers can last up to about 24 hours after drinking, depending on several factors such as how much alcohol was consumed and individual alcohol metabolism (Verster et al., 2010).
During this time, people may experience symptoms such as headache, fatigue, thirst, nausea, and difficulty concentrating as the body continues to metabolize alcohol and restore normal function. The duration and intensity can vary from person to person, but these effects typically lessen as blood alcohol levels stabilize and hydration is restored.
What Affects the Length of a Hangover?
Several factors influence how long unpleasant symptoms last. Your drinking habits, hydration levels, and even your age play key roles in how the body recovers after consuming alcohol.
How Much You Drank
The more alcohol you drink, the longer your body needs to metabolize it. Heavy or excessive drinking leads to higher blood alcohol concentration, more toxic byproducts, and stronger inflammation, all of which extend recovery time.
Drinking on an Empty Stomach
Drinking on an empty stomach causes alcohol to absorb faster through the gastrointestinal tract, leading to higher peaks in blood alcohol levels. Eating beforehand slows absorption and reduces how long symptoms linger.
Sleep Quality
Poor sleep after drinking leaves your body more fatigued and worsens headaches, dizziness, and irritability. Getting enough sleep allows the body to restore energy and may help you feel better while recovering.
Hydration Levels
Alcohol increases urine output, which can contribute to dehydration and symptoms like thirst and dry mouth. Replacing fluids and electrolytes with plain water, sports drinks, or fruit juice helps your body recover more efficiently.
Age and Metabolism
Some research suggests that age-related changes in body composition and liver efficiency may affect how alcohol is processed. The liver processes alcohol more slowly, and dehydration can happen faster. These changes make hangovers feel stronger and last longer.
Alcohol Type
Darker-colored drinks like red wine, whiskey, and malt liquor contain more congeners—natural byproducts of fermentation that some studies link to stronger hangover symptoms. Lighter beverages like vodka or white wine may cause fewer lingering effects for some people.
What Are Common Hangover Symptoms?
The discomfort of a hangover goes beyond a simple headache. It often affects both the body and mind as alcohol disrupts normal chemical balance and sleep patterns.
Physical Symptoms
Common physical signs include nausea, fatigue, muscle aches, upset stomach, dry mouth, and rapid heartbeat. These occur as alcohol irritates the stomach lining, lowers blood sugar, and dehydrates tissues.
Mental Symptoms
Mentally, you may feel brain fog, irritability, or poor focus. Alcohol interferes with neurotransmitters that affect mood and coordination, leaving you groggy and slow to think clearly.
How to Support Recovery and Feel Better
While there’s no single hangover cure, a few science-based habits can help your body recover faster and feel more balanced.
Rehydrate With Water and Electrolytes
Drink plenty of water throughout the day and add electrolyte drinks or mineral-rich fruit juice to replace sodium, potassium, and magnesium lost through increased urination. Staying hydrated replaces fluids lost through drinking and may help you feel more comfortable as you recover.
Eat Nutritious Foods
Eating balanced meals helps maintain steady energy and provides nutrients the body uses while processing alcohol. Choose bland foods like toast, oatmeal, or a greasy breakfast only if your stomach can handle it—healthy carbohydrates and protein are better for steady energy.
Rest and Sleep
Sleep gives your body time to continue metabolizing alcohol and restore normal function, which can make symptoms feel less intense, such as fatigue and muscle soreness.
Fresh Air and Gentle Movement
A short walk, stretch, or light exercise improves circulation and oxygen delivery. Gentle movement may help relieve tension and improve circulation as your body recovers from drinking.
Consider Supportive Supplements
Adults who drink responsibly may benefit from nutrients that help maintain overall wellness. Drinkwel is a multivitamin that includes ingredients such as milk thistle, artichoke, and schisandra, which have been studied for their potential roles in supporting nutrient metabolism and hydration. LyteShow provides electrolytes like magnesium, potassium, and sodium that help maintain normal fluid levels. Both are formulated to complement a balanced diet and a responsible lifestyle, not replace them.
For those seeking hydration without added sugars or artificial ingredients, LyteShow also comes as a liquid electrolyte concentrate. Each serving provides magnesium, sodium, chloride, potassium, and zinc—trace minerals and electrolytes that help the body sustain normal fluid function. When mixed with water, it forms an isotonic beverage suitable for rehydration after exercise, sweating, or occasional alcohol use.
Individuals with health conditions or who take other medications should consult a healthcare professional before use.
Can You Shorten How Long a Hangover Lasts?
According to the National Institute on Alcohol Abuse and Alcoholism, there is no proven way to shorten or cure a hangover. The body simply needs time to finish metabolizing alcohol, clear the toxic byproducts, and restore normal hydration and function. Remedies often mentioned online, like coffee, showers, or drinking more alcohol, may offer temporary relief but do not speed recovery (NIAAA, 2021).
You can, however, make hangover discomfort easier to manage by:
-
Drinking water or electrolyte beverages to help replace fluids lost through urination.
-
Eating balanced meals that include carbohydrates, protein, and micronutrients to support energy levels.
-
Getting adequate rest, which allows the body to complete its recovery naturally.
-
Drinking in moderation or spacing out alcoholic drinks to reduce the risk of severe hangovers.
-
Avoiding the “hair of the dog” approach, which means drinking more alcohol the next morning to feel better. While it might dull symptoms temporarily, it can actually delay recovery and increase dehydration.
Hangover symptoms fade as the body completes its natural recovery process, though the exact duration varies from person to person.
Hangovers Usually Fade Within a Day, but You Can Support Recovery
Most hangovers clear within 8 to 24 hours, though the experience varies depending on how much alcohol you drink, your hydration, sleep quality, and the type of beverage consumed. Research shows that only time allows the body to fully process alcohol and restore its natural equilibrium. While hydration, nourishing meals, and rest can make recovery more comfortable, they do not shorten the duration.
For adults who drink responsibly, products like Drinkwel, formulated with vitamins and botanicals studied for their roles in nutrient support and hydration, and LyteShow, which provides electrolytes that help maintain normal fluid levels, can complement a healthy lifestyle. Both are meant to fit into a mindful approach to wellness that emphasizes moderation, nutrition, and self-care—the most reliable ways to support recovery after drinking.
