Symptoms Treatment Prevention Frequently Asked Questions A Word From Verywell If you've ever woken up with a bad hangover headache, most likely the first thing you wanted to do was figure out how to get rid of it as soon as possible. Unfortunately, the only reliable cure for a hangover is time, but there are things you can do to make the symptoms less unpleasant as you ride it out. Understanding what causes a hangover headache can help you take steps to mitigate the symptoms, plus give you a heads-up on how to avoid another one in the future. Martin Dimitrov / Getty Images What Is a Hangover Headache? A hangover headache—also called a delayed alcohol-induced headache—usually comes on the morning after drinking the night before, once the alcohol is out of the your system. A hangover usually lasts for around 24 hours. According to a survey done by the National Headache Foundation, 92% of the population has experienced a hangover headache at some point in their lives. Consuming alcohol can also trigger an underlying primary headache disorder. So if you already experience migraines, cluster headaches, or tension-type headaches, drinking alcohol may precipitate your usual headache attack. Scientists are not certain as to what causes hangovers, but there are several theories. Some potential causes include dehydration, the direct effect of alcohol on the brain, the withdrawal of alcohol, alcohol additives, alterations in the body's hormones, and the effects of acetaldehyde, which is a product of alcohol metabolism. In addition, some people may be born with a genetic predisposition to developing worse hangovers than others. Dehydration occurs because alcohol inhibits the effect of a hormone called antidiuretic hormone (ADH). Normally, ADH stimulates the kidneys to reabsorb water from urine to prevent dehydration. But by inhibiting ADH, water is instead urinated out at a faster rate than you're adding fluids back. But, while hydration can help ease a hangover, it does not completely alleviate the symptoms. Drinking dark liquors (such as whiskey) tends to lead to more severe hangovers due to by-products called congeners in the drinks. Symptoms Hangovers vary in severity and symptoms from person to person and episode to episode. Hangover headaches tend to: Occur on both sides of the head Be located on the forehead and/or the temples. PulsateWorsen with physical activity In addition to a headache, other common symptoms of a hangover include: DiarrheaLoss of appetiteFatigueNauseaDizzinessFast heart rateSweatingReduced attention and concentrationLow or anxious moodGeneral feeling of unwellness Treatment If you have a hangover, it will take time for the headache to completely go away, but there are certain measures you can take to relieve its severity. Self Care Having a hangover is exhausting, so getting as much rest as possible is important to restore your energy and well-being. Other things you can do to help yourself feel better include avoiding smoking and putting a cold compress on your head if it relieves your headache. Medication Taking an over-the-counter nonsteroidal anti-inflammatory (NSAID) like Advil (ibuprofen) can usually ease a hangover headache, but be sure take an NSAID with food, as it may upset your stomach. Also, some people cannot take NSAIDs due to underlying medical problems, so be sure it is safe for you. Keep in mind that it is important to minimize the use of Tylenol (acetaminophen) when drinking alcohol (or recovering from a hangover), as the combination can harm the liver. Nutrition The most important thing to consume while you are recovering from a hangover is liquids to avoid further dehydration. Any liquid (except alcohol!) that you find palatable is acceptable, such as boullion, chicken soup, sports drinks, or water. Fruit juices can also help boost your blood sugar. If you're feeling queasy, avoid rich, greasy foods and stick to dry, bland foods like toast and crackers. While certain supplements and herbal remedies have been touted as hangover remedies, there is no solid evidence backing up this claim. Prevention The only guaranteed way to prevent a hangover headache is to avoid alcohol, or at least drink in moderation. For healthy adults, moderate drinking means up to one drink a day for women of all ages and two drinks a day for men. A "drink" in this case is considered a 5-ounce glass of wine or 12 ounces of beer. If you are going to drink, here are some tips for lessening the effect of alcohol: Eat before and while drinking. As alcohol is absorbed more quickly if your stomach is empty, eating something may help slow down its effects.Choose carefully. Beverages with fewer congeners are slightly less likely to cause hangovers than beverages with more congeners, but remember that all types of alcohol can result in a hangover.Sip water between drinks. Drinking a full glass of water after each alcoholic drink will help you stay hydrated. It'll also help you drink less alcohol.Know your limits and only drink in moderation. Decide ahead of time how many drinks you'll have—and stick to it. Don't feel pressured to drink.Take it slow. Avoid having more than one alcoholic drink per hour. Stop drinking completely when you've reached your limit (or before then). Frequently Asked Questions (FAQs): How can I get rid of a hangover headache?
