According to the Cleveland Clinic, hangovers are extremely common among people who overdrink. One study found that nearly 75% of people who consumed excessive alcohol reported hangover symptoms the following day. The same research suggested that about 25% to 30% of drinkers may not experience hangovers at all.How Much Alcohol Does It Take To Get A Hangover?Drinking more than one alcoholic beverage per hour can lead to a hangover. Your body generally needs about an hour to break down and process a single drink. As explained by the Cleveland Clinic, one drink is roughly equal to:One 12-ounce can of regular or light beer (5% alcohol).Half a pint, or about 8 to 9 ounces, of malt liquor or many craft beers (7% alcohol).One 5-ounce glass of table wine (12% alcohol).One shot, or 1.5 ounces, of liquor (40% alcohol).How To Cure Hangover Headache At Home?Many products and home remedies claim they can cure a hangover, but most are not supported by science, and some may even do harm. For instance, having more alcohol the next morning does not fix a hangover. It simply adds more toxins to your system.Instead, consider these self-care measures for hangover relief:Eat simple foods with complex carbohydrates, such as toast or crackers. These can help raise low blood sugar levels and ease nausea.Drink plenty of fluids. Water, electrolyte drinks like Gatorade® or Pedialyte®, broth, and other non-alcoholic beverages can help counter dehydration. A good sign you are rehydrated is when your urine becomes clear.Get adequate sleep to help your body recover from fatigue.Use antacids to calm stomach discomfort.Consider aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen to relieve aches and pains. NSAIDs are generally the most effective medications for hangover-related pain, but they should be used cautiously because they can irritate your stomach. Avoid acetaminophen (Tylenol), as combining it with alcohol can damage your liver.Give it time. Hangover symptoms usually improve within eight to 24 hours. During this period, your body works to eliminate alcohol toxins, restore hydration, repair tissues, and return normal body functions to baseline.
