What are the best scientifically proven hangover cures?
There is no scientific evidence to support any specific food or drink as a hangover cure. However, there are some lifestyle changes that may help prevent or reduce headaches and nausea associated with hangovers:

1. Eat a healthy breakfast before going out. Eating protein-rich foods such as eggs, chicken, or fish can help keep your blood sugar stable and lessen the severity of hangovers. Also, caffeine, alcohol, and nicotine can disrupt your sleep, so make sure you get plenty of rest the night before drinking.
2. Choose low-alcohol drinks. Drinking only beer or wine may cause more severe hangovers compared to mixing other types of alcohols like whiskey or vodka into your drink. Generally, darker liquors have higher amounts of congeners ( impurities) that contribute to hangovers.
3. Stay hydrated by consuming lots of water throughout the day. When you're dehydrated, your body produces more cortisol, which worsens hangover symptoms. Also, avoid sugary mixed drinks, as they contain high levels of calories but little actual juice.
4. Get enough sleep. Alcohol interferes with sleep, so it's important to try to catch up on your zzzs the next morning. If necessary, take an over-the-counter sleep aid such as valerian root to help relax you and fall asleep.
5. Exercise regularly. Regular physical activity helps improve mood, regulate stress hormones, and counteract the negative effects of alcohol consumption on the liver. Just be careful not to exercise too close to bedtime, as this can interfere with sleep.
6. Don't consume large amounts of spicy or acidic foods before going out. These type of foods can irritate the stomach and increase the production of acids in the gut, causing worse hangover symptoms.
7. Reduce or eliminate your use of drugs or excessive alcohol. Abusing drugs or drinking heavily increases your risk for dehydration, poor judgment, and serious health problems down the road. By reducing or eliminating these habits, you'll greatly decrease the likelihood of experiencing a hangover.
