Hangovers are virtually unavoidable for the drinking public. But despite how common they are, scientists don’t fully understand how to cure or prevent hangovers, or even what causes them. In the absence of evidence, people have come up with plenty of their own rituals, from pre-bedtime routines (chugging water) to strict rules about when to drink which type of alcohol (beer before wine).
