Here’s what we do know about alcohol’s effects on the body and how it may bring on a hangover. The occasional hangover is probably nothing to worry about. However, frequent hangovers could be a sign of alcohol abuse and warrant talking to your doctor. Alcohol abuse is a pattern of drinking too much alcohol too often. Alternating alcoholic drinks with non-alcoholic ones can also help you space out your consumption of alcohol and drink in moderation.

Each person’s tolerance level is different, so “moderation” likely varies somewhat from person to person. Tolerance is based on genetics, body type, sex, and other factors. This involves the body regulating itself as the alcohol leaves the bloodstream. However, the progression and severity of symptoms over time can vary from one person to the next. For some people, as little as one drink can trigger a hangover. The darker the alcohol, the more congeners there are.
