Whether you're wondering how long alcohol stays in your system for personal reasons, workplace testing, or general knowledge, it's a common question with a not-so-simple answer. Alcohol affects everyone differently, and factors like age, weight, metabolism, and drinking habits all play a role. In this article, we’ll break down how alcohol is processed, how long it remains in different parts of your body, and what you need to know about detection times.
How Alcohol Is Processed in the Body
Once consumed, alcohol is absorbed into the bloodstream through the stomach and small intestine. The liver is responsible for breaking down alcohol, but it can only process a limited amount at a time—approximately one standard drink per hour. The rest remains in your bloodstream until your body can metabolise it, which is why blood alcohol concentration (BAC) rises with continued drinking.
How Long Does Alcohol Stay in Different Parts of Your Body?
Here’s a breakdown of how long alcohol can be detected in various systems:
Blood: Up to 12 hours
Breath: 12-24 hours
Urine: 12-48 hours (up to 80 hours for advanced tests)
Saliva: 12-24 hours
Hair: Up to 90 days
Factors That Affect How Long Alcohol Stays in Your System
Not everyone processes alcohol at the same rate. Several factors impact how quickly it leaves your body, including:
Metabolism: Faster metabolism = quicker alcohol breakdown
Age: Older individuals tend to process alcohol more slowly
Weight & Body Composition: More body fat can slow elimination
Hydration Levels: Dehydration can prolong alcohol’s effects
Food Intake: Drinking on an empty stomach leads to faster absorption
Does Anything Speed Up the Process?
A common myth is that drinking coffee, taking cold showers, or exercising can "sober you up" faster. The truth is, only time allows your body to eliminate alcohol. Hydrating and eating nutritious foods may help you feel better, but they won’t reduce your BAC any quicker.
When to Be Concerned About Alcohol Consumption
If you find yourself regularly drinking to excess or struggling to control your intake, it may be a sign of a bigger issue. Long-term alcohol use can lead to dependence, and recognising when alcohol is affecting your health, relationships, or responsibilities is crucial.
