Alcohol is a common part of social life in Australia, but understanding how to manage your Blood Alcohol Concentration (BAC) is essential for safety and legal compliance. If you’re wondering how to reduce alcohol in your blood, it’s important to know what works-and what doesn’t. This blog breaks down effective ways to lower your BAC and explains the science behind alcohol metabolism.
What Is BAC and Why Does It Matter?
BAC is the percentage of alcohol in your bloodstream. In Australia, the legal driving limit is 0.05%, meaning if your BAC is 0.05 or higher, you are legally impaired to drive. High BAC levels affect your coordination, judgment, and reaction times, increasing the risk of accidents.
The Only Reliable Way: Time
The most important fact to understand is that the only proven method to reduce BAC is to allow time for your body to metabolise the alcohol. On average, your liver processes alcohol at a rate of about 0.015% BAC per hour. This means if your BAC is 0.10%, it could take roughly 6 to 7 hours to return to zero.
No shortcuts like coffee, cold showers, or exercise speed up this process. These might make you feel more alert but do not lower the alcohol in your blood.
Tips to Prevent Your BAC from Rising Too High
While you can’t quickly reduce alcohol already in your bloodstream, you can slow its absorption and avoid spikes in BAC:
- Eat before and while drinking: Food slows alcohol absorption, helping keep BAC levels lower.
- Pace your drinking: Limit yourself to about one standard drink per hour to give your body time to metabolise alcohol.
- Alternate with water or non-alcoholic drinks: This helps keep you hydrated and slows down drinking.
- Choose lower-alcohol beverages: Opting for drinks with less alcohol content reduces total intake.
What About Natural Remedies and Supplements?
Some studies have explored herbal formulas and natural compounds that might help reduce BAC more quickly. For example, a study on a natural compound formula called RM88 showed promising results in lowering peak BAC levels in moderate drinkers. However, these findings are preliminary, and such supplements are not widely available or endorsed as reliable methods for BAC reduction.
Common Myths Debunked
- Coffee or caffeine: May make you feel awake but does not lower BAC.
- Cold showers: Can refresh you but don’t affect alcohol metabolism.
- Vomiting: Removes alcohol from your stomach but does not reduce BAC once alcohol is absorbed into your bloodstream.
- Exercise: Burns calories but has minimal effect on how quickly alcohol leaves your system.
What to Do If You Need to Drive
If you’ve been drinking, the safest and smartest choice is to avoid driving altogether. Use alternative transport like taxis, rideshares, or public transport. Remember, even if you feel sober, your BAC might still be above the legal limit.
In Australia, the only effective way to reduce alcohol in your blood is to wait for your body to metabolise it naturally over time. While you can take steps to slow alcohol absorption and avoid rapid BAC increases, no quick fixes exist to instantly lower your BAC. Planning ahead and drinking responsibly is the best way to stay safe and within the law.
