What is Blood Alcohol Concentration?
Blood Alcohol Concentration (BAC) is a measure of the amount of alcohol in drinks such as wine and beer. Also known as ethanol concentration, this metric measures the amount of alcohol in the blood after consuming alcoholic beverages. BAC is calculated as the number of milliliters of pure ethanol in 100 milliliters of solution at a temperature of 20 degrees Celsius.
Measuring BAC is crucial for ensuring road safety and personal health. To calculate BAC, several factors must be considered, including gender, weight, alcohol ratio, and the volume of alcohol consumed. Typically, the ideal time to measure BAC is 30 to 70 minutes after consumption, as this is when the alcohol has been absorbed and distributed throughout the body.
According to Article 8, Clause 8 of the 2008 Road Traffic Law, operating a vehicle while having a BAC above the legal limit is prohibited.

Blood Alcohol Concentration measures the amount of alcohol in drinks such as wine and beer.
Measures to Reduce Blood Alcohol Concentration
Lemon Salt Water
Lemon salt water is a popular hangover remedy. The acid and vitamin C in lemons help boost metabolism and break down alcohol while also rehydrating and replenishing electrolytes, making you feel more alert.
Drink Plenty of Water
Consuming ample water speeds up metabolism and eliminates alcohol through urine. It also compensates for the water loss that occurs after drinking alcohol.
Sugarcane and Kumquat Juice
Sugarcane juice, rich in fructose, effectively breaks down alcohol. Adding kumquat, similar to lemon, helps temporarily reduce alcohol concentration in the breath.
Hot Chocolate
A cup of hot chocolate can temporarily reduce alcohol concentration in the breath due to its distinct flavor. It also promotes relaxation, as phenylethylamine in chocolate stimulates the body to produce dopamine and serotonin.
Ginger Tea
Ginger improves blood circulation and aids in alcohol elimination. Fresh ginger or packaged ginger tea can be used. Ginger tea also alleviates nausea associated with drunkenness.
Green Tea
Green tea not only freshens your breath but also enhances the liver’s ability to detoxify due to its tannin and antioxidant content. However, avoid drinking green tea on an empty stomach or when feeling nauseous.
Mint Leaves
Chewing fresh mint leaves can help reduce the alcohol odor in your breath. After thoroughly chewing the mint leaves, you may drink water if needed.
Note
The above measures only temporarily mask the alcohol odor and do not eliminate alcohol from the breath or body. As alcohol in the breath originates from the lungs, it is impossible to deceive a breathalyzer. The best way to ensure safety after drinking is to refrain from driving and instead opt for a taxi or have a designated driver.
To mitigate the effects of alcohol, drink in moderation, eat before drinking, pace yourself, and choose beverages with lower alcohol content. Enhancing liver function is also effective, which can be achieved through a scientific approach to diet, lifestyle, and the use of liver health supplements.
