3. Eating and drinking – Eating before, during, and after drinking can help slow the absorption of alcohol into the bloodstream. Drinking plenty of water can also assist with dehydration and flushing toxins from the body.

Factors that impact BAC – Number of standard drinks and rate of consumption
BAC will rise relative to the number of drinks consumed and how quickly they are consumed.
Body size and composition
Body size determines the amount of space that alcohol has to diffuse throughout the body. In general, a person with a larger build who drinks the same as a person with a smaller build will have a lower BAC due to the amount of space alcohol has to distribute through. Alcohol diffuses more into muscle than fat because muscle tissue has a large amount of blood that flows through it. This means that an individual’s muscle to body fat ratio will impact their BAC, as it correlates to the amount of blood available for alcohol to enter. For example, someone with a higher percentage of body fat will experience a more rapid increase in BAC, as alcohol will become more concentrated in the blood of their muscle tissue.
Testosterone and estrogen levels
People with higher levels of testosterone generally have more muscle mass and less body fat than people with higher levels of estrogen. Muscle contains more blood than body fat. The larger volume of blood in those with greater muscle mass allows alcohol to dilute more through the bloodstream and BAC to remain lower. People with higher levels of testosterone are composed of approximately 55-65% water, whereas people with higher levels of estrogen are composed of about 45-55% water. Alcohol becomes more diluted in bodies with greater volumes of water, resulting in lower BAC levels for people with higher levels of testosterone as compared to those with higher levels of estrogen. Individuals with higher levels of testosterone have higher levels of alcohol dehydrogenase, an enzyme that helps break down alcohol. This means that individuals with higher levels of testosterone can more efficiently break down alcohol as compared to individuals with higher levels of estrogen, who have more alcohol enter their bloodstream, resulting in higher BAC levels. Research has found that due to changes in hormone levels, individuals who have periods experience slower alcohol metabolism and higher levels of intoxication in the week leading up to their period. Oral contraceptives and other medications with estrogen also slow the rate at which individuals process alcohol.
Additional drugs or medications
Other drugs and medications, even those prescribed to you, can have adverse effects and unpredictable interactions with alcohol. It is important to ask your doctor if any medications you might be taking have harmful effects when taken with alcohol.
Amount of food consumed
Food present in the stomach causes the alcohol to move down into the small intestine slower than it would on an empty stomach. While it’s a common myth that food absorbs alcohol like a sponge, it actually causes a “traffic jam” in the body, making the processing of alcohol take longer. This reduces the risk of a rapidly rising BAC level.
Emotional state, mood and level of fatigue
Alcohol has a more pronounced effect on those who may be fatigued or under stress. Since alcohol is a depressant, someone who is depressed may experience heightened signs of depression upon drinking.
Menstrual cycle
Research has found that due to changes in hormone levels, individuals who have periods experience slower alcohol metabolism and higher levels of intoxication in the week leading up to their period.
Type of beverage or mixer
Fruit juices slow down the processing of alcohol because the sugar requires digestion, resulting in a slower rise in BAC. On the other hand, carbonated mixers or drinks can cause BAC to rise more rapidly because the carbonation speeds up absorption.
It is important to note that common strategies used to “sober up,” such as taking a cold shower, sleeping, drinking water and consuming caffeine, do not work to lower BAC. The only thing that can help alcohol leave your bloodstream is time.
How long does it take for blood alcohol level to go down?
How Long Can a Breathalyzer Test Detect Alcohol On Your Breath ? – So then, how long after drinking can you use an Ignition Interlock ? It’s important to understand that you cannot “beat” a breathalyzer. Breathalyzers are highly accurate and reliable given regular maintenance and calibration, both of which are required if you use a car breathalyzer.
Really, the question of how long a breathalyzer can detect alcohol comes down to how you metabolize alcohol. Once alcohol enters your body and bloodstream, it can only exit through two means. About 10 percent leaves through your urine, breath, and sweat. The other 90 percent is metabolized naturally in the body.
The rate of metabolism can differ based on a wide range of factors, but experts generally agree that it takes one hour to break down 0.015 of blood alcohol concentration, meaning that for every hour that you are not drinking, your BAC will go down by 0.015.
- One standard drink (which is considered any drink containing 14 grams of alcohol) will increase your BAC by a maximum of 0.02, based on your body size, gender, and other factors.
- Within about an hour, your blood alcohol concentration would be at almost zero.
- The problem usually comes when you drink at a faster rate or otherwise drink several alcoholic drinks at once (like taking several shots).
Your liver cannot process alcohol that quickly, causing it to accumulate in your blood and leading to a higher BAC. For the average person, it only takes about three or four drinks in one hour to reach a BAC of 0.08. Given the general rule, if your blood alcohol content is at the limit of 0.08, it would go down to 0.065 after one hour.
It would take roughly five hours and twenty minutes for your body to completely metabolize the alcohol and eliminate it from the body. That’s also why it can be dangerous to drink too late into the night. If you have a high enough BAC, you may still actually be drunk when you wake up, which can still be a real problem if you have to drive to work.
Those who have been binge drinking can have alcohol in their systems for over 10 hours. Breathalyzers can detect alcohol within 15 minutes of your first drink and can continue for as long as the alcohol is in your system. Coffee, cold showers, and “sleeping it off” will not sober you up.
What lowers a person’s blood alcohol level?
Blood Alcohol Content (BAC) Calculator – Blood Alcohol Content, or BAC, refers to the percentage of alcohol in a person’s bloodstream, and can be measured within 30-70 minutes after drinking. Contrary to popular belief, nothing can lower BAC except time; coffee, cold showers, and chugging glasses of water will not help you sober up any faster.
Does food lower blood alcohol level?
Eating food, either before or while drinking, essentially slows absorption rates. Slower rates mean that less alcohol enters a person’s bloodstream (when compared to a drinker that does not eat). This reduction of alcohol in the blood translates into reduced levels of blood alcohol concentration.
How much does BAC go down after 3 hours?
How Fast Does Your BAC Drop After Drinking? You think that you waited long enough after drinking to be safe to drive. You eat some food and drink a cup of coffee. You feel all right. Then, as you drive through Las Vegas, a police officer pulls you over.
You’re not quite sure what you did to warrant the stop, but you do pull over and talk to the officer. They ask you to do some field sobriety tests and then take a breath test. Still thinking you waited long enough that you won’t fail, you take the test. And you do fail. You get arrested. It’s not at all how you wanted your night to go.
What happened? BAC rates The problem is likely that you did not wait long enough after all. People often misjudge just how intoxicated they are and how the alcohol can impair their driving and judgment. What you need to know is that the rate that your Blood Alcohol Concentration (BAC) drops is about,
- This is true for almost everyone, regardless of their weight, height, age or any other factor.
- If you drink, that’s how fast your body can metabolize the alcohol and get it out of your system.
- So, how long did you really wait? An hour? Two? Depending on where your BAC started, it may not have fallen as far as you think.
For example, imagine that you started right at the legal limit of 0.08 percent. In the first hour after you put your drink down, your BAC would only fall to 0.065 percent. Another hour after that, you would hit 0.05 percent. In three hours, you’d reach 0.035 percent, and then you’d get to 0.02 percent after the fourth hour.
- Alcohol would remain in your system even after five hours, though just at 0.005 percent.
- It would take roughly five hours and 20 minutes for you to completely metabolize all of the alcohol you consumed and get back down to 0.00 percent.
- And that is just if you start at 0.08, which is right at the legal limit.
If you were at 0.10 when you stopped drinking and you waited for an hour, you would still be at 0.085 percent when you got in the car. Remember, the way you feel can be deceptive. It depends on your alcohol tolerance and how often you drink. Your defense options If you do get arrested for a DUI when you thought you did everything possible to stay safe, you could still face some serious ramifications.
How much does your BAC go down in 2 hours?
How Fast Can You Sober Up? – Alcohol leaves the body at an average rate of 0.015 g/100mL/hour, which is the same as reducing your BAC level by 0.015 per hour. For men, this is usually a rate of about one standard drink per hour. However, there are other factors that affect intoxication level (gender, some medications, illness) that will cause BAC to rise more quickly, and fall more slowly.
Does throwing up lower your blood alcohol level?
Myth: Throw up to sober up – Throwing up won’t reduce your blood alcohol level. Alcohol is absorbed into your bloodstream very quickly, so it won’t make much difference unless you vomit immediately after taking a sip. However, drinking too much can make you nauseous, and throwing up often helps relieve nausea. Even so, trying to make yourself throw up is not a good idea.
How do you help someone who drank too much?
Helping your friend – Acting quickly when you think your friend has had too much to drink can help avoid more serious consequences. Remember, when someone has had too much to drink, their judgement might be impaired, so don’t get angry with your friend.
Get them a glass of water or a soft drink, or even order them some food. This will stop them drinking and give their bodies time to process the alcohol. In the future, agree a drinks limit with your friends and make sure you have some soft drinks or water. For example, for each alcoholic drink you have, you could have one or more glasses of water before and afterwards.
Also, make sure you both eat a meal before you have anything to drink. You could consider setting a budget for the night or only taking limited cash with you.
