This means that your brain and body are “out of practice” in terms of processing and responding to alcohol. Alcohol tolerance can be explained via several mechanisms—but here are four ways that tolerance may develop and change. Alcohol dependence can have a profound impact on mental health, leading to disorders such as depression and anxiety.

If your body gets used to having three beers at a bonfire in your back yard once a week during the summer, it will start to anticipate that amount of intoxication even before you pop the tab. If someone has two drinks each time they drink, they will never raise their tolerance level, even if they have two drinks every night. It is important to recognize that tolerance is not the same thing as dependence or addiction. Tolerance means you no longer respond to a drug in the same way you did when you first started taking it.

How Long It Takes To Change A Functional Tolerance

Regular tolerance breaks and moderation are better than periods of binging followed by abstinence. For instance, binging on the weekends and avoiding alcohol during the week could prevent tolerance, but binging can come with some other health risks. Many other factors, such as drinking habits, can influence functional tolerance. But it is possible to reverse even a high alcohol tolerance in about a month.

• Your liver handles alcohol, but if you drink too much too quickly, it’ll get overwhelmed.
• With that in mind, like most doctors, Dr. Schwartz would suggest working on cutting out alcohol versus working on getting your body to better tolerate it.
• As your body adapts to alcohol, you need more to feel the same effects.

Functional tolerance

Reports have shown that different individuals have varying degrees of tolerance. The reason is yet uncertain; however, there are several types of tolerance with their own mechanisms. But if they start drinking at their previous levels again, alcohol-related impairments in cognition and behaviour could return – but after having smaller amounts of alcohol. These changes in tolerance reflect the brain’s desensitisation (increased tolerance) and resensitisation (reduced tolerance) to alcohol at the cellular level. No matter what type of tolerance you may have developed, you want to be very thoughtful about how you proceed. Each type of tolerance is likely to lead to an increase in alcohol consumption and amplify your risks for developing dependence, organ damage, problems with completing tasks, and ultimately addiction.

Environment-Dependent Tolerance

Payment of benefits are subject to all terms, conditions, limitations, and exclusions of the member’s contract at time of service. AT’s primary cause is excessive and frequent consumption of alcohol, and tolerance occurs less often with people who only drink occasionally. It’s also important to remember that drinking as much as you used to after a period of drinking less (or not at all) could lead to greater intoxication, blackout and accidents. If you don’t use a period of abstinence wisely, you face risks when you return to drinking. Certain medications and excessive alcohol can work in tandem to suppress or amplify the effects of the other.

Health Implications of Reduced Tolerance

Frequent physical activity may also help thwart the negative effects of alcohol. “As we age, our bodies metabolize alcohol less efficiently and blood alcohol levels remain high in people who are less active and ill-prepared to detoxify its untoward side-effects,” says Dr. Schwartz. But when we drink in a new environment—such as going to the pub for the first time in six months—the compensatory response is not activated, making us more prone to experiencing alcohol’s effects.

Environment-Independent Tolerance

The brain, in response to repeated alcohol exposure, adjusts its neurotransmitter systems. Alcohol primarily affects the GABA and glutamate neurotransmitters, which are responsible for inhibitory and excitatory signals in the brain, respectively. Over time, the brain compensates for alcohol’s depressant effects by increasing glutamate activity and decreasing GABA activity, leading to tolerance. Genetic differences do account for some differences in alcohol tolerance, which in some cases fall along ethnic lines. As described above, most Asians don’t have the alcohol metabolic enzyme alcohol dehydrogenase (ADH), which means they tend to get drunk faster than Americans or Europeans.

Increasing Alcohol Consumption Responsibly

While the causal relationship between frequent and heavy alcohol consumption in older adults and cognitive decline is not certain, research has shown a correlation between the two, especially in men. Jaines M. Andrades, DNP, AGACNP-BC, discusses alcohol, the aging process, the latest research on alcohol as we age, and why hangovers feel worse as we get older. For many adult Americans, a nightcap is a welcome lowering alcohol tolerance ritual at the end of the workday. And, as it turns out, it’s a habit that many continue long past retirement.

Increasing your alcohol tolerance is best done by gradually drinking more servings over time, but there are also things you can do before drinking that will help, too. The most important thing to remember, though, is that you should always drink responsibly, which means pacing yourself and stopping when you or others think you’ve had enough. In fact, people with a family history of alcohol dependence are four times more likely to develop a dependency themselves, Damask said.

Some people have slower variants of these enzymes, which has been linked to tolerance and dependence. Usually, one standard drink is metabolized in one hour, but people who have little or no ADH have no simple way of metabolizing the alcohol. Thus they develop effects and build tolerance faster than people who do have ADH. However, body type, gender, ethnicity, and metabolism are also factors that contribute to the development of tolerance. Men use alcohol a lot more than women do, while women are more likely to get intoxicated faster than men due to body size and their slower metabolism.
