Negative effects of alcohol tolerance

You can drink enough alcohol for a period of time to develop tolerance to some of its effects. If you drink it for long enough, you may find that drinking the same amount of wine you usually drink will not produce the same effect.

In other words, if you have developed alcohol tolerance, you must drink more and more alcohol in order to experience the same effects that you experienced when drinking less alcohol.

You may think that the absence of alcohol to interfere with your behavior and the ability to function as in the past is a positive phenomenon, but the development of tolerance to alcohol may actually herald outstanding issues.

Tolerance to the effects of alcohol can affect drinking behavior and consequences in many ways.

There are many ways to develop alcohol tolerance:

Functional tolerance

Functional tolerance refers to the adaptation of the brain function of drinkers to compensate for the damage caused by alcohol to their behavior and body functions.

Do you know someone who can drink a lot without any obvious signs of drunkenness? That’s because that person has developed a functional tolerance to alcohol.

When someone has drunk enough alcohol and they should show some signs of behavioral disorder and they do not, their tolerance to alcohol allows them to drink more alcohol.

Functional tolerances can lead to dependencies

The problem is that higher consumption levels can lead to the body’s dependence on alcohol and alcohol-related organ damage.

However, studies have found that functional tolerance can develop at the same rate for all the effects of alcohol. For example, someone may quickly develop a functional tolerance for mental functions (such as solving puzzles), but not for tasks that require hand-eye coordination (such as driving a vehicle).

Different types of functional tolerances

Sometimes, drinkers will quickly become tolerant to the unpleasant effects of poisoning, such as nausea or dizziness, but not to the pleasant effects. This can lead to an increase in alcohol consumption.

There are different types of functional tolerance to alcohol, which are produced by different factors and influences.

Acute tolerance

When a drinker develops tolerance to the effects of alcohol during a drink, it is called acute tolerance. Drinkers may seem more intoxicated early in the drinking phase than they are towards the end.

However, acute tolerance usually develops into a “feel” of poisoning, but not all the effects of alcohol. Therefore, the person may be prompted to drink more water, which will impair the body functions that are not acutely tolerated.

Environment-related tolerances

Studies have found that if drinking in a series of drinking processes always occurs in the same environment or accompanied by the same prompts, alcohol tolerance can be accelerated.

Studies have found that when drinkers have been drinking in the same room, their heart rate increase is smaller than when drinking in a new environment.

Clues related to drinking

Another study found that “social drinkers” who accept eye-hand coordination tasks perform better if they drink in a bar-like environment rather than an office environment.

The researchers concluded that the subjects were more tolerant of alcohol in a bar environment because it contained cues related to drinking. This is called environmental tolerance.

Learn to be tolerant

Practicing tasks under the influence of alcohol can also accelerate alcohol tolerance. Even if the subjects only rehearsed the task psychologically after drinking, they would develop the same tolerance as those who actually performed the task while drinking.

This is called behavior enhancement tolerance or learning tolerance.

Rewards affect tolerance

The expectation of rewards can also accelerate the tolerance of learning. One study found that subjects who knew they would successfully complete tasks and earn money when they were affected developed tolerance faster than they did not expect rewards.

How does this apply to real life?

Driving the same route home repeatedly while in a drunk state may cause the driver to become tolerant of the task and reduce the damage caused by alcohol. However, the tolerance of this particular task cannot be transferred to the new task.

For example, if the driver encounters an unexpected situation, a detour, or a change in driving conditions, he may lose any previously acquired tolerance to alcohol impairing his driving skills.

Environment-independent tolerance

Functional tolerance to alcohol can develop independently of the environmental effects of exposure to large amounts of alcohol. Researchers found that after using a lot of alcohol, experimental animals developed tolerance in an environment different from alcohol.

This is called tolerance independent of the environment.

Metabolic tolerance

Metabolic tolerance occurs when a certain set of liver enzymes are activated after long-term drinking for a period of time, leading to faster elimination of alcohol from the body.

This activation of liver enzymes increases the degradation of alcohol and reduces the time that alcohol is active in the system, thereby reducing the time of poisoning.

Metabolic tolerance can lead to liver damage

However, when long-term drinking activates these enzymes, it can cause health problems for long-term drinkers, because it also affects the metabolism of other drugs and drugs, and may have harmful effects, including liver damage.

Studies have also found that metabolic tolerance can also cause certain drugs to be ineffective for chronic drinkers or even abstainers.

Tolerance and tendency to alcoholism

Research shows that certain aspects of alcohol tolerance are inherited. Several studies comparing sons of alcoholic fathers with sons of non-alcoholic fathers have found that differences in tolerance may affect drinking behavior.

Some studies have found that sons of alcoholic fathers are less affected by alcohol than sons of non-alcoholic fathers.

Other studies have found that the sons of alcoholic fathers show strong tolerance to alcohol-experiencing the pleasurable effects of alcohol in the early stages of drinking, but not experiencing the damaging effects of alcohol in the later stages of drinking.

The genetic predisposition to alcohol tolerance may lead to increased alcohol consumption and risk of alcoholism in the sons of alcoholic fathers.

Does tolerance indicate the risk of alcohol use disorder?

The rapid development of tolerance to the effects of alcohol may be a clue that alcoholics, whether they are the sons of alcoholics or not, are at risk for alcohol-related problems.

If someone you know is said to be able to “maintain alcohol well” or drink a lot of alcohol without showing signs of poisoning, that person may suffer from medical complications and drinking disorders due to drinking.
