Drinking & You – How does alcohol make you drunk How does alcohol make you drunk? Alcohol is a mood altering substance. It affects the nerves that pass messages around the body by slowing them down, and the more you drink the greater the effect. The reason people often get more lively when they’ve had a drink is that alcohol affects parts of the brain responsible for self-control.
- As you drink, the alcohol passes into your bloodstream.Ethanol is the intoxicating part of alcohol and its molecules are so small that they can actually pass into the gaps between brain cells.
- There it can interfere with the neurotransmitters that enable all the brain’s activities.
- If you drink fast, alcohol will start to flood the brain.
Fortunately, alcohol can give some warning signs as itpenetrates into the brain and central nervous system, so if you spot the signs in yourself or a friend, moderate your or their drinking or stop drinking further amounts. The last thing you would want is to lose control, vomit or end up in hospital.
Severe cases of heavy drinking can result in alcoholic poisoning, coma or death.Your reactions also slow down, and as you drink more, you may become uncoordinated or unsteady on your feet. Your speech may get slurred and you may start seeing double. If you’ve had a lot to drink you may also experience strong emotional responses – for instance you may become aggressive or tearful.
And becauseyour judgement is impaired, you may do things that you might not normally do – from dancing on tables to going home with strangers. They may seem a good idea at the time, but can be extremely dangerous. The classic warning signs of drunkenness
You feel giddy You start to lose the thread of what you’re saying You feel unsteady on your feet You start seeing double.
Tips to avoid feeling sick or passing out
The best advice, of course, is to avoid drinking or to drink within the guidelines to avoid this happening. If someone is planning to drink, they should eat before or while drinking – even a bowl of cereal or a couple of pieces of toast will help. Avoid top ups as it is harder to keep track of what you’re drinking. Pace yourself – having a soft drink between each alcoholic one really helps slow drinking down and gives the body a chance to break down the alcohol consumed.
What are the dangers of drinking to drunkenness? Drinking to drunkenness increases the risk of ending up in the Accident and Emergency Department (about 20% of accidental deaths are alcohol related), getting involved in a fight, not getting home safely, and of being robbed or sexually assaulted.

How does alcohol work in the body?
Brain – Alcohol dulls the parts of your brain that control how your body works. This affects your actions and your ability to make decisions and stay in control. Alcohol influences your mood and can also make you feel down or aggressive. As the concentration of alcohol in your bloodstream increases, your behaviour and body functions change.

There is no immediate way to sober up. It takes time for your body to process alcohol. The morning after a heavy night’s drinking, you are likely to have a high concentration of alcohol in your bloodstream. You may not be sober or safe to drive a vehicle. The legal alcohol limit for driving measures the amount of alcohol in your breath, blood or urine.
How much alcohol does take to get drunk?
Number of Beers To Get You Drunk – The number of beers it takes to get drunk varies depending on factors such as a person’s weight, gender, and tolerance level. Generally speaking, it takes about 3-4 beers for the average person to feel tipsy, and around 5-6 beers to become legally intoxicated.
Why do I drink to get drunk?
A lcohol is a very simple molecule with incredibly complex effects. Although I already knew a bit about the neurobiology of alcohol, I just spent an afternoon reading a dense journal article that described roughly 50 different neural mechanisms it affects.
After which I felt like I needed a drink. It’s widely known that alcohol reduces stress temporarily, and many people use it for just that purpose. It reduces stress by increasing the uptake of a neurotransmitter called GABA, the brain’s primary inhibitory molecule. (And by “inhibitory” I don’t mean that it makes you feel inhibited.
Quite the opposite, of course.) By sending more GABA to your brain cells, alcohol works much like common tranquillising drugs such as Valium and Xanax. That’s why you start to stumble and slur if you drink too much. But alcohol acts on many other neurotransmitters too.
I’ll mention three important ones and show how they contribute to the joys of inebriation. While alcohol increases GABA, it reduces the uptake of glutamate, the brain’s premier excitatory molecule, Less excitation and more inhibition? That sounds like simple summation, but GABA and glutamate have different effects on different brain regions, and that’s where things get complicated.
In the prefrontal cortex, the part of the brain you use for thinking and planning, the net effect is inhibition. That’s why your judgment is flawed, your decision-making is set to “whatever” and your ability to see things from any perspective other than your own approaches nil.
The remarkable side effect of this general dimming is that your thoughts seem amazingly clear – which is nice – while in reality they are just amazingly limited. Meanwhile, GABA is also busy turning off the brakes on a system that releases dopamine, the molecule that takes centre stage in all varieties of addiction.
What’s that again? Well, when you take off the brakes, the car starts to move. So what you get is a stream of dopamine coursing into the striatum (or reward system), the brain part that generates desire, anticipation and (once you’ve finally brought the glass to your lips) pleasure.
- So far, you’ve got physical relaxation, which diminishes stress, reduced judgment, allowing you to talk and behave however you want, and stimulation of the brain’s reward system, which makes you feel like something nice is about to happen.
- But the fourth neurotransmitter tops the bill: opioids.
- Sometimes called endorphins or internal opiates, they get released by alcohol too.
Everyone knows that opiates feel good, but did you know that you can get your opiates legally by downing a stiff drink? The American martini – which consists of three ounces of gin and little else – feels particularly nice for a very simple reason. The faster the alcohol goes in, the more internal opiates get released. Aaaaaahhhh! A dry martini, with its three ounces of gin. Photograph: Alamy Given all the things that make up an alcohol high, it shouldn’t be surprising that inebriation feels different to different people, feels different from the first to the last drink, and definitely feels different once it becomes hard to stop.
- People who carry around a lot of stress drink to relax.
- People who spend a lot of energy controlling their impulses drink in order to let themselves go.
- The first drink of the night excites you, the last drink of the night sedates, and that isn’t nearly as much fun.
- College kids indulge in binge-drinking because they’re still bright-eyed novices when it comes to taking chemicals that alter their mood – the more the merrier.
Twenty years later, they may drink to feel less, not more, because life has become oppressive, and anxieties seem ready to spring from every train of thought. But once people become addicted to alcohol, as many do, the fun of the high is eclipsed by two opposing fears.
- The fear of going without, versus the fear of being unable to stop.
- That clash of concerns comes from several sources.
- First there are the unpleasant bodily effects that plague big drinkers when they stop for a few hours or, worse, a few days.
- Add to that the emotional emptiness, depression, and increased stress responsiveness that overcome the drinker’s mood at the same time.
Taken together, these effects make up what George F Koob calls the dark side of addiction, But I think the real bogeyman, the unbeatable Catch-22 when it comes to alcohol and other drugs, is the realisation that the thing you rely on to relax is the very thing that stresses you out the most.
- It’s hard to find a way out of the recurrent cycle of anxiety and temporary relief, over and over, and that’s the epitome of a losing battle.
- People like to get drunk because alcohol smacks your brain around in a number of ways that feel pleasant, or at least different, or at the very least better than going without.
And that’s really how all mood-altering drugs work. Which is generally OK, because recreational drug use, including drinking, doesn’t lead to addiction for most people, But for those who get caught, the fun soon disappears. When the fun stops. Photograph: Alamy Drugs, including alcohol, fashion neural habits: get it, take it, lose it, then get it again. And those habits narrow the brain’s focus to a very singular goal, at the expense of everything else. The striatum – the brain’s reward system – is responsible, not just for pleasure, but more seriously, for feelings of desire.
- And desire isn’t fun, unless you’re just about to get whatever it is you want.
- Then, the more you get it, the more your striatum gets tuned by that surge of dopamine, modifying its synaptic wiring a little bit at a time until other goals just don’t count for much.
- But alcohol has one advantage over drugs like heroin and cocaine.
It’s legal, and socially sanctioned. In fact drinking has become deeply enmeshed with themes of social engagement, joyful celebrations and all the rest of it. Drinking doesn’t make you a bad person – in fact it seems to put you in good company and thereby make you a good person – if you can resist its addictive lure.
How long do you stay drunk?
How long does it take alcohol to get out of your system? – Alcohol reaches its peak blood levels 60 to 90 minutes after you start drinking. The body then starts to metabolize it. The half-life of alcohol is four to five hours. This means that’s how long it takes for your system to eliminate half of it.
How will I act when I’m drunk?
3. Excitement – At this stage, a man might have consumed 3 to 5 drinks, and a woman 2 to 4 drinks, in an hour:
You might become emotionally unstable and get easily excited or saddened.You might lose your coordination and have trouble making judgment calls and remembering things.You might have blurry vision and lose your balance.You may also feel tired or drowsy.
At this stage, you are “drunk.” BAC: 0.09–0.25 percent
What is the mechanism of action of alcohol?
Alcohol intoxication results in CNS depression by enhancing the effect of GABA, an inhibitory neurotransmitter, on its receptors. It also inhibits the actions of ‘glutamate’ on the NMDA receptors, resulting in an incautious and dull state of mind.
How does alcohol work as a depressant?
How does alcohol affect the brain and central nervous system – Alcohol is known as a psychotropic depressant because it slows down your central nervous system. When you drink alcohol, a complex process occurs in your brain that inhibits neurons by impacting their ability to transmit impulses.
At the same time, alcohol also increases the production of neurotransmitters that make you feel good. As a review, your body’s nervous system plays an important role in communication between the brain and the rest of the body to control every day functions such as seeing, talking, walking and breathing.
The nervous system is made up of the central nervous system and the peripheral nervous system. The central nervous system contains neurons in the brain and spinal cord, while the peripheral nervous system contains neurons in the head and body. The job of the peripheral nervous system is to carry messages from the brain to other parts of the body.
- Neurons use both electrical and chemical signals to communicate information – chemical signals are needed because electrical signals alone can’t transfer from one neuron to another.
- The chemical signals, known as neurotransmitters, help bind neuron receptors.
- Neurotransmitters help carry these messages to neurons.
As alcohol enters the body, it binds to certain neurotransmitters that are responsible for inhibiting communication and causes them to slow down, resulting in decreased brain activity. This lag in processing slows down your alertness, balance, movement and ability to think.
