How does drinking affect your mood and anxiety?
Perhaps a glass of wine takes the edge off a hard day, yet the next morning you feel jittery, low or oddly on edge. Or perhaps you drink to get through social events and have started to wonder whether alcohol is easing your anxiety or quietly feeding it.
These are common questions. Alcohol has real, measurable effects on the brain systems that regulate mood, stress and sleep, and alcohol and mental health are closely linked. The relationship often runs in both directions: low mood and anxiety can lead to drinking, and drinking can make low mood and anxiety worse.
This article explains how that happens, what the evidence does and does not show, and which signs are worth discussing with a doctor. It will not tell you how much is safe for you to drink, diagnose a drinking problem or replace advice from a clinician who knows your health history.

Why a drink feels calming at first, and why the effect reverses
Alcohol is a central nervous system depressant. In the short term it boosts the activity of GABA, the brain’s main calming chemical messenger, and dampens glutamate, which normally keeps the brain alert.
The result is the familiar early effect: muscles loosen, worries feel further away and social inhibitions drop. Alcohol also prompts a release of dopamine in reward pathways, which adds a sense of pleasure and makes the experience feel worth repeating.
That relief is real, but it is temporary. The World Health Organization describes alcohol as a psychoactive substance that contributes to a wide range of health conditions, including mental and behavioural disorders.
The brain constantly works to keep itself in balance. When alcohol pushes it towards sedation, it pushes back by turning down calming signals and turning up excitatory ones.
Once the alcohol has been processed, that counter-adjustment is left with nothing to offset it. For a while the nervous system can run slightly “hot”, which may show up as restlessness, a racing heart, irritability or a vague sense of dread the next day.
Many people call this “hangxiety”. Research on it as a distinct experience is still limited and it seems to vary a lot between individuals, but the underlying rebound mechanism is well described. Dehydration, poor sleep and regret about things said or done while drinking can all add to the feeling.
With regular heavy drinking, the brain’s adjustments become more lasting. That is one reason people who drink heavily over time can feel more anxious between drinks, and why stopping suddenly can trigger withdrawal symptoms such as marked anxiety, shaking and sweating.
Alcohol and low mood: which comes first?
People living with depression are more likely than average to drink heavily, and people who drink heavily are more likely to experience depression. When a substance use problem and a mental health condition occur together, clinicians call it a dual diagnosis, and co-occurring conditions are common enough that many services now screen for both.
The direction can go either way. Some people start drinking more to manage sadness, emptiness or stress, while for others heavy drinking comes first and depressive symptoms follow.
Alcohol can contribute to low mood in several ways. It disrupts sleep, affects brain chemistry involved in mood, can strain relationships and work, and often leaves people feeling guilty or ashamed, which feeds the cycle.
The DSM-5-TR recognises that depressive symptoms can sometimes be caused by a substance, including alcohol. In practice, clinicians often look at whether symptoms persist after a period without drinking, which helps them decide what kind of treatment is likely to help.
If you have noticed persistent low mood, our guide to depression symptoms beyond sadness describes signs worth raising with a doctor, whether or not alcohol is involved.
How drinking can keep anxiety going
Anxiety conditions and alcohol problems also frequently occur together. One common pattern is drinking to manage social anxiety: having a drink before a party, a date or a work event so that it feels bearable.
Cognitive behavioural models of anxiety explain why this can backfire. When alcohol is used as a “safety behaviour”, the person never gets the chance to learn that they could have coped without it, so the fear stays intact and the next event feels just as daunting.
Over time, alcohol can become linked in the mind with relief itself. Repeatedly using a substance to escape a feeling can change how the brain’s reward and stress systems respond, and the American Psychiatric Association describes substance use disorders as involving changes in brain function that can affect thinking and behaviour.
Something similar can happen after frightening or traumatic experiences. Alcohol may briefly blunt distressing memories or help with sleep, but it can also interfere with the natural processing that helps people recover, and it is linked with worse outcomes when used this way.
If you often feel anxious without an obvious trigger, it may help to read about why anxiety can appear for no clear reason, and to consider honestly whether drinking patterns are part of the picture.
The sleep connection
Sleep is one of the main routes through which alcohol affects mood. Alcohol can make it easier to fall asleep, which is why some people rely on a nightcap, but alcohol tends to disrupt sleep later in the night.
As the body processes alcohol, sleep becomes lighter and more broken, with more awakenings in the second half of the night. Alcohol also suppresses REM sleep, the stage associated with dreaming and emotional processing, during the early part of the night.
Poor sleep, in turn, makes people more emotionally reactive, less able to handle stress and more prone to low mood. So even when alcohol seems to help with sleep, the quality of rest is often worse, and the following day can feel harder.
This can become its own loop. A tired, anxious day makes a drink in the evening more tempting, which then leads to another unsettled night.
If sleep has become a struggle, our article on evidence-based steps to sleep better covers approaches such as cognitive behavioural therapy for insomnia, which clinical guidelines recommend as a first-line treatment for long-term sleep problems.
Signs drinking may be affecting your mental health
Before looking at warning signs, it helps to see the gap between how alcohol often feels in the moment and what tends to happen with frequent or heavy use. Effects vary between people, so this is a general picture rather than a prediction.
| Area | In the moment | Later, or with regular heavy use |
|---|---|---|
| Anxiety | Feeling calmer and less self-conscious | Rebound anxiety, restlessness, worry between drinks |
| Mood | A lift in mood, a sense of pleasure | Lower mood, guilt, irritability, higher risk of depressive symptoms |
| Sleep | Falling asleep faster | Broken sleep, early waking, less restful nights |
| Coping | Problems feel more distant | Problems remain, with fewer chances to build other coping skills |
| Judgement | Fewer inhibitions | More impulsive decisions, conflict and regret |
There is no single line that separates “fine” from “a problem”. The National Institute on Alcohol Abuse and Alcoholism describes alcohol use disorder as a medical condition marked by an impaired ability to stop or control drinking despite negative consequences, ranging from mild to severe.
The following are signs worth discussing with a clinician. They are not a diagnosis, and having one or two does not mean you have a disorder.
- Drinking mainly to cope with anxiety, stress, loneliness or low mood.
- Feeling more anxious, low or irritable on the days after drinking.
- Finding it hard to cut back when you want to, or drinking more than you planned.
- Needing more alcohol to get the same effect.
- Feeling shaky, sweaty, restless or unable to sleep when you go without.
- Drinking getting in the way of work, relationships or things you used to enjoy.
- Friends or family expressing concern, or hiding how much you drink.
Some people are more vulnerable than others. A family history of alcohol problems, starting to drink at a young age, past trauma and an existing mental health condition are all recognised risk factors.
If several of these signs feel familiar, you are far from alone. NIAAA’s alcohol facts and statistics show that alcohol use disorder affects millions of adults in the United States, and that only a small proportion receive treatment in any given year.
Changing your relationship with alcohol safely
If you decide to drink less or stop, a few principles can make the process safer and more likely to last. Self-help can be a useful start, but it does not replace medical advice or treatment when drinking has become heavy or hard to control.
Do not stop suddenly after heavy, long-term drinking without medical advice. Withdrawal can be dangerous and, in some cases, life-threatening. The NHS advises speaking to a GP so that withdrawal can be managed safely, sometimes with medication.
Notice what you are drinking for. A simple record of when you drink, how you feel beforehand and how you feel the next day can reveal patterns, such as drinking mainly when stressed, bored or lonely.
Build other ways to meet those needs. Regular physical activity has good evidence for easing anxiety and low mood, as covered in our piece on how exercise affects anxiety and depression; slow breathing, time outdoors, supportive company and structured problem-solving can also help.
Let a trusted person know what you are trying to do. Social support makes change easier, and it is harder for old habits to return quietly when someone else is aware of your goals.
Expect that mood and anxiety may feel worse for a short time before they improve, especially if alcohol has been a main coping tool. Sleep can take a while to settle too. This is a reason to have support in place, not a sign that change is failing.
When to talk to a professional
It is worth speaking to a GP, primary care doctor or mental health professional if drinking is affecting your mood, sleep, relationships or work, if you have tried to cut back and found it hard, or if you are drinking to manage symptoms of anxiety or depression.
Effective help exists. NIAAA’s guide to treatment for alcohol problems describes behavioural therapies, medications approved for alcohol use disorder and mutual-support groups, which can be combined. When anxiety or depression is also present, addressing both together usually works better than treating one alone.
Tell any prescriber that you drink, even if you think it is not much. Alcohol can interact with many medications, and combining it with sedatives such as benzodiazepines, sleeping pills or opioids can dangerously slow breathing.
In the US, the SAMHSA National Helpline (1-800-662-4357) offers free, confidential treatment referral and information, 24 hours a day. Alcohol can also lower inhibitions and increase impulsivity, which raises risk during a crisis: if you are having thoughts of suicide or self-harm, in the US call or text 988; in the UK and Ireland call Samaritans on 116 123. In an emergency, call your local emergency number.
Common questions
Is “hangxiety” a real thing?
It is not a formal diagnosis, but feeling anxious after drinking is widely reported and fits what is known about how the brain rebounds once alcohol wears off. Poor sleep, dehydration and worry about the night before can all make it stronger.
Can drinking cause depression, or does depression cause drinking?
Both can happen, and they often reinforce each other. A clinician can help untangle the pattern, often by looking at how mood changes after a period without alcohol.
Will my anxiety get better if I stop drinking?
Many people find that anxiety and sleep improve after cutting back or stopping, though the first weeks can be uncomfortable. If anxiety continues, it may reflect a separate anxiety condition that deserves its own assessment and treatment.
Is it safe to drink while taking antidepressants or anti-anxiety medication?
This depends on the specific medication and your health, so ask your prescriber or pharmacist. Alcohol can worsen side effects such as drowsiness and may make treatment for mood less effective.
The bottom line
Alcohol can bring quick relief from tension, but the same effects that calm you in the moment can leave you more anxious, lower in mood and less rested afterwards. Over time, drinking to cope can keep anxiety and depression going.
If you recognise yourself here, treat that as useful information rather than a verdict. Noticing the pattern, talking honestly with a professional and getting support to change safely are realistic steps, and treatment for both alcohol problems and mental health conditions helps many people.
