Alcohol and Anxiety: Which Comes First?
You pour a drink to take the edge off. Maybe it's been a stressful day, or anxiety has been building all week. For a while, it seems to work. But over time, many people notice something troubling: the very thing they turned to for relief seems to be making everything worse. So which comes first, the drinking or the mental health problem? The honest answer is often, both.
A Very Common Combination
The overlap between alcohol use and poor mental health is well-documented in the UK. Research published by Alcohol Change UK in 2024 found striking differences between drinking levels and reported depression. Fewer than one in five (18%) of people who never drink report depression — compared to more than one in four (26%) of hazardous drinkers, and nearly four in ten (37%) of harmful drinkers. That's not a small gap; it's a significant trend.
It's also a deeply relatable one. A survey commissioned by Alcohol Change UK found that over half of people who drink (53%) said they had done so for a mental health reason (such as feeling anxious, stressed or worried, or having trouble sleeping) at least once in the previous six months. Alcohol has been described as the UK's favourite coping mechanism, and it's not hard to see why. It's legal, widely available, socially encouraged, and offers fast, if temporary, relief.
The Problem With Using Alcohol to Cope
Alcohol is a depressant. That means that while it can reduce feelings of anxiety in the short term by slowing down the nervous system, the longer-term effect is the opposite. Regular drinking disrupts the brain's chemistry. These are the very systems that regulate mood, sleep, and stress response and so drinking will automatically leave people more vulnerable to anxiety and low mood after they’ve stopped drinking.
The same Alcohol Change UK survey found that four in ten people (44%) said drinking had made their mental wellbeing worse, reporting increased anxiety, trouble sleeping, memory issues, sadness, or irritability. Hangovers are particularly cruel in this regard. The headache and nausea are familiar. Less talked about is the anxiety and low mood that often accompany them, sometimes called 'hangxiety', which can persist for hours or even a full day after drinking.
This creates a cycle that can be difficult to escape. People drink to manage anxiety, sleep better, or lift their mood. When the alcohol wears off, those symptoms return - often heightened. So they drink again. The underlying issues never get addressed, and the reliance on alcohol quietly deepens.
So Which Comes First?
The British Psychological Society has described this as a 'chicken and egg problem' and it genuinely is. For some people, anxiety or depression comes first, and alcohol becomes a way of managing it. For others, heavy drinking precedes and triggers mental health difficulties. For many, the two develop together, each making the other worse.
NHS data from the Adult Psychiatric Morbidity Survey confirms that alcohol misuse often co-exists with common mental disorders such as depression and anxiety, and that this combination can complicate both diagnosis and treatment. The good news is that clinicians are increasingly recognising the need to treat both at the same time, rather than insisting one must be resolved before addressing the other.
What This Means in Practice
If you're drinking to cope with how you're feeling, it's worth knowing that you're far from alone and that what you're experiencing is not a character flaw. The relationship between alcohol and mental health is complex, and for many people, cutting back on drinking leads to a noticeable improvement in mood, sleep, and anxiety levels within just a few weeks.
Talking to a GP is a practical first step. In the UK, NHS Talking Therapies offers free access to evidence-based support for anxiety and depression and alcohol doesn't have to be 'under control' before you seek help with how you're feeling. Both can, and should, be addressed together.
