How alcohol impacts mental health

There’s a famous line in the legendary cartoon series ‘The Simpsons’ where Homer’s friend and drinking buddy Lenny says: “Nothing like a depressant to chase the blues away!”

While many of us associate drinking alcohol with celebrating or having a good time with friends or family, it’s important to remember that alcohol is a depressant and, over time,  alcohol consumption has negative effects on the body and brain.

There have been studies showing the benefits of alcohol consumption. From a physical side, in moderation, some studies suggest it may:

  1. Reduce your risk of developing and dying of heart disease
  2. Reduce your risk of stroke
  3. Reduce your risk of diabetes

From a mental health aspect, low and moderate doses of alcohol have been shown to increase:

  1. Affective expression
  2. Happiness 
  3. Euphoria
  4. Conviviality (the quality of being friendly and lively)
  5. Pleasant and carefree feelings

However, some of these claims are disputed, including by the World Health Organisation, who advise that any alcohol consumption can have negative impacts on physical and mental health. What has also been proven are the negative effects alcohol can have on our lives – from death to damage to mental functioning and loss of relationships – especially if you drink too much of it.

According to the Australian National Alcohol & Drug Knowledgebase (NADK):

  • 5% of Australians drink alcohol every day and 
  • 7% drink 5-6 days per week.

It’s at these levels where alcohol can have a really damaging impact on people’s physical and mental health.

How alcohol affects our brain chemistry and mental health

The brain relies on a delicate balance of chemicals and processes and, ultimately, alcohol disrupts this balance. More specifically, alcohol affects the part of your brain that controls inhibition, so after a few drinks you may feel relaxed, less anxious and more confident, but these positive feelings quickly wear off. These short-term chemical changes in your brain can later lead to more negative feelings such as anger, depression or anxiety in the long term.

Alcohol also slows down how your brain processes information, making it harder to work out true feelings and the possible consequences of our actions. Over time, alcohol uses up and reduces the number of neurotransmitters in our brains, depleting important resources needed to ward off:

1) Anxiety
For someone experiencing anxiety, a drink might help them feel more at ease initially, but these effects wear off fast. Relying on alcohol to mask anxiety could also lead to a greater reliance on it to relax. A likely side-effect of this is the increased risk of building up a tolerance to alcohol. Over time you will need to drink more alcohol to get the same feeling. And, in the medium to longer term, this pattern often leads to alcohol dependence. Furthermore, regular hangovers can also exacerbate feelings of anxiety, leading to people wanting to drink again to ‘ease’ their feelings.

2) Depression
For depression, drinking regularly can cause a similarly vicious cycle, although it can be difficult to separate cause and effect. This means it’s not always clear whether drinking alcohol causes a person to experience symptoms of depression. What we do know is that depression and heavy drinking have a mutually reinforcing relationship – meaning that either condition increases a person’s chances of experiencing the other – and that alcohol affects several nerve-chemical systems within our bodies, which are important in regulating our mood. Numerous studies have confirmed that drinking heavily impacts our moods while eliminating drinking can improve them.

Tips to cut down alcohol consumption

Stop alcohol concept. Person refuse to drink alcohol.

If you’re concerned about how much alcohol you’re having on a regular basis, there are numerous things you can do to help curb your consumption, including: 

  1. Drinking soft drinks between alcoholic drinks.
  2. Have designated days of the week when you won’t drink.
  3. Switch to lower-strength or alcohol-free drinks.
  4. Keep a diary of your drinking and check in with it every few weeks to track how you’re doing.
  5. Make sure you’re not drinking on an empty stomach.
  6. Stay within the Australian government’s weekly consumption guidelines (10 standard drinks). 

Healthier ways to relax

If you’ve been having a drink most days as your way to relax, it can be hard to break that habit. So, start by aiming to have just one small drink with your dinner in the evening. Try to resist the temptation to reach for the bottle as soon as you get home. There are also numerous other activities to do instead of drinking to help you relax, including: 

  1. Doing some exercise. This could be a class, a run on the treadmill or simply a brisk walk.
  2. Practising yoga or stretching. Put on some calm music and move and stretch your body, gently and slowly. Breathe deeply while you do this.
  3. Listen to some calming music.
  4. Cooking can also be a calm and relaxing activity for some people. Try a new recipe or make time to create your favourite meal.
  5. Have a relaxing bath. Use essential oils, candles and bubbles to connect and stimulate all your senses.

Can I drink if I am feeling depressed or anxious?

If you struggle with depression and anxiety, or other mental health problems, but would like to drink, it’s best to discuss the subject with your doctor, or with someone at your local alcohol service. Some people find that it’s best for them to stop drinking for an extended period or altogether in order to improve their symptoms.
