It can be easy to lose track of how many drinks you’ve had, especially when you’re out with friends or celebrating something big. But knowing what binge drinking is, why it happens and the effects it has on your body can help you to stay safe and in control.

Lots of people drink to celebrate, socialise or relax. But sometimes, a few drinks can turn into a few too many, and you might end up drinking a harmful amount without meaning to. This is called binge drinking.

Understanding your reasons for drinking heavily, and the risks involved, can help you to make choices that feel right for you. 

What counts as binge drinking?

Australian government guidelines recommend no more than four standard drinks on any one day, to reduce the risk of alcohol-related harm.

Binge drinking is when you drink more than this. It’s different from alcoholism, which usually involves a dependence on alcohol and drinking more regularly. It’s about consuming a lot of alcohol in a single session, which can happen for lots of different reasons.

Why you might binge drink

There are many reasons why you might drink more than you planned to. Recognising your own patterns can help you to change them. Here are some common reasons.

To boost a good time

Our culture often links drinking more with having more fun. But the fun can stop pretty quickly when you lose control or become drunk, or when you have to deal with the hangover, memory loss or regrets the next day.

To manage social anxiety or difficult feelings

It can be tempting to have a few drinks to ‘take the edge off’ in social situations. While it might make you feel more confident in the short term, alcohol can often make anxiety or low moods worse in the long run.

To fit in or because of peer pressure

When everyone around you is drinking, it can feel easier to just go along with the crowd. But if your friends are pressuring you to drink, it might be worth thinking about whether those friendships are healthy for you.

Forgetting to pace yourself

The line between having fun and drinking a risky amount can get fuzzy. You might start the night with good intentions, but then lose track. Slowing down and having a non-alcoholic drink in between alcoholic ones can make a big difference.
