In recent years, drinkers have become more aware of the health dangers of drinking alcohol, from disease to risky behaviour and poorer wellbeing. Events like the just-finished Dry July, Febfast and Hello Sunday Morning — when people voluntarily abstain from alcohol for periods of time — are growing in popularity and raise awareness about the risks involved in overindulgence.

Many people extend these alcohol-free periods throughout the year by incorporating alcohol-free days into their weekly routines, while still enjoying a drink on the weekends.

But does drinking the same amount spread over the week versus just on the weekends, make any difference health-wise?

How much is too much?

Australian alcohol guidelines and the World Health Organization state there is no safe level of alcohol use. For adults who do drink, the guidelines recommend a maximum of four drinks in one sitting or ten in a week. (A zero-alcohol approach is recommended for under-18s and during pregnancy.)

For some, this may not sound like much at all. One in four Australians exceed the recommendation of no more than four drinks in one session, with men more likely to do so than women. This amount can result in alcohol poisoning, damage to brain cells and a higher likelihood of engaging in risky behaviours leading to violence, accidents and unprotected sex.

But what about a wine each night?

Even abiding by the Australian alcohol guidelines and drinking in moderation — one or two drinks each day over the week — can be risky. Possible health outcomes of moderated drinking include increased risk of cancer, liver and heart disease, alcohol use disorder, and an increase in the symptoms of anxiety and depression.
