In brief

Alcohol affects many parts of the body. Australian guidelines advise healthy adults to have no more than 10 standard drinks a week and no more than 4 on any one day.

  • healthdirect suggests stopping alcohol at least 4 hours before bed.
  • For blood pressure, healthdirect suggests no more than 2 standard drinks a day for males and 1 for females.
  • Drinking a lot of alcohol, especially beer and spirits, raises the risk of gout.

How it works

One standard drink contains about 10 grams of alcohol. Alcohol is filtered through the liver, and drinking too much is a common cause of fatty liver and of cirrhosis. Drinking more than recommended also raises the risk of high blood pressure.

Alcohol can disrupt your sleep cycles, leading to poorer quality sleep, and drug and alcohol use can be both a cause and a consequence of depression. The guidelines advise not drinking if you are pregnant, planning a pregnancy or breastfeeding.
