Introduction to Alcohol and Health

What Alcohol Does to Your Body

Alcohol is a psychoactive substance that affects almost every system in the human body. Once consumed, it enters the bloodstream and is primarily processed by the liver. On average, the body metabolises one standard drink per hour. Anything beyond this remains in circulation, impacting organs such as the brain, heart, and digestive system.

Alcohol Consumption in Australia

According to the Australian Institute of Health and Welfare, one in four Australians aged 18 and over exceeds the National Health and Medical Research Council’s (NHMRC) safe alcohol guidelines on a single occasion. This highlights the importance of awareness and education around alcohol-related risks.
