Alcohol and Dehydration
Fact 1: Alcohol acts as a diuretic (a substance that increases urine output)
Fact 2: For every standard drink you consume (10 mg of pure alcohol) you are likely to urinate 100 mL more than you drink, leading to dehydration
Fact 3: Headache, dry mouth, fatigue and dizziness are symptoms of dehydration
Fact 4: Hydralyte is an effective treatment of dehydration
The National Health and Medical Research Council (Australia) recommends that adult men and women drink no more than 4 standard drinks on any one drinking occasion. Above that number is considered excess and can increase the risk of health-related injuries.
Excessive alcohol consumption involving 6 to 10 standard drinks could therefore lead to a net fluid loss of 600–1000 mL or more, and therefore dehydration.
