Dehydration from alcohol
Dehydration from alcohol

Drinking too much alcohol at night can certainly wreck your morning. Alcohol can irritate blood vessels, leading to a ‘hangover headache’ – migraine-like symptoms of throbbing pain and nausea. To avoid a hangover headache, stick to moderate drinking. According to the Australian National Health and Medical Research Council, moderate drinking in healthy men and women is no more than ten standard drinks a week and no more than four on any one day. Of course, the less you drink, the lower your risk of headaches and harm from alcohol.

So, what’s a standard drink?

A standard drink equals ten grams of alcohol, regardless of glass size or alcohol type, and is most likely a whole lot less than what you think it is.

For example, a standard glass of white wine (11.5% alc/vol) is 110mL – that’s about one third of most wine glasses (300mL).
A standard glass of bubbly (12% alc/vol) is about half a champagne flute.
While a full-strength beer or regular cider (4.9% alc/vol) is 260mL – that’s less than most cans and small bottles, which are typically 375mL and equal to 1.4 standard drinks.
