Your bar tab isn’t the biggest price you pay for over imbibing. Finnish research shows that intoxication can raise your stroke risk. In the 16-year study, men who were hit with one or more hangovers a year were 2.3 times as likely to experience a stroke as those who’d never been hungover. As you process excess booze, your blood pressure spikes, raising your risk of a brain attack, notes study author Dr Sudhir Kurl.
