“Next, we asked respondents to rank their hangovers after an average night of drinking on a scale of zero (no hangover) to 100 (an extreme hangover). Physical symptoms of a hangover can include tiredness, headaches, sensitivity to lights and sounds, dehydration, muscle aches, increased blood pressure, a rapid heart rate, tremors, and sweating.
On average, men ranked their hangovers as slightly worse than what women experienced – even though research has found women may be more susceptible to the effects of alcohol. People in the military (active or retired) also ranked their hangovers as more severe than civilians, but participants in Greek organizations ranked their hangovers as roughly seven points more uncomfortable than those who weren’t in a fraternity or sorority.
People who had friends who suggested they might have a drinking problem had the worst hangovers of them all – ranking them a 52 on our scale of 100.”
