Even after one evening of drinking, the body is left in a withdrawal state for 24 hours.
You can’t say we didn’t warn you (What does binge drinking do to your body?). If you are feeling hungover (dehydrated? demotivated? depressed?) after a day of binge drinking, this is the “why” and “how to recover” on the day after.
Being hung over is a place no one wants to be. The literal translation of the Swedish word for hangover is “kicked from behind”. The French describe themselves as waking with a “wooden mouth” or “hair ache”; while the Danes have “carpenters in the forehead”. The Germans and the Dutch say they have a, presumably wailing, “tomcat”. But why is it you feel so bad?
Dehydration
One 250ml glass of wine (or other alcohol) causes the body to expel 800 to 1,000ml of water. That’s four times as much liquid lost as gained, which explains the heavy traffic to the toilets in drinking establishments. Urinating this frequently expels salts and potassium, which are necessary for nerve and muscle function. When the levels get low the results are headaches, nausea and fatigue.
