Dehydration is the main reason you're left with a sensitive head in the morning. The nausea is generally caused by a low blood sugar level, and you're usually irritated because alcohol is a depressant drug.

The main cause of a hangover is the effect of ethanol – the alcohol in your drinks. It's a toxic chemical that works in the body as a diuretic, which means it makes you pee more and you can become dehydrated as a result.
