Why do people who drink get a hangover?
Hangover symptoms vary between people, but they mainly involve sickness, headache and tiredness, feeling dizzy, thirsty, still feeling drunk the morning after, body and muscle aches, diarrhoea, bad breath, sensitivity to light and loud sounds, depression, and irritability
You might also experience elevated levels of anxiety, regret, shame, embarrassment, as well as depression.
How hung-over you feel will generally depend on how dehydrated you were before the drinking began, whether you drank plenty of water during the drinking session and how much sleep you got afterwards.
A hangover is the consequence of having consumed too much alcohol and is caused by dehydration. This is due to the ethanol in your drinks. This is a chemical that works in the body as a diuretic (removes water), so you wee more when you drink and become dehydrated.
