Why do you get hangover?
In: Biology
Ethanol is essentially a poison that we can tolerate up to a certain amount. Ethanol particles are really small and when they pass through our brain cells, it interferes with their ability to talk to each other. Ethanol is also diuretic, meaning it makes us pee more (just like coffee) which causes dehydration.
So, it’s mainly the dehydration that causes the headache that comes with a hangover. Other than that, your body is trying to break down and expel the poison.
