What causes a hangover exactly?

190 viewsBiologyOther

How come if I go to sleep after drinking, I wake up with cotton mouth and other symptoms, but if I just stayed awake none of that happens? Even if I don’t drink water or electrolytes during the time I’m awake.

Is it just a case of the body slowly adapting while awake vs. kind of “shocked” between two states when I sleep and wake up?

All the above is true but I will add that alcohol is a vaso dilator which in your body isn’t that big of a deal but in your brain the day after definitely is. Now the question is why not if u stay awake? To be honest i don’t know the answer other than humans brains be mad complicated
