Everything we know about hangovers - and what you can do to make the pain go away


Happy New Year and welcome to 2017!


Many of us may not be feeling the welcome just quite yet. After all, Newton's third law states that for every action there is an equal and opposite reaction.

And while he was talking about physics, not biology, it certainly feels like hangovers follow that law, though we might rephrase it as "for every moment of inebriated exhilaration, there is an equal and opposite feeling of pain and unease."

But what is it about throwing back a few too many that leaves you feeling only halfway human: your head throbbing, your mouth dry, your stomach on edge? Could that feeling really be explained by dehydration, as so many seem to think? Even more important, is there a cure to hangovers?

Unfortunately - spoiler alert - the answer to the cure question is no. And as for dehydration, it's not the main culprit, hangovers are more complicated than that. In fact, much about hangovers is still a mystery to scientists. But here's what we know.


And just a note: We're looking at hangover symptoms specifically here, not the effects of long term alcohol abuse. Frequent hangovers could be a sign that you should consider cutting back on drinking.
