A lot of people think that hangovers are "JUST DEHYDRATION", but not only is this not true, it's actually totally ridiculous. Even medical professionals try to sell us that line. I don't believe they are lying on purpose. Just like children, they are repeating what they have heard over and over again.
Why is a hangover being "just dehydration" so silly? All you have to do is think about it...
If you go for a long run, you get dehydrated.
Do you feel sick?
Do you feel like vomiting?
Big maybe...if you're really out of shape I guess, but...
Does it FEEL like a hangover.
Answer - NO!
If you lie on the beach all day, baking in the sun, (not great for your skin), but you do end up dehydrated, right?
Do you feel sick?
Do you feel like vomiting?
Do you feel HUNGOVER?
Answer - NO!
(Unless like me you put down 5 or 6 skinny margaritas, but then again I have a solution for that too!)
In fact, you might get a slight headache from dehydration or nausea, but for the most part, if you get physically ill from dehydration, you probably have heat exhaustion or heat stroke and are possibly close to having a serious medical problem - like DEATH for example.
Dehydration is only one of about a dozen or more physiological effects from alcohol. Yes, it's true that diuretics like ethanol trick our body into pumping out too much water.
But if beating hangovers were as simple as guzzling water or sports drinks, nobody would ever get them!
So why do they keep trying to sell us this BS line over and over and over...?
I'll tell you why... There are HUGE, POWERFUL COMPANIES that want to sell you crap.
What kind of crap?
Powerade, Gatorade, Pedialyte etc...
There's nothing inherently wrong with water, sugar and minerals, but it's not a miracle cure for anything.
In fact, pure H2O and nutritious foods provide all of the hydration you will ever need.
Nothing wrong with drinking these drinks. I do it myself.
Just know that if all you do is chug some Pedialyte, then you are ignoring 95% of the problem.
And worse, you are really only addressing one of the easiest parts of the hangover to solve.
