What are the Causes of a Hangover?
A hangover occurs after drinking a lot of alcohol. When you drink alcohol, it metabolizes quickly in your body, entering your bloodstream and causing your pituitary gland to stop the production of vasopressin.
Vasopressin is an anti-diuretic hormone, and without it, your body expels the majority of liquids you consume, rather than absorbing them. In fact, drinking 250 ml of alcohol can cause your body to expel about 800 ml of liquid, thereby making you become dehydrated quickly.
The expelled liquids contain vital electrolytes like potassium and sodium. Losing these nutrients disturbs muscle, nerve, and overall cellular function. In addition, a depletion of potassium and sodium can result in headaches, nausea, and other hangover related symptoms.
Alcohol also causes the glycogen in your liver to break down. Glycogen is an essential carbohydrate that, while drinking, is turned into glucose and expelled from your body. The absence of glycogen causes fatigue and weakness associated with a hangover.
Fatigue is also, in part, due to your body’s increased production of glutamine after drinking alcohol. Glutamine decreases your ability to sleep deeply, so even if you sleep several hours after intoxication, you will probably still wake up tired.
Dehydration due to alcohol also causes your thirsty organs to steal water from your brain. This causes your brain to decrease in size, making your brain’s membranes tighten and pull, causing additional head pain during a hangover.
Now that you know that dehydration is the root of your hangover pains, the best thing to do to relieve a hangover is to rehydrate. It’s also important to keep in mind that rehydrating also means replenishing your body’s electrolyte content.
So, instead of reaching for the tap, grab an electrolyte-rich beverage.
What’s an electrolyte-rich beverage?
An electrolyte-rich beverage is any isotonic beverage that replaces fluids and minerals that your body loses during intoxication or physical activity. Isotonic beverages may include sports drinks, but unfortunately, sports drinks are also high in calories, sugars, and additives.
Coconut water provides your body with more essential electrolytes like potassium than any sports drink. Best of all, coconut water is low in calories, is fat-free, and contains zero additives.

Thanks for the advice. Will definitely take it into consideration!
I’ve always had Vitamin Water to cure my hangover. After reading this article and seeing all the benefits of Phenom Water, I would much rather drink that after a long night of drinking instead of Vitamin Water which there is much debate on whether it is healthy for you or not.
Usually my hangovers consist of a headache and a tummy-ache. I end up pumping my body full of water just to get it rehydrated. Thanks for the info about rehydrating with an electrolyte-rich beverage (like Phenom!). I’ll definitely try it out next time…
I really want to give this a try. Years ago I could go out and drink and feel fine the next day but as I’ve gotten older I really feel dehydrated after a night on the town! I am exited to try it out!
I deffenetly could use some of this for this weekend. It is always hard to find something that makes that pounding headache go away and it sounds like this will be very tasty too. i hope there is not too much sugars in it. i am diabetic
thanks

Good stuff- who would have thunk?!
Will try as well!
I’ve always used coconut on my skin but never thought about drinking! DUH..if it does wonders on my skin i can only imagine what it can do for my inner body!!!! Definitely looking forward to drinking coconut water and seeing the great benefits!
I too have been drinking Vitamin Water for a hangover. I get ridiculous hangovers, and nothing works! I’m excited to try this, and would love to report back!
My friends always suggest having some “hair of the dog” for a hangover, but this makes a lot more scientific sense to me….also sounds healthier on my liver! Will definitely give it a try the next time I wake up and realize I’ve had a little more than I should have
The problem with drinking is that your bloodstream is full of alcohol.It is because you are expelling the “water” that should be in your bloodstream. On the other hand it’s because alcohol is going in vs. the water you should be drinking. Solution is to dilute the alcohol in blood stream in the first place. I have hear that some premed students hook up to IV and they can’t feel a thing the next day. I guess coconut water would be the best option for us who don’t have that luxury. I also like that you guys have then 100% natural pure version, so we won’t be pouring “chemicals” into our body when it’s already traumatized.
I love coconut water and it’s my beverage of choice for re-hydration the next morning. It’s also great when you’re sick and water just doesnt taste good.
Wow, this is great information! I just knew there had to be some product out there that would replenish your body after a night out and this seems perfect!
I get terrible nausea and vertigo the day after. I never really get a headache. I’ve always used gatorade to help with my hangovers. I’m excited that this alternative is 100% natural. I love trying to eat as many natural foods as possible.
My roommate started has been raven about an incredible healthy drink as she is a health freak. She has stocked our refrigerator up with Vita Coco, I had a huge hangover this morning so I grabbed one and wow what an amazing drink. The coconut water cured my hangover in less than half an hour. So I started doing some research on where to buy the incredible beverage and came upon this website. I hope my comment gets picked so I can try this Phenom brand and do a comparison.
I’ve had hangovers for the last 25 years!! I’ve tried many things such as aspirin, lots of water, coffee, tea, hair of the dog to no avail. I’m happy to hear that coconut water is such an asset to the hangover cure. I’m looking forward to trying this. I’ll tell all my friends how great this product is for a hangover and overall good health. Thanks.
I actually don’t ever get hungover (haha, please don’t hate me), but I do drink water like it’s my job the morning after a night out. My brother, on the other hand, nurses a gatorade for hours when he wakes up hungover. I wonder if I could talk him into coconut water instead…
I always thought gatorade was the hangover cure when I was sick in the morning. A friend told me about coconut water and it changed my prespective!!! It definitely works the next morning faster than anything I have tried in the past!
I always heard that you have to rehydrate in order to get over a hangover Sports drinks are so full of high amounts of sugar its really not good to drink them I am glad to hear that coconut water can help . I am a huge fan of coconut naturally and with all the added vitamins and it being more natural approach I will be trying this the next time I wind up hungover !
This sounds like a way better alternative then some “sugary drinks” or basically water with a miniscule amount of vitamins. I am very curious to try this, as I drink a lot of water right after a heavy drinking night and when I wake up.
It’s true. I get nauseus if I drink regular water the morning after partaking. This went down easily, and I felt refreshed soon after drinking it. Love the stuff!
always on the look out for new remedies. will try soon!!:)
