Hangovers vary from person to person, but usually involve a headache, nausea, tiredness and dehydration. Dehydration is one of the main causes of your hangover symptoms.
Alcohol increases the production of stomach acid and delays stomach emptying. Any of these factors can cause abdominal pain, nausea or vomiting. Alcohol can cause your blood sugar to fall. If your blood sugar dips too low, you may experience fatigue, weakness, shakiness, mood disturbances and even seizures.
Drinking plenty of water
Rehydrating the body by drinking water may help to improve the symptoms of a hangover. Alcohol is a diuretic, which means that it increases the amount of urine a person passes. The resulting loss in fluid can cause dehydration and electrolyte imbalances. These factors contribute to a hangover.
You Could Become Dehydrated
Not only can alcohol be toxic at high doses, but it is also a diuretic, which means it draws water out our body and is dehydrating. Hultin says this can lead to all sorts of symptoms, like headaches, nausea, vomiting and dry mouth.
Legend: Hangovers are related to a toxin released when your liver processes alcohol. When your body breaks down ethanol, it creates a particularly nasty byproduct called acetaldehyde. Studies in the early 2000s tied it to many hangover symptoms.
The symptoms of a hangover will peak when your BAC goes back to zero, around 12 hours after your drink.
So why do my hangovers feel worse every year? One popularexplanation as to why hangovers get worse as you move into your late 20s and 30s is that you lose some of the enzymes required to break down alcohol from acetaldehyde to nontoxic acetate.

Several strategies may help reduce the severity of hangovers. These include avoiding drinks high in congeners, drinking plenty of water, getting adequate sleep, and having a nutritious breakfast. But the best way to avoid a hangover is to drink in moderation or abstain completely.
Chugging large quantities of water isn't hydrating you any more than if you sip it slowly. It can seem like you're being proactive by gulping down a large amount of water before beginning some extraneous exercise.
In general, however, it usually takes about two hours for your body to rehydrate fully after drinking a significant amount of water. As for how you should rehydrate, water is the best choice.
"When you're hungover, you need to hydrate your body. The way you feel – that headache – it's mostly caused by dehydration. Something like Coca-Cola has lots of sugar and fluids and will put those back into your body to get your energy levels up. The caffeine will also give you an energy boost."
Throwing up naturally after drinking may help relieve symptoms of excess alcohol in the bloodstream. Generally, a person may feel better after throwing up the alcohol. If a person throws up shortly after drinking, the body may not have absorbed the alcohol, potentially lessening its effects.
While rum has a relatively small amount of methanol congeners (up to 131mg/L), it has about 3,633mg/L of propanol congeners, the highest amount of propanol of any alcohol on this list. For this reason, it can be one of the worst types of alcohol for a hangover.
For some people, as little as one drink can trigger a hangover. Other people seem to be able to get away with several drinks, or even a night of heavy drinking, without experiencing much in the way of next-day effects.
Dr Niall Campbell, consultant psychiatrist at Priory's Roehampton Hospital and one of the UK's leading alcohol addiction experts, says the idea that hangovers get worse with age is no myth - and has a lot to do with the body's changing metabolism, and prescription medications.
Drinking alcohol to excess can lead to a host of hangover symptoms, including throwing up. Vomiting is your body's response to excess toxins from alcohol in your body. While vomiting may make you feel awful, the risks from excess toxins can be damaging to your system.
"Lots of water" is one of the best ways to prevent or ease a hangover. An anti-inflammatory such as ibuprofen the next morning will give some relief in about 30 minutes, although be sure to take with some food to avoid stomach upset.
Typically, hangovers tend to go away within 24 hours. This is known as an all-day hangover, and will usually resolve on its own. That said, some hangovers can last even longer. Some hangovers, known as a two-day hangover, last anywhere from 48 to 72 hours.
Want to gain an edge over plain old water to treat your hangover? Consider reaching for Gatorade, Pedialyte, Powerade, or a similar nonfizzy sports drink. These drinks are packed with certain minerals called electrolytes — such as sodium, potassium, magnesium, and calcium — which help regulate fluid levels in the body.
Our ability to perceive the effects of alcohol diminishes after age 50.
Enzymes in your liver begin to process alcohol by breaking it down into acetaldehyde, a toxin commonly thought to be a contributor to hangover symptoms. From there, enzymes break the acetaldehyde down into non-toxic acetate. But, here's the thing: your liver can only do that so fast, and it gets slower as you age.
A hangover kind of works the same way. Not only does it cause changes to our immune system, it also increases cortisol levels (often called the “stress hormone”), blood pressure and heart rate – changes which also happen with anxiety.
