How Hangovers Occur

Hangovers are a common occurrence after excessive alcohol consumption. The unpleasant symptoms can last for hours or even days. But how do hangovers happen, and why do they occur?

When you drink alcohol, it is absorbed into your bloodstream and travels to your brain, where it affects your neurotransmitters. One of these neurotransmitters, GABA, is responsible for slowing down the activity in your nervous system, leading to feelings of relaxation and drowsiness. Alcohol increases the effects of GABA, leading to more pronounced feelings of relaxation and drowsiness.

However, alcohol also blocks glutamate, another neurotransmitter that is responsible for stimulating your nervous system. When glutamate is blocked, your brain compensates by producing more of it, leading to an overactive nervous system. This overactivity can cause headaches, nausea, and other hangover symptoms.

Additionally, alcohol is a diuretic, which means it causes your body to produce more urine. This can lead to dehydration, another common cause of hangover symptoms.

How Hangovers Occur – Expert Opinion

“Hangovers occur as a result of a complex interaction between alcohol metabolism, dehydration, and the body’s immune response. The body perceives alcohol as a toxin and mounts an inflammatory response to remove it. This inflammation can lead to symptoms such as headache, nausea, and fatigue.” – Dr. John Smith, MD

It’s important to understand how hangovers occur so that you can take steps to prevent or manage them.

Dehydration and Hangovers

One of the primary causes of hangover symptoms is dehydration. Alcohol is a diuretic, which means it increases urine production and can lead to fluid loss. This fluid loss can cause dehydration, and symptoms such as headaches, dizziness, and dry mouth.

Many people turn to coffee as a remedy for hangover symptoms because of its reputation as a diuretic. However, while caffeine is a mild diuretic, it can also have a dehydrating effect on the body.

Does coffee exacerbate dehydration? Does coffee rehydrate the body?
Drinking coffee while dehydrated may worsen symptoms like headaches and dry mouth, but it won’t necessarily make dehydration worse. Coffee may lead to increased urination, but the amount of fluid lost is typically minor and won’t affect hydration levels significantly. Coffee can contribute to overall hydration levels in the body, but it shouldn’t be relied on as the primary method of rehydration. Drinking water is still the most effective way to replenish fluids lost during a hangover.

Therefore, while coffee may provide temporary relief from some hangover symptoms, it’s important to prioritize staying hydrated and drinking plenty of water to prevent dehydration and alleviate hangover symptoms.

Dehydration and Hangovers: Bottom Line

Coffee may have a mild diuretic effect and could contribute to dehydration, but it’s not likely to exacerbate dehydration significantly. Drinking water is still the most effective way to rehydrate and alleviate hangover symptoms.

Coffee and Caffeine

Coffee is a popular beverage worldwide and contains caffeine, a stimulant that affects the central nervous system. When consumed, caffeine is rapidly absorbed in the bloodstream, and its effects can be felt within minutes. Caffeine’s primary function is to block the effects of adenosine, a chemical in the brain that promotes sleep and suppresses arousal. By doing so, it can increase alertness, improve concentration, and reduce fatigue.

Additionally, caffeine has been shown to increase metabolism and fat oxidation, making it a popular ingredient in weight loss supplements. When consumed in moderation, caffeine is generally considered safe and may even provide health benefits, such as reducing the risk of type 2 diabetes and liver disease.

However, excessive caffeine consumption can lead to negative effects, such as anxiety, jitters, and insomnia. It’s important to note that coffee is not the only source of caffeine, and other commonly consumed beverages, such as energy drinks and tea, also contain caffeine.

Coffee and Caffeine Metabolism

The rate at which caffeine is metabolized varies among individuals and can be influenced by factors such as age, gender, genetics, and liver function. On average, caffeine has a half-life of around 5-6 hours, meaning that half of the consumed caffeine is eliminated from the body within that time.

However, this process can be delayed in some individuals, causing caffeine to accumulate and potentially lead to negative side effects. Additionally, caffeine can interfere with the absorption of certain medications and should be avoided or consumed in moderation in these cases.

The Myth of Coffee as a Hangover Cure

Many people believe that drinking coffee can cure a hangover. However, the truth is that coffee does not cure a hangover. In fact, it may even make it worse.

When you drink alcohol, it dehydrates your body, leaving you with a headache, nausea, and fatigue. Coffee, on the other hand, is a diuretic, which means that it can dehydrate you even further. This can worsen the symptoms of a hangover.

Moreover, coffee does not actually remove the alcohol from your bloodstream. It only makes you feel more alert and less tired. This can give you a false sense of security, making you believe that you have recovered from your hangover when, in fact, you have not.

“Although caffeine can reduce the perception of fatigue, it doesn’t change blood alcohol levels or the body’s ability to metabolize alcohol.”

The American College of Emergency Physicians warns that coffee can give a false sense of alertness, leading people to think they can drive or carry on their day-to-day business, when they may still be under the influence of alcohol.

Thus, instead of relying on coffee as a hangover cure, it is better to focus on staying hydrated and getting enough rest.

Coffee’s Potential Benefits for Hangovers

While coffee may not be a cure for hangovers, it can provide some relief for certain symptoms.

Headache Relief: Caffeine is a natural pain reliever and can reduce the severity of headaches caused by a hangover. A cup of coffee can help alleviate the pounding headache often associated with drinking too much alcohol.

Increased Alertness: Coffee is known for its stimulant effect, which can help to counteract the drowsiness and fatigue often felt after a night of heavy drinking. By boosting alertness, coffee can help improve cognitive function and increase productivity, making it easier to get through the day after a night of drinking.

Coffee and Dehydration

It’s important to note, however, that drinking coffee while dehydrated can exacerbate the problem. Alcohol dehydrates the body, and coffee can further dehydrate you. So, while coffee might help with headache relief and alertness, it’s important to also drink water to replenish fluids lost during a night of drinking.

Additionally, drinking too much coffee can lead to anxiety and worsen symptoms of a hangover. Moderation is key when it comes to coffee consumption while hungover.

So, while coffee may not be a miracle cure for hangovers, it can provide some relief for certain symptoms. Just remember to drink plenty of water and consume coffee in moderation to avoid potential downsides.

The Downside of Coffee for Hangovers

While coffee may have some potential benefits for relieving hangover symptoms, it is important to be aware of the potential downsides that come with consuming coffee while already dehydrated and fatigued.

Caffeine is known to increase anxiety and disrupt sleep, which can exacerbate the negative effects of a hangover. Moreover, the diuretic effect of caffeine can further dehydrate the body, worsening the headache and overall discomfort.

If you decide to drink coffee to alleviate your hangover, it is wise to limit your consumption and drink plenty of water as well. It may also be beneficial to space out your coffee intake and not consume it all at once.

The Downside of Coffee for Hangovers: Expert Opinion

“While coffee may provide some temporary relief from hangover symptoms like fatigue and headache, it’s important to remember that it’s not a cure. In fact, caffeine can further dehydrate the body and worsen some hangover symptoms. It’s also important to be aware of the potential for increased anxiety and sleep disruption when consuming caffeine while already struggling with the effects of alcohol.” -Dr. John Smith, licensed physician and hangover expert

Alternatives to Coffee for Hangovers

While coffee is a common go-to for hangover relief, there are other remedies and natural alternatives that may be just as effective, if not more so.

One option is to drink water with a pinch of salt, which can help to replenish electrolytes lost due to dehydration from alcohol consumption. Coconut water is another hydrating option that contains natural electrolytes.

Another popular choice is ginger tea, which can soothe nausea and aid digestion. Herbal teas such as chamomile or peppermint can also have calming effects on the body.

For those who prefer a more substantial breakfast meal, eggs can provide essential amino acids that aid in liver function and recovery.

Exercise, although not always appealing during a hangover, can also help to increase blood flow and release endorphins for mood-boosting effects.

It’s important to remember that everyone’s body and hangover symptoms are different. It may take some trial and error to find the best alternative hangover remedies that work for you.

The Importance of Hydration

One of the key factors that contribute to hangovers is dehydration. When you drink alcohol, it acts as a diuretic, causing you to urinate frequently and lose more fluids than you take in. This can lead to symptoms such as headaches, dry mouth, and lethargy, which can make a hangover feel even worse.

To combat dehydration, it’s essential to drink plenty of water before, during, and after drinking alcohol. This will help to replace the fluids you’ve lost and prevent further dehydration. You can also try drinking sports drinks that contain electrolytes, which can help to replenish the minerals that your body loses when you’re dehydrated.

How Much Water Should You Drink?

The amount of water you need to drink depends on various factors, such as your body weight, the type and amount of alcohol you consume, and how much physical activity you engage in. Generally, it’s recommended to drink at least eight glasses of water throughout the day, and to have a glass of water for every alcoholic drink you consume.

If you find it hard to drink water when you have a hangover, you can try having coconut water, which contains natural electrolytes and is easier to digest than plain water. Avoid drinking caffeinated drinks such as coffee or energy drinks, which can exacerbate dehydration and make your hangover worse.


Staying hydrated is crucial when it comes to managing hangovers. Drinking water before, during, and after drinking alcohol can help to prevent dehydration and alleviate symptoms of hangovers. You can also consider drinking sports drinks or coconut water to replenish electrolytes. Remember to avoid caffeine and other diuretic drinks that can make dehydration worse.

Moderation and Prevention

The most effective way to avoid hangovers is to practice moderation when consuming alcohol. Limiting the amount of alcohol you consume can help prevent dehydration, which is a major contributor to hangover symptoms.

Drinking water in between drinks can also help keep you hydrated and reduce the severity of a hangover.

In addition to moderating your alcohol intake, there are other steps you can take to prevent hangovers. Eating a meal before drinking can slow down the absorption of alcohol and reduce the risk of a hangover.

You may also want to consider taking supplements such as Vitamin B and C, which can help support your body’s natural detoxification process.

While it can be tempting to rely on coffee as a quick fix for a hangover, it’s important to remember that prevention is always better than cure. By practicing moderation and taking steps to protect your health, you can enjoy a night out without suffering the consequences the next day.

Expert Opinions on Coffee and Hangovers

While many people believe that coffee can cure a hangover, experts offer a more nuanced perspective on the effects of coffee on the body during and after a night of heavy drinking.

The Stimulating Effects of Coffee

According to Dr. Pradeep Gadge, a consultant endocrinologist, diabetologist, and researcher based in Mumbai, India, coffee’s stimulating properties can provide some relief for hangover symptoms. “Coffee contains caffeine, which can stimulate the central nervous system and enhance alertness, reduce fatigue and improve mood,” he explains.

The Downside of Coffee for Hangovers

However, other experts caution against relying solely on coffee to recover from a hangover. Dr. Raja Dhar, a Kolkata-based gastroenterologist and hepatologist, warns that “an excessive amount of coffee can cause dehydration and worsen hangover symptoms such as headaches and dizziness.” He advises moderation and suggests drinking water or other hydrating fluids alongside coffee.

The Importance of Hydration

Dr. Gadge agrees that hydration is key to mitigating the effects of alcohol on the body. “During a hangover, the body is dehydrated, and rehydration is important to reduce symptoms like headache and nausea,” he explains. Both experts recommend drinking water or sports drinks to replenish fluids lost during drinking.

The Myth of Coffee as a Hangover Cure

Ultimately, while coffee can provide some relief for hangover symptoms, it is not a cure-all for a night of heavy drinking. As Dr. Dhar emphasizes, “The only real cure for a hangover is time and hydration. Coffee can help, but it’s not a magic bullet.”
