Do Energy Drinks Make Hangovers Worse? The Surprising Truth About the Caffeine and Alcohol Mix

4 min read

In 2013, a study found that people mixing alcohol and energy drinks (AMED) reported significantly worse hangovers than those who only drank alcohol. This phenomenon begs the question: Do energy drinks make hangovers worse? The answer lies in the complex and dangerous interaction between stimulants and depressants, and the side effects are more severe than you might think.

Quick Summary

Combining alcohol and energy drinks can intensify hangover symptoms. Caffeine masks the effects of intoxication, which leads to increased alcohol consumption, while both substances act as diuretics, worsening dehydration and contributing to a more severe next-day recovery.

Key Points

  • Masked Intoxication: The caffeine in energy drinks can hide the sedative effects of alcohol, leading people to consume more without realizing how intoxicated they are.

  • Intensified Dehydration: Both alcohol and caffeine are diuretics, meaning they cause increased fluid loss. Combining them leads to a severe dehydration double-whammy, worsening headaches and fatigue.

  • Higher Alcohol Intake: With masked intoxication, there's a higher risk of binge drinking and consuming more alcohol than you normally would, which is the primary driver of a bad hangover.

  • Synergistic Side Effects: Some evidence suggests a synergistic effect where the combination of alcohol and energy drink ingredients (like taurine and caffeine) intensifies impairment.

  • Sugar Crash: The high sugar content in energy drinks can lead to a blood sugar crash that compounds the effects of an alcohol hangover, causing additional fatigue and headaches.

  • Increased Health Risks: Beyond the hangover, mixing alcohol and energy drinks is linked to an increased risk of heart palpitations, insomnia, and higher rates of alcohol poisoning.

  • Slower Recovery: The combined effects place a greater strain on your body, particularly the liver, prolonging the recovery time needed to feel better.

The Counterintuitive Combination

Mixing energy drinks with alcohol is a popular but problematic combination. On the surface, the stimulant effect of caffeine and other ingredients in energy drinks seems to counteract the depressant effect of alcohol. People often consume this mix to stay awake and continue drinking for longer periods. However, this is a dangerous deception. Instead of canceling each other out, the two substances create a unique set of risks that make the aftermath far more brutal.

The caffeine in energy drinks stimulates the central nervous system, creating a feeling of alertness. This can mask the sedative effects of alcohol, like drowsiness and impaired judgment, which are natural cues for a person to stop drinking. Without these signals, individuals are more likely to drink beyond their normal limit, leading to a higher blood alcohol concentration and a significantly worse hangover.

The Dehydration Double Whammy

One of the most significant factors contributing to a severe hangover is dehydration. Alcohol is a diuretic, which means it increases urination and causes fluid loss. Unfortunately, caffeine is also a diuretic, compounding the dehydrating effect. When you mix the two, you're creating a double whammy of fluid loss, putting your body under extreme stress and exacerbating classic hangover symptoms.

Key dehydration symptoms that are intensified by this mix include headaches, dry mouth, and fatigue. The fluid loss also disrupts the body's electrolyte balance, which is crucial for proper nerve and muscle function. The resulting imbalance can lead to muscle cramps, further fatigue, and overall malaise, making a full recovery more difficult.

The Role of Sugar and Other Stimulants

Energy drinks are notoriously high in sugar, which can contribute to a different kind of crash. After the initial sugar rush that accompanies a sugary energy drink, your blood sugar levels can plummet, leading to a 'sugar hangover'. This can cause symptoms like headaches, brain fog, and fatigue, which are difficult to distinguish from an alcohol-induced hangover. When you layer an alcohol hangover with a sugar hangover, the result is a magnified feeling of misery.

Beyond caffeine, other ingredients like guarana, taurine, and ginseng are common in energy drinks. While the specific interactions of these ingredients with alcohol are less understood than caffeine, they can still contribute to a crash and worsen the next-day effects. The overall chemical cocktail can place a massive burden on your body and liver, which is already working overtime to process the alcohol.

The Masking Effect: A Dangerous Deception

The biggest risk of mixing alcohol and energy drinks is the masking effect. You feel more awake and alert, but your blood alcohol concentration remains the same, or even increases, as you drink more. This false sense of sobriety can lead to dangerous, high-risk behaviors that you might otherwise avoid, such as driving under the influence or engaging in risky sexual behavior. The combination is a fast track to binge drinking and an increased risk of alcohol poisoning.

Comparison: Hangovers with and without Energy Drinks

Feature Regular Alcohol Hangover Mixed Drink (AMED) Hangover
Dehydration Caused by alcohol's diuretic effect Significantly worse due to combined diuretic effects of alcohol and caffeine
Alcohol Consumption Drinking may be self-regulated by fatigue Alertness from caffeine can mask fatigue, leading to higher intake
Symptom Severity Unpleasant, but typically less intense Enhanced symptoms, including heightened headache, nausea, and irritability
Crash Effect General fatigue as alcohol wears off Severe "caffeine crash" or "sugar crash" on top of alcohol fatigue
Sleep Quality Disrupted sleep due to alcohol's effect on sleep cycles Further disrupted by caffeine, leading to poor sleep quality

So, Do Energy Drinks Make Hangovers Worse?

All evidence suggests that, yes, energy drinks significantly worsen hangovers. By masking the effects of intoxication, they encourage greater alcohol consumption and intensify the dehydrating effects on the body. The added stimulants and sugars place an even greater burden on your system, leading to a more painful and prolonged recovery. The temporary feeling of alertness is not worth the magnified and potentially dangerous consequences that follow. The best way to avoid a hangover is always moderation or abstinence, but avoiding energy drink cocktails is a simple step to prevent a much worse outcome.

How to Mitigate Hangover Symptoms

If you find yourself in the throes of a hangover, whether from mixed drinks or not, there are steps you can take to ease the symptoms and recover more quickly. While time is the only true cure, these strategies can provide some relief:

  • Rehydrate with water and electrolytes: As soon as you wake up, start drinking water. Replenish lost electrolytes with coconut water or a sports drink, but choose a non-caffeinated option to avoid further dehydration.
  • Eat a nutrient-rich breakfast: Stabilize your blood sugar with a balanced meal. Toast, eggs, and fruit are good choices. Avoid greasy junk food that can irritate your stomach.
  • Get more rest: Alcohol disrupts your sleep, so getting extra rest is crucial for your body's recovery. Nap if you can to let your system clear the toxins and heal.
  • Take a non-acetaminophen painkiller: For a headache, opt for ibuprofen or aspirin. Avoid acetaminophen (like Tylenol), as combining it with alcohol can be toxic to your liver.

Conclusion

The evidence is clear: consuming alcohol mixed with energy drinks is a recipe for a much more severe hangover. The combination of increased dehydration, higher alcohol consumption due to masked intoxication, and the added effects of sugar and stimulants makes the morning-after misery significantly worse. While the allure of staying alert for longer might seem appealing, the health risks and enhanced hangover symptoms far outweigh any perceived benefit. The safest and most effective way to manage your body's reaction to alcohol is to know your limits and avoid this risky combination altogether.

Frequently Asked Questions

Energy drinks contain stimulants, primarily caffeine, that temporarily mask the sedative effects of alcohol. This makes you feel more alert and less aware of your level of intoxication, even though your blood alcohol content is just as high.

Yes, it is. The masking effect of the caffeine makes you feel more sober and energetic than you actually are, which often leads to consuming more alcohol than you typically would in a single sitting, a behavior known as binge drinking.

Both alcohol and caffeine are diuretics, meaning they increase urination and cause your body to lose fluids. Combining them significantly accelerates this dehydration process, leading to more severe headaches, thirst, and fatigue.

Yes. Many energy drinks have high sugar content, which can cause a rapid spike and subsequent crash in blood sugar levels. This 'sugar crash' can worsen hangover symptoms like brain fog, fatigue, and headaches.

Short-term risks include increased heart rate, heart palpitations, insomnia, heightened anxiety, and an increased risk of alcohol poisoning due to higher consumption.

The most effective way to prevent a severe hangover is to avoid mixing alcohol and energy drinks. Instead, drink alcohol in moderation, stay hydrated by alternating with water, eat before and during drinking, and get enough rest.

Focus on rehydrating with plenty of water and electrolytes, eat a nutritious meal to stabilize your blood sugar, and get extra rest. Avoid drinking more alcohol or caffeine. Over-the-counter pain relievers like ibuprofen can help with headaches, but avoid acetaminophen.
