Beer Hangovers: Type And Intake Matter

Drinking alcohol can lead to a hangover, a set of symptoms that occur as a consequence of drinking too much. Typical symptoms include fatigue, weakness, thirst, headache, muscle aches, nausea, stomach pain, vertigo, sensitivity to light and sound, anxiety, irritability, sweating, and increased blood pressure. While the amount of alcohol consumed is the main factor in determining the severity of a hangover, the type of alcohol may also play a role. Congeners, compounds produced during fermentation that contribute to the taste and smell of alcoholic beverages, are thought to influence hangover severity. Darker spirits, such as bourbon, tend to have higher levels of congeners and can worsen hangover symptoms. Clear alcoholic drinks, such as light beer, gin, and white wine, have lower levels of congeners and may result in less severe hangovers. However, the best way to prevent a hangover is to drink in moderation or avoid alcohol altogether.

Alcohol is the main cause of a hangover

The severity of a hangover depends on how much alcohol is consumed and for how long. However, other factors such as health, genetics, and personal physiology also play a role. Some people experience a hangover after just one drink, while others who drink heavily may not experience any symptoms at all. Ultimately, the more alcohol a person drinks, the more likely and severe the hangover will be.

Alcohol affects the body in several ways that contribute to hangover symptoms:

• Dehydration: Alcohol is a diuretic, causing increased urination and fluid loss. This leads to dehydration, which results in thirst, fatigue, and headaches.
• Electrolyte imbalances: Alcohol increases urination, disrupting the balance of electrolytes that the body needs to function optimally.
• Gastrointestinal irritation: Alcohol irritates the lining of the stomach and intestines, slowing digestion and leading to nausea and stomach discomfort.
• Inflammation: Alcohol increases inflammation throughout the body, contributing to the general unwell feeling associated with hangovers.
• Low blood sugar: This effect is more common in people with alcohol use disorder. Alcohol metabolism produces lactic acid, which reduces blood sugar production, resulting in fatigue, sweating, hunger, and shakiness.
• Disrupted sleep: While alcohol promotes sleep, hangover symptoms interfere with sleep quality, leading to fatigue.
• Alcohol withdrawal: Drinking alcohol initially produces feelings of calmness and relaxation. However, when the effects wear off, individuals may experience increased restlessness, anxiety, and irritability.
• Alcohol metabolites: When the body breaks down alcohol, it produces acetaldehyde, a toxic byproduct that can cause a fast pulse, sweating, and nausea.

While alcohol is the primary cause of hangovers, other compounds in alcoholic beverages, called congeners, may also contribute to hangover severity. Congeners are produced during the fermentation and distillation processes and influence the flavour, aroma, and appearance of the drink. Darker-coloured drinks, such as bourbon, whiskey, and red wine, tend to have higher levels of congeners and are associated with more severe hangovers. Lighter-coloured drinks, such as vodka, gin, light beer, and white wine, have lower levels of congeners and may result in less severe hangovers.

Additionally, sulfites, which are preservatives added to wine, can cause headaches in sensitive individuals. Therefore, while alcohol is the main culprit of hangovers, the type of alcoholic beverage consumed may influence the severity of symptoms due to the presence of congeners and sulfites.

Congeners in alcohol may worsen hangovers

Congeners are compounds produced during the fermentation process of alcoholic beverages. They are responsible for the taste and aroma of distilled alcoholic drinks and contribute to the taste of non-distilled drinks. While ethanol is the main source of hangovers, congeners may also play a role in worsening hangover symptoms due to their potential toxicity.

Dark liquors, such as cognac, brandy, red wine, dark whiskey, and bourbon, typically have high levels of congeners. These darker liquors may lead to more severe hangovers compared to lighter or clear alcoholic beverages. Tequila is an exception, as it also contains high levels of congeners. On the other hand, clear drinks like vodka, white wine, gin, light rum, sake, and light beers have low levels of congeners and are less likely to result in severe hangovers.

One notable congener, methanol, breaks down into formaldehyde and formic acid. Those who produce larger amounts of methanol may experience worse hangover symptoms. The highest quantities of methanol are found in dark liquors. Another congener, acetaldehyde, is a toxic substance and a byproduct of ethanol breakdown, which can contribute to inflammation in the body.

While the amount and type of congeners present depend on the carbohydrate used for fermentation, such as grains for beer, grapes for wine, or potatoes for vodka, the distillation process also influences the number of congeners remaining in the final beverage.

It is important to note that the total amount of ethanol consumed is still the primary factor in determining hangover severity. However, choosing alcoholic beverages with fewer congeners, such as beer, vodka, or wine, may help reduce hangover symptoms compared to drinks with higher congeners like brandy, whiskey, or rum.

Sulfites in wine may cause headaches

The type of alcohol you drink can affect the severity of a hangover. While alcohol is the main culprit, other components of alcoholic drinks might contribute to or worsen hangover symptoms. Congeners, for example, are compounds produced during fermentation that contribute to the taste and smell of alcoholic beverages. Darker spirits, such as bourbon, tend to have higher levels of congeners than clear spirits, which can lead to more severe hangovers for some people.

Now, onto the question of whether sulfites in wine may cause headaches. Sulfites are compounds added to wine as preservatives to prevent spoilage and maintain colour. While some people believe that sulfites are the cause of their wine-induced headaches, the link between the two is not clear-cut. Research on this topic is inconclusive, and scientists have not found a direct correlation between sulfites and wine headaches. However, it is important to note that a small percentage of the population (about 1%) is sensitive or allergic to sulfites. For these individuals, exposure to sulfites can trigger allergic reactions such as hives and difficulty breathing rather than headaches.

So, what could be the cause of wine headaches? Several factors come into play. Histamine, a compound found in grape skins, is one possible culprit. Red wine contains higher levels of histamine than white wine because it is made from the whole grape, including the skin. Some people lack the enzyme that breaks down histamine in the small intestine, and alcohol can further inhibit this enzyme. As a result, drinking red wine may lead to increased histamine levels in the blood, which can cause blood vessels to dilate and trigger a headache.

Another potential contributor to wine headaches is tannins, which are plant chemicals found in grape skins that impart flavour to red wines and contain antioxidants. Tannins can stimulate the release of certain neurotransmitters associated with pain. Additionally, they can block the detoxification of other components in wine, such as phenols, which have been linked to migraine episodes.

Wines with additives, including sugar and sweeteners, may also be a factor in wine headaches. However, it can be challenging to pinpoint the specific chemical responsible for the side effects. Dehydration is another factor that can contribute to headaches, as alcohol has a diuretic effect, leading to fluid loss and decreased blood volume.

To conclude, while sulfites in wine may not be the primary cause of wine headaches, various factors, including histamine, tannins, additives, and dehydration, can play a role in triggering headaches for some individuals.

Drinking disrupts sleep, causing fatigue

Drinking alcohol can negatively impact sleep quality, leading to fatigue and tiredness. While alcohol is known to be a sedative that can initially promote sleep, it disrupts sleep patterns, causing grogginess and fatigue the next day. This is because alcohol interferes with brain activity during sleep, and the hangover symptoms that follow excessive drinking can also interfere with sleep.

Alcohol affects the hormones that regulate our biological clocks, and the resulting disruption can make a person feel like they have jet lag. Sleep is also impacted by the withdrawal symptoms that occur when the positive effects of alcohol wear off. As the nervous system readjusts, individuals may experience restlessness, anxiety, and irritability. These symptoms can make it difficult to fall asleep or result in fragmented sleep, contributing to fatigue.

Additionally, alcohol can trigger migraines, and some people may mistake an alcohol-induced migraine for a hangover. The severity of a hangover is often associated with the level of intoxication, and the resulting disruption to sleep can further intensify the symptoms.

To mitigate the impact of drinking on sleep, it is recommended to drink in moderation, stay hydrated, and prioritize getting sufficient rest after consuming alcohol. These measures can help reduce the negative effects of alcohol on sleep and lessen the feeling of fatigue.

Drinking causes dehydration, leading to hangover symptoms

Drinking beer or any alcoholic beverage can cause dehydration, which is a common symptom of a hangover. Alcohol is a diuretic, which means it increases the production of urine. Alcohol suppresses the release of the hormone vasopressin, which is responsible for sending signals to the kidneys to retain fluid. As a result, alcohol consumption leads to increased urination and the loss of fluids, causing dehydration.

Dehydration caused by alcohol consumption can result in symptoms such as thirst, fatigue, and headaches, which are commonly associated with hangovers. The dehydration effect is more pronounced when consuming alcoholic drinks with higher congeners, such as dark spirits like bourbon, brandy, whiskey, and dark beers. These drinks tend to have higher levels of congeners, which contribute to dehydration and worsen hangover symptoms.

To counteract the dehydrating effects of alcohol, it is important to drink water or other fluids and alternate between alcoholic beverages and water. This helps maintain hydration levels and reduces the severity of hangover symptoms.

In addition to dehydration, alcohol can also disrupt sleep patterns, irritate the gastrointestinal tract, increase inflammation in the body, and affect hormone production. These factors collectively contribute to the hangover symptoms experienced the day after drinking.

While the type of beer or alcoholic beverage may have some influence on hangover symptoms, the amount of alcohol consumed is a more significant factor. Drinking in moderation and staying hydrated are key strategies to prevent and mitigate hangover symptoms.
