Beer Headaches: Why It Happens And What To Do

Alcoholic drinks contain histamine, flavonoid phenols, tannins, tyramine, sulfites, and phenylethylamine—all of which can trigger migraine attacks. Beer, in particular, is a diuretic, which means it dehydrates drinkers throughout the night, and dehydration is a common migraine trigger. Beer also contains ethanol, which is a vasodilator that increases the size of blood vessels in the body and may trigger migraine attacks in certain individuals.

While the exact role of alcohol in triggering migraines is not fully understood, a 2018 study of almost 2,200 migraine patients found that more than a third of them reported that alcohol was a trigger. Red wine was the most common trigger among alcoholic beverages, followed by white wine, champagne, and beer.

Beer contains histamine, flavonoid phenols, tannins, tyramine, sulfites, and phenylethylamine, which can trigger migraines

Beer contains several components that can trigger migraines, including histamine, flavonoid phenols, tannins, tyramine, sulfites, and phenylethylamine. These compounds are also found in other foods that are known to trigger headaches, such as cheeses, dried fruits, processed meats, and fermented foods and drinks.

Histamine, for example, is commonly found in alcohol, particularly red wine. It can cause vascular headaches and increase inflammation throughout the body. Tyramine, another compound found in beer, is produced from the breakdown of the amino acid tyrosine and is also present in fermented and aged foods and beverages. Tannins, flavonoid phenols, and phenylethylamine are additional compounds in beer that may contribute to migraines.

The relationship between alcohol and migraines is highly individualized, and the exact role of alcohol in triggering migraines is not yet fully understood. While some people may experience migraines after consuming beer, others may not be affected. However, studies have shown that alcohol is a common trigger for migraines, with one study reporting that more than a third of migraine patients identified alcohol as a trigger.

If you want to determine whether beer triggers your migraines, you can try having a modest portion and waiting between 30 minutes to 3 hours to observe any headache symptoms. It is important to note that migraine symptoms triggered by alcohol usually occur within the first few hours or the next day after consumption.

Dehydration caused by diuretic drinks like beer can lead to migraine attacks

Alcoholic drinks like beer are diuretics, which means they cause the body to remove fluids more quickly than other liquids. This can lead to dehydration, a common cause of headaches and migraines.

Drinking alcohol can cause excessive urination and dehydration, which may result in a headache. Alcohol suppresses the release of the antidiuretic hormone vasopressin, which controls how much water the kidneys reabsorb and retain. This reduction in fluid retention leads to increased urination. Dehydration can be particularly problematic for those prone to migraines, and it is a well-known trigger for many.

The diuretic effect of beer and other alcoholic drinks is further exacerbated by their impact on the body's fluid balance. Alcohol reduces the secretion of vasopressin, a hormone that regulates urine output. This double effect on the body's fluid levels can lead to dehydration and, consequently, migraine attacks.

Additionally, the ingredients in beer, such as tyramine, histamine, or tannins, may also contribute to migraines. While researchers are still investigating the link between these ingredients and migraines, some individuals find that certain types of beer trigger their migraines more than others. For example, some people do well with low-hop beers, while others find that sulfites or histamines are the main problem.

To prevent dehydration-induced migraine attacks, it is recommended to drink alcoholic beverages in moderation, stay hydrated by drinking water, and listen to your body to recognize the signs of dehydration.

Drinking alcohol may impact serotonin nerve transmission, which has been linked to headaches

Alcohol is known to trigger headaches and migraines in some people, and while the exact role of alcohol in triggering migraines is not fully understood, several factors are thought to be at play. One of these factors is the impact of alcohol on serotonin nerve transmission in the brain.

Serotonin is a crucial brain chemical that acts as a neurotransmitter, facilitating communication between nerve cells. It plays a significant role in various brain functions, including learning, memory, perception, mood states, and responses to drugs of abuse. Serotonin levels and functions in the brain have been linked to alcohol's effects, including alcohol abuse.

Research has shown that alcoholics and experimental animals that consume large amounts of alcohol exhibit differences in brain serotonin levels compared to non-alcoholics. Both short-term and long-term alcohol exposure affect serotonin receptors, which are responsible for converting serotonin's chemical signal into functional changes in the receiving cell. These alterations in serotonin transmission can lead to abnormal brain activity, potentially resulting in psychological problems or mental illness.

Additionally, alcohol interacts with serotonergic synaptic transmission in the brain in multiple ways. A single episode of alcohol exposure can alter serotonin's synaptic functions, leading to increased serotonin release in the nervous system. This increase may be due to enhanced signal transmission at serotonergic synapses. Acute alcohol exposure has also been found to elevate serotonin levels within the brain, suggesting either increased serotonin release or slower clearance from the synapses.

Furthermore, alcohol interferes with the function of serotonin receptors, particularly the 5-HT3 receptor, which directly excites neurons. The enhanced electrical signals generated by this receptor due to acute alcohol exposure likely contribute to excessive neuron stimulation in certain brain regions. This, in turn, may lead to increased release of other neurotransmitters associated with alcohol intoxication.

While the exact mechanisms are still being investigated, the impact of alcohol on serotonin nerve transmission is believed to be a contributing factor in the development of alcohol abuse and the rewarding effects of alcohol consumption.

Congeners, which are byproducts of alcohol, have been linked to headaches

Congeners are byproducts of alcohol that have been linked to headaches. They are a component of alcoholic drinks and may trigger migraine headaches in certain people. Congeners are believed to be one of the reasons why dark-coloured alcohols like red wine, brandy, and whiskey are more likely to cause headaches.

Congeners are formed during the fermentation process, and their presence can vary depending on the type of alcohol. For example, red wine, bourbon, and whiskey have been found to have higher levels of congeners compared to other alcoholic beverages.

While the exact mechanism is not fully understood, it is believed that congeners may contribute to headaches by increasing inflammation in the body. Additionally, congeners can affect the metabolism of alcohol by stimulating certain enzymes, which may also play a role in triggering headaches.

Some studies have suggested that histamine, a compound commonly found in alcohol, may also be a contributing factor to headaches. However, the relationship between histamine and headaches is still under investigation.

Overall, congeners are believed to play a significant role in alcohol-induced headaches, and further research is needed to fully understand their impact.

People with migraine are more susceptible to hangover symptoms

Drinking alcohol can trigger migraine attacks in some people. A 2018 study of almost 2,200 migraine patients found that more than a third of them (35.6%) reported that alcohol was a trigger. While the exact role of alcohol in triggering migraines is not fully understood, it is believed that various factors are at play.

Alcohol contains ethanol, a natural diuretic that increases urine production and can lead to dehydration, a common trigger for migraines. Additionally, alcohol contains histamine and stimulates the immune system to produce more, increasing inflammation throughout the body. Congeners, which are found in higher amounts in dark-colored alcohols like red wine, brandy, and whiskey, have also been linked to headaches.

People with migraines are more susceptible to hangover symptoms than those without. A migraine hangover, or postdrome, is the final phase of a migraine attack, causing symptoms such as fatigue, body aches, and difficulty concentrating. This phase can last up to two days and may be as debilitating as the migraine itself. While there is no specific treatment for a migraine hangover, staying hydrated and maintaining a healthy diet can aid in the recovery process.

To determine if alcohol triggers migraine attacks, individuals can keep a headache diary to track their symptoms and identify patterns. Additionally, drinking in moderation, staying hydrated, and controlling other triggers such as stress and lack of sleep can help reduce the risk of migraine attacks.
