Alcohol consumption is a common trigger for headaches, with 95% of participants in a 2020 study reporting alcohol-induced headaches. While the exact mechanism is not fully understood, it is believed that the ethanol in alcoholic drinks acts as a vasodilator, increasing the size of blood vessels in the body and triggering migraine attacks in certain individuals. Additionally, congeners and histamine, which are found in higher concentrations in darker alcoholic beverages, may also contribute to migraine headaches. To reduce the impact of alcohol on migraines and the possibility of alcohol-induced headaches, it is recommended to drink in moderation, stay hydrated, and be mindful of individual differences in sensitivity to alcohol.

Alcoholic drinks contain histamines and congeners, which can trigger migraines
Congeners are byproducts of alcohol that have been linked to headaches. Dark-coloured alcohols like red wine, brandy, and whiskey contain more congeners than clear beverages like gin and vodka. Research has shown that 95% of participants experienced alcohol-induced headaches, with around 10% of people experiencing migraines triggered by alcohol. While the exact role of alcohol in triggering migraines is not fully known, ethanol, the main ingredient in alcohol, has been identified as a potential trigger. Ethanol is a vasodilator, which increases the size of blood vessels in the body, and this vasodilation may trigger migraine attacks in certain individuals.
Additionally, drinking alcohol when stressed is linked to a higher number of migraine headaches. It is recommended that individuals prone to migraines be careful about their alcohol consumption and consult a doctor about potential treatments.

Dark drinks like red wine, brandy, and whiskey may contain more headache-causing congeners
Alcoholic drinks contain chemicals called congeners, which are byproducts of fermentation. Congeners can cause headaches and are more commonly found in darker drinks such as red wine, brandy, and whiskey. In general, clear beverages contain fewer congeners than darker ones. For example, gin and vodka are lighter in colour and have fewer congeners than brandy, dark rum, and whiskey.
Congeners are difficult for the liver to break down, which can result in a hangover. Additionally, alcohol is a diuretic, causing dehydration, which can also lead to headaches. Drinking water before, during, and after consuming alcohol may help to prevent headaches.
While dark drinks may contain more congeners, it is important to note that any alcoholic drink can cause a headache or hangover. Individual factors, such as stress, anxiety, and genetic predispositions, can also influence the occurrence of alcohol-induced headaches.
If you are prone to migraine headaches, drinking alcohol can bring on an attack. Alcohol can cause two types of migraine headaches: immediate alcohol-induced headaches and delayed alcohol-induced headaches (DAIH). Immediate alcohol-induced headaches occur within three hours of drinking and are characterised by throbbing or pulsating pain on both sides of the head. Delayed alcohol-induced headaches may not occur until the morning after drinking and can be triggered by variable amounts of alcohol.
To determine if alcohol is the cause of your headaches, you can try keeping a diary. Each time you drink, record the type and amount of alcohol consumed, as well as any headaches that occur. Over time, you may be able to identify a pattern. If alcohol is triggering your headaches, consider reducing your consumption or abstaining altogether.

Drinking water and eating certain foods before and after drinking alcohol may reduce the chance of headaches
Drinking alcohol can lead to headaches, including migraines, cluster headaches, and tension headaches. These headaches can occur within 30 minutes to 3 hours of drinking, or even the morning after, and can last for several days. While the exact mechanism by which alcohol causes headaches is not fully understood, it is believed to be related to the presence of certain chemicals in alcoholic beverages, such as ethanol, histamine, and congeners. Additionally, alcohol can cause dehydration, which can contribute to headache development and severity.
To reduce the chance of alcohol-induced headaches, it is recommended to drink plenty of water before, during, and after alcohol consumption. Water helps to rehydrate the body and flush out the alcohol and its byproducts. Alternating alcoholic beverages with water can also help dilute the effects of alcohol and reduce the likelihood of a headache.
Eating a well-balanced meal before drinking alcohol can also lower the chances of developing a migraine. It is important to avoid drinking on an empty stomach, as this can increase the risk of a headache and other negative side effects of alcohol. Consuming food while drinking can help slow the absorption of alcohol into the bloodstream, giving the body more time to process and eliminate it.
Certain foods may also help alleviate alcohol-induced headaches. Fruits, herbs, and vegetables such as mango, thyme, ginger, and asparagus are known to contain properties that aid in headache recovery. Additionally, foods rich in long-chain omega-3 polyunsaturated fatty acids and fiber have been found to reduce the frequency and severity of migraines and headaches.
It is worth noting that individual responses to alcohol and different types of food may vary. Keeping a diary of alcohol consumption, including the type and amount consumed, as well as any headache symptoms experienced, can help identify patterns and triggers. This information can then be used to make informed decisions about alcohol consumption and headache prevention.

Migraines can begin within 30 minutes to 3 hours of drinking and can last for several days
Alcohol is a well-known trigger for migraine headaches, with around 10% of people experiencing alcohol-induced migraines. For those prone to migraines, even a small amount of alcohol can bring on an attack within 30 minutes to 3 hours of drinking. This is known as an immediate alcohol-induced headache or a "cocktail headache".
Cocktail headaches are characterised by throbbing or pulsating pain that occurs on both sides of the head and is aggravated by physical activity. They can last from a few hours to several days and are distinct from hangover headaches, which occur the morning after drinking too much. While anyone can experience a hangover headache, people with migraines are more susceptible to this type of headache as well.
The exact mechanism by which alcohol triggers migraines is not fully understood. One theory suggests that alcohol's role as a vasodilator, increasing the size of blood vessels in the body, may trigger migraine attacks in certain individuals. Another theory points to the presence of congeners, byproducts found in higher amounts in darker alcohols like red wine, brandy, and whiskey, which have been linked to headaches.
To determine if alcohol is a trigger for your migraines, it is recommended to keep a diary or journal of your alcohol consumption, including the type and amount of alcohol, and any subsequent migraine symptoms. This information can be valuable for identifying patterns and specific triggers in conjunction with a healthcare provider.
If alcohol is found to be a trigger, the best solution is to avoid it. However, for those who want to continue drinking, some strategies to reduce the impact of alcohol on migraines include drinking in moderation, staying hydrated, and consuming alcohol with a meal.

People with migraines are more susceptible to alcohol-induced headaches, but anyone can get them
Alcoholic drinks contain a chemical called ethanol, which is a vasodilator. This means it increases the size of blood vessels in the body, and this process may trigger migraine attacks in certain individuals. Dark liquors such as brandy, dark rum, and whisky contain more congeners than lighter liquors like gin and vodka. Congeners have been linked to headaches, and histamine, a common compound in alcohol, may also trigger migraines in certain people.
While anyone can experience a delayed alcohol-induced headache (DAIH), people with migraines are more susceptible. Even a small amount of alcohol can cause people with migraines to develop a delayed headache or trigger an attack within 30 minutes to three hours of drinking. A 2007 study found limited importance of alcohol intake in triggering migraines, suggesting that people with migraines may give up alcohol because they perceive it as a trigger. However, researchers are still unclear on the exact link between alcohol and migraines, and some studies have found no relationship between alcohol consumption and headaches.
If you are unsure whether alcohol is triggering your migraines, keeping a detailed diary can help identify patterns. This involves recording the type and amount of alcohol consumed, when a migraine occurred, and any other factors such as stress or anxiety. If alcohol is a confirmed trigger, avoiding it is the best solution. Drinking in moderation, having an accountability partner, and drinking water alongside alcoholic drinks can also help reduce the impact of alcohol on migraines.
To relieve a migraine once it has started, medication such as triptans may help, but it is important to consult a doctor first. Non-steroidal anti-inflammatory drugs (NSAIDs) can also provide pain relief, but they carry a risk of stomach bleeding when combined with alcohol. Drinking plenty of water and consuming fruits, herbs, and vegetables can also aid in recovery from alcohol-induced headaches.

Frequently asked questions
Alcohol is a diuretic, which means it affects the kidneys and causes the body to lose fluids more quickly than they are replaced, leading to dehydration, a common cause of headaches. Alcohol also contains ethanol, which can cause an unhealthy imbalance of chemicals in the body.
There are two main types of alcohol-induced headaches: hangover headaches, which occur around 12 hours after drinking, and cocktail headaches, which can occur within three hours of drinking. Migraines are also commonly triggered by alcohol.
Some people are more sensitive to specific ingredients in alcohol, such as histamines, sulphites, or serotonin, which may trigger a migraine or other types of headaches. Individual differences in brain receptors may also influence the brain's reaction to alcohol.
The best way to prevent alcohol-induced headaches is to avoid drinking alcohol altogether. If you do choose to drink, make sure to stay hydrated by drinking plenty of water before, during, and after consuming alcohol. Drinking in moderation, or having one drink or fewer per day for women and two drinks or fewer per day for men, may also help prevent headaches.
If you experience an alcohol-induced headache, it is important to rest and rehydrate by drinking water or sports drinks with electrolytes. Eating fruits, herbs, and vegetables, such as mango, thyme, ginger, and asparagus, may also help with recovery. It is recommended to avoid taking over-the-counter pain medications with alcohol as they can increase stress on the liver or irritate the stomach lining.
