Hangovers are the unpleasant consequence of drinking too much alcohol. They are characterised by a range of physical and mental symptoms, including fatigue, headache, nausea, dizziness, anxiety, and more. While the exact mechanisms of a hangover are not yet fully understood, it is believed that multiple factors contribute to the condition, including dehydration, inflammation, the toxic byproducts of alcohol metabolism, and the effects of alcohol on the nervous system. The severity of a hangover is directly related to the amount of alcohol consumed, and there is no proven cure beyond giving the body time to recover. So, do you still have alcohol in your system when hungover? And if so, how does it affect the body's recovery?

What You'll Learn
Hangover symptoms can last up to 24 hours
Hangovers are the unpleasant consequence of drinking too much alcohol. They are caused by a combination of dehydration, toxic byproducts of alcohol metabolism, and toxic compounds found within certain alcoholic beverages. Hangover symptoms usually appear several hours after drinking, when blood alcohol content has dropped considerably and is near to zero. These symptoms can last up to 24 hours or longer.
Hangovers are characterised by a range of physical and mental symptoms. Physical symptoms include fatigue, headache, increased sensitivity to light and sound, muscle aches, and thirst. Mental symptoms include dizziness, a sense of the room spinning (vertigo), and possible cognitive and mood disturbances, such as depression, anxiety, and irritability.
The severity and duration of hangover symptoms can vary from person to person and depend on the type of alcohol consumed and the amount. Darker spirits, such as bourbon, tend to have higher levels of congeners than clear spirits, which can worsen hangover symptoms. Sulfites, which are added to wine as preservatives, can cause headaches for people with sensitivities. Drinking carbonated alcoholic drinks also tends to raise blood alcohol levels more quickly.
There is no cure for a hangover, and the only way to avoid one is to abstain from drinking or limit alcohol intake. Drinking coffee, taking a shower, or having another alcoholic drink will not cure a hangover, although these may provide temporary relief. To manage hangover symptoms, it is recommended to drink plenty of fluids, get sleep, and take over-the-counter medications like antacids or non-steroidal anti-inflammatory drugs (NSAIDs) sparingly.

Blood alcohol concentration is near zero during a hangover
Hangovers are the unpleasant consequence of drinking too much alcohol. They are characterised by a constellation of physical and mental symptoms, including fatigue, headache, increased sensitivity to light and sound, redness of the eyes, muscle aches, thirst, gastrointestinal irritation, nausea, and anxiety, among others.
Hangover symptoms typically appear several hours after drinking when the blood alcohol content has dropped considerably and is near zero. The symptoms can last for 24 hours or more, and there is no quick cure. The only way to completely avoid a hangover is to abstain from drinking alcohol or to limit alcohol intake.
While experiencing a hangover, a person's blood alcohol concentration is near zero, but it may still be above zero. The particular symptoms experienced and their intensity vary from person to person and from occasion to occasion. The more alcohol consumed, the more likely and severe the hangover. Additionally, certain types of alcoholic beverages, such as darker spirits like bourbon, which contain higher levels of congeners, can worsen hangover symptoms.
Hangovers are believed to be caused by a combination of factors, including dehydration, toxic byproducts of alcohol metabolism (such as acetaldehyde), and toxic compounds (congeners) found in alcoholic drinks. Alcohol also affects the immune system, with studies showing that people with hangovers have elevated cytokines, which are associated with nausea, headaches, fatigue, and disrupted memory formation.
Although there is no cure for a hangover, certain measures can help alleviate the symptoms. Staying hydrated, getting sleep, and taking antacids or non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin or ibuprofen can help manage discomfort. However, it is important to use these medications sparingly as they can upset the stomach.

Dehydration, toxic byproducts, and congeners cause hangovers
Hangovers are caused by dehydration, toxic byproducts, and congeners. Firstly, dehydration is a result of alcohol suppressing the release of vasopressin, a hormone that signals the kidneys to retain fluid. This leads to increased urination and fluid loss, causing dehydration, which contributes to hangover symptoms such as thirst, fatigue, and headaches.
Secondly, toxic byproducts, such as acetaldehyde, are produced during alcohol metabolism, mainly by the liver. Acetaldehyde is a short-lived, toxic compound that contributes to inflammation in the liver, pancreas, brain, gastrointestinal tract, and other organs. This inflammation is believed to be a key factor in the malaise and discomfort experienced during a hangover.
Thirdly, congeners are compounds produced during the fermentation of alcoholic beverages. They contribute to the taste, smell, and appearance of these drinks. While ethanol is the primary alcohol compound in alcoholic drinks, congeners like methanol are also present. Methanol's toxic byproducts, such as formaldehyde and formic acid, are highly toxic and can cause blindness and even death in high concentrations. The presence of congeners may explain why certain drinks, like darker spirits, tend to worsen hangover symptoms compared to drinks with lower congener levels, like vodka or gin.
Additionally, factors such as disrupted sleep, gastrointestinal irritation, inflammation, and mini-withdrawal can also contribute to or worsen hangover symptoms. It is important to note that the only way to completely avoid a hangover is to abstain from drinking alcohol or to drink in moderation. There is no scientific cure for a hangover, and the body needs time to clear the toxic byproducts, rehydrate, and restore normal functions.

Alcohol impacts the immune system and increases inflammation
Alcohol is the primary cause of a hangover, but other components of alcoholic drinks may also contribute to the symptoms. Hangover symptoms peak when the blood alcohol concentration in the body returns to about zero, and can last for 24 hours or longer. There is no cure for a hangover, and the only way to avoid one is to not drink alcohol or to keep alcohol intake to a minimum.
Alcohol also impacts the number and variety of good bacteria in the gastrointestinal (GI) tract, worsening the immune system. It disrupts communication between the microorganisms in the intestine and the intestinal immune system, and damages epithelial cells, T cells, and neutrophils in the GI system. This disruption to the composition of the gut microbiota and gut barrier function has important implications beyond the intestinal system.
Additionally, alcohol impairs mucosal immunity in the gut and lower respiratory system, increasing the risk of sepsis and pneumonia, and postoperative complications. It also increases the likelihood of HIV transmission and progression, and may affect the development and progression of certain cancers.
Chronic heavy drinking is associated with a decreased frequency of lymphocytes and an increased risk of bacterial and viral infections. Acute high-dose exposures to alcohol inhibit pro-inflammatory cytokine production, while chronic consumption of large doses inhibits phagocytosis and the production of growth factors.
Overall, alcohol has significant negative impacts on the immune system and increases inflammation throughout the body.

There is no cure for a hangover, only time and rest
A hangover is the result of drinking too much alcohol and can cause a range of unpleasant physical and mental symptoms. While there are many purported remedies for hangovers, there is no scientifically proven cure. The only way to truly recover from a hangover is to give it time and get plenty of rest.
Hangovers are caused by a combination of factors, including dehydration, the toxic byproducts of alcohol metabolism, and the presence of congeners and other compounds in alcoholic beverages. Alcohol suppresses the release of vasopressin, a hormone that signals the kidneys to retain fluid, leading to increased urination and dehydration. This can result in symptoms such as thirst, fatigue, and headache. Additionally, the metabolism of alcohol produces a toxic compound called acetaldehyde, which contributes to inflammation in the body and can cause nausea, sweating, and a fast pulse. Darker spirits and wines may contain higher levels of congeners, which can worsen hangover symptoms.
While there is no cure for a hangover, there are some strategies that can help alleviate the symptoms. Drinking fluids, including water and electrolyte beverages, can help reduce dehydration. Getting enough sleep is also important, as alcohol can disrupt sleep patterns and contribute to fatigue. Taking antacids can help settle an upset stomach, and non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can ease aches and pains. However, it is important to use these medications sparingly as they can upset the stomach. Avoiding coffee and alcoholic beverages the next morning is also recommended, as they do not speed up recovery.
It is important to note that the effects of a hangover can last for up to 24 hours or even longer. During this time, individuals may experience impaired attention, decision-making, and muscle coordination. It is advised to avoid activities that require concentration or physical dexterity, such as driving or operating machinery. The best way to prevent a hangover is to drink in moderation or avoid alcohol altogether.
Overall, while there may be ways to manage the symptoms, the only true remedy for a hangover is time and rest. The body needs time to recover from the effects of alcohol, rehydrate, and restore normal functions and activity.
