Beer Drunk Feels Different: Why?

Alcohol is a depressant, a stimulant, and a mood-changer, and its effects are complex and unpredictable. While chemically, all alcoholic drinks are nearly identical, the experience of drinking them can vary widely. This is due to a combination of pharmacological and social factors. The social context of drinking plays a significant role in how alcohol affects individuals, and the same drink can lead to vastly different experiences depending on the setting and company. Additionally, individual factors such as weight, sex, age, overall health, and the type and amount of food and drink consumed also influence the drunkenness experience.

Beer drunkenness depends on blood alcohol content (BAC) and varies from person to person

The effects of alcohol are felt almost immediately as it enters the bloodstream through small blood vessels in the mouth and tongue. Up to 20% of the alcohol is absorbed through the stomach and the rest is absorbed through the small intestine. The amount of food in the stomach also affects the rate of absorption. With more food in the stomach, alcohol will stick around longer, and without food, it moves to the bloodstream faster. The more alcohol in the blood at one time, the drunker you will feel.

The effects of alcohol are complex and vary from person to person. Factors such as weight, sex, age, the type of alcohol, the speed of drinking, the amount of food in the stomach, medication, and overall health can all influence the experience of drunkenness. For example, individuals with a lower body weight will feel the effects of alcohol more quickly and intensely, as they have less body tissue to absorb the alcohol. Additionally, females typically have more body fat, which holds on to alcohol longer, and they have lower body water levels to dilute the alcohol. Age also plays a role, as metabolism slows down, body fat percentage increases, and body water levels decrease with age.

The social context of drinking also influences the experience of drunkenness. Research has shown that drinking in a social setting can amplify the positive effects of alcohol. A study by Michael Sayette, director of the Alcohol and Smoking Research Laboratory at the University of Pittsburgh, found that strangers who drank together smiled more, caught each other's smiles, and spoke more. They also shared more "golden moments" when all three strangers smiled together. This social aspect of drinking can create a sense of camaraderie and enhance the overall drinking experience.

Beer's ethanol content disrupts neuron function, affecting the entire brain

Ethanol, the intoxicating agent in alcoholic beverages, has a complex impact on the brain, affecting multiple neurotransmitters and brain regions. While ethanol is a depressant, suppressing activity in certain brain areas, it can also amplify activity in specific neural pathways. This amplifying effect is particularly evident in the mesolimbic reward pathway, where ethanol increases the activity of dopamine neurons, resulting in feelings of pleasure and euphoria. This effect is most prominent at lower blood alcohol levels, typically in the early stages of drinking.

Ethanol's impact on the brain is not limited to the reward system. As a neurotoxin, it disrupts the cell membranes of neurons, which are highly sensitive and essential for proper brain function. This disruption, although mild and temporary, can affect the entire brain since neurons are the primary communicators in the brain. Ethanol inhibits glutamate, the primary excitatory neurotransmitter, and enhances the effects of GABA, an inhibitory neurotransmitter. These actions can impair rational thought, planning, memory, and anger suppression, often leading to incoherent and forgetful behaviour.

Additionally, ethanol's impact on the nervous system can cause physical symptoms such as headaches, slurred speech, and balance and coordination issues. Prolonged heavy drinking can lead to more severe consequences, including seizures, dementia, and Wernicke-Korsakoff syndrome, a brain disorder characterised by amnesia, confusion, and eyesight issues.

Beer amplifies emotions, both positive and negative

Alcohol can amplify whatever emotions you bring to the table. Sadness, happiness, excitement, anger, jealousy, and joy can all come to the surface when you've been drinking beer. This is because alcohol affects the emotion centres of the brain. It has been found that alcohol dampens the neural response in the amygdala to negative facial expressions, which may explain why drinking can serve as a social lubricant. It can also help us become less sensitive to rejection or social anxiety. However, too much alcohol can lead to aggression, bar fights, or inappropriate behaviour.

The effects of beer are also influenced by social context. Being around others in a social setting can be intoxicating in itself, and beer seems to amplify these good feelings. It also signals to others that we are letting our hair down. Research has shown that when people drink alone, they talk more about the physiological effects, such as dizziness, whereas when drinking in a social context, they talk more about feeling elated and the effects on their mood.

The effects of beer can also depend on individual factors such as weight, sex, age, and overall health. For example, females typically have more body fat, which holds on to alcohol longer, and they have less body water to dilute the alcohol. As we age, our metabolism slows down, our body fat percentage increases, and our body water decreases, all of which can affect how our body processes beer.

Beer's ethanol content stimulates the release of feel good hormones

Beer's ethanol content stimulates the release of feel-good hormones.

Beer is usually made from just four ingredients: water, grains, hops, and yeast. However, it is the alcohol content of beer (usually around 4-5%) that affects our hormones. Ethanol, a relatively small molecule, ends up present throughout the whole brain. It disrupts the cell membranes of neurons, mildly and temporarily, but neurons are complex and delicate, so this still affects their functioning. Given that all the brain's functions depend on neurons, alcohol potentially affects the entire brain all at once.

Ethanol interferes with the actions of various neurotransmitters, the chemicals neurons use to send signals to each other. It inhibits the action of glutamate, the main "excitatory" transmitter (i.e. it turns things on, increases their activity). It also amplifies the effects of GABA, the most potent "inhibitory" neurotransmitter (i.e. it lowers/prevents activity in target areas, like a light switch or volume knob).

Beer drinking can increase dopamine and endorphin release, while also elevating cortisol. Dopamine is a hormone and neurotransmitter that is released by the hypothalamus. It is often described as the pleasure hormone, and it is tied up with endorphins. Endorphins are peptide hormones that are produced in the pituitary gland. They are opioid peptides and are responsible for that "high" feeling you get. They are usually released by the body in response to pain, but they can also be released while exercising, during sex, when listening to music, or while drinking alcohol.

Light to moderate drinking can trigger the release of endorphins, reducing anxiety and relaxing us. However, heavy drinking has no effect. There is a lot of speculation that it is chasing this endorphin release that can lead to alcoholism in some people.

According to a 1997 study, even low alcohol intake can increase dopamine release. Unlike endorphins, dopamine is still released during heavy drinking, which is why it is believed to be one of the main drivers behind alcohol addiction.

Beer's effects are influenced by social context

The effects of beer are influenced by the social context in which it is consumed. The social environment can alter the experience of drinking beer, and research has shown that the places you drink, the people you drink with, and when you drink can all affect your experience of drinking beer.

For example, drinking beer in a social context, such as with friends or colleagues, can create a sense of connection and enhance social bonding. This is especially true in cultures where beer drinking is often a social activity involving rounds with friends. On the other hand, drinking alone can lead to a different experience, with people reporting more about the physiological effects of drinking, such as dizziness, rather than changes to their mood.

The social context of drinking beer can also be influenced by gender, with men and women reporting different experiences and expectations of drinking beer. Additionally, age can play a role, with younger drinkers more likely to report that drinking beer boosts their confidence and energy levels and makes them feel more attractive.

The expectations and beliefs about the effects of beer also influence the drinking experience. For instance, if someone expects beer to make them feel more social or relaxed, this can shape their actual experience of drinking beer. Furthermore, the type of beer and the presence of congeners, which are chemical impurities that affect the taste, aroma, and color of the drink, can also impact the drinking experience.

Overall, the social context in which beer is consumed plays a significant role in influencing its effects, and it is important to consider the complex interplay between the drinker's expectations, the social environment, and individual factors such as gender and age when understanding how beer affects people differently.
