You’re standing in a crowded bar, shouting over a bass line that’s vibrating in your teeth, holding a lukewarm gin and tonic. Or maybe you’re on your couch, finally alone after a brutal Tuesday, twisting the cap off a craft beer. At some point, usually right before the second glass, the thought hits: why are we drinking tho? It’s a weird habit if you look at it objectively. We’re paying good money to ingest a fermented liquid that makes us dizzy, slightly dehydrated, and occasionally prone to texting people we definitely shouldn't.
Alcohol is a massive part of the human story. It’s been here since someone left a bowl of grain out in the rain ten thousand years ago and decided the bubbly result was worth a sip. But the reasons we drink today are a messy tangle of brain chemistry, inherited culture, and a desperate need to turn down the volume of the modern world.
The Brain Science of the First Sip
When you take that first drink, things happen fast. Alcohol is a "promiscuous" molecule. It doesn't just hit one receptor; it floods the system. Specifically, it hacks your GABA receptors. GABA is the brain’s primary inhibitory neurotransmitter. It’s the "chill out" chemical. By mimicking it, alcohol tells your central nervous system to slow down. That’s why that first exhale after a glass of wine feels so physical. The tension in your shoulders literally evaporates because your neurons are firing slower.
But it’s a double-edged sword.
While GABA is slowing things down, alcohol is also jacking up your dopamine levels in the ventral striatum. This is the reward center. It’s the same part of the brain that lights up when you win a bet or see a notification on your phone. Your brain marks the drink as a "win." It says, this feels good, do it again. This is the physiological core of why are we drinking tho—we are chasing a chemical shortcut to relaxation and pleasure that our ancestors used to have to work much harder for.

Dr. George Koob, the director of the National Institute on Alcohol Abuse and Alcoholism (NIAAA), often talks about the "dark side" of this cycle. He explains that as the brain tries to maintain balance, it starts to dial back its own natural feel-good chemicals to compensate for the alcohol. This leads to the "hangxiety" people feel the next day. You’ve borrowed happiness from tomorrow, and now you’re paying it back with interest.
Social Glue and the "Liquid Courage" Myth
Humans are incredibly social, but we’re also incredibly awkward. Evolutionarily, we are wired to care deeply about what our tribe thinks of us. This creates a lot of social friction. We’re often too shy to talk to the person at the end of the bar or too stressed about work to enjoy a wedding reception.
Alcohol acts as a social lubricant. It inhibits the prefrontal cortex—the part of your brain responsible for executive function and, more importantly, social inhibition. When that part of your brain goes quiet, you stop overthinking. You become "the fun version" of yourself, or at least you think you do.
Actually, it’s often more about the shared ritual than the ethanol itself. There’s a concept in sociology called "commensality"—the act of eating and drinking together. It builds trust. When everyone has a glass in their hand, there’s an unspoken agreement that "we are all relaxing now." It signals a break from the productive, serious world of work.

The Stress Trap: Why the "Relaxing Drink" Can Backfire
A lot of us use alcohol as a transition tool. It’s the bridge between the "Work Self" and the "Home Self." You close the laptop, you open the fridge. Done.
But here’s the kicker: using alcohol to manage stress is technically counterproductive. Alcohol triggers the release of cortisol, the body’s primary stress hormone. While you might feel relaxed for sixty minutes because of the GABA boost, your body is actually under more physiological stress than it was before you drank. Your heart rate is slightly higher. Your sleep quality is about to take a nosedive.
Studies from the University of Pennsylvania have shown that even moderate drinking can disrupt REM sleep. You might pass out faster, but you won't stay in the deep, restorative stages of sleep. You wake up tired, which makes you more stressed, which makes you want a drink at 6:00 PM to take the edge off. It’s a loop. It’s a very sneaky, very common loop.
Why We Are Drinking Tho: The Cultural Pressure
Look at your Instagram feed. Look at the "Mommy Wine Culture" memes or the craft beer "connoisseur" culture. Alcohol is marketed as a personality trait. It’s not just something we do; for many, it’s part of who they are. This makes it incredibly hard to opt-out.

If you go to a dinner party and ask for water, people often ask if you’re "okay" or if you’re pregnant. The social pressure to participate is intense. We drink because everyone else is drinking, and being the only sober person in a room of tipsy people is, honestly, kind of boring. You’re on a different wavelength. You see the repetitive stories and the slightly slurred words that the drinkers are totally oblivious to.
The Reality of Modern Consumption
We also have to talk about the "Zoomer" shift. Younger generations are actually drinking less than Boomers and Gen X did at the same age. They’re "sober curious." They’re looking at the data on gut health and mental clarity and deciding that the trade-off isn't worth it.
Yet, for many, the habit remains deeply ingrained. It’s the default setting for dates, celebrations, funerals, and sporting events. It is the only drug where you have to justify not taking it.
What You Can Actually Do About It
If you’re asking why are we drinking tho because you’re tired of the brain fog or the 3:00 AM wake-ups, you don't necessarily have to go "stone-cold sober" forever unless that's what you want. But nuance is key.
- Audit your "Why": Next time you reach for a drink, wait ten minutes. Ask if you’re thirsty, bored, or actually stressed. If you’re thirsty, drink a huge glass of sparkling water first. Often, the "craving" is just a habit of having something in your hand.
- The Rule of Halves: If you’re out, try the "spacer" method. One drink, one full glass of water. It sounds like something a middle school teacher would tell you, but it prevents the rapid blood-alcohol spike that leads to poor decision-making.
- Check the ABV: Modern craft beers can be 8% or 9% alcohol. That’s double a standard light beer. You might think you’ve only had "two beers," but biologically, you’ve had four. Be aware of the actual volume of ethanol you’re putting in your body.
- Try the "Dry" Challenges: Doing a Dry January or Sober October isn't just a trend. It’s a way to reset your baseline. It takes about 2 to 3 weeks for your brain’s dopamine receptors to start recalibrating after regular alcohol use. Give them that chance.
Alcohol isn't going anywhere. It’s too baked into our history and our biology. But understanding the "why" gives you the power back. Instead of it being an automatic reflex, it can become an actual choice. When you know that the "relaxation" is just a chemical trick and the "social courage" is just a silenced prefrontal cortex, the spell starts to break a little. You might still have that glass of wine, but you'll know exactly what you're signing up for.
Monitor your sleep the night after drinking. Use a wearable like an Oura ring or an Apple Watch. Seeing the data—the spiked heart rate and the lack of deep sleep—is often the "aha" moment people need to realize that the nightly ritual might be costing more than it's giving. Change starts with that awareness. Take a week off and see how your head feels on Wednesday morning. The clarity might surprise you.
