I Spent ₹8,700 I Didn't Mean To. Here's What My Brain Was Actually Doing.

It was 1 AM and I was somehow three carts deep on a shopping app, justifying a phone case I didn't need because it was "67% off." When I checked my account the next morning, I'd spent ₹8,700 on stuff I couldn't even fully remember adding.

The weird part? The best feeling of the whole experience wasn't getting the packages four days later. It was the waiting. The little tracking emails. The "out for delivery" notification. By the time the boxes actually arrived, I felt kind of... flat.

Which made me wonder: if I wasn't even excited when the stuff came, what was my brain chasing in the first place?


The Plot Twist About Dopamine

Here's the thing nobody told me in biology class. We all think of dopamine as the "feel good" chemical - the one that supposedly rewards you when something nice happens. Turns out that's basically backwards.

In a series of now-famous monkey studies by neuroscientist Wolfram Schultz, dopamine neurons barely fired when monkeys actually got their juice reward. They fired before - the moment a light or sound signaled the juice was coming. Dopamine isn't the molecule of "I'm happy now." It's the molecule of "something good is about to happen, GO chase it."

That tracking email I kept refreshing? The little red sale badge? The "your order has shipped" ping? Those are all anticipation cues, and they were lighting up my reward system way more than the actual products ever could. One survey found that 76% of US shoppers say they get more excited about online orders waiting in the mail than purchases they bring home from a store. Now I get why.


Why Sales Feel So Electric

It gets weirder. Dopamine doesn't just spike for anticipation, it spikes harder when the reward is uncertain. In Schultz's experiments, monkeys getting a juice reward 100% of the time produced baseline levels of dopamine. But when the reward came only half the time, dopamine release roughly doubled.

That uncertainty principle is exactly what shopping apps are engineered around. You scroll, and you don't know if the next swipe will turn up something incredible or nothing. The flash-sale timer, the limited drop, the "only 2 left" banner, they're not just marketing. They're variable rewards, the same neurological trick that makes slot machines so hard to walk away from.

The "Add to Cart" button is doing way more chemical work than I ever realized.

What Brain Scans Actually Show

Researchers at Stanford and Carnegie Mellon ran a study where they put people in fMRI scanners and let them shop, actual products, actual prices, actual money. As subjects looked at items they wanted, a region called the nucleus accumbens lit up (that's the brain's reward HQ). When the price felt too high, a different region called the insula activated, basically the same region that fires when you taste something gross.

The really wild finding: by watching the tug-of-war between those two regions, researchers could predict whether someone would buy an item, before the person consciously decided. The brain had already voted before the finger pushed the button.


Why This Hits Teens Harder

Here's the part that really made me sit up. Compulsive buying disorder shows up in about 4.9% of adults worldwide, but the rate climbs to roughly 11.5% in university students, and reviews point to adolescents and young adults as the most vulnerable group of all.

Why us? Our reward system is already running hot, teenage brains release more dopamine in response to rewards than adult brains do. Meanwhile, the prefrontal cortex (the part that says "do you actually need this?") isn't fully wired up until our mid-twenties. So we get the gas pedal of a sports car with the brakes of a bicycle, then hand ourselves an app designed by some of the smartest behavioral scientists alive.

It's not a willpower problem. It's a wiring problem.

What I Actually Changed

After reading all this, I tried three small experiments. First, a 24-hour rule: anything over ₹2000 sits in the cart for a day before I check out. About half the time, I just delete it the next morning. Second, I turned off shopping app notifications, those little dings were literally dopamine triggers I'd been training myself with. Third, when I feel that pull, I try to name it out loud: "this is anticipation, not need."

The next month, I spent around 40% less. But honestly, the bigger shift wasn't the money. It was that I stopped feeling embarrassed about impulse buys and started feeling curious about them.

The Plot Twist Ending

What got me in the end is realizing the app isn't really trying to make me happy. If it actually delivered on that, I'd stop scrolling. It's designed to keep me in anticipation, because anticipation is where the dopamine lives, and dopamine is what keeps me coming back.

So now when I feel that 1 AM urge to add something to cart, I try to ask one question. Do I actually want this thing? Or do I just want the next four days of waiting for it?

Most of the time, it turns out, I just want the waiting.

Can Sweating Protect Your Brain?

Over winter break I played the longest squash match of my life: three games, two of which I lost, all of which left me feeling like a wrung-out dishrag. So I did what I always do afterward: I dragged myself into the sauna at the club and basically melted onto the wooden bench. My grandmother was visiting that week. She'd forgotten my name twice, and honestly, it scared me. So I was already thinking about memory and aging when the guy next to me, dripping and cheerful, said his Finnish dad "saunas every single day so his brain stays sharp." I laughed it off. Then I couldn't stop thinking about it. Could sweating in a hot wooden box actually do something for your brain? The Study That Started My Spiral It turns out the Finnish-dad theory has actual research behind it. The big one is from the Kuopio Ischaemic Heart Disease study (the KIHD study), led by Jari Laukkanen and colleagues, published in Age and Ageing in 2017. They followed 2,315 middle-aged Finnish men , aged...

What One Sleepless Night Does to Your Brain

The night before my biology exam, I was awake at 3 AM with a highlighter in one hand and my phone in the other. Half of me was "studying." The other half was deep in some video about a squash player I'd never heard of, because apparently my brain decided that was the priority at 2:47 in the morning. The next day I walked into the exam like a zombie and completely blanked on a definition I had literally read at 2 AM. Gone. And here's the cruel irony I only understood later: I skipped sleep to study, but sleep is the exact thing that turns studying into memory. I basically robbed the part of me that does the saving. So what was my brain actually doing while I kept it awake? Turns out, a lot. And none of it was good. Sleep Is When Learning Actually Gets Saved Here's the part that genuinely annoyed me. When you learn something awake, it goes into your hippocampus, which is basically your brain's temporary RAM. It's quick, but it's not permanent. Sleep i...
