Why Do Some People Feel Worse After Drinking?
Share
Ever wonder why a night out leaves you wrecked? Pounding head, racing heart, restless sleep... while your friends bounce back like nothing happened?
The truth is, it’s not just about “how much” you drink. It’s about how your body processes alcohol, and more specifically, how efficiently you can clear acetaldehyde, a toxic by-product that builds up after every sip.
The Science Behind Alcohol Discomfort
When you drink, your body breaks down alcohol in two key stages:
- Alcohol (ethanol) → Acetaldehyde (a toxic, inflammatory compound)
- Acetaldehyde → Acetate (harmless and used by your body for energy)
The problem arises when step two doesn’t happen fast enough.
If your body struggles to clear acetaldehyde — because of genetics, lifestyle, or overconsumption — it lingers in your system, triggering everything from redness and nausea to poor sleep and brutal hangovers.
Why Some People Process Alcohol Differently
Everyone metabolises alcohol slightly differently. Here’s why:
- 🧬 Genetics: Around 30–40% of East Asians — and some non-Asians — carry a variant in the ALDH2 enzyme that slows acetaldehyde breakdown. This causes Alcohol Flush Reaction (Asian Glow) and amplifies side effects.
- 🥦 Lifestyle factors: Diet, hydration, sleep, stress, and certain medications affect how efficiently your liver clears acetaldehyde.
- 🍸 Tolerance myths: Drinking more won’t “train” your body to handle alcohol better. If your enzymes can’t keep up, more alcohol simply means more acetaldehyde and more damage.
Beyond Redness: Symptoms of Acetaldehyde Build-Up
While redness is the most visible sign, acetaldehyde wreaks havoc on more than just your face.
If you consistently feel worse than others after a few drinks, this toxic compound could be the reason.
| Symptom | What’s Happening in Your Body |
|---|---|
| Red face (Asian Glow) | Blood vessels dilate in response to acetaldehyde buildup. |
| Headaches & Hangovers | Toxin accumulation inflames blood vessels and disrupts fluid balance. |
| Itchy skin or eyes | Histamine and inflammatory response triggered by alcohol by-products. |
| Nausea & stomach upset | Acetaldehyde irritates the stomach lining and slows digestion. |
| Poor sleep & night sweats | Alcohol disrupts REM cycles and increases stress hormones. |
| “Hangxiety” & fatigue | Acetaldehyde affects neurotransmitters and increases oxidative stress. |
Why You Feel Worse (and Your Friends Don’t)
It’s not luck, it’s biology.
Your body’s enzymes, hydration levels, and liver efficiency determine how quickly you recover. When acetaldehyde lingers, it causes:
- Inflammation and oxidative stress in the liver
- Dehydration and disrupted hormones
- Irritation of the stomach and blood vessels
- Imbalance in serotonin and sleep regulation
That’s why even one drink can leave some people flushed, itchy, or anxious the next morning, while others feel fine.
How iBlush Helps: Beyond the Flush
At iBlush, we started by solving Alcohol Flush Reaction, but our formulas go further.
By supporting your body’s natural detox and antioxidant systems, iBlush helps reduce the entire cascade of acetaldehyde-driven discomfort.
Here’s how our science-backed hero ingredients work together:
- Glutathione – Binds and neutralises acetaldehyde to ease redness and nausea.
- N-Acetyl Cysteine (NAC) – Boosts your body’s natural glutathione production for sustained detox support.
- R-Alpha Lipoic Acid (R-ALA) – Regenerates antioxidants and reduces oxidative stress linked to hangovers and poor sleep.
💡 Think of iBlush as your all-in-one drinking support system. Designed to help your body work smarter, not harder.
The Takeaway
If you’re the friend who always feels worse after drinking — redness, hangovers, or next-day anxiety — your body’s not weak. It’s just telling you that acetaldehyde is building up faster than it can clear.
Instead of pushing through, support your system with antioxidants that help your body process alcohol more efficiently.
That’s the smarter, science-backed way to enjoy a drink comfortably, confidently, and without compromise!
Drink smarter. Feel better. The iBlush way.
