3 Coffee Habits That Hurt Your Stomach — The First One You’re Probably Doing Every Day

 For many people rushing to early shifts, a cup of coffee isn’t just a pick-me-up — it’s the “life-support system” that starts the day.

But what you may not realize is that some of your coffee-drinking habits are quietly putting stress on your stomach.

Today, let’s talk about three ways of drinking coffee that are most likely to hurt your stomach — and the first one might be something you do every single day.

1. Chugging Black Coffee on an Empty Stomach — Your Stomach Is “Crying” Silently

Many people are short on time in the morning, so they skip breakfast and drink black coffee straight away, thinking it gives the fastest boost. But this is basically like delivering a sudden attack on a stomach that hasn’t fully “woken up.”

Caffeine stimulates gastric acid secretion. When your stomach is empty and there’s no food to buffer the acid, large amounts of stomach acid come into direct contact with the stomach lining, causing discomfort. Over time, this increases stomach burden and may even lead to hidden pain or acid reflux.
Some people who are sensitive to caffeine may even experience heart palpitations or shaky hands when drinking coffee on an empty stomach.

What should you do?
It’s simple: eat something before you drink coffee.
A slice of bread, a few crackers, or a small handful of nuts can form a “buffer layer” in your stomach.
If you’re really in a hurry, at least have your coffee together with breakfast.
A gentler option is decaf coffee, or mixing your coffee with milk or oat milk to reduce direct irritation.

2. Treating Coffee Like Water — Refilling Cup After Cup All Day Long

“One cup isn’t enough, two cups keep me alive, and the third turns me into a god.”
For many office workers, this joke has become reality. From morning to night, a cup of coffee is always within reach to maintain focus. But this “coffee-for-survival strategy” actually keeps your stomach working overtime.

Caffeine needs time to metabolize. Constant intake keeps stomach acid secretion at a high level for long periods, disrupting your stomach lining’s natural repair cycle.
This is especially true with darker roasts or espresso, which often contain more acidic compounds and create longer-lasting irritation. Some people even drink coffee late in the afternoon or evening—not only harming their sleep but also forcing their stomach to “stay up late.”

The solution:
Set a “coffee cut-off time.”
Generally, reduce your intake after 3 p.m. to give your body enough time to metabolize caffeine.
Try to limit yourself to three cups a day (about 200 ml per cup).
Also keep an eye on other caffeinated drinks like tea or energy drinks so your total intake doesn’t exceed your limit.
And sometimes when you feel tired, what you actually need may just be a walk or a glass of water—not another cup of coffee.

3. Loving Scalding-Hot Coffee — Burning Your Throat and Hurting Your Stomach

“Coffee tastes best when it’s piping hot.”
It sounds reasonable, but the practice can be risky.
Drinks hotter than 65°C can irritate or slightly burn the delicate lining of the digestive tract. Long-term repeated heat irritation can affect not only the esophagus but also the stomach.

Many people brew pour-overs or instant coffee with boiling water and drink it immediately, believing the flavor is strongest this way. But the best tasting temperature for coffee is between 50–60°C, where it releases aroma without burning your mouth or digestive tract.
Letting it cool slightly makes it much gentler on your stomach.

Don’t hesitate to wait two or three minutes. Using an insulated cup helps maintain warmth while letting the temperature drop naturally to a safer level.
If you buy hot coffee outside, you can ask the barista to cool it slightly before sealing the lid, or simply let it sit with the lid open for a bit.
Treat your stomach kindly, and it’ll let you enjoy your coffee longer.

Drinking coffee should be a pleasure — don’t let habits turn it into a burden.
By adjusting a few small details, you can enjoy the clarity and aroma that coffee brings while still taking good care of your body.

What habits do you have when drinking coffee? Did any of these sound familiar?

Guangxi Coffee Explained: China’s Emerging High-Altitude Coffee Origin Beyond Yunnan

图片
 Not long ago, while scrolling through Weibo, I came across a post saying that Guangxi has started growing its own coffee . That immediately caught my attention and genuinely surprised me. Curious, I decided to dig deeper and share what I found with you. From a coffee perspective, China is actually a rather unique country. It has a complete coffee supply chain —from cultivation and roasting to distribution and consumption. China is both a coffee-producing nation and a coffee-consuming one. When people talk about Chinese coffee, Yunnan naturally comes to mind as the most well-known producing region. Over the past few years, we’ve all witnessed the remarkable transformation of Yunnan coffee. It has moved from being primarily bulk-purchased for instant coffee to embracing a mature specialty coffee path. Today, even traditionally processed Yunnan Catimor can offer a clean and pleasant cup profile, and varieties like Yunnan Geisha have also emerged, bringing greater diversity. These...

Why Water Quality Matters in Pour-Over Coffee (Alkalinity, Hardness & Flavor Explained)

图片
 The coffee we drink is, at its core, water that has dissolved the flavorful compounds inside coffee grounds. In fact, more than 98% of a cup of pour-over coffee is water. We spend so much time chasing the best origins and growing regions, the most suitable processing methods, the perfect roast profiles, and the most precise brewing techniques—yet all of these efforts ultimately rely on water to carry the coffee’s flavor. If we overlook the foundational role of water, everything else can easily fall apart. **No.1 Water Plays Two Core Roles in Coffee Brewing: Extraction and Flavor** Water is responsible for extracting soluble flavor compounds from coffee grounds, and it also makes up the body of the final beverage itself. The chemical composition of the water directly influences what ends up in your cup. **No.2 The Soluble Compounds in Water: Alkalinity and Hardness** Water contains both negatively charged ions and positively charged ions. The concentration of negatively ...

Would You Drink Coffee Made from Food Waste? The Rise of Beanless Coffee Explained

图片
 Every single second, the world consumes about 26,000 cups of coffee . On Shanghai’s Huaihai Road alone—less than two kilometers long—you can find nearly 50 cafés , each with its own style. Coffee has long since become a nationwide obsession. Enthusiasts eagerly debate bean origins, processing methods, and flavor notes, yet few stop to ask a deeper question: What hidden burden does this beloved drink place on the planet? From a food-industry carbon-emissions perspective, coffee ranks just behind beef, lamb, cheese, and chocolate . Data shows that producing a single cup of coffee consumes roughly 140 liters of water , while growing and processing one kilogram of coffee beans generates about 17 kilograms of CO₂ . Viewed through the lens of Western environmental narratives, this kind of data practically screams: ban it . How could such an “unethical” product escape scrutiny in one of the world’s environmental flag-bearers—the UK? British research has already sounded the alarm: by 20...
