Stop Treating Coffee as a “Life-Support Elixir” — 8 Types of People Who Should Cut Back

 For many office workers, surviving the day often means running on caffeine. A cup of coffee in the morning, another after lunch, and maybe one more to power through overtime. Coffee truly helps you stay alert—but for some people, overdoing it could quietly harm your health.

Let’s start with a real case:
A 32-year-old office worker drank at least five cups of coffee every day to stay awake for overtime. One evening, she suddenly felt her heart racing, her hands shaking, and cold sweat pouring down. She was rushed to the hospital, where doctors diagnosed her with caffeine-induced arrhythmia. The doctor warned her seriously: “If you keep drinking coffee like this, your heart won’t be able to handle it.”

Coffee can be wonderful, but it’s not for everyone. Here are eight groups of people who need to watch their caffeine intake carefully.

1. People with Heart Problems

Caffeine stimulates the sympathetic nervous system, which can cause faster heartbeats and higher blood pressure. If you already experience heart palpitations or irregular rhythms, coffee can make things worse. Those with heart disease should be extra cautious—too much caffeine can even trigger serious arrhythmias.

2. People with Poor Sleep Quality

If you struggle with insomnia or light sleep, it’s best to avoid coffee after 3 p.m. Caffeine can linger in your body for hours, and sensitive individuals may still feel its effects well into the night. Relying on coffee to stay awake can easily turn into a vicious cycle: sleep poorly → drink coffee → sleep even worse.

3. People with Excess Stomach Acid

Caffeine increases stomach acid production, which can worsen symptoms for those who already suffer from acid reflux or gastritis. Drinking coffee on an empty stomach can irritate the stomach lining even more.

4. People with Osteoporosis

Caffeine slightly reduces calcium absorption and increases calcium loss through urine. Older adults—especially women showing signs of bone density loss—should limit their coffee intake and make sure to get enough calcium from food or supplements.

5. Pregnant or Breastfeeding Women

Women during pregnancy and lactation need to be especially careful. Caffeine can cross the placental barrier and affect the fetus, and it can also pass into breast milk. Always consult your doctor before consuming coffee during these periods.

6. People with Anxiety Disorders

Caffeine may heighten anxiety, causing heart palpitations, trembling, or restlessness. If you’re naturally prone to anxiety, caffeine’s stimulating effects can make emotional symptoms even worse.

7. People Taking Medication

Caffeine can interact with certain drugs—such as some antibiotics and blood pressure medications—either weakening their effectiveness or increasing side effects. If you’re on medication, ask your doctor whether it’s safe to drink coffee.

8. People Sensitive to Caffeine

Some people are naturally more sensitive to caffeine. Even a small cup can cause heart palpitations, shaky hands, or insomnia. If that’s you, consider switching to decaffeinated coffee or other alternatives.

Coffee itself isn’t bad—moderate consumption can actually benefit your health. The key is moderation and personal suitability.

So how can you tell if you’re overdoing caffeine? If you often experience any of the following, it might be time to cut back:

  • Heart palpitations or trembling hands

  • Insomnia or vivid dreams

  • Headaches or dizziness

  • Stomach discomfort

  • Anxiety or irritability

Your health matters more than a temporary energy boost. Try gentler ways to refresh yourself:

  • Take a short 10-minute break

  • Stand up, stretch, or walk around

  • Stay hydrated

  • Practice deep breathing to relax

Finding your own pace is the secret to sustainable energy.

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...
