In this article: On a 35°C summer day, why do Chinese families still avoid iced drinks — and what does this have to do with how your body actually cools itself? The counterintuitive answer from a thousand years of tradition.
The Summer Paradox
Picture a humid July afternoon in Shanghai. The temperature is 36°C (97°F). The air feels like soup. Sweat drips down your back within seconds of stepping outside.
Now, what do Chinese people drink?
If you guessed iced drinks — you’d be wrong. In most Chinese homes and offices, even in the worst summer heat, you’ll be handed warm tea, hot water, or room-temperature mung bean soup. Ice is rare. Cold drinks are considered, at minimum, suspicious. Many older Chinese people wouldn’t touch an iced beverage in summer even if you paid them.
To a Westerner, this is madness. The whole point of summer is ice-cold drinks, right? Iced coffee, iced tea, ice water, frozen cocktails — cold is how you survive the heat.
So why would an entire culture do the opposite? And — here’s the real question — could they actually be onto something?
The TCM Logic: Cold Makes You Hotter (Eventually)
Traditional Chinese Medicine has a counterintuitive view of summer. Yes, the outside temperature is hot. But internally, summer is when your “Spleen and Stomach” — your digestive fire — is at its weakest.
Here’s the reasoning: in hot weather, your body pushes blood to the surface to release heat. That means less blood flow to your digestive organs. Your digestion naturally slows down. This is why appetite often drops in summer — the body is literally saying “I can’t process heavy food right now.”
Now imagine pouring ice water into an already-weakened digestive system. In TCM terms, you’re extinguishing a flame that was already low. The cold further weakens digestion, fluids don’t get processed well, and the body has to spend extra energy warming up that water to body temperature — energy that could have gone to actually cooling you down.
The TCM logic, in one sentence: cold drinks feel refreshing for ten seconds, then make your body work harder for hours.
What Chinese People Drink Instead
If not iced drinks, then what? Here’s what you’ll actually find in a Chinese kitchen during summer:
1. Mung bean soup (绿豆汤)
The #1 Chinese summer drink. Mung beans are classified as cooling in TCM — they “clear heat” without being icy cold. The soup is served warm or at room temperature, never iced. It’s the classic remedy for heat, thirst, and mild heatstroke. Every Chinese household makes batches of this in summer.
2. Warm green tea or chrysanthemum tea
Tea — served warm, even in summer. Green tea is mildly cooling. Chrysanthemum tea (菊花茶) is the classic “clear heat from the eyes and head” drink for summer. Both are sipped warm throughout the day.
3. Sour plum drink (酸梅汤)
A traditional summer drink made from smoked plums, hawthorn, licorice, and rock sugar. Tangy, slightly sweet, served chilled (not iced) — it “generates fluids and quenches thirst” in TCM terms. The classic Beijing summer cooler for centuries.
4. Warm or room-temperature water
Always. Even in summer. The default in every Chinese home.
5. Winter melon soup
A light, clear soup made with winter melon — cooling in nature, served warm. Eaten as part of summer meals to balance the heat.
Notice the pattern: everything cools you down, but nothing is ice cold. The Chinese approach to summer drinks is “cool the body from within, with foods and teas that have cooling energetic properties — not with temperature shock.”
The Scientific Side (Yes, There Is One)
Here’s where it gets interesting. There’s a counterargument you’ve probably heard: “But hot drinks cool you down faster in summer — they make you sweat, and sweat cools you.” Is that true?
Partially. A 2012 study from the University of Ottawa found that hot drinks can indeed increase total heat loss in hot conditions — by triggering sweat, which evaporates and cools. But the effect depends on conditions: it works when sweat can evaporate (dry climate, breathable clothing) and is negligible or negative in extreme humidity.
Meanwhile, the case against ice water is more modest but real:
- Very cold drinks can cause brief stomach cramps when you’re overheated
- Cold drinks constrict blood vessels in the gut, slowing digestion
- Your body does burn energy warming cold drinks to body temperature
- Cold sugary drinks (sodas, iced lattes) often lead to blood sugar crashes that leave you tireder
None of this is dangerous. But it does suggest the Chinese habit isn’t just superstition. There’s a sensible, evidence-aware logic underneath the tradition.
A Modern, Practical Middle Path
I’m not going to tell you to never drink iced coffee again. I live in the modern world too, and I love iced coffee. But here’s a sensible middle path that respects both the tradition and reality:
- Default to warm or room-temp water. Especially first thing in the morning, with meals, and on an empty stomach. This is the highest-leverage change.
- Try mung bean soup once a week. It’s genuinely refreshing and a real Chinese summer tradition. Recipe: boil a handful of mung beans in water until they split, add a little rock sugar, drink warm or at room temp.
- Sip chrysanthemum tea instead of iced tea. A handful of dried chrysanthemums in hot water, served warm. Mildly cooling, very pleasant, and better for you than sugar-laden iced tea.
- When you do have ice, make it count. Save iced drinks for genuine heat relief after exercise, not as an all-day default. Don’t drink ice water with heavy meals.
- Avoid ice on an empty stomach. Especially first thing in the morning. This is when your digestion is most sensitive.
FAQ
Aren’t cold drinks more refreshing in summer?
They feel refreshing in the moment — that cold sensation is satisfying. But the refreshment is brief, and the digestive cost can leave you feeling heavier and tireder an hour later. Warm teas and cooling foods (like mung beans) offer a longer-lasting kind of refreshment, without the post-drink slump.
What if I genuinely feel too hot and need cold?
Listen to your body. After heavy exercise, in genuine heat exhaustion, or in dry climates where sweat evaporates well, cold drinks make sense. The Chinese tradition is a default, not a rigid rule. The goal is “warm most of the time, cold when truly needed.”
Is iced coffee bad for me?
Not inherently. The caffeine and cold together can be harsh on an empty stomach, and sugary iced coffee drinks are worse. But a single iced coffee after a meal, in hot weather, is fine. The issue is more about how much and when — not the drink itself.
Why do old Chinese people seem so strict about this?
For older generations, the no-ice-in-summer habit is deeply cultural and partly about respecting the body’s rhythms. They’ve also often experienced firsthand how warm drinks prevent the digestive issues that iced drinks can cause. It’s not dogma — it’s accumulated experience.
The Bottom Line
The Chinese avoidance of cold drinks in summer isn’t about being ascetic or superstitious. It’s about a different theory of how the body cools itself — one that says: don’t shock the system with ice, support it with cooling foods and warm fluids, and let your body do what it evolved to do.
You don’t have to go cold turkey on ice. But try this for one hot week: warm water, mung bean soup, chrysanthemum tea, no ice. See if you actually feel cooler — and lighter, and less sluggish — than the week before.
You might be surprised. The tradition has stuck around for a reason.
