Why Do Chinese People Drink Hot Water? And Other Wellness Habits
Unpacking the cultural logic behind one of China's most puzzling daily rituals —and what it reveals about the TCM view of the body.
⚡ Quick Take
- In TCM, cold is associated with stagnation; warmth promotes circulation and digestion.
- This habit intensified after 1950s public health campaigns promoted boiled water to prevent disease.
- It's not universal —southern Chinese traditionally drink more cooling herbal teas.

It is one of the first things visitors to China notice: hot water dispensers in every train station, hotel lobby, and office. Flight attendants serve it by default. Restaurants bring it unprompted. And the question “Do you want hot or cold water?” is often met with confusion —why would anyone choose cold?
To Westerners, this seems eccentric. To the Chinese, it is as natural as breathing. This guide explains the logic behind China’s hot water obsession —and why it is not as irrational as it appears.
The TCM Explanation: Cold Is the Enemy
In Traditional Chinese Medicine, temperature is not just a physical sensation. It is a physiological force.
- Cold (— han) is associated with stagnation, contraction, and slowed metabolism. In TCM theory, cold causes qi (vital energy) and blood to congeal, leading to digestive problems, menstrual pain, and reduced immune function.
- Heat (— re) is associated with circulation, expansion, and metabolic activity. Warmth promotes the smooth flow of qi and blood.
From this perspective, drinking cold water shocks the digestive system —particularly the spleen and stomach, which TCM describes as preferring warmth. Cold water must be heated to body temperature before it can be processed, expending energy that could otherwise be used for digestion and immunity.
This is why Chinese doctors routinely advise patients with digestive complaints, menstrual cramps, or chronic fatigue to avoid cold drinks and foods.
The Historical Explanation: Boiled Water Saves Lives
The TCM explanation provides the philosophical framework, but the practical habit has a more recent origin: public health campaigns in the 1950s.
Before modern sanitation, waterborne diseases —cholera, dysentery, typhoid —were major killers in China. In 1952, the Communist government launched the Patriotic Health Campaign, which included the mass promotion of boiled drinking water. The slogan was simple: “Drink boiled water, prevent disease.”
Boiling water was an effective, low-cost solution for a country without widespread water treatment infrastructure. Public hot water dispensers were installed in schools, factories, and train stations. The habit became institutionalized —and then cultural.
Within a generation, drinking hot water became so normalized that cold water began to seem foreign, even unhealthy.
The Geographic Divide
Hot water culture is not uniform across China. Regional climate influences beverage preferences:
- Northern China: Cold, dry winters make hot water essential. Indoor heating was historically inadequate, and hot drinks provided warmth.
- Southern China: Hot, humid summers historically led to different solutions. In Guangdong and Hong Kong, cooling herbal teas (凉茶, liangcha) are consumed year-round to counteract heat and dampness.
- Tibet and high-altitude regions: Butter tea (酥油茶 / su you cha) —hot tea mixed with yak butter and salt —provides calories and warmth in extreme cold.
The nationalization of hot water culture was partly a political project: creating a unified “Chinese” health practice across diverse climates and traditions.
What the Science Says
Western medicine does not recognize TCM’s “cold stagnation” theory. But the empirical effects of hot water drinking have some scientific support:
| Claim | Evidence |
|---|---|
| Hot water aids digestion | Warm liquids may help dissolve fats and speed gastric emptying (limited evidence) |
| Hot water relieves congestion | Steam from hot beverages can temporarily clear nasal passages |
| Hot water is safer | Boiling kills pathogens —true, but irrelevant in areas with treated tap water |
| Cold water causes illness | No direct evidence in peer-reviewed literature |
The consensus: drinking hot water is not inherently healthier than drinking cold water in sanitary conditions. But it is not harmful either. And the cultural habit has genuine public health benefits in contexts where water safety is uncertain.
Modern Tensions
Hot water culture is now encountering pushback from younger Chinese, particularly those exposed to Western habits through travel and media:
- Bubble tea (奶茶, naicha) —usually served cold or iced —has become a multi-billion dollar industry
- Cold brew coffee is gaining popularity in major cities
- Gym culture promotes ice water for workout recovery
But the default remains hot. Order water at any Chinese restaurant, and you will receive a glass of hot water. Ask for cold, and you may receive a look of mild concern —as if you have just announced you plan to eat raw meat.
Practical Tips for Visitors
If you visit China:
- Carry a thermos —Refill at hot water stations in airports and train stations
- Do not drink tap water —Even locals boil it first
- “Warm” (温水, wenshui) vs. “Hot” (热水, reshui) —Hotels may offer both; warm is drinkable immediately, hot requires waiting
- Herbal tea —If you tire of plain water, ask for chrysanthemum (菊花) or goji berry (枸杞) tea —both are widely available
