Many folks in the West are used to drinking ice-cold water throughout the day, especially with meals or after a workout. (We get it, there’s nothing quite like that first sip of a crisp, cold drink). But across much of Asia, that habit looks very different. In many households, restaurants, and even hospitals, warm or room-temperature water is the norm. In fact, many people will avoid cold water even in the summer months.
This difference isn’t just cultural—it’s rooted in long-standing wellness beliefs that continue to shape daily habits today.
A Different Way of Thinking About the Body
In traditional East Asian practices, particularly those influenced by Traditional Chinese Medicine (TCM), the body is viewed as a system that functions best when it maintains internal balance. One commonly referenced idea is that digestion works more efficiently when the body stays “warm.” On the flip side, when the body is exposed to excessive coldness, or “yin,” this balance can be disrupted, potentially slowing digestive processes and causing discomfort.
Because of this, cold drinks—especially ice water—are often avoided during meals. Instead, warm or room-temperature liquids are thought to support the body’s natural functions and help maintain a more comfortable internal state.
Why Warm Water Is Preferred
Instead of cold drinks, many people in China, Japan, and Korea prefer warm or hot water throughout the day. This is especially common in the morning or after eating. Warm water is associated with:
- Supporting digestion
- Promoting circulation
- Helping the body feel more balanced
In some cultures, it’s also common to drink warm water first thing in the morning as a way to gently “wake up” the system and keep your body running smoothly.
Everyday Habits That Reflect This Belief
This preference shows up in daily life in simple ways. At restaurants in China, hot water or tea is typically served instead of iced water. In Japan, even convenience stores sell a wide range of warm bottled drinks during colder months.
It’s also common for people to avoid cold beverages when they’re feeling unwell. Instead, warm soups, teas, or plain hot water are often the go-to choices.
A Growing Curiosity Abroad
In recent years, this habit has started to gain attention outside of Asia. As more people explore global wellness practices, the idea of avoiding cold drinks, especially for digestion, has become a topic of curiosity.
Some have started experimenting with switching from iced drinks to room-temperature or warm water, particularly in the morning or during meals.
The Takeaway
Drinking cold water isn’t considered harmful in most modern medical contexts, but the preference for warm water reflects a different approach to everyday wellness—one that emphasizes balance, comfort, and long-term habits.
For those curious about incorporating small changes, simply trying room-temperature water instead of ice-cold drinks can be an easy place to start.
