The Right Temperature for Drinking Water
Generally speaking, a water temperature of 30–40°C, which is close to body temperature, is comfortable for drinking. When consuming water, try to avoid drinking it too hot or too cold. Additionally, here are some recommendations regarding the ideal drinking water temperature and the reasons behind them:
1. Avoid drinking excessively hot beverages. The World Health Organization (WHO) has classified beverages above 65°C as "Group 2A probable human carcinogens," as they may increase the risk of esophageal cancer.
2. Use the right temperature for brewing tea. When making tea, especially green tea, the water temperature should be kept between 70–80°C to preserve the tea leaves' bioactive compounds. Always allow the tea to cool to a suitable temperature before drinking.
3. Drink mineral water at an appropriate temperature. It is best to consume mineral water warm or slightly chilled to maintain its taste and nutritional value.
4. Ensure safe water temperature for infant formula. Since tap water may contain microbial risks, all water used for preparing infant formula should be boiled and then cooled to an appropriate temperature before use.
5. Avoid excessive or rapid consumption of ice water. Many young people enjoy drinking ice water, which is fine in moderation. However, excessive or frequent intake can lead to vasoconstriction, gastrointestinal spasms, reduced digestive enzyme activity, and impaired digestion. In severe cases, it may even cause diarrhea. Additionally, for women, drinking excessive ice water may contribute to menstrual pain and negatively affect reproductive health.
In hot weather or after intense exercise, consuming ice-cold purified water (which lacks electrolytes) can increase the risk of cardiovascular issues or, in extreme cases, even sudden death. Therefore, remember this important advice: drink water in moderation, even when you are very thirsty, to stay safe.
For many Chinese people who prefer drinking hot water, the temperature of water is not only a health consideration but also an emotional connection. "Drink more hot water" is a phrase frequently heard from friends and elders as a gesture of care. Whether experiencing a headache, stomachache, or toothache, people often advise drinking hot water. At one point, this phrase even became a cultural catchphrase, symbolizing warmth and concern from others.
What's the Ideal Drinking Water Temperature? Health Benefits Explained
1. The Science Behind Water Temperature
Body absorption rates: Cold water (4–10°C) absorbs faster during exercise.
Digestive impact: Warm water (35–40°C) relaxes gastric muscles, aiding digestion.
2. Best Temperatures for Different Needs
| Scenario | Recommended Temp | Why It Works |
|---|---|---|
| Morning hydration | Warm (35–40°C) | Kickstarts metabolism, detox |
| Post-workout | Cool (10–15°C) | Rapid rehydration, cools body |
| Mealtime | Room temp (~25°C) | Avoids diluting digestive enzymes |
3. Myths vs. Facts
❌ Myth: "Ice water burns calories."
✅ Fact: Burning is negligible (<8 calories per glass).
❌ Myth: "Cold water causes fat buildup."
✅ Fact: No evidence-but may tighten oils in greasy meals.
4. When Temperature Matters Most
Chronic conditions:
IBS sufferers: Warm water reduces cramping.
Sore throat: Lukewarm water soothes irritation.
Seasonal tips:
Summer: Cool water (10–15°C) prevents overheating.
Winter: Warm water maintains core temperature.
5. How to Control Water Temperature at Home
Use adjustable temp faucets (like Hot and Cold Water Tap).
Insulated bottles to maintain preferred temps on-the-go.
