Cold Water Benefits: Why Some People Prefer to Drink Cold Water
Drinking cold water can feel refreshing, especially on a hot summer day. Many people find that chilled water helps cool them down quickly and encourages better water intake. Some studies have even found that drinking cold water may slightly boost metabolism during exercise, as the body uses energy to bring it up to core body temperature.
Cold water can help with hydration when you’re overheated or post-workout, but how your body responds may vary. While cold water helps some people feel more alert and refreshed, others may find it uncomfortable or even experience a brain freeze. The key is to stay hydrated in the way that feels best for you.
Is Drinking Cold Water Bad for You? What the Research Says
You might have heard the theory that consuming cold water when you’re hot forces your body to work harder to regulate core temperature. There’s a little truth here. When your internal body temp is high, say after running up stairs or walking in the sun, ice-cold water can cause a short-term mismatch. Your body may use extra energy to bring that cold water closer to its own 37°C range. That said, this isn’t necessarily harmful unless you’re chugging litres of it rapidly.
Another widely shared claim is that drinking cold water after a meal will cause fats to solidify in your stomach. This theory doesn’t hold up under scientific scrutiny. Your digestive system handles a wide range of food and drink temperatures, and the body’s own heat quickly neutralises any extreme cold. So while cold water may seem “bad” in these myths, it’s generally safe unless you’re extremely sensitive to cold or have a medical condition affected by it.
Cold vs Warm: Which Water Temperature Is Better for Your Health?
When it comes to the health benefits of drinking water, temperature often comes down to personal preference and context. Drinking hot water is believed by some to support digestion, especially in traditional medicine practices. It may feel more soothing during cold weather or when dealing with congestion. Similarly, room-temperature water is often recommended because it’s gentle on the system and doesn’t require the body to adjust its temperature as much.
On the other hand, cold water can help regulate body heat after exercise or in hot conditions. Both options have their place. Water can help flush toxins, aid digestion, and support every system in your body—regardless of whether it’s warm or chilled. The best temperature is the one that encourages you to drink enough water daily.
Tips for Staying Hydrated: Cold, Warm, or Room Temperature Water?
Staying hydrated is about consistency more than temperature. Whether you drink warm water, room-temperature water, or chilled water, the goal is to maintain your fluid levels throughout the day. Water helps keep energy levels steady, supports focus, and keeps your organs functioning properly.
If you’re trying to increase water intake, choose the temperature that makes you want to drink more. On a hot summer day, cold water may feel more satisfying. In winter, sipping warm or hot water might help you stay hydrated without discomfort. Stay close to your bottled water dispenser and listen to your body—thirst is your best signal. And no matter the water temperature, drinking water regularly is a habit that pays off in both comfort and health.
