First, a quick definition. Still water is simply non-carbonated water—no bubbles, no fizz, just plain H₂O. It’s the default in most restaurants, hotel rooms, and homes around the world.
Yet, in many countries—including popular destinations like Mexico, India, parts of Southeast Asia, and even rural Europe—bottled still water is the only safe bet. Why? Because local tap water often contains bacteria, parasites, or heavy metals that your unaccustomed gut hasn’t built immunity against.
The danger isn’t the water itself; it’s the invisible passengers it might be carrying. Think of it as the “quiet neighbor” who never causes trouble—until you realize they’ve been hosting a microbe party in your intestines.
