Up to 25% of bottled water is sourced from the same municipal water supply as tap water, yet many people fear that a glass of tap water left overnight becomes unsafe. The truth is, while the taste may change, the safety of stale water depends on several factors, including its source, storage, and duration of exposure.

According to the World Health Organization (WHO), unsafe drinking water contributes to over 800,000 deaths annually, often linked to the risks posed by contaminated, standing water. This highlights a crucial distinction: while clean, bottled still water is perfectly safe, the real danger lies in stagnant water and is why still water is so bad for you when it's left untreated.

Freezing water is not a reliable method for purification because bacteria often enter a dormant state rather than dying outright. Therefore, understanding the health implications of drinking thawed water is crucial for proper hydration and safety. This guide answers the question, "Is it okay to drink water that was frozen?" and provides best practices for ensuring water quality.

While pure water itself does not expire, its quality and safety can degrade over time due to storage conditions and containers. This crucial distinction answers the question: how old does water have to be to be bad? The real risk comes not from the water's age, but from how it's handled and the container it is in.

According to the World Health Organization, over 1.7 billion people globally use a drinking water source contaminated with faeces, highlighting the immense importance of water safety. For most people, a more immediate and common question is the safety of water left sitting out in an open cup overnight. While often harmless, the answer depends on several factors that can impact its quality and taste.

According to the World Health Organization, contaminated drinking water can transmit diseases such as diarrhea, cholera, and typhoid. Many people have wondered: can I drink water that's been left out overnight, or does it pose a risk? While a single night's exposure is generally low-risk, several factors influence its safety and taste.
