Is It Good to Drink the Water You Left Out Overnight?

When your body becomes deprived of water while you sleep, it is not unusual to feel thirsty upon waking up. It is reasonable to desire a sip from the glass positioned on your nightstand from the previous night. However, you may notice that the taste is somewhat altered. What could be the reason behind this?

There are a few factors that contribute to the unpleasant taste of a glass of water that has been sitting overnight. Firstly, the absence of chlorine can result in an off-putting flavor. Most public water sources are treated with chlorine to ensure sanitation and cleanliness. However, chlorine evaporates easily, leading to a change in taste. Therefore, the water you consume lacks the familiar treatment chemicals you are accustomed to.

Furthermore, the presence of carbon dioxide can also contribute to a modification in taste. As water remains stagnant over time, carbon dioxide gradually combines with the water in the glass to produce carbonic acid, thus decreasing its pH level and resulting in an unpleasant flavor.

Apart from the alteration in flavor, one might wonder: Is it acceptable to consume water that has been left in a glass overnight? Or even for two days? While it is technically safe to drink, there are a few factors to consider.

In addition to the minor changes in chemical composition, it is important to take into account the potential presence of dust and debris that may come into contact with the water. Furthermore, one must also be mindful of the possibility of bugs inadvertently falling into the glass, thus compromising the water's purity by reintroducing bacteria.

Moreover, when you consume liquid from a glass, your saliva deposits bacteria. Although these bacteria are typically harmless since they come from your own body, if left unattended for an extended period, they can become more harmful. Additionally, sharing your water with someone else is not recommended because their bacteria have the potential to make you sick.

It's important to be more cautious about leaving a partially consumed plastic water bottle in your car overnight and consuming it later. Even unopened water bottles become unsafe to drink if they have been left in the sun. Plastic bottles may contain harmful chemicals like BPA that can have adverse effects on your brain and other organs, posing potential health problems.
