After a long sleep session, when the body uses its water reserves to stay hydrated, it is best to drink a glass of water almost when you wake up. To do this, before getting up, we just stretch our arm towards the night table and take the glass of water that, preventively, we placed the night before. However, have you noticed that that water tastes different?
According to Dr. Kellogg Schwab, director of the Johns Hopkins University Water Institute, this glass of water that stays out in the open at room temperature, goes through a process of invasion of microorganisms throughout the night. Although the treated water contains chlorine that controls the presence of these small communities, at room temperature they begin to multiply rapidly. So, regardless of whether it is clean water or a clean glass, one is drinking a mixture of germs in that colorless liquid. This is not to mention the dust from the environment that could have fallen into the glass during those hours.
However, this is not the only thing that causes the party of germs inhabiting our glass of water (or that it tastes a little less refreshing). We could say that one of the main factors is carbon dioxide: after twelve hours without having covered the water, the water begins to mix with the carbon dioxide in the air, which causes its pH to decrease and, consequently, its flavor . Although, it’s still drinkable (save for the germs swimming in our morning drink).
As for plastic water bottles left under the sun’s rays in a car, the ideal is to stay away from them. Plastic bottles contain BPA (the chemical toxic switch of the optimal functioning of the hormones), which is released with the heat of the sun. This means that, even if you wash and reuse it, the BPA remains in the structure of the bottle, causing serious health consequences.
