More and more people are moving to more environmentally friendly water bottles to reduce waste and save nature. But do you know that repeated use of one bottle can carry health risks? The bottles quickly become the ideal hatchery for bacteria.

One use bottles are environmentally unsustainable, and therefore more and more people are moving to ecological variants such as repeated use bottles. It is certainly a step in the right direction to protect the environment, but American scientists have found that these bottles can be dangerous to your health if you do not pay enough attention to their washing.

Without regular cleaning, they easily become an ideal environment for the multiplication of dangerous bacteria. Their source is not only a human mouth that comes into contact with the bottle throat, but also the environment in which the bottle is located.

More bacteria than on the toilet board

According to laboratory tests, scientists have found that repeatedly usable water bottles are much dirty than most of you could think. They have turned out to be even dirty than a kitchen sink or mouse at a computer that you touch every day. But what is really alarming is the fact that reusable bottles contain much more bacteria than the toilet board. In fact, there are several thousand more bacteria than you would imagine.

If these healthy bacteria in the bottle overgrown, they can cause various health problems, especially digestive problems. Some of these bacteria are resistant to commonly available antibiotics, which is an even greater problem. It is therefore crucial to regularly clean the reusable bottles and pay attention to the necessary attention to minimize the risk they can pose for our health.

How to clean bottles

It is therefore very important to remember regular cleaning of reusable bottles to minimize the risk of the multiplication of these dangerous bacteria as much as possible. You should wash the bottle with warm water and soap at least once a day. If you are used to carrying other drinks other than water, such as tea, fruit syrup or coffee, it is best to wash it thoroughly with detergent after each use.

Once a week, you should focus on a thorough disinfection, because water and soap are often not enough to destroy all bacteria that will settle in the bottle within a few days. The disinfection used should be harmless and, if possible, without strong odor, so that your favorite drink does not sniff with chemicals.

So whether you prefer drinks in a one -time packaging or seek ecological solutions, don’t forget your health. Places that seem safe to us, such as an ordinary bottle, can actually be hidden threats and may pose a hygienic risk to your health.
