Plastic bottles: why is it better not to reuse them?

With all this heat, you might want to fill up your water bottle. Nutritionists say that this is not a good thing to do. Reusing your water bottle at the beach, in a park, or in the forest is tempting, if not obvious. a habit that is good for the environment but bad for your health, according to research.

When heated, chemicals break down in water. It is a known fact that bottled water has a lot of tiny plastic pieces in it. But when it is ten times hotter, the process of molecules swapping places happens ten times faster. Chemical leaching happens when the chemicals in the plastic bottle mix with the liquid more quickly.

In a Chinese study, water bottles were kept at temperatures as high as 158 degrees Fahrenheit (74 degrees) for four weeks to show how heat affects PET water bottles, which are the most common type of disposable water bottle.

Because of this, the amount of BPA and antimony, which is a carcinogen similar to arsenic, had slowly gotten worse.

"Increasing the temperature of PET by 10°C is the same as tripling the amount of time that plastic and water are in contact with each other."

Also, the water will only get worse after the bottle has been opened.

Over time, bacteria can grow inside the bottle, which is another problem. When you open it and close it again, the germs do spread quickly. The same thing happens when the mouth touches the neck.

And in this case, you don't need to use a lot of heat because a drink can get sick even if it is left at room temperature.

The nutritionist says that the safest way to stay hydrated is to drink tap water from a stainless steel or glass gourd because "bottled water is not free of contaminants."

The expert also says not to use the water purifier or filter jug because it might have silver nanoparticles that could be harmful. In fact, these would slow down the growth and reproduction of both aquatic and land organisms and speed up their deaths.
