Is it dangerous to reuse disposable plastic bottles?
Almost all of us are guilty of reusing disposable plastic bottles. Research has found that such refilled water bottles which were used by an athlete for a week had over 900,000 colony forming units per square cm on average which is more than what a standard toilet seat has! Besides this, dangerous chemicals can leach from these plastic bottles into the water creating health issues ranging from affecting the reproductive system to cancer.
When you reuse disposable plastic bottles, you are putting yourself at risk for bacterial infection. Bacteria and fungi are organisms which will grow in damp or partially full bottles after they have been opened. These usually are transmitted from your hands and mouth or through any dirt that touches the mouth of the bottle. As you continue to reuse these bottles, micro cracks may develop, and you may not even be aware of these. Besides, it’s tough to clean these out.
This is a chemical that is worrying and there have been concerns that this may leach out of clear polycarbonate water bottles.
Most plastic water bottles come marked with a "1" which indicates that they are manufactured out of polyethylene terephthalate, a chemical that Harvard University states may have antimony which is linked to causing cancer.
There are many who think the solution is BPA free bottles. However, it does not work this way as most manufacturers are merely replacing these with material that contains lesser known estrogenic chemicals. Too much of estrogen can cause health issues such as weight gain and menstrual problems.
Stainless steel or glass bottles
The best way to keep yourself well-hydrated and safe is to carry a stainless steel or a glass bottle. Wash it after every use and stay healthy.
