We all do it. We’ll buy a plastic bottle of water from the shop and fill it back up, time and time again until it’s fallen to pieces. You think that you’re doing good for the environment, but you could actually be doing harm to your body. This is because the bottle isn’t meant to be re-filled and could contain dangerous chemicals which harbour bacteria.
Bisphenol A is a chemical used in plastic manufacturing. The use of Bisphenol A (BPA) is thought to be controversial as it allegedly interferes with sex hormones, which can affect ovulation and increase the risk of problems related to the hormones such as Polycystic Ovary Syndrome, breast cancer and endometriosis. Scientists have said that more research is required before they can determine the effect that BPA has on the human body.
Another worrying side effect of re-using your plastic water bottle is bacteria. Treadmill Reviews tested water bottles used by athletes for a week and they found that the number of bacteria reached over 900,000 colony units per square CM. To put this into perspective, that is more than an average toilet seat. They also discovered that 60% of the germs found on water bottles were likely to make people ill.
How can I avoid getting ill?
In a nutshell, you should never refill a plastic water bottle. Just use it once, and throw it away. You should invest in one that is made of glass or stainless steel. For the ultimate in clean water, invest in a filtered water cooler like one from Home2Office water coolers.
