This real reason you should never reuse plastic bottles
Apart from the environmental damage that plastic bottles are doing to the world's oceans - there's a very good reason why you should never try to reuse them for drinking.
If you tend to refill your bottle a lot, then stop right now! That's because you're increasing your chances of falling ill from a myriad of bacteria that festers every time you reuse it, making it dirtier than a toilet bowl.
So, it's not just bad for your health, but also the environment and why it's time to consider swapping them out for a re-usable bottle.
