Many of us have a habit of filling over and over the same plastic water bottles. But it seems that keeping plastic bottles longer than necessary is very harmful habit which we should immediately forget.
T.M (treadmill reviews) tested bottles in which was supplemented water for a week and found that the number of bacteria on bottles of which we drink is equal to the number of bacteria that has the toilet seat, that is, more than 900,000 colonies of bacteria per square centimeter.
Scientists reveal that 60% of bacteria are harmful to health. Yet not everything is so black.
The best solution is to replace the plastic bottles with a modern steel and stainless thermos, which you can wash it in the dishwasher. Thus, you will not worry about any bacteria, and you can refill water as many times as you want.
