We all know the key to a healthy mind and body is consuming lots of water, but you may need to sit down and read this before refilling your plastic water bottles.

 

According to TREADMILL reviews, drinking water from a used bottle is as bad for you as licking a toilet seat. Based on a test they conducted, they found that reusable drinking containers may be crawling with an alarming number of viable bacteria cells — more than 300,000 colony-forming units per square centimeter.

This, in layman terms means that your water bottle is extremely contaminated if you are using it without adequately washing it. “Researchers tested four types of water bottles — screw-top, slide-top, squeeze-top and straw-top — that had been used by an athlete for a week without being washed. The bottle with the most bacteria (the slide-top type) had more bacteria on it than an average toilet seat, pet bowl or kitchen sink,” reports .independent
