Refilling your water bottle we think is a good way to save money, be eco- conscious , and help you be healthy. Nope, not exactly.
A new study has found that refillable water bottles can harbor more bacteria than your dog’s toys.
4 different water bottles were tested by athletes for 1 week. The average athlete’s water bottle contained 313,499 CFU( colony forming units of bacteria) The dogs toys tested had 2937 CFU.
The type of bottle plays a role as well. Slide top bottles had the worst rating with 933,340 CFU’s. Straw top bottles were best at 29.4 CFU. Screw top had some 160,000 CFU, while a squeeze top had 161,971 CFU.
Interestingly the slide top had the most bacteria by far , but the type of bacteria in the squeeze top was more harmful. Over 60% of the bacteria found on the water bottles could make you sick.
So what to choose…
The recommendation is the straw top bottle, with the fewest germs, most being non harmful and naturally occurring. The research also points to choosing stainless steel over plastic. Don’t let your water bottle remain half full and sit at the bottom of your gym bag or in the car for a period of time. Do wash your bottle in the dishwasher, or wash in a soapy, or bleach solution after each use.
