Drinking Out of Your Water Bottle Is Not Sanitary
Do you have a water bottle you refill every day and take to work or the gym? And you probably wash it once a week or so, right?
Well . . . maybe this will change your mind..
A new study tested people's water bottles after they drank out of them for a week at the gym, and they found that the amount of bacteria is off the charts.
The average bottle had 313,000 bacteria colony forming units per square centimeter. That's about 100,000 times more than your toilet seat.
And it's about six times less sanitary than drinking out of your dog's water bowl.
The researchers say it's because your water bottle is the perfect damp, hot environment for bacteria to grow. So if you are going to drink out of a reusable bottle, swap it out after a day or two.
