Voice 1: It is well known that adequate hydration is essential for your body to function properly. Water doesn't just quench your thirst: it regulates temperature, eliminates toxins, keeps joints flexible and stimulates important functions such as nutrient supply. But you may not know that your trusty water bottle could be full of germs.
Voice 2: A 2022 study found that the average reusable water bottle harbors more bacteria than a toilet seat. The researchers measured the amount of live bacteria in these vials. On average, the bottles contained 20.8 million CFU, which is the equivalent of colony-forming bacterial units, 40,000 times more than in a toilet seat.
Voice 1: The type of bottle also made a difference. Screw top bottles contained the lowest amount of bacteria at just 3 million CFU, while spout or screw top bottles contained up to 30 million CFU, a similar number to that found in a faucet.
Voice 2: The study also found that of the 1,000 Americans surveyed, a quarter washed their water bottles several times a week, and just over 10% only cleaned them a few times a month. These alarming statistics highlight how important it is to properly clean and care for these everyday items.
Voice 1: Dr. Jay Vornhagen, an assistant professor at Indiana University School of Medicine, said water bottles can make you sick if you don't clean them properly. Their research found several bacteria on water bottles, including potentially harmful bacteria such as staph and coliform bacteria.
Voice 2: To prevent your water bottle from becoming a breeding ground for germs, experts recommend rinsing it daily with soap and water or sometimes white vinegar and then drying it well. Once a week, clean it thoroughly by taking it apart and scrubbing it with a bottle brush until you reach the sensitive areas. Your water bottle goes with you everywhere. You can protect your health with a regular cleaning routine.
