Reusable water bottles have become a staple accessory, with everyone from gym-goers to busy parents to students toting their favorite cup. It’s a trend that’s good for both personal health and the environment. But there’s an overlooked downside: cleanliness.
In a recent episode of the A Healthier Michigan Podcast, host Chuck Gaidica talked with Dr. Jessica Huhn, Medical Director for Provider Engagement at Blue Cross Blue Shield of Michigan, to discuss how reusable water bottles can impact health — and why it’s crucial to keep them clean.
How much water do you need?
Huhn shared that the average healthy adult should aim for about 64 ounces of water each day, though this can vary based on climate, activity level and health conditions. The best way to stay on track? Keep a water bottle handy — convenience drives compliance.
However, taking your water bottle everywhere exposes it to germs, bacteria, and even mold from countless surfaces. Many people overlook how often their bottle is touched, set down or even shared between family members. Over time, biofilm — a slimy layer that protects bacteria — can develop inside a bottle, especially if it’s not cleaned properly. This biofilm isn’t always visible, meaning germs can linger even when the bottle looks clean.
How often should you clean your water bottle?
If you use your water bottle daily, you need to clean it every day. Huhn recommends taking apart all removable pieces and washing them with warm, soapy water. Let everything air dry completely before reassembly — moisture creates an ideal environment for bacteria. For a deeper clean, run your bottle through the dishwasher once a week or soak it in a mixture of half white vinegar and half warm water, then rinse thoroughly.
Potential health risks of a dirty water bottle
Neglecting to clean your bottle can put you at risk for stomach bugs, flu and other illnesses — especially during cold and flu season or for those who are immunocompromised. Even reusable plastic bottles are safe to refill multiple times per day, as long as they’re regularly cleaned.
Aim for 64 ounces of water daily, wash all parts of your bottle every day, and don’t forget a weekly deep clean. Huhn says, keeping your bottle — and yourself — clean is just as important as staying hydrated.
