Your Water Bottle
Any attempts to improve your health by carrying a reusable water bottle might just backfire if you’re not cleaning it on a daily basis.
Research published in the Annals of Civil and Environmental Engineering in 2017 revealed that the average amount of bacteria in adults’ reusable water bottles was 75,000 per milliliter. If left uncleaned, that number had the potential to reach up to two million per milliliter within a single day.
If you want to keep your bottle clean, just make sure to empty the water bottle at the end of every day and wash it with a mixture of antibacterial dish soap and hot water.
Or, if you have one, just pop it in the dishwasher. And if you want to reduce the growth of bacteria in the first place, try copper bottles, which have a natural antimicrobial effect.
