If you’ve ever wondered how to get the most out of your copper water bottle, the answer lies in how long you store the water. Experts suggest keeping water in a copper water bottle for about 6 to 8 hours to allow it to absorb just the right amount of copper ions. This simple practice, often done overnight, transforms ordinary water into a health-boosting drink that supports digestion, immunity, and even skin health. Storing it too long, however, can lead to excess copper intake, so balance is key. With the right timing, your copper water bottle becomes more than just a stylish accessory—it’s a natural wellness tool.
