Alkaline water is water that has a higher pH level than regular drinking water, typically above 7. This means it is less acidic. Proponents believe that drinking alkaline water can help neutralize acid in the body, potentially leading to various health benefits, although scientific evidence is limited. Alkaline water can be naturally occurring, found in springs, or artificially created through a process called electrolysis. Some people use alkaline water ionizers to increase the pH of their tap water. It's important to note that while some claim benefits, more research is needed to fully understand its effects on health.
