Still water is non-carbonated water. It can come from various sources such as ordinary tap water, spring water, natural mineral water, and most bottled water found in large containers. It is important to note that while still water comes from nature, it is only safe to drink from a trusted, tested, and filtered water source.

The term "still water" can also refer to a part of a stream where no current is visible.

The benefits of drinking still water include hydration, carrying nutrients to all parts of the body, and providing valuable health benefits. It is the most beneficial fluid for staying hydrated and is crucial to maintaining several functions of our bodies. Other fluids, such as soft drinks and sports drinks, contain sugar and sodium that can cause a reverse effect and actually dehydrate our cells.

In contrast, sparkling water contains dissolved carbon dioxide while still water does not. Carbonation gives sparkling water its signature "fizzy" taste. While carbonated water is just as hydrating as regular water, tap water has the added benefit of fluoride, which helps prevent tooth decay. Carbonated water still has the potential to be erosive, so it is recommended to think of it as a once-a-day treat rather than your main source of water.

At the end of the day, water is water and is incredibly important to be consumed on a daily basis. While both sparkling and still waters can offer great benefits individually, its important to note that depending on your lifestyle, one may serve as a better option than the other.
