Drinking water is beneficial regardless of water quality. However, hard water is actually the much healthier option between the two. The dissolved minerals found in hard water are what make it so beneficial to drink. There are numerous advantages associated with drinking hard water over soft: hard water helps regulate blood sugar levels, aid with digestion, and improve heart function along with many other health benefits. Soft water is still safe to consume in the absence of hard water; however, naturally, the water contains fewer minerals.
