Water is not only vital for keeping us hydrated but also an important source of essential minerals that contribute to the proper functioning of our body. Among these, calcium, magnesium, sodium, and potassium stand out—nutrients that, in the right amounts, can improve health and well-being.
Why are minerals in water important?
Minerals present in drinking water come from the dissolution of rocks and soils through which the water flows. These compounds, known as dissolved minerals, perform key functions:
Calcium: strengthens bones and teeth, helps with blood clotting, and muscle contraction.
Magnesium: involved in over 300 enzymatic reactions, supports cardiovascular health, and helps maintain stable blood pressure.
Sodium: regulates fluid balance and nerve transmission.
Potassium: essential for muscle function and blood pressure control.
A balanced level of minerals in water can complement the diet and prevent deficiencies.
Hard water vs. soft water
When water contains high concentrations of calcium and magnesium, it is considered hard water. Although it can cause scaling in pipes and appliances, it does not pose a health risk; in fact, several studies suggest it may have cardiovascular benefits. On the other hand, soft water contains fewer minerals, which is ideal for certain industrial processes and appliances but contributes less to daily mineral intake.
How much is too much?
While minerals are beneficial, excessive amounts can have negative effects. For example, very high sodium levels in water may affect people with hypertension, and excess calcium can cause kidney problems. The World Health Organization (WHO) sets recommended ranges to ensure water safety and quality.
Water treatment and minerals
Some water purification methods like reverse osmosis remove almost all dissolved minerals, so in some cases, remineralization is recommended to maintain its nutritional value. Therefore, choosing the right water treatment system is key to balancing purity and mineral content.
Conclusion:
Water is much more than H₂O. The essential minerals it contains can improve your health if present at adequate levels. Controlling and maintaining this balance is crucial to enjoy safe, healthy water with real benefits for your body.
