Water with Health Benefits: Why Drinking Water Hardness Matters for Your Wellbeing

Water truly is the foundation of life, as essential as the air we breathe.

But it's not simply about staying hydrated or meeting a basic physiological need.

The quality of water we choose to drink has significant implications for our health and overall wellbeing. When it comes to understanding water with health benefits, the concept of drinking water hardness becomes particularly important.

Many people don't realise that the  hardness of drinking water , which refers to its mineral content, plays a crucial role in determining the health benefit you receive from every glass you drink. 

With today's advanced water purification technologies, there's a growing trend towards systems that remove all minerals from water in pursuit of ultimate purity. While such demineralised water might be free from contaminants, it also lacks the beneficial minerals that contribute to your health.

This blog will help you understand why moderate hardness in drinking water isn't just acceptable but actually beneficial for your wellbeing.

We'll explore the balance between purification and preserving essential minerals, and examine whether the common assumption that completely demineralised water is always the healthier choice holds up to scientific scrutiny.

By understanding the importance of minerals in water and their role in maintaining your health, you can make more informed decisions about the water you drink every day.

When discussing water quality, the term "hardness" often comes up, but what does it actually mean for your daily hydration?

The hardness of drinking water is determined by the levels of dissolved minerals, specifically calcium and magnesium, that water naturally picks up as it flows through soil and rock formations

Water hardness is typically measured in milligrams per litre (mg/L) or parts per million (ppm). You might also see it expressed in grains per gallon (gpg) in some regions.

The hardness in drinking water is categorised into different levels such as soft, moderately hard, hard, and very hard, based on the concentration of calcium carbonate present.

Soft Water Characteristics

This type of water contains low concentrations of calcium and magnesium ions. Many people prefer it because it creates a good lather with soap and tends to be gentler on appliances and plumbing systems.

However, it lacks the beneficial minerals that contribute to the health benefits of harder water.

Hard Water Properties

Characterised by higher levels of calcium and magnesium, hard water can sometimes lead to limescale buildup in pipes and appliances. However, these very same minerals are what create the benefits of hard water for your health.

Understanding the distinction between soft and hard water is crucial when you're considering if hard water is safe to drink and evaluating the broader implications of water hardness on health and daily living. While soft water has its advantages in certain applications, hard water brings significant health benefits due to its mineral content.

If you've been wondering "is hard water safe to drink?" the answer is not only yes, but hard water can actually provide important health advantages. 

The minerals found in hard water, particularly calcium and magnesium are actually essential for human health.

Calcium Benefits

Most people know calcium is crucial for bone health, but it's also vital for muscle function, nerve signalling, and blood clotting. While dairy products are well-known calcium sources, the hardness of drinking water can provide a valuable supplementary source of this essential mineral.

Magnesium's Role

This mineral is involved in numerous body processes, including regulating muscle and nerve function, blood sugar levels, and blood pressure. Magnesium also contributes to bone structure development and is required for DNA and RNA synthesis, plus the production of glutathione, an important antioxidant.

Supporting Bone Health

Regular consumption of hard water provides a source of calcium that can help maintain bone density and support skeletal health as you age.

Cardiovascular Considerations

Some research suggests a correlation between adequate magnesium intake and heart health. The effects of hard water may include cardiovascular benefits due to its magnesium content.

Potential Disease Prevention

Studies have indicated that certain minerals present in hard water may help reduce the risk of some gastrointestinal and cardiovascular conditions.

Safety and Health Risks

It's a common misconception that hard water poses health risks. While mineral deposits can affect plumbing and appliances, the health risks from drinking hard water are minimal.

The minerals contributing to hardness in drinking water are actually beneficial.

The Kidney Stone Myth

Many people believe hard water contributes to kidney stones, but most kidney stones form from oxalate compounds, which aren't influenced by water hardness. The calcium in hard water can actually bind with oxalate in your digestive system, potentially reducing stone formation risk.

The evidence clearly shows that moderate hardness in drinking water, due to essential minerals like calcium and magnesium, offers several health advantages. These range from improved bone health to potential cardiovascular benefits, making the effects of hard water generally positive for most people.

In pursuing perfect purity, some water treatment systems like reverse osmosis and distillation remove nearly all minerals from water. While these processes can eliminate unwanted contaminants, they also strip away the beneficial minerals that contribute to the health benefits of water.

Reverse Osmosis and Distillation Processes

These systems are designed to remove impurities, but they also eliminate essential minerals in the process. The result is water that's almost entirely devoid of the natural mineral content that provides health benefits.

The Appeal of "Pure" Water

The primary attraction of these systems is removing potentially harmful contaminants. However, this process also means eliminating the beneficial aspects of drinking water hardness.

Missing Essential Minerals

Regular consumption of completely demineralised water may lead to deficiencies in minerals like calcium and magnesium, which are typically obtained through both water and diet.

Potential Health Implications

Long-term consumption of water devoid of essential minerals may increase the risk of mineral deficiency, potentially impacting bone health, cardiovascular function, and overall wellbeing.

Impact on Your Body's Mineral Balance

Drinking water without minerals can disturb your body's natural mineral balance, which may lead to health issues over time.

Scientific Evidence on Absorption

Research has shown that minerals in water are often more easily absorbed by the body compared to those from food sources alone. This makes mineral-rich water an important component of a balanced approach to nutrition.

Maintaining Proper Water Structure

Minerals contribute to water's natural structure, affecting its properties and how it interacts with your body. The absence of these minerals can alter water's beneficial characteristics.

While completely demineralised water may be free from contaminants, its lack of essential minerals raises questions about long-term health impacts.

The benefits of hard water, from supporting bodily functions to maintaining proper water structure, highlight why some hardness in drinking water is actually preferable to completely "pure" water.

The debate over water quality often centres on purity, but an equally important aspect is the balance of its mineral content.

The discussion around water quality often focuses on purity, but achieving the right balance of mineral content is equally important for maximising water health benefit.

Water Structure and Integrity

Minerals like calcium and magnesium help maintain water's structural integrity. This structure affects how water interacts with your body's cells and tissues, potentially enhancing the benefits of hard water.

Enhanced Hydration Properties

The presence of minerals in water can improve its hydrating capabilities. Water with health benefits from mineral content is often more effective at hydrating your body than demineralised alternatives, as these minerals aid in the absorption process.

Improving Hydration and Absorption

The right balance of minerals in water not only enhances taste but also optimises hydration and nutrient absorption in your body, maximising the water health benefit you receive.

Preventing Mineral Deficiencies

By consuming water with moderate hardness for drinking water, you can help prevent deficiencies in essential minerals, contributing to better overall health and wellbeing.

Supporting Electrolyte Balance

Minerals in water contribute to your body's electrolyte balance, which is essential for many functions including nerve signalling and muscle contraction.
