what is alkaline water and how does it work

In recent years, alkaline water has become a popular beverage shrouded in claims of improved health and well-being. But what exactly is alkaline water, and is the science behind it as convincing as the marketing hype? This comprehensive guide dives into the fascinating world of alkaline water, exploring its properties, potential benefits, and the science that underpins it all.

pH: The Building Block of Alkaline Water

pH: The Building Block of Alkaline Water


Imagine a scale from 0 to 14, where 7 represents a perfect balance. This scale, known as the pH scale, measures how acidic or alkaline a substance is. Think of lemon juice with its sharp tang – that's acidic and falls on the lower end of the scale. 

On the other hand, baking soda with its cleaning power leans towards the alkaline side, occupying the higher numbers. Regular drinking water typically rests comfortably at a neutral pH of 7.

Alkaline water, however, takes a slight detour from neutrality, boasting a pH level that's slightly higher, usually ranging from 8 or 9. This altered pH state is achieved through various methods, like electrolysis which splits water molecules, or by adding minerals like calcium and magnesium.

Does Alkaline Water Really Work? The Body's pH Balancing Act

Body's pH Balancing Act


Proponents of alkaline water often tout its ability to neutralise excess acid in the body, leading to a domino effect of positive health outcomes. The theory goes something like this: our modern diet, laden with processed foods and sugary drinks, throws our body's pH balance off kilter, creating an acidic environment. 

Alkaline water, with its higher pH, swoops in like a knight in shining armor, restoring balance and promoting overall health.

However, the human body is a marvel of self-regulation. We possess a complex system, primarily involving the kidneys and lungs, that works tirelessly to maintain a healthy pH level in the blood, ideally between 7.35 and 7.45. 

Regardless of what we eat or drink, this intricate system efficiently removes excess acid or base to keep this narrow range in check. So, while alkaline water might alter the pH of your urine, it's unlikely to have a significant impact on your blood's tightly controlled pH.

A Look at the Research: Potential Perks of Alkaline Water

Potential Perks of Alkaline Water


While the claims of alkaline water being a health panacea lack strong scientific consensus, some studies suggest potential benefits in specific areas:

Enhanced Hydration: Research suggests that alkaline water might improve hydration, particularly after exercise. This could be due to its lower blood viscosity, allowing fluids to flow more easily throughout the body.

Acid Reflux Relief: Studies indicate that alkaline water may offer temporary relief from the burning discomfort of acid reflux by neutralizing stomach acid.

Bone Health: Limited research hints that alkaline water could potentially play a role in bone health, although more robust studies are needed to solidify this claim.

It's important to remember that these studies are ongoing, and more research is needed to confirm any definitive health benefits associated with alkaline water consumption.

Important Considerations for Alkaline Water Consumers

While generally safe for most healthy individuals, there are some factors to keep in mind when incorporating alkaline water into your routine:

Mineral Makeup: Commercially available alkaline water can vary greatly in its mineral content. Be mindful of the specific minerals present and how they might interact with any medications you're taking. Some brands may even have artificially high mineral content, so checking the label is crucial.

Taste Profile: Due to its altered mineral composition, the taste of alkaline water can differ slightly from regular water. Some find it refreshing, while others may prefer the familiar taste of plain water.

Cost Factor: Let's face it, alkaline water often carries a higher price tag compared to tap water or filtered water. Consider this when deciding if it aligns with your budget and whether the potential benefits outweigh the cost.

The Alkaline Water Verdict: Hype or Hope?

Alkaline Water Verdict: Hype or Hope


Based on current research, there's no definitive proof that alkaline water offers significant health benefits for the majority of people. After all, our bodies are remarkably adept at maintaining a healthy internal pH balance.

However, if you enjoy the taste of alkaline water or experience occasional acid reflux, it might be a suitable choice for you. Just remember, it's not a magic elixir for optimal health and shouldn't replace a balanced diet and healthy lifestyle habits.
