Your heart is a 24/7 powerhouse—no lunch breaks, no sick days, just a lifetime of keeping you going. The least we can do is give it the care it deserves. We know the usual checklist: eat well, stay active, sleep enough. But one often-overlooked factor? Hydration.

Drinking water is a key player in your heart health. And here’s something that might surprise you: the kind of water you drink matters. Tap water often carries sneaky nasties that can make your heart work harder, while clean, filtered water gives it the hydration it needs without the hidden extras. If you’re already making an effort to drink enough water, why not make sure it’s the best quality possible? Here’s why filtered water could be one of the simplest, most effective ways to support your heart.

Why Hydration is Key to Heart Health

Your heart is about 73% water, so it makes sense that proper hydration is essential for keeping it in top shape. But how exactly does drinking water benefit your heart? Here’s the breakdown:

If your heart could talk, it would probably say, "More water, please!"—and filtered water is the way to go.

The Role of Filtered Water: Why It’s Better for Your Heart

Just because your water looks clear doesn’t mean it’s free from unwanted extras. Tap water, while convenient, can contain substances that aren’t doing your heart any favours. Here’s why filtered water is the better choice:

  • Removes Contaminants – A good water filter eliminates chlorine, heavy metals (like lead and mercury), and microplastics that can contribute to oxidative stress—a known factor in heart disease.

  • Balances pH Levels – Filters like ours at Earths Water enhance water’s alkalinity, helping to maintain your body’s acid-base balance and reducing strain on the heart.

  • Improves Hydration Efficiency – When water tastes pure and fresh, you’re more likely to drink enough, keeping your heart properly hydrated.

Who’s Most at Risk & How Clean Water Can Help

Heart attack is a major health concern in Australia, with over 4 million Australians affected and heart attacks being a leading cause of hospitalisation and mortality. While there are many factors at play, something as simple as proper hydration can make a difference. For some groups, staying well-hydrated with clean, filtered water is essential for supporting heart health. If you fall into one of these categories, making the switch to filtered water could be a game-changer.

Older Adults

As we age, our bodies become less efficient at retaining water, making dehydration a common issue. This puts extra stress on the heart. Filtered water helps by ensuring hydration without exposing the body to unnecessary contaminants.

People with High Blood Pressure

If you have hypertension, you already know how important it is to manage your sodium intake. But did you know some tap water contains sodium? A high-quality filter removes excess sodium and other unwanted elements, ensuring your water supports your health rather than sabotaging it.

Those with a Family History of Heart Disease

Genetics play a role in heart health, so taking preventive steps is key. Drinking filtered water ensures you’re not exposing your body to harmful substances that could add stress to your cardiovascular system.

People with Obesity

Obesity is a well-known risk factor for heart disease and increases the likelihood of high blood pressure and cholesterol issues. Proper hydration with clean, filtered water supports metabolism, aids in weight management, and helps the heart function more efficiently.

Smokers and Heavy Drinkers

Smoking and excessive alcohol consumption can dehydrate the body and introduce toxins that put pressure on the cardiovascular system. Staying hydrated helps support the body’s natural detoxification processes and reduces the risk of heart-related complications.

People with Diabetes

Diabetes increases the risk of heart disease, and dehydration can make blood sugar levels harder to control. Drinking filtered water helps maintain hydration without the risk of consuming contaminants that may interfere with overall health.
