One Of The Easiest Ways To Boost Your Immunity? With Water!

By sheer volume, your body is mostly water: 60% to be exact. Even your bones are about 30% water.1 

It should come as no surprise then that clean, pure water is absolutely crucial to keeping your body’s systems — including your immune system — running at peak performance.

Unfortunately, studies have found that about 75% of us are chronically dehydrated.2 Keep reading, and I promise you’ll be more motivated to buck the trend and hydrate for your immune health!

In this article:

Why Proper Hydration Is One of the Easiest Ways to Boost Your Immune Function

The amazing thing about having a body that’s mostly water is the unique opportunity to make major shifts in your health by simply improving your hydration. 

Drinking at least 2 quarts of clean, pure water keeps your immune system primed to respond to invaders quickly and effectively, as well as allowing your colon, skin, liver, and kidneys to flush waste and other toxins from your cells and organs efficiently and easily.

Studies show that even a one percent water deficiency3 places the body into a state of dehydration. Studies also show that immune function is suppressed in living organisms4 when the body detects water scarcity and becomes dehydrated. During periods of drought, animals from kangaroos to cattle show reduced capacity to fight off bacterial and viral infections5 as osmosis in cells becomes more difficult. 

When the body isn’t getting enough water, cell volume decreases, concentrations of antibodies go down, and the body’s ability to fight foreign pathogens is reduced. 

Water Quality: Just as Important as Quantity! 

Before you rush to fill a water bottle, consider this: While quantity of water consumption is critical, the quality of the water you drink matters as well. 

Filtered alkaline water (also known as “ionized water”) is the very best source of water for proper hydration and also offers some unique additional immune benefits (more on those benefits up next). 

This superiority is primarily because alkaline water helps fight two problems in one: dehydration and acidity. Our chemical, highly-processed world means that most of us have an overly acidic body pH — linked to reduced immune function, as well as a whole host of diseases including diabetes, acid reflux, cancer, and liver disease. 

Alkaline water, with its pH of 8 or 9 (out of 10) can help stabilize your body pH. 

Alkaline Water: How Boosting Your pH can Boost Your Immunity

Most of us are in desperate need of a pH boost. The standard American diet of animal proteins, processed foods, white flour and sugar, dairy, coffee, and soda, is incredibly acidic. This acidity puts a significant strain on the body’s systems6 as it fights to maintain the narrow window of pH (right about 7.4) that is optimal for immunity and health. 

As the body’s pH dips, enzymes struggle to remain active, digestion becomes more difficult, blood oxygenation drops, and pathogens that thrive in a low pH/low oxygen environment thrive — including many viruses,7 yeast, fungus, and bacteria. 

By eating a diet rich in alkaline foods (plant-based, unsurprisingly!) and hydrating with alkaline water, you can help your body maintain a stable, alkaline pH that is both inhospitable to foreign pathogens and conducive to a strong immune response. But high pH is just one reason alkaline water is the best choice for hydration and immune function. 

Additional Immune Benefits of Alkaline Water

In addition to boosting overall body pH, alkaline water has a few other unique properties that make it the ideal choice for both immune function and hydration: 

  1. Trace Minerals Like Magnesium and Calcium: Alkaline water fortifies your body with trace minerals like magnesium and calcium. Both calcium8 and magnesium9 play critical roles in activating and arming immune cells when an outside invader enters the body.
  2. Smaller Molecules for Rapid Hydration: Non-ionized water isn’t nearly as efficient in hydrating cells as ionized, alkaline water. Why? Because the molecule size of alkaline water is smaller and can be more easily absorbed by your cells! Studies of athletes show that alkaline water hydrates more effectively and rapidly10 than non-ionized water.  
  3. Oxygenates the Body: A body that isn’t properly oxygenated is vulnerable to disease of all types. Across the board, bacteria, viruses, and even cancer cells thrive in low-oxygen, acidic environments. Ionized, alkaline water has a significantly higher ratio of oxygen to hydrogen.11 Ionized water supplies your red blood cells with oxygen to deliver throughout your body to effectively combat invaders.
  4. Rich in Molecular Hydrogen: Ionized water is also rich in molecular hydrogen12 — a powerful antioxidant that can neutralize damaged, unstable atoms that cause inflammation throughout the body. An inflamed body is at greater risk for invading pathogens, since the body’s immune response is already being tapped by internal threats. 

I’ve written about other health benefits of alkaline water, including supporting healthy weight loss.

Where Can I Get Alkaline Water? 

“… a water ionizer… can be installed directly on your sink… It’s more cost effective, good for the environment, and you won’t feel the need to ration your expensive water!”

You may have seen bottles of alkaline water at your local grocery store. I recommend that you don’t purchase those. For one thing, they’re expensive, and for another, all that plastic is wrecking the environment and is produced using a plethora of chemicals. And ionized water can lose its charge sitting there in a plastic bottle. 

Instead of buying the alkaline water at the store, which will set you back more than $7 per gallon, I recommend a water ionizer that can be installed directly on your sink and costs about 17 cents per gallon. It’s more cost effective, good for the environment, and you won’t feel the need to ration your expensive water! 

The UV light that filters the water also gives you the added benefit of killing pathogens that might come from your water source. 

Conclusions on Hydration and Immune Function 

There’s no question that proper hydration—at least two quarts of clean, pure water per day—is vital to immune health. And by hydrating with alkaline water, you can double your immune support by hydrating your cells for proper function, reducing acidity that allows invaders to get a foothold more easily, and fortifying your system with plentiful trace minerals and oxygen vital to immune function.

    I have a water filter on my refrigerator would that be the same thing?

  2. Susan Riley says:

    I bought one of the Influence under-the-sink units. It now doesn’t put out any water the the unit says "0". Who do I contact about this? I think I must need a new filter and don’t know whom to call. I would appreciate information ASAP as we are fighting cancer and I feel this has really helped.

    Thank you!

    1. Hi Susan, please email with your concern. Thank you for reaching out.

      We wish you the best on your healing journey!
