How adequate hydration supports your immune system

---

We are in the throes of winter, and for those of us in the southern half of the country, we know one or a few people with the sniffles or a full-blown cold or flu. While avoiding the dreaded lurgi is not easy and in no way are we suggesting that our water filters systems will insulate you from catching a bug, what is real is staying well hydrated helps your immune system defend itself.

Fresh, clean water does more than quench your thirst. H2O plays a crucial role in keeping our immune system working properly. The lymphatic system carries white blood cells throughout the body. These infection-fighting super cells need hydration to perform at their best. Water supports our kidneys and liver. These two organs flush toxins from the body; without them in tip-top shape, our immune response is compromised. And there are the mucous membranes in the respiratory tract. This membrane wards off airborne pathogens and requires hydration to act as our body’s front line defence.

Individuals must drink sufficient water every day. Giving your body quality filtered water is an extra layer of insurance for your health.

“Fresh, clean water does more than quench your thirst; H2O plays a crucial role in keeping our immune system working properly.”

It’s a fair question: Why not just drink tap water? At Water Filters Australia, we are advocates for drinking as much water as possible. It is particularly important for younger and older people. We are a fortunate country to have access to reasonably good water straight from the tap, and our regulatory framework is sound. However, this does not mean that tap water is free from contaminants or immune to broken pipes or issues with storage facilities. We’ve seen in recent years that some regional areas’ water is undrinkable due to deteriorating water infrastructure and distribution systems.

Tap water also has the potential to carry heavy metals. Lead and mercury, for example, can suppress the immune system over time. Chlorine is commonly used as a disinfectant; however, it and its byproducts can unbalance beneficial gut bacteria. And there are headline-grabbing “forever chemicals,” PFAS, which are becoming increasingly linked to suppressing the body’s immune system.

By filtering your tap water, these harmful elements are not entering your body and compromising your health.

In the old days, jumping off the top tower at the local swimming pool took guts. Thankfully, we now recognise our gut’s vital role in overall wellbeing and that “guts” is not just an expression of bravery. In fact, 70% of our immune system is in the gut. The gut’s microbiome is one of the most intricate communities of bacteria and microorganisms we possess to regulate our immune system, and the quality of drinking water directly affects its diversity and microbial balance.

Filtered water is your gut’s best friend. By minimising impurities and filtering out harsh chemicals, your gut has superior potential for creating a sturdy and high-functioning environment for microbiomes to succeed.

“Filtered water is your gut’s best friend.”

Why is hydration important for the immune system?

Hydration supports vital immune functions, including circulation of white blood cells, optimal kidney and liver function for toxin removal, and the maintenance of mucous membranes that defend against pathogens.

How does tap water compare to filtered water?

While tap water in Australia is generally safe, it can still contain contaminants such as heavy metals, chlorine, and PFAS, which may impair immune function over time.

What role does the gut play in immune health?

Around 70% of the immune system resides in the gut, and its health is directly influenced by the quality of water consumed—filtered water helps maintain a balanced gut microbiome.

Are water filters hard to install?

No. Water Filters Australia systems are DIY-friendly and can be installed in under 30 minutes using basic tools and an online guide.

Is filtered water necessary if my tap water tastes fine?

Even if tap water tastes fine, filtering adds an extra layer of protection by removing impurities that may affect long-term health and immune function.

Hydration is essential to immune defense. It ensures efficient transport of immune cells and optimal detoxification processes.

Kidney, liver, and respiratory functions depend on water. These systems rely on hydration to flush toxins and block airborne pathogens.

Filtered water enhances gut health. By reducing chemicals and contaminants, it fosters a healthier environment for microbiomes.

Tap water quality can vary. Despite regulation, tap water may still contain harmful substances like lead, chlorine, and PFAS.
