Most Australians who care about water quality focus entirely on what they drink. That makes sense — we think of ingestion as the primary route of exposure to contaminants.
But here's a fact that changes everything: your skin absorbs water and its contents during every shower. And for certain chemicals — chlorine and chloramines in particular — the exposure through bathing can actually exceed the exposure through drinking.
### The Absorption Problem
Your skin is a remarkable barrier against many things. But it is not impermeable to all chemicals, and it is especially permeable when warm and wet — exactly the conditions of a shower.
When you shower in chlorinated water, two things happen simultaneously:
**Dermal absorption:** Chlorine and chloramine compounds penetrate the skin and enter the bloodstream directly, bypassing the digestive filtering system that at least partially processes contaminants from water you drink.
**Inhalation:** Hot water causes chlorine compounds to vaporise rapidly. The steam in your shower is rich in vaporised disinfectant chemicals and their by-products, including chloroform and other trihalomethanes (THMs). You breathe these in directly through your lungs — another high-absorption pathway that completely bypasses your gut.
Research from the 1990s and 2000s — including work published in the American Journal of Public Health — found that showering in chlorinated water was associated with measurable blood levels of THMs, with some studies suggesting shower exposure was as significant a contributor to total THM body burden as drinking water.
### What Chlorine Does to Skin and Hair
Beyond the systemic absorption concern, the more immediate and visible effects of showering in chlorinated water are well documented:
**Skin dryness and irritation:** Chlorine strips the skin's natural lipid layer — the protective film of oils and ceramides that keeps moisture locked in and bacteria out. Regular chlorinated showers are a well-recognised trigger for dry, itchy, and sensitive skin. For people with eczema or psoriasis, chlorinated water is a documented aggravating factor.
**Disrupted skin microbiome:** Your skin hosts hundreds of species of beneficial bacteria that form part of your immune defence. Chlorine is indiscriminate — it kills bad bacteria in water, but it also disrupts the delicate balance of microorganisms on your skin's surface, contributing to skin conditions and reduced barrier function.
**Hair damage and dryness:** Hair is particularly vulnerable to chlorine because the cuticle — the outer protective layer — opens in warm water, allowing chlorine to enter and damage the hair shaft. Colour-treated hair fades faster. Natural hair loses elasticity and shine. The scalp, stripped of its natural oils, often overcompensates by producing excess sebum — leading to greasiness at the roots and dryness at the ends.
**Premature ageing:** Oxidative stress is one of the primary mechanisms of skin ageing. Chlorine is an oxidising agent. Regular exposure accelerates the oxidation of skin cells — contributing to fine lines, loss of elasticity, and dullness over time.
### Children Are More Vulnerable
Children have thinner, more permeable skin than adults, and a higher surface-area-to-body-weight ratio. This means they absorb proportionally more of whatever is in the water per kilogram of bodyweight. For parents who have already filtered their family's drinking water, adding a shower filter is the logical and often overlooked next step.
### What a Quality Shower Filter Does
A quality shower filter removes or significantly reduces:
- **Free chlorine** — the primary disinfectant and skin irritant
- **Chloramines** — the more complex disinfectant compound increasingly used in Australian cities, harder to remove than chlorine alone
- **THMs and other disinfection by-products** — vaporised compounds inhaled during showering
- **Heavy metals** — including lead and copper that leach from household pipes
- **Sediment and particulates**
The results most people report after switching to a shower filter are immediate and tangible: skin feels softer within the first week, hair is more manageable and lustrous, dry and itchy skin conditions frequently improve, and many people notice they feel less depleted after showering.
### The Complete Approach to Clean Water
True clean water in the home means addressing water at every point of use, not just the kitchen tap.
At Alkaline World, we carry shower filters alongside our full range of drinking water systems precisely because the science is clear: your skin and lungs are exposure pathways that matter. A family that drinks the Aquarius M25 water and showers in filtered water has comprehensively reduced their chemical water load — in the ways that make the most difference to long-term health.
The investment is modest. The impact — on your skin, hair, energy, and long-term toxic burden — is real.
