The link between water quality and baby eczema
A major study in the Journal of Allergy and Clinical Immunology (2022) found that infants in hard water areas had an 87% higher risk of developing eczema by 3 months of age.
NHS guidance: Acknowledges that hard water and chlorine can worsen eczema and recommends unperfumed bath products and, where possible, filtered water for sensitive cases.
Why babies are more vulnerable
A baby's skin is 30% thinner than adult skin, with a less developed barrier. Chlorine penetrates more easily and disrupts the skin microbiome — a key eczema trigger.
Practical steps
- Install a shower/bath filter — the most impactful change
- Use lukewarm (not hot) water — under 37°C
- Pat dry gently, never rub; moisturise within 3 minutes
- Use unperfumed, soap-free wash products
- Keep bath time under 10 minutes
