About Kath P

Kath P is a writer, researcher and parent based in Sydney, Australia. She is the primary contributor to The Dew. Journal, where she covers the science of indoor mould and humidity — what causes it, what it does to your health, and what the evidence says actually works to prevent it.

Background

Kath has spent years researching indoor environmental quality with a particular focus on the moisture and mould conditions found in Australian homes. Her work draws on peer-reviewed research, WHO guidelines, building science studies and the real-world experiences of Australian renters, homeowners and families dealing with damp housing.

As a parent, she became acutely interested in the evidence linking early childhood mould exposure to asthma risk — a body of research she describes as "the studies that stick with you." That interest expanded into broader questions about prevention, remediation costs, renter rights, and the surprisingly strong case the science makes for keeping humidity in the safe zone before mould ever appears.

What she writes about

Kath's articles for The Dew. Journal cover:

• The health effects of indoor mould — from allergies and asthma to mycotoxins and cognitive effects
• How humidity works in Australian climates, season by season and city by city
• Evidence-based prevention strategies, drawn from WHO indoor air quality guidelines and building science research
• Renter rights and landlord obligations around mould in Australian states and territories
• Practical guides for protecting specific items — leather shoes, handbags, wardrobes, linen, children's rooms
