- Dr. Nicole Bijlsma explains why the built environment matters for health, from mould and air quality to electromagnetic fields and chemical exposures. She shares practical, high-impact changes for bedrooms, water, skincare, cleaning, and home setup that can reduce everyday exposure and support better sleep, immunity, and wellbeing. We discuss why old homes and new homes each have different risks, how Wi-Fi and electrical wiring can affect sleep, and why water filtration is a non-negotiable if you want to reduce chlorine, PFAS, and fluoride exposure. Nicole also covers the biggest chemical exposures on skin, the most useful cleaning swaps, and why over-sanitising may be backfiring on allergy risk.
Key topics
Nicole shares how personal health issues led her into building biology and why she started training people to assess homes for environmental hazards.
The difference between old homes and new homes, including condensation, mould, poor maintenance, tight building envelopes, and off-gassing from imported furnishings.
Why carpets can act like a reservoir for dust, pest debris, asbestos, lead paint, and chemicals, especially for infants crawling on the floor.
The three EMF categories Nicole prioritises - radio frequencies, AC magnetic fields, and dirty electricity.
Why a Wi-Fi router in the bedroom is a major issue, and why hardwiring or powering routers down at the wall is the best fix.
Why the bedroom is the top health priority, and how to set it up for better sleep by removing Wi-Fi devices, phones, extenders, and boosters.
Why inverter and solar battery placement matters, and why distance is the main defense against magnetic fields.
Why reverse osmosis is the best option for drinking water when fluoride is a concern, while whole-house filtration helps with chlorine, sediment, PFAS, and many other contaminants.
Nicole shares why alkaline water is not her recommendation, and why stomach acid matters for digestion, protein breakdown, and nutrient absorption.
The biggest chemical exposures on the body, especially perfumes, aftershaves, artificial fragrances, and air fresheners.
Why jojoba oil, rose hip oil, wool, hemp, cotton, and fragrance-free basics are the safer everyday choices for skin and home use.

Action items
Remove Wi-Fi enabled devices, extenders, boosters, and phones from the bedroom.
Put the router on a timer or power it down at the wall overnight.
Move the bed away from the wall closest to the meter panel or incoming electrical supply.
Prioritise whole-house water filtration, and add reverse osmosis at the kitchen sink if fluoride is a concern.
Switch to fragrance-free personal care and cleaning products.
Use microfiber cloths, detergent, and a sealed HEPA vacuum for routine cleaning.
Favor natural materials like wool, hemp, cotton, and jojoba-based skin care where possible.
Reduce over-sanitising at home and let kids get normal outdoor dirt exposure.

Carly is a counsellor and coach who specialises in building psychological hardiness, which is the ability to navigate challenge, stay engaged, and take meaningful action under pressure. Her work integrates modern psychology with Eastern and Stoic approaches, helping people build resilience, live with purpose, and respond to life’s challenges with greater clarity, courage and steadiness.
See omnystudio.com/listener for privacy information. - Most addiction advice is built for rock bottom. Tara Hurster says that misses the vast majority of people - the high-functioning drinkers, gamblers, and users who still have jobs, houses, and families, but know something is off. If you’ve ever wondered where “just a bit too much” becomes a real problem, this conversation gives you a clearer answer than shame ever could. Paul speaks with Tara Hurster, psychologist and founder of The TARA Clinic, about the low-to-high risk continuum of addiction, the 12 DSM criteria, and why “stopping” is not the same as changing. . Her approach is practical, non-judgmental, and built around helping people make real choices with real tools - not just white-knuckle their way through. Tara breaks down how tolerance, repeated failed attempts to cut down, negative consequences, and defensiveness can all signal a deeper issue, even when life still looks functional from the outside.
You’ll discover:
Why addiction can be invisible in high performers and professionals
How the stages of change model explains denial, preparation, action, and maintenance
The “stop you swap” trap and why focusing only on abstinence creates a void
Why relapse is better understood as recycling, and relapse as a lesson
How identity, values, and stress management drive the behaviours people keep repeating
