Healthy Choices in Clothing and Bedding

June 2026 

What we wear — and sleep in — has a closer connection to our health than many people realise. Clothing and bedding sit against our skin, our body’s largest organ, for many hours every day. In fact, we spend around one-third of our lives in bed, making the materials we sleep amongst just as important as the clothes we wear.

Organic and natural fibres such as organic cotton, bamboo, hemp, linen and wool are generally produced with far fewer pesticides and synthetic chemicals than conventional fabrics. Conventional cotton is one of the world’s most chemically intensive crops, using large amounts of pesticides, herbicides and water. Synthetic materials such as polyester, nylon and acrylic are petroleum-based, shed microplastics and often contain chemical finishes linked to skin and respiratory irritation.

Bamboo clothing has become increasingly popular because of its soft feel and breathability. Quality bamboo fabrics can be comfortable for sensitive skin and are often favoured by people wanting lower-tox alternatives. Organic cotton and bamboo bedding may also help create a healthier sleep environment by reducing exposure to synthetic chemicals during the many hours we spend resting and recovering.

From an environmental perspective, organic fabrics can dramatically reduce carbon footprint, pesticide use and pollution. Hemp and linen require less water and fewer agricultural chemicals than conventional cotton.

Ethical sourcing is equally important. Many ultra-cheap multinational fashion retailers have faced criticism regarding exploitative labour practices and supply chains. Supporting ethically made Australian-focused brands helps promote healthier working conditions, sustainability and product quality.

In our home, we’ve been sleeping in organic pyjamas and bedding by Blessed Earth for over a decade, as well as wearing Boody organic bamboo and Bhumi organic cotton garments. If you can recommend any other Australian organic brands, please reach out and let me know.

Forever Chemicals in Everyday Living

“Forever chemicals,” known scientifically as PFAS (per- and polyfluoroalkyl substances), are increasingly recognised as a hidden health concern in modern homes. These chemicals are called “forever” because they do not break down easily in the environment or the human body, meaning exposure can accumulate over time.

According to the National Health and Medical Research Council, PFAS are widely used in products such as non-stick cookware, stain-resistant fabrics, carpets and water-repellent clothing. They are also found in drinking water, personal care products and even some sleepwear.

In the home, for example, that convenient non-stick surface or spill-proof fabric may come at a cost, with research linking PFAS exposure to hormone disruption, altered immune and thyroid function, liver disease, lipid and insulin dysregulation, kidney disease, adverse reproductive and developmental outcomes and cancer.

Australian authorities recommend a precautionary approach and minimising exposure where possible. In the kitchen, consider replacing non-stick cookware with safer alternatives such as cast iron, stainless steel, or high-quality ceramic.

Drinking water is another important consideration, and using a high-quality water filtration system, such as reverse osmosis filters, is recommended.

For sleepwear and clothing, choose organic cotton, linen, or bamboo fabrics that are breathable and free from chemical treatments. Avoid items labelled “stain-resistant” or “wrinkle-free”, as these often rely on PFAS-based coatings.

Soft furnishings, like carpets, curtains, and lounges are best made from natural fibres such as wool, cotton, or hemp, without added stain protection. Reducing plastic use—particularly in food storage—can also help, with glass and stainless-steel offering safer alternatives.

Finally, take a closer look at personal care products. Choose simple, low-tox options with minimal ingredients, and avoid products marketed as long-lasting, waterproof, or stain-resistant, as these may also contain PFAS.

Creating a healthier home does not require perfection—just informed choices. By gradually replacing high-risk items, you can meaningfully reduce your exposure and support a safer indoor environment for your family.

Healthy House Cleaning

First published in Woopi News April 2026 

A clean home should support your health, not compromise it. Many conventional cleaning products contain synthetic fragrances, harsh solvents and other chemicals that can contribute to indoor air pollution, irritate the respiratory system and harm the environment. The good news is that maintaining a healthy home does not require a cupboard full of chemical cleaners.

The low-tox living movement encourages simplifying cleaning routines and choosing safer ingredients. In many cases, simple natural substances work extremely well. A basic all-purpose spray can be made using diluted vinegar and water, while baking soda works well as a gentle scrub for sinks, tiles and baths. Microfibre cloths and warm water alone can also remove a surprising amount of dirt without the need for harsh chemicals.

A key principle of low-tox cleaning is avoiding vague ingredients such as “fragrance” or “parfum”, which may contain numerous undisclosed chemicals. Instead, look for products with transparent ingredient lists and simple formulations.

In our home, we compliment the low-tox home cleaners with a probiotic cleaning spray, dishwashing concentrate and laundry liquid made on the Gold Coast by One Organic.

Equally important is the equipment used for cleaning, particularly vacuum cleaners. For healthier indoor air, a good vacuum should include a turbo head to agitate dust from carpets, electrostatic replaceable bags to trap particles, and a HEPA filter to capture very fine dust and allergens. These features help prevent fine dust from being released back into the air while vacuuming.

Building biologists also recommend using a vacuum cleaner dedicated to your home. When cleaners bring the same vacuum between different houses, dust, mould spores and allergens can potentially be transferred between homes.

One excellent option recommended within the building biology community is the Pacvac Hush. We recently purchased one ourselves and have found it to be very effective. It is quiet, medical-grade, and designed for excellent dust containment.

Healthy cleaning does not need to be complicated. By choosing low-tox products and effective equipment, you can reduce chemical exposure, improve indoor air quality, and create a home that truly supports wellbeing.

Natural Weed Control That Supports a Healthy Home Environment

First published in Woopi News in March 2026

For many households, creating a healthy home doesn’t stop at the front door. Our gardens, lawns and driveways are part of our living environment — and what we use outside can affect soil health, waterways and ultimately our families.

With glyphosate classified by the International Agency for Research on Cancer as “probably carcinogenic to humans” (Group 2A), more families are looking for ways to manage weeds without relying on synthetic herbicides. The good news is that effective, low-tox strategies can keep gardens tidy and productive while supporting ecological health.

Start with Prevention

One of the most effective weed strategies is prevention. Rather than constantly battling established weeds, aim to create conditions where they struggle to gain a foothold.

In lawns, allow grass to grow slightly longer to shade the soil surface. This simple adjustment reduces light reaching weed seeds and slows their germination. Overseeding with clover or other low-growing species can also help. Clover naturally suppresses weeds while adding nitrogen to the soil, improving lawn resilience without synthetic fertilisers. As an added benefit, flowering clover attracts bees and other pollinators — essential partners in a healthy garden ecosystem.

In garden beds, apply a generous layer (5–8 cm) of weed-free organic mulch such as straw, bark or woodchips. Mulch blocks sunlight, reduces weed germination, retains moisture and gradually improves soil structure as it breaks down.

Low-Tox, Targeted Removal

When weeds do appear, early action makes all the difference. Hand weeding and simple tools like hoes remain some of the safest and most precise options — particularly when weeds are removed while young and before they set seed. This prevents the next generation from establishing.

For paths, paving and driveway cracks, many natural living advocates use spot treatments such as household vinegar combined with a small amount of natural soap. This solution can dehydrate soft annual weeds without leaving long-lasting chemical residues in soil. Carefully pouring boiling water directly onto weeds in cracks is another simple, low-tech method that avoids synthetic chemicals altogether.

Smother and Restore

For more persistent problem areas, consider “sheet mulching.” This involves laying cardboard directly over weeds and topping it with compost and mulch. Over time, the weeds break down beneath the barrier, and the area can be transformed into a fertile garden bed — no spraying required.

Some organic growers also use flame weeding tools, which briefly pass heat over young weeds to rupture their cells. The process avoids chemical application and can be effective when used carefully and responsibly.

Building Resilient Gardens

Healthy soil, diverse plantings and regular light maintenance create resilient gardens where weeds are manageable rather than overwhelming. By working with natural systems instead of against them, we reduce chemical exposure around our homes while protecting local waterways and soil life.

Thoughtful, low-tox weed management is another practical step toward creating a healthier home environment — inside and out.

Eat Real Food

First published in Woopi News in February 2026

Last month, I suggested some simple food swaps for healthier eating. I don’t think the US Departments of Agriculture and Health and Human Services read my article, but I am pleased that their new recommendations reflect my healthy home tips. Given the new Dietary Guidelines were only released in mid-January, I wanted to share them with the Woopi community this month.

The new US “Eat Real Food” pyramid for 2026–2030 flips older low‑fat, high‑carb advice on its head, putting protein, healthy fats, and whole foods back at the centre of everyday eating. While it is aimed at Americans, many of the ideas translate well to Australian kitchens and lunchboxes.​

What the new pyramid says

• Protein, dairy and healthy fats sit at the largest tier, with a suggested 1.2–1.6 g of protein per kilogram of body weight per day from both animal and plant sources.​

• Vegetables and fruits share equal billing, with guidance to eat them in whole form across the day rather than as juices or ultra‑processed snacks.​

• Whole grains are pushed to a smaller base, and refined carbohydrates, added sugars and highly processed foods are strongly discouraged.​

Why it matters for Aussies

• The guidelines are framed as a response to soaring chronic disease, calling out ultra‑processed foods as a major driver of poor health. Australia faces similar trends in obesity, diabetes and heart disease, so the “real food first” message is highly relevant here.​

• The model also re‑emphasises food, not medication, as the everyday foundation for better metabolic and mental health.​

Simple swaps at home

For Woopi households, that can look like:

• Building meals around eggs, seafood, meat, legumes, nuts, yoghurt and cheese, then adding colourful veg and a piece of fruit.​

• Choosing oats, brown rice or true wholemeal bread instead of breakfast cereals, pastries and white bread.​

• Cooking with olive oil, ghee or coconut oil and skipping deep‑fried takeaway and packaged “diet” foods.​

Framed this way, the new pyramid is really a nudge back to what grandparents in Woolgoolga would recognise: mostly home‑cooked, minimally processed, real food on the table.

Simple Ingredients Swaps for Healthier Eating

First published in Woopi News in January 2026

Creating a healthier home does not have to mean complicated diets or expensive specialty foods. Often, it is the small daily choices that make the biggest difference. One of the easiest places to start is in the kitchen. By replacing common processed ingredients with nourishing whole-food alternatives, you can boost energy, reduce inflammation, and support your family’s long-term wellbeing — all while enjoying fresh, delicious meals.

Here are some simple swaps you can begin using today:

• Alcohol: Choose organic fermented drinks such as kombucha, or opt for organic wine, sake or honey mead.

• Bread: Trade white bread for organic whole sourdough, sprouted breads, buckwheat wraps, buckwheat pancakes, millet roti, or simple nori rolls.

• Breakfast cereals: Replace sugary boxed cereals with buckwheat, quinoa or millet porridge, granola, Bircher muesli, or steel-cut oats.

• Caffeine: Swap coffee and black tea for cacao or teas such as chamomile, mint, nettle, green, jasmine or roasted dandelion root.

• Desserts: Skip ice cream and cake by choosing avocado chocolate mousse, coconut-based non-dairy ice cream, or rice and quinoa puddings.

• Drinks: Replace soft drinks with freshly squeezed juice, or fresh lime and sparkling water with ginger and mint.

• Milk: Instead of conventional milk, try organic fresh milk, or almond, macadamia or Brazil-nut milk.

• Milkshakes: Enjoy nutrient-dense smoothies or fresh vegetable and fruit juices.

• Pasta: Try spiralised raw vegetables, or choose 100% rice or buckwheat noodles.

• Salt: Use unrefined sea salt, seaweed flakes, miso, tamari or organic soy sauce.

• Snacks: Replace chips, dips and packaged sweets with activated nuts, flaxseed or buckwheat crackers topped with pesto, hummus, olive tapenade, guacamole, salsa verde, organic pâté or homemade kale chips with sea salt.

• Spreads: Swap margarine for organic butter, hummus, or mashed avocado.

• Sweeteners: Replace white sugar with stevia, raw honey, coconut sugar or pure maple syrup.

Small changes add up. Start with crowding out the unhealthy foods with more of the healthy options. When shopping, aim to make one swap each week, build from there, and enjoy feeling the difference in your body and your home.

Vitamin D & Sunscreen Can We Have Both?

First published in Woopi News in December 2025

As the weather warms up, it is a great time to discuss vitamin D and sun protection. Most Australians know that sunshine is essential for vitamin D, but far fewer realise just how vital this nutrient is — or how our choice of sunscreen can influence health. Vitamin D deficiency is linked to a wide range of chronic conditions, including fatigue, depression, autoimmunity, low immunity, bone loss, metabolic issues, and hormonal imbalance. Managing sun exposure wisely while protecting your skin is essential for good health.

The sun emits two main types of ultraviolet radiation: UVA and UVB. Vitamin D production relies specifically on UVB radiation, which makes up less than 5% of total UV rays, and prevails when your shadow is shorter than you, typically between 10am and 4pm. UVB is powerful — it enables vitamin D synthesis but is also the primary cause of sunburn and DNA damage that can lead to skin cancer. UVA acts differently: it penetrates deeper into the skin and can inhibit vitamin D production, helping to regulate levels.

Choosing the right sunscreen helps ensure we stay protected without blocking all beneficial UVB. Studies show that broad-spectrum sunscreens, which protect against both UVA and UVB, are the most effective overall, as they enable better vitamin D synthesis than a product that only protects against sunburn. Individual UVB doses necessary for maintaining optimal vitamin D levels are lower than those that cause sunburn, regardless of skin tone.

Sunscreen ingredients matter. Common chemical UV filters such as oxybenzone and octinoxate are linked to negative effects on human and environmental health, and have been banned in some US states, including Hawaii. The US Environmental Working Group (EWG) have reported “The Food and Drug Administration, which oversees sunscreen safety, said in 2021 that out of 16 ingredients it reviewed, only two – zinc oxide and titanium dioxide – are “generally recognized as safe and effective,” or GRASE, based on the available information”. Zinc oxide offers broad spectrum protection, while titanium dioxide predominantly protects against UVB.

A helpful way to choose safer sunscreen options is to check their rating on the Yuka app or EWG’s Skin Deep website, which score products for health impacts. While my Miessence Reflect Outdoor Balm has not been assessed, I will continue to use it, as it is a mineral zinc-based sunscreen that has been my product of choice for over ten years.

This summer, aim for a healthy balance: sensible sun exposure, thoughtful skin care, and safer sunscreen choices that support your wellbeing — not undermine it.

Who’s in Bed with You? House Dust Mites

First published in Woopi News in November 2025

Do you believe me? Let’s pull back the covers and see who’s living under your sheets.

House Dust Mites (HDMs) thrive where there’s moisture, warmth, and food. They can’t drink water, so they absorb it from the air — or from sweaty bedding throughout the night — once relative humidity exceeds 55%. They prefer temperatures above 25°C (like a warm bed) and feed on human and pet dander (shed hair and skin cells), cellulose from textiles (such as curtains, carpets, and soft toys), as well as pollens and microbes.

Fun fact: Each person sheds enough skin cells to feed around one million HDMs every single day. What’s wrong with sharing your bed with millions of Dust Mites? Nothing — unless you’re allergic to them. HDMs don’t bite, spread disease, or cause health problems unless you’re sensitive to their allergens. However, HDM allergy affects around 22% of the population, making it one of the most common allergies worldwide.

Around 85% of asthma sufferers are allergic to HDMs, which are also a leading cause of hay fever and allergic asthma. HDMs produce and excrete numerous allergens, including proteins and microbial by-products found in their faeces. Speaking of faeces, they produce around 40 trillion faecal pellets in a mattress every three months.

Symptoms of HDM allergy include itchy or watery eyes, sneezing, an itchy, runny, or blocked nose, dry persistent cough, wheezing, and eczema. Symptoms tend to worsen at night or upon waking. Unlike pollen allergies, HDM allergies aren’t seasonal — but symptoms vary with humidity and temperature indoors, and usually improve when you’re away from the source.

Solutions for Reducing Dust Mites:

If you suffer from HDM allergies and are ready to take control, start with the bedroom — it’s their favourite habitat.

1. Reduce HDM levels by replacing carpet with hard flooring; and curtains with timber or metal blinds that can be wiped with a slightly damp microfibre cloth.

2. Maintain indoor humidity between 40–55% using a dehumidifier or refrigerated air conditioner.

3. Discard old soft furnishings. Replace mattresses and wool or feather-filled doonas every ten years, and pillows every two years.

4. Wash sheets and pyjamas weekly in hot water (at least 55°C), and pillows, blankets, and doonas every two months. Choose washable toys for children with HDM allergies. Air rugs, bedding, and mattresses outside on hot, dry days whenever possible.

5. Don’t make the bed straight away. Leave the covers off in the morning to let the mattress dry out.

6. Vacuum daily with a HEPA-filtered vacuum that has a motorised head and electrostatic disposable bags — HDMs love living inside vacuum cleaners!

7. If changing sheets, vacuum your mattress immediately after getting out of bed, when mites are close to the surface.

8. Store seasonal items in space bags, removing air to kill HDMs.

9. Avoid bunk beds for allergy sufferers, especially the bottom bunk, where airflow is restricted and mites thrive.

You might not see them, but house dust mites are among the most common roommates in Australian homes. With a few smart changes to your bedroom environment, you can reclaim your space — and your sleep — from these microscopic freeloaders.

Choosing Safer Fresh Produce

First published in Woopi News in October 2025

In September 2025, ABC News brought to light something that I found very concerning. Food Standards for allowable pesticide levels in fresh produce in Australia are calculated based on consumption. This means levels are higher for herbs, which are eaten sparingly, and lower for high-consumption foods, such as apples. While this system might seem acceptable in theory, a problem arises when the data being relied upon for the calculations is from the 1995 National Consumption Survey. Have you noticed changing consumption trends in the last 30 years? I have, and one example is in the consumption of blueberries, which was the focus of the 7 September 2025 ABC News article.

The article estimated that Australians now eat 3-10 times more blueberries than we did in 1995, and the levels of pesticides, including dimethoate, a potent neurotoxin that is banned in Europe, ingested by a child could place their intake above what is considered “acceptable”, after only a handful of berries. These levels are equally concerning for pregnant women; and they do not consider exposures from other foods eaten in combination.

In our home, we follow the US Environmental Working Group’s Clean 15 and Dirty Dozen lists (ewg.org), to guide us through the overwhelm when sourcing fresh produce. While certified organic and biodynamic are the gold standards, options can be limited and expensive. These lists highlight the foods which are likely to have high pesticide loads, and those which tend to have low levels of pesticides. My rule of thumb is that foods with thick skins, being less susceptible to pests, are generally sprayed less, and therefore buying organic may not be as imperative as it is for the fruits and vegetables on the Dirty Dozen list.

Dirty Dozen (buy organic if possible):

Strawberries,Spinach, Kale/Collard/Mustard Greens, Grapes, Peaches, Pears, Nectarines, Apples, Bell (Capsicum) & Hot Peppers, Cherries, Blueberries, Green Beans.

Clean 15 (safer to buy conventional):

Avocados, Sweet Corn, Pineapples, Onions, Papayas, Sweet Peas (frozen), Asparagus, Honeydew Melon, Kiwi, Cabbage, Mushrooms, Mangoes, Sweet Potatoes, Watermelon, Carrots.

Practical Tips for a Healthy Home

1 Wash thoroughly: Bath sprayed produce for 15 minutes in a vinegar and water bath (1:4) or spray with vinegar, wait 2 minutes, then scrub.

2 Peel when possible (if not organic).

3 Buy local and seasonal: Often less chemical input, shorter storage.

4 Use the Dirty Dozen / Clean 15 guides, updated annually from ewg.org.

5 Diversify your diet: Rotate produce to reduce repeated exposure.

6 Support stronger standards: Stay informed and ask shops for transparency.

Everyday Products, Hidden Risks

First published in Woopi News in September 2025

Have you ever read the ingredients of your household and cosmetic products? Do words like “2-bromo-2-nitropropane-1,3-diol” concern you? Did you know that “fragrance” (or “parfum”) on a label is an umbrella term that companies can legally use to protect their trade secrets? Here is a breakdown of six toxic ingredients in common personal care and cleaning products, where they are found, and what harm they could be doing.

1.       1-4-dioxane is a by-product of a chemical process where ethylene oxide, a known breast carcinogen, is added to other chemicals to reduce their harshness. It is a probable human carcinogen (IARC) from low-level exposure, and higher acute exposures can cause liver, kidney and respiratory damage. Found in shampoos, conditioners, skin care, personal care, laundry detergents and household cleaners. Avoid: Any ingredient with “eth” in the name e.g. sodium laureth sulphate.

2.       Nitrosamines are also classified as probable human carcinogens (WHO) and are found in cosmetics, skin care, personal care and hair care products. Avoid: MEA, DEA, TEA.

3.       Phthalates are commonly used as solvents in fragrances (parfum) to enhance scent. They are endocrine disruptors that can harm the developing foetus and male testes. Long-term exposure causes liver and kidney damage. High level exposure causes irritation to the eyes, nose and throat, nausea, vomiting, dizziness and headache. Found in air fresheners, perfumes, cosmetics, hair spray, nail polish and cleaning products. Avoid: Fragrance (Parfum), DBP, DEP.

4.       Parabens are used as preservatives in cosmetics, pharmaceuticals and foods. They are hormone disruptors and reproductive toxins. Found in deodorants, cosmetics, shampoos, moisturisers, shaving gels, toothpaste and cleaning products. Avoid: Methyl, Ethyl, Propyl and Butyl Paraben, Japanese Honeysuckle Extract.

5.       Formaldehyde is a known human carcinogen (IARC) and central nervous system depressant. Low level exposure causes eye, nose and throat irritation and can cause skin and lung allergies. Found in detergents, cosmetics, shampoos, bubble baths, hair conditioners, mouthwashes and skin disinfectants. Avoid: Sodium hydroxymethylglycinate, Imidazolidinyl urea, Diazolidinyl urea and 2-bromo-2-nitropropane-1,3-diol.

6.       Triclosan accumulates in our bodies and causes skin irritation, allergic reactions, endocrine disruption, and has potential links to cancer and antibiotic resistance. Found in antibacterial soaps, deodorants, toothpastes, cosmetics.

While this information may seem overwhelming, the good news is there are apps like Yuka Food & Cosmetic Scanner that you can use to scan a barcode and receive a health score out of 100. I just scanned the Miessence toothpaste I use and was pleased to see a score of 100/100! If apps are not your thing, a Certified Building Biologist can assist you in choosing personal care and cleaning products that help you create a healthier home.

Could mould be making you sick?

First published in Woopi News in August 2025

It has been a wet year for Woolgoolga and the surrounding Mid North Coast. With months of heavy rainfall and consistently high humidity, local homes have become prime environments for mould growth. Many residents are reporting musty odours, spotting on walls or ceilings, and even unexplained health symptoms. To make matters worse, mould can be growing in a home without displaying visible signs or smells. Advanced gene screening has revealed that 24% of the population cannot produce antibodies to fungi (mould), making these individuals susceptible to ill-health associated with mould exposure.

Mould spores are everywhere—but when indoor humidity rises above 60% relative humidity (RH), and materials are exposed to moisture (including water vapour) for more than 48 hours, mould will flourish. The risk to susceptible individuals from mould exposure is influenced by the porosity of the material, with non-porous items e.g. windows, posing a low health risk, and porous materials e.g. carpet, posing a higher risk of adverse health outcomes. The size of the affected area is also important, with areas greater than 1m2 correlating with more adverse health effects.

Symptoms of mould-related illness vary but often include persistent headaches, sinus congestion, coughing, asthma or allergies (such as hay fever and eczema), chronic fatigue, and sleep disturbances. Those with underlying conditions or sensitivities may experience more severe symptoms and find little relief until they are out of the affected environment and undergoing medically supervised detoxification.

Consider where you and your family members spend time. If there is an unwell person in your home, are they sleeping in a room on the southern side of the home, where sun exposure and air flow are limited? Is there adequate ventilation? Could their workplace, school, or other frequented buildings be mould-affected?

To reduce risk:

• Use a dehumidifier to keep indoor RH below 60%.

• Ventilate rooms daily, especially bathrooms and kitchens.

• Remove visible mould with caution—there are evidence-based protocols for remediating mouldy homes and contents, depending on the porosity of the material.

• If health concerns persist, do not just guess. Contact a Certified Building Biologist to assess your home for hidden moisture and mould issues.

A healthy home supports a healthy body. If you suspect mould is contributing to your family’s symptoms, act today. Prevention, proper assessment, and targeted remediation can make all the difference.

Hormone Disrupting Chemicals

First published in Woopi News in June 2025

Most Australians are unknowingly exposed to endocrine disrupting chemicals (EDCs) in their homes — and the health consequences can be profound.

EDCs are chemicals that interfere with hormone function and are commonly found in plastics, pesticides, furniture, personal care products, cleaning agents, and household dust. Exposure is especially concerning during pregnancy, infancy, and adolescence — critical stages when the body is more sensitive to hormonal changes that can affect development and increase the risk of long-term health issues.

Heating food in plastic containers is a major concern. Once plastic has been heated, it can release EDCs such as BPA and phthalates, which leach into food and drinks — and continue to do so even when the container is no longer heated. These chemicals are linked to reproductive disorders, cancer, thyroid dysfunction, obesity, diabetes, and neurodevelopmental delays.

Tip: Next time you order takeaway food, ask the restaurant if they are willing to put your meals in glass or stainless-steel containers that you provide for them. Our family has often done this with the restaurants in Woopi, and they have always accommodated our request.

Research has linked EDC exposure and rising rates of chronic illness, including male and female infertility, prostate disorders, breast cancer, thyroid disease, and learning and behavioural problems. Importantly, even low doses — previously considered harmless — can have permanent and multigenerational effects.

Did you know? A container labelled “microwave safe” simply means it won’t melt or warp in the microwave — it doesn’t mean your food is protected from harmful chemicals. When plastic is heated, it can still release toxins into your food, even if the container stays intact.

With more than 38,000 industrial chemicals in use in Australia, most untested for long-term safety, reducing your exposure at home is essential.
✔ Avoid plastics for food storage and heating
✔ Choose fragrance-free and non-toxic personal care and cleaning products
✔ Eat organic food
✔ Filter drinking water
✔ Minimise dust using a HEPA vacuum

Our homes should support our health — not silently undermine it.

Improving Sleep Naturally

First published in Woopi News in May 2025

Sleep, along with good nutrition and regular exercise, is one of the three pillars of health. Yet according to a 2018 Parliamentary Inquiry into Sleep Health Awareness in Australia, sleep is often overlooked. The report found that around 40% of Australians experience inadequate sleep—an issue linked to chronic disease, mental health challenges, reduced concentration, higher accident risk, and lost productivity. In fact, in 2016–17 alone, the economic cost of poor sleep in Australia was estimated at a staggering $66.3 billion.

As a Building Biologist, I often see how our home environments can quietly disrupt our sleep. The good news? A few simple, evidence-based adjustments can make a noticeable difference.

1. Reduce EMFs in the Bedroom
Electromagnetic fields (EMFs) from Wi-Fi routers, mobile phones, smart devices (like baby monitors), and electric clocks can interfere with the body’s natural sleep-wake cycles.
Tip: Switch off Wi-Fi overnight, keep phones out of the bedroom (or on airplane mode), and avoid sleeping near power boards, smart meters or electronic devices.

2. Be Screen-Free Before Bed
Blue light from screens suppresses melatonin, the hormone that helps us fall and stay asleep.
Tip: Power down screens at least an hour before bed. Unwind instead with a book, gentle stretching or mindfulness practices.

3. Watch the Caffeine and Stimulants
Caffeine can stay in your system for up to eight hours—and it’s not just in coffee. It’s also found in black, green, oolong and matcha teas, chocolate, energy drinks and some soft drinks.
Tip: Switch to herbal teas, freshly-squeezed juices or water after midday, and steer clear of hidden caffeine sources in the evening.

4. Make Your Bedroom a Sanctuary
A restful bedroom helps cue your body for sleep.
Tip: Choose calming colours, soft lighting, natural fibres, and keep the space tidy and well-ventilated. Avoid synthetic fragrances or harsh cleaning products.

5. Stick to a Routine
Our bodies thrive on routine. Going to bed and waking up at the same time each day helps regulate your internal clock.
Tip: Add a calming ritual—like journaling, reading or a warm shower—to help signal that it’s time to sleep.

Don’t worry about sounding professional. Sound like you. There are over 1.5 billion websites out there, but your story is what’s going to separate this one from the rest. If you read the words back and don’t hear your own voice in your head, that’s a good sign you still have more work to do.

Be clear, be confident and don’t overthink it. The beauty of your story is that it’s going to continue to evolve and your site can evolve with it. Your goal should be to make it feel right for right now. Later will take care of itself. It always does.
