Why Your Clothes Might Be Making You Sick
Most people don't realize that what we wear directly affects our health. The fashion industry has normalized synthetic fabrics like polyester, nylon, and acrylic—but these materials come with hidden health costs that go far beyond discomfort.
When you wear synthetic clothing, you're essentially wrapping your body in plastic. And just like plastic water bottles leach chemicals into your drink, synthetic fabrics release microplastics and hormone-disrupting chemicals directly onto your skin.
The Hidden Dangers of Synthetic Fabrics
Hormone Disruption
Polyester and other synthetic materials contain endocrine-disrupting chemicals (EDCs) that interfere with your body's natural hormone production. Studies have shown that prolonged exposure to these chemicals can affect:
- Thyroid function
- Fertility and reproductive health
- Metabolic processes
- Mood regulation
Women who wear synthetic underwear and activewear daily are particularly at risk, as these garments sit directly against sensitive skin for extended periods.
Microplastic Absorption
Every time you wear synthetic clothing, tiny plastic fibers break off and are absorbed through your skin. Research has found microplastics in human blood, lungs, and even placentas—and a significant source is the clothing we wear daily.
These microplastics accumulate in your body over time and can trigger:
- Inflammation
- Weakened immune response
- Cellular damage
- Unknown long-term health effects still being studied
Skin Irritation and Allergies
Synthetic fabrics trap heat and moisture against your skin, creating the perfect environment for:
- Bacterial growth
- Fungal infections
- Eczema flare-ups
- Contact dermatitis
- Body odor
If you've ever noticed that you smell worse in polyester gym clothes than cotton ones, this is why.
The Natural Fibre Solution
Merino Wool
Unlike synthetic fabrics, merino wool is:
- Naturally breathable (regulates body temperature)
- Moisture-wicking without trapping bacteria
- Odour-resistant (you can wear it multiple times between washes)
- Biodegradable (returns to earth instead of sitting in landfills for 200+ years)
- Free from hormone-disrupting chemicals
At Sashū, our merino wool sweaters are designed for everyday wear—not just outdoor adventures. They're soft enough for sensitive skin and stylish enough for work, dates, or weekend brunches.
Cashmere
Cashmere offers the same health benefits as merino wool, with added luxury:
- Hypoallergenic (perfect for sensitive skin)
- Thermoregulating (keeps you warm without overheating)
- Incredibly soft and comfortable
- Long-lasting when cared for properly
Our cashmere pieces are investment items designed to last 10-20 years—the opposite of fast fashion's disposable approach.
Cotton
For warmer weather or layering, cotton provides:
- Breathability
- Softness
- Durability
Our cotton pieces are a great swap to wear on those casual days when you want natural fabric against your skin.
Making the Switch: Start Small
You don't need to replace your entire wardrobe overnight. Start with the pieces that sit closest to your skin:
- Underwear and base layers - These have the most direct contact with your body
- Sleepwear - You spend 8 hours a night in these clothes
- Everyday essentials - Sweaters, t-shirts, and pieces you wear frequently
The Long-Term Benefits
When you switch to natural fiber clothing, you'll notice:
Immediate Changes:
- Better temperature regulation (no more sweating in synthetic layers)
- Reduced body odor
- More comfortable skin (less irritation and itching)
Long-Term Health Benefits:
- Reduced exposure to hormone-disrupting chemicals
- Lower microplastic accumulation in your body
- Improved overall wellbeing
