Hey beautiful,
For most of my 20s and 30s, I drank from plastic water bottles every single day. I didn’t think twice. Everyone did.
Then I became a mum — and something shifts. You start reading labels. Researching ingredients. Looking at everything in your kitchen differently.
What I found about microplastics genuinely stopped me in my tracks. And once you know, you can’t un-know it
This week we're covering:
What microplastics actually are and where they’re hiding in your daily routine
What early research suggests they may be doing to women’s bodies
Simple swaps that make a real difference — starting with what you drink from
This week in wellness
Harvard is sounding the alarm on microplastics and women’s health —
Microplastics are showing up in lungs, brains, and even the placenta during pregnancy — and researchers are now linking them to cardiovascular issues and inflammation. One of the most important reads of the year.
Microplastics found in placental tissue — and bottled water may be a key source
Women who regularly drank bottled water showed elevated levels of microplastics in their placental tissue. For mums and mums-to-be especially, this study is a real wake-up call.
The foods and drinks that make microplastic exposure worse — and better —
Bottled beverages and ultraprocessed foods are linked to higher microplastic exposure — while filtered tap water, fibre-rich foods, and stainless steel containers can help limit it at home.
Where Microplastics Are Coming From — And What You Can Actually Do About It
Microplastics are tiny plastic fragments less than 5mm in size. They’re in the air, the water, the soil, the food — and pretty much everywhere scientists look inside the human body, they find them. You can’t avoid them entirely. But you can cut your daily exposure significantly once you know where the biggest sources are.
🔹 Plastic Water Bottles
A single litre of bottled water can contain up to 240,000 nanoplastic particles — so small they can enter your bloodstream directly. Switching to stainless steel or glass is one of the highest-impact changes you can make.
🔹 Heat Makes It So Much Worse
Warm or hot drinks in plastic containers dramatically increase how much plastic leaches into your drink. Your morning tea in a takeaway cup. Coffee with a plastic lid. Most people swap the bottle — and forget the straw. That’s where a lot of the leaching actually happens.
🔹 Your Hormones
Many plastics contain chemicals called endocrine disruptors — BPA and phthalates — that interfere with your hormone signalling. Research links microplastic exposure to cycle disruption, fertility concerns, and inflammation.
🔹 Your Gut
In the gut, microplastics may inflame intestinal tissue, damage the gut barrier, and alter the gut microbiome — affecting your digestion, immunity, and mood. (Sound familiar from last week?)
🔹 Your Reproductive Health
New research from Harvard found microplastics in placental tissue — and women who regularly drank bottled water had higher levels. For mums and mums-to-be, this is especially important to know.
“ The use of plastics is likely detrimental from an individual and societal perspective.” — Dr. Sanjay Rajagopalan, Case Western Reserve University”
Takeaway: You can’t control what’s in the air. But you can control what you drink from — and that matters.
🥤 Sip of the Week: Elderberry & Echinacea Iced Tea
No plastic bottles needed. Make this at home, pour it into a stainless steel tumbler, done.
Ingredients:
500ml filtered water — your plastic-free base
1 elderberry tea bag — antioxidant-rich, anti-inflammatory, supports immune health
1 echinacea tea bag — traditionally used to support immune defence, especially good for women
Juice of half a lemon — vitamin C, brightens the flavour
1 tsp raw honey — natural sweetener, prebiotic
Instructions:
Steep both tea bags in hot water for 8–10 minutes — the longer, the deeper the colour and flavour. Remove bags, let cool, add lemon juice and honey. Pour over ice into your tumbler.
Perfect for: afternoons when you’d normally reach for something fizzy — immune-supportive, antioxidant-rich, and completely plastic-free
🧠This Week’s Quiz
Most women who take this get a result they weren’t expecting. Just saying.
My Notebook
I drank from plastic water bottles throughout my entire 20s and 30s without a second thought. Then I became a mum — and something shifts.
You start reading everything differently. What I discovered about microplastics unsettled me — not with guilt, but with a kind of clarity that makes you want to act.
I’m so grateful to the mums online making this a louder conversation. Quietly, it was one of the things that led me to build BriteLune.
🔍 Quick Rituals
✅ Try this today: Swap one plastic bottle or cup for stainless steel or glass — your water bottle, morning coffee cup, or smoothie.
✅ Try this week: Check your kitchen for plastic containers you regularly heat food or drinks in — glass or stainless steel is an easy switch.
🚫 Skip this: Drinking hot drinks through a plastic straw — heat is when plastic leaches most, and the straw is the part most people forget about.
