Why Your Pillow Might Be Sabotaging Your Sleep (And How to Fix It)

Sleep is honestly one of my favorite things. I don’t get enough of it most nights, but I make it a habit to prioritize my sleep as someone who pays attention to my health and my wellness.

Sleep doesn’t just support your immune system — it’s a fast track to restoring every system in the body. Harvard studies on sleep tell us that the cost of poor sleep is much greater than many people think and it eventually leads to increased risk of chronic disease.

Pillows are just one piece of the sleep puzzle.

On October 5th, I’m hosting a live 60-minute Healthy Bedroom Audit where we’ll evaluate your mattress, wall placement, air exchange, and EMFs together.

It’s important to have healthy habits around sleep, but it’s just as crucial to have a healthy environment around your body while you sleep. The truth is, we spend 7-9 hours every night in our bedrooms, and the items closest to us are going to have the biggest impact on our health.

Think for a moment about everything that surrounds you all night long — pillows, blankets, sheets, mattress, electronics. When these items contain chemicals and toxins, our sleep becomes disrupted. Our body and brain read chemicals as a stressor, which triggers the release of cortisol — and cortisol inhibits sleep and disrupts otherwise-healthy sleep patterns.

A mattress can be a great swap, but it’s often one of the last changes people make because of how costly it is. I personally think the best swap for any bedroom is a toxin-free pillow.

Think about the proximity of a pillow to your face, your breathing zone, your skin. It has the potential to be a toxin pathway in multiple ways. But on the flip side, it can actually support your health and wellness during some of the most crucial hours your body spends healing and restoring.

The Science of the Sleep Environment

Your immediate sleep space deserves close attention because what surrounds you at night directly impacts your air quality.

A landmark exposure study from the University of Texas at Austin found that sleeping on conventional polyurethane foam creates an elevated chemical micro-environment right in your breathing zone. As your body rests against the pillow, heat and humidity speed up the off-gassing of volatile organic compounds, meaning you inhale higher concentrations of these chemicals right where you breathe.

At the same time, research published in Environmental Science and Pollution Research shows that synthetic, petroleum-based bedding constantly sheds airborne microfibers into the air of closed rooms.

During slow-wave sleep, your brain depends on the glymphatic system to clear out metabolic waste and cellular debris. By choosing clean, natural materials for your pillow, you remove that unnecessary chemical and particulate burden from your airways — giving your immune system and brain the uninterrupted recovery time they need.

Greenwashed Pillows

First, let’s talk about greenwashing. If you’re not familiar with the term, it basically means products using words like “green,” “organic,” or “natural” on their packaging when it’s not entirely true. A pillow may say organic, but that might only refer to the casing. It may say natural, but that might only refer to part of the inside — not the pillow as a whole.

Grabbing something just because it’s made to look like a healthy choice, or because it says “eco-friendly,” isn’t the best way to shop. A lot of these terms aren’t regulated by the FTC, which means anyone can put whatever they want on packaging.

Another place we see a lot of greenwashing with pillows is when brands only address one part of the product. Many advertise “organic” pillows while only certifying the removable slip cover — leaving the inside stuffed with synthetic fibers, blended fills, or chemically treated batting.

Instead, look for third-party certifications or do a little research before you buy. That way, you can avoid becoming a victim of the greenwashing epidemic.

What to Look For In Healthy Pillows

Organic Fibers: Cotton, wool, buckwheat, natural latex, and kapok are all great materials to look for in a pillow.

Cotton: Naturally breathable and naturally resistant to bacteria. 100% organic cotton is grown and harvested without chemicals or pesticides — great for anyone who wants a soft pillow.
Wool: A natural insulator that’s also fire- and water-resistant, and it naturally combats mold and mildew. Bonus: dust mites don’t care for it.
Buckwheat: Made from buckwheat hulls, this is a great option for allergy sufferers. The way the hulls settle makes for a really breathable, cool, dry pillow.
Natural Latex: Made from rubber trees, natural latex holds its form well and has a bit of bounce to it. It’s also 100% biodegradable.
Kapok: Derived from a tropical tree, this soft fiber — sometimes called “silk cotton” — makes a great alternative to down or polyester fill.

Third-Party Certifications: These are your best friends when you don’t have time to research every brand yourself.

GOTS (Global Organic Textile Standard): One of the better certifications to look for — it ensures the materials and manufacturing process are all in order.
GOLS (Global Organic Latex Standard): The best certification to look for if you’re buying a shredded latex pillow.
Oeko-Tex Standard: Tests the materials used in a product for hazardous chemicals at various stages of production, to ensure the health and safety of the finished product.
GreenGuard: Checks for VOCs, formaldehyde, and other chemicals in the product. GreenGuard Gold is even better, with stricter limits on the chemicals allowed in the finished product.
MadeSafe: Often the hardest certification to earn — it involves rigorous screening for known toxins, carcinogens, and endocrine disruptors.

Breathability: A breathable pillow won’t hold onto excess moisture or trap heat. This keeps your pillow feeling fresh and also helps prevent dust mites and mold spores from making themselves at home in your sleeping area.

What Pillow Materials & Additives to Avoid

Flame Retardants: Flame retardants (PBDEs) are commonly found in the polyurethane foam used in pillows. This chemical isn’t just unnecessary in this day and age — it’s been linked to real problems from a full night’s exposure, including issues with thyroid function and brain development in children. (STUDY)

Formaldehyde: Used as a preservative and to keep fabrics smooth and wrinkle-free, formaldehyde is added to many foam pillows and cushions. The problem? It’s a known human carcinogen — and we’re spending long stretches of time in close contact with it every night. (STUDY)

Deodorizers & Scents: Honestly, if it’s not an organic or natural scent, it’s probably worth avoiding. Deodorizers and added scents are usually there to mask a chemical smell from other toxic components. Opt for something unscented, or a product that claims to prevent odor rather than cover it up.

VOCs: Volatile organic compounds off-gas for the entire lifetime of the item they’re in, and they off-gas at a much higher rate in warm, humid environments compared to cool, dry ones. Think about your bed for a second — that’s exactly the kind of environment that encourages high rates of off-gassing.

Pesticides: Any material that’s farmed or grown has the potential for pesticide use. Residue can remain on natural materials — especially cotton. This post can help you understand what pesticides are actually doing to your body.

Polyester: Made from plastic toxins and petroleum, polyester is toxic on its own — and it off-gasses harmful chemicals as it breaks down over time, too.
