Conventional Yoga Mats Contain Toxic Chemicals That Can Be Problematic of to the Environment & Us
When you pick up a yoga mat, I betcha you didn’t think that it would come with s side of endocrine disruption, but that’s exactly what is happening. Most of the yoga mats produced are created with materials that have the ability to off-gas, disrupt hormones, or are problematic to the environment.
- PVC (polyvinyl chloride)
- PER (Polymer Environmental Resin)
- PU (Polyurethane)
- NBR Foam (Acrylonitrile Butadiene Rubber)
- TPE (thermoplastic elastomer)
PVC (Polyvinyl chloride) Yoga Mats
Most yoga mats you will find are made of polyvinyl chloride or “vinyl” which are #3 plastic resin code. It’s incredibly toxic to humans and the environment. But when it comes to practicing yoga, exposure comes through inhalation and skin contact.
Vinyl is carcinogenic when inhaled, but it’s also incredibly toxic to the environment when it’s manufactured because it produces dioxins as a byproduct. Dioxins are classified as a human carcinogen by the Environmental Protection Agency (EPA) listed as priority pollutants. They are also persistent in the environment and do not break down easily and they bioaccumulate in our bodies inside fat deposits.
Plasticizers are also added to PVC to make it soft and flexible for a yoga mat. Phthalates are an endocrine-disrupting chemical with the ability to disrupt hormones. One of the effects phthalates are linked to is weight gain, which is the opposite of what most people want when they are practicing yoga. Phthalates are also linked to birth defects, infertility, asthma, neurodevelopmental problems in infants and cancer.
PER (Polymer Environmental Resin) Yoga Mats
PER is produced from PVC and other materials, however, the extra processing steps make it cleaner than PVC and less toxic to humans.
To create PER, you first make PVC powder, then add a potentially toxic filling agent, light stabilizer and fireproof agent. Once combined, it turns into a cream-like finished product, put into a mold with a hydraulic press and then it’s baked at 170°C to become a usable polymer.
PER has less harmful emissions than PVC and is recyclable. The carcinogenic effects of PER are also minimized because it doesn’t require phthalates to give it a soft and rubbery texture.
This is not a best solution, but a better one from an environmental perspective.
PU (Polyurethane) Foam Yoga Mats
The last ‘chemical’ used for yoga mats is PU or polyurethane. It is considered “non-toxic” by the Feds, but that doesn’t mean the science demonstrates that. In fact, the science behind polyurethane says it offgasses over time, but can’t be recycled and is not biodegradable.
Polyurethane is created when methylene diphenyl diisocyanate (MDI) and toluene diisocyanate (TDI) react with polyols. TDI is suspected to be carcinogenic, is classified as very toxic, and is a known respiratory and skin irritant.
But the biggest problem with polyurethane foam is its high flammability, and because of this fire retardants are typically added. Fire retardants are horribly toxic, so if they used in your yoga mat, you will be exposed to them over time.
TPE (Thermoplastic Elastomer)
Thermoplastic Elastomer (TPE) is popular because it’s anti-microbial and easy to clean. But it’s controversial because it’s a mixture of rubber and plastic. However, TPE is free of bisphenols like BPA or BPS, phthalates, lead, PVC (vinyl), etc.
Thermoplastic elastomers generally soften and melt at elevated temperatures and lose their rubbery behavior over time meaning they have “poor chemical and heat resistance.” Although this material is better than vinyl, it’s not the best material you can use because over time it will break down. Therefore, it wouldn’t be advisable to ever leave out in the sun or bring to a yoga class that has high temperatures.
They are also not easily biodegradable. We don’t recommend this material as best, but because it doesn’t off-gas, it’s better.
NBR Foam or Acrylonitrile Butadiene Rubber & Recycled Tree Rubber
NBR foam is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. They are also referred to as Perbunan, Nipol, Krynac, Neoprene and Europrene.
Concerns with synthetic rubber are that it may contain PAHs (Polycyclic Aromatic Hydrocarbons) and heavy metals, which are incredibly toxic.
When it’s natural recycled rubber, it’s held together with an unknown synthetic chemical that is a low-VOC binder.
This selection is a better option, but not best, however, we love natural rubber without synthetics.
Safe Materials for Yoga Mats
Cork Yoga Mats
Cork is a natural, eco-friendly material that is very popular and easy to find. Its naturally antimicrobial so synthetic chemicals are not needed to treat the surface of the yoga mat. This also means it won’t get moldy or smelly, even if you sweat a great deal. It’s also naturally slip-proof and very durable, so it can be used for hot yoga as well.
Advantages of Cork
- Excellent grip & slip-free
- Naturally repels static
- Easy to clean and maintain
- Can be used in hot yoga
Disadvantages of Cork
- Weighs more than other mats
- Not very much cushion, so not comfortable for some people
- Typically expensive
Natural Rubber or Recycled Virgin Rubber Yoga Mat
This is natural rubber, not synthetic rubber that we were talking about above. This rubber is collected from rubber trees, which are renewable and eco-friendly. This rubber is naturally soft and has lots of other advantages.
Advantages of Natural Rubber
- Eco-friendly & renewable
- Very good cushioning so comfortable
- Easy to clean
- Great grip & slip-free
Disadvantages of Natural Rubber
- Allergy warning: not suitable for people with latex allergy.
- Heavy materials
- Must take extra time to dry when it gets wet
- Typically expensive
Jute Yoga Mats
Jute is a rough fiber that is used in a wide range of textiles including hessian sacks, floor covering & rope. Jute comes from the plants Corchorus olitorius and Corchorus capsularis found in India. It’s very coarse and rough, so sometimes brands combine it with PER (Polymer Environmental Resin) to give it cushioning and grip. This is not always the case though, sometimes it’s just Jute. Jute also has a very hip & rustic look.
Advantages of Jute
- Naturally anti-microbial
- Naturally anti-static
- Free from allergens like Latex
- Strong fibers
- When combined with PER it has a great grip
Disadvantages of Jute
- Can be scratchy and rough if not combined with PER (or similar)
- Not easy to clean
Featured Yoga Mat: Brentwood Home Organic Non-Slip Yoga Mat
According to Brentwood Home, this is one of the world’s only GOTS® certified organic yoga mats. Made from 100% organic certified cotton with a non-slip base of 100% natural latex for grip. 5mm thick. Super comfy, absorbent, foldable, sustainable, washable, non-toxic, and biodegradable. Also great for hot yoga, the tall yogi, and the traveler. It comes in sage green, midnight navy, pink rose water, gray all day, ocean blue, or smokey blush.
The fabric is woven so the top of the mat is textured and absorptive, wicking away moisture. That means you won’t slip or have to wipe down the mat — especially essential when it comes to hot yoga. We also use natural latex, made from real rubber trees, for the anti-skid bottom. It’s the ideal thickness and weight to ensure stability for styles of yoga with more active poses or balanced, focused poses. And it’s thick enough to be comfortable for forearm and kneeling poses and for yogis with tender knees or achy joints.
