You're wearing toxic clothing 24/7
Sure, we eat organic apples, home-grown rosemary and GMO free corn. There is a lot of awareness around conventional produce and pesticides. However, not so many people care about what they put on their skin (the largest of our organs!). Our clothing is full of chemicals and toxins, which are being absorbed by our skin directly into our body. We're talking here about something that is on our skin basically 24/7. And when we sweat, we absorb even more of the chemical residues in the fabric.
Let's start with conventionally grown cotton:
Everyone likes cotton clothing. Cotton fiber is durable, absorbant and breathable. But cotton is also a very water- and pesticide-intensive crop, which is mostly grown in monoculture. Monoculture causes soil degradation. And pesticides not only pollute rivers and groundwater, but also transfer from the cotton fiber onto our body.
Synthetic fiber is not a whole lot better when it comes to toxins:
Polyester traps body heat and encourages chemical absorption. Acrylic fabrics are believed to cause cancer. Anything "wrinkle-free" and "shrinkage-free" releases formaldehyde, which is linked to lung cancer. Water-repellent clothes use basically teflon - which, again, is linked to cancer -. The chemicals are "baked" into the fabric to make it resistant to wrinkling and water and they are being released onto our skin.
Oh, and guess what, not only the fabric itself is full of chemicals, the dyes also are! Blue fabric dye is especially toxic.
Let's take a moment and look at distressed denim jeans.
Distressed denim is very trendy right now. This "worn" effect is usually achieved by sandblasting techniques: chemicals (great, more chemicals!) and mineral dust are sprayed against jeans. Without proper protection, workers are exposed to highly harmful particles that cause severe lung problems. And you are exposed to yet another layer of chemicals.
I'm not trying to lobby for "all organic" here. (Pesticides can sometimes also be found in organic cotton fabric.) But still, you are definitely a lot safer if you choose clothing that is made from 100% organic cotton, silk, linen, hemp, or tencel (a natural cellulose).
Again, I'd like emphasize, your skin is the largest organ in your body, be extra careful with what you cover it.
