Most polyester clothing is loaded with endocrine-disrupting and carcinogenic chemicals like BPA, PFOA, PFCs, formaldehydes, and flame retardants.
Not exactly something you want sitting on your skin all day.
Now think about where those clothes sit.
Tight leggings. Sports bras. Underwear. Gym shorts.
Add sweat and heat, and those chemicals sit directly against your skin while the fabric sheds tiny plastic fibers into the environment and food chain. Research shows this can lead to inflammation, oxidative stress, and long-term health issues.
There’s even some strange fertility research around polyester.
One study found about 75% of female dogs wearing polyester garments became infertile due to hormone disruption.
Other studies suggest tight polyester underwear can drastically reduce sperm production in men.
In other words, polyester shorts might double as birth control.
But here’s the part most people never hear about.
Your clothes don’t just sit on your body, they carry a vibration too.
The human body resonates at about 100 mHz, which cotton matches almost perfectly.
While polyester sits down around 0-15... about the same frequency measured in a dying body.
