+1& @Kvothe There are people who I know suffering arthritic like symptoms when wearing fibers which encourage static buildup, especially in dry weather. Even TCM warns against wool even though it's a natural fiber because of its ability to mess with the bodies more intricate communication systems/ flow of chi.
maybe someone who is completely sedentary who never sweats would be "fine" wearing this crap but those who are sweaty and actually do stuff are at risk. Sweat is warm, salty and the skin acidic perfect condition to leach crap from plastic clothes. I don't know if Dr. Peat has actually said that 1 and if he has he must not realize how much of everyone's stuff is plastic from carpet, jackets, shoes, socks, underwear, couches, blankets, bedding, pillows etc and like mentioned above people then wash all this plastic and dry it... getting the plastic in the air of their home and municipal water supply.
Imo it's definitely a concern
