>>40752836 (OP)I saw a post on Facebook (yeah yeah I know, shut up) that stated the vibrational frequency of polyester is lower than the vibrational frequency of cotton. And they recommended changing out any polyester mixed sheets from your bed, linen and cotton in order to preserve the mind better while resting.
Not sure if there's anything to it but there is strangely polyester in fucking everything now, and it seems to be replacing most materials. Who knows, maybe it's legit
