I use the net scrubber VERY gently. It does a better job than a washcloth of spreading the body wash, doesn't scrub any harder, and it does a great job on my heels, keeps them smooth and soft. It also rinses cleaner than a washcloth, which would have to be changed daily to keep from growing mold. Part of the scrub - Rx'd by allergist - is to keep hair follicles open. I have keratosis pilaris. That's rash-looking little pimple-like bumps on fronts of thighs, backs of upper arms, just a few on rear. Half the people have it, think it's pimples, which it's not! Picking just causes infections. Hereditary.
Yes, shots for dust, probably is mainly for dust mites. Auto-immune to roaches?
No shorts or anything else constricting around waist at night. Nothing at all in summer. T-shirt (or short sleeve all cotten nightgown) is only for winter.
The double rinse is for the sheets too! It's more important than anything else! When I'm in the hospital I have to make sure to get all double rinsed gowns, towels and sheets. Hospital laundry detergent is horrible! Itch scratch, itch scratch, itch scratch...!
I'm not sure I'd want to use bamboo. I have good luck with cotten - undies, clothes, socks ... Some people are allergic to cotton, have to use only synthetics. You can try using only one or the other for a few weeks, then switch.
