BAck in the day, when people slept with their domestic critters, bundled all winter, and didn't bathe, it may have worked. There were no chemicals other than lye. They live through a hot bath, but that isn't as hot. They boiled clothing and that worked.
Jus' speculatin',
I just looked this up online:
"Will laundering kill head lice?
Washing, soaking, or drying items at a temperature greater than 130°F can kill both head lice and nits. Dry cleaning also kills head lice and nits. Only items that have been in contact with the head of the infested person in the 48 hours before treatment should be considered for cleaning."
I can stay in 140F for quite a while most days. The redline begins at 150F or 160F. We keep the temp in the red area, which goes past 180F. This quote includes eggs, I assume. Each time water is splayed over the rocks and pipes the temperature increases quickly. I can feel the wave of heat.
Sweating is wonderful, we do it regularly. Skin feels better, toxins diminish. A body can drop two pounds of toxins through the skin in a day and it cleanses the system to work optimally. A good brushing or more will wisk the skin, opens it, and massages the lymphatic areas in stimulation. It cleanses the body and if you share with naked friends in prayer, it cleanses the soul. There is a calming relaxed high from it, but sometimes it just spaces people out for an hour or two. Disease, can disappear. It is a gathering in trust and community. Getting dressed seems ridiculous afterward, where we are, so it promotes naturism. A cold day becomes comfortable nude and a hot day feels cool.
