gentlehoney, I don't sterilise any clothes. I just machine wash everything at 30-40C. (Never hotter than 40C.)
I might soak/hand wash if there was something really horrible eg dog poo/vomit. (Or a stubborn stain.) But this is rare.
I also only wash things when they are properly dirty/have been used more than once. (Sometimes used/worn over weeks/months eg jeans.). And there have been no obvious negative health consequences for me (or my family) ... so far!
I don't bath/shower daily either & I think that I don't smell too bad. (Tho I realise that I don't smell sweetly perfumed either!)
There's obviously a fine line between becoming a mouldy old tramp and being carried along with the current obsessive levels of personal hygiene, & I do worry about drifting into the tramp category, mainly in reaction to all the ppl who waste water and energy excessively! (Maybe I shd go live/hide in the countryside, where no-one will notice/smell me?)
Deep down, I do have a fear that we, (eg in the UK), will one day run out of clean water and/or the fuel to process 'dirty' water into 'clean' water, as we are a growing population who have come to expect/demand (cheap) unlimited clean water and the energy to heat it, without any care for the environmental cost.
If we lived in a small group on a desert island with limited fresh water, would we be happy to see it being used to shower and wash clothes all the time? (Or would we want to save it, mostly for essential drinking & cooking?)
We all need water to drink, cook with and to wash ourselves/our homes, but most ppl I know are VERY wasteful with it.
How did we possibly manage to survive when we had to all bathe in the same river or pond and carry water to our homes for cooking/drinking. And has anyone had to go a week with no water in their town ... as in none at all? (I have. But we were able to buy some bottled water at least ... just for drinking.) After that sort of a wake-up experience, you find that you can survive on a lot less water. (And you tend to stop caring about washing towels daily & whether your hair is a tad greasy!)
I love a deep/hot bath as much as the next person, but wars have been fought over access to clean water, and probably will be again one day. And I wonder what will priority we will assign to "personal hygiene" for the average person then?
I know I am probably being VERY unreasonable to use this thread as an opportunity to sound off, but I also feel someone has to try to stop the current "uber-hygiene" madness, before we forget how to live 'normally' and start to learn to use clean water more sparingly!
