Thank you for your mindful response :). Maybe hand washing our yoga clothes and towel, and hanging them to dry is the way to go. To think that our practice is all that is important and that we should do whatever it takes to do it, no matter the cost, is something we should think about. Maybe doing some days in normal temperature could save gallons of water (no need to wash towels), besides of the energy cost of heating the rooms. With the El NiƱo phenomenon lots of places in the world are having droughts, and we need to save water. All the best to you all.
