Because of this need for the comfort of humidity, we usually do our laundry before we go to bed and drape it over any available space in our room. It's not very attractive but it saves energy, we sleep comfortably, and it is dry and ready to put away when we wake up. Sink water is conserved by not letting water run while brushing teeth or washing up. It is recommended that toilets not be flushed after every use. Due to extremely low humidity and high altitude, personal dehydration is a constant concern.
Water conservation is practiced except in the case of personal water consumption.
One of the first symptoms I experience when not drinking enough water is a headache. Especially during the first several weeks after our arrival, I frequently woke up during the night with a dry nose and mouth in spite of more than a gallon of water the 2 humidifiers we brought with us put into the air of our small room. I still keep my water bottle propped in the corner of my bed when I sleep so I can easily take sips of water during the night. Due to the extremely dry air, bloody noses are not uncommon. Before deploying to the ice, everyone was issued a plastic quart-sized water bottle.
