10 Tips for sleeping on a bed of ice
1) Don’t shower just before you go to sleep, because moisture on your body can freeze.
2) Change into dry socks before you sleep; warm, moist skin will give you cold feet.
3) Make sure that you have selected a sleeping bag with a zipper that works; we guarantee
it won’t be fun to fumble about with the zipper in your private igloo.
4) Make sure that the sleeping bag is long enough; you won’t want to have your
entire head exposed.
5) Don’t forget to wiggle into the shroud-like inner-bag the Icehotel provides, which goes
inside your regular sleeping bag; you’ll love it.
6) Pull the zipper tightly shut so that only your nose is exposed, you can even pull the shroud
up over the nose if you want.
7) Don’t keep your entire head inside the bag, even if
sorely tempted; remember, condensation?
8) Wear long johns and a t-shirt to bed;
morning clothes can be kept warm under your
sleeping bag; the felt liners of boots go inside the bag.
9) Above all, don’t share your ice-bed with someone
who snores
10) If you have to sleep beside a snorer because of
marriage or bad luck, have a phone or iPod equipped with
soothing music close at hand, to drown out the sound.
