Bake some bed

The method pictured above only works if your bed happens to be a futon. This soft, bendable bedding is lighter and easier to maneuver than a western style mattress. It rests right on the floor of your house, provided that the floor in question is lined with tatami mats rather than wood. I have been told that the difference between the two is significant since wood is uncomfortably hard and its density prohibits air flow. Though the woven texture of the tatami does allow your futon to breathe, it will not eliminate the problem of sweat and dead skin cell accumulation over time. So, the Japanese recommend throwing your bed out on the balcony every day, or at least whenever the sun is shining. Heat from the heavens basically disinfects the fabric, drying it and discouraging the build up of mold and mildew. Merely hanging up your bed is not sufficient, however, and you are advised to give it a good beating with a special stick. I believe the preferred material is bamboo, but we have seen a few resourceful people using hangers and broomsticks. Bonus: while your bed is baking in the sun, the tatami mats get a break and are free to be vacuumed or sprayed if necessary.
