Putting the mattress outside when it is -30º or colder will also do in the dust mites within half an hour ...ORIGINAL: RangerJoe

Explain this concept of changing the bed linens.
When (not if) you remove the sheets and pillow cases from the bed to wash them, then you put another set on. Although it would be actually better if you left it bare to air out. In fact, it would be good once a year to set the mattress and even the box spring outside during the day so the sun can clean it with the UV rays plus airing it out. Putting it outside can end up killing any mold/mildew on it - even if you do not notice it.
The little dust mites living on the bed feed off dead skin cells and use the human sweat as a source of water. Those dust mites can aggravate asthma.
I hope that helps.
Plus, if it takes 5 minutes a day to rearrange the bedding (Mom: "Make your bed!) so that the bedding looks nice, if you do not do that you could save 5 minutes a day. In 6 days that is half an hour. Over a year, that is over one full day.
Does it get that cold in San Diego?
Winnipeg, yes it does even without any windchill. Keep a cooler or two in your trunk as a free extra freezer . . . [:D]
