Mold in bedroom settings is particularly problematic because, while mold in any room of the home presents a health hazard, people often spend more time in their bedrooms than in any other room. You might spend eight hours in your bedroom at night, every night, while you might only spend an hour or so in the bathroom, another hour or so in the kitchen, and just a few hours in the living room. That means your exposure to mold may be significantly greater if there is mold in your bedroom than in some other room.
