You spend 1/3 of your Life in bed, which is why it is important to keep your bed very clean. At night we shed skin cells, which serves as food for dust mites. Oh Geez! We also leave sweat, oils and bodily fluids on the linens. For some people, they eat in bed and leave food crumbs. Okay, now that's just gross! Pick a day of the week to wash your sheets and pillow cases. Weekly is perfect! Pick another time to wash your blankets and comforters.
