Your bedroom should be a sanctuary — the one tidy, clean, and serene place you can go to feel relaxed. Piles of laundry, overstuffed closets, and a layer of dust won’t contribute to your peace of mind. What’s more, making a clean bedroom a priority can help you avoid dust mites, a major cause of year-round allergies. While these microscopic creatures live in warm, dark places, such as pillows and mattresses, routine-cleaning measures can help minimize their presence. The more effort you put into cleaning your bedroom, the better you’ll sleep.
