According to Kathy Turley from Home Clean Heroes, your bed is like the VIP section for dust mites, dead skin, and bacteria — all living their best lives. Ohio State University even found that a mattress can host up to a million dust mites at any time. So, while washing your sheets might make you feel better, the microscopic party under the covers is far from over!
