Many people underestimate how strongly their sleeping environment affects their health. A bed should be a safe and restorative place, yet a surprisingly common habit—sleeping on dirty sheets, mattresses, or pillows—can turn it into a breeding ground for unwanted insects, including cockroaches. While these pests are often associated with kitchens or storage areas, they can be drawn to unclean sleeping spaces and may come into direct contact with human skin. That contact can contribute to several dermatological issues, especially for individuals with sensitive skin.
