A bed net is a protective mesh fabric that is typically used to cover a bed, providing a barrier against insects, particularly mosquitoes. These nets are often treated with insecticides to enhance their effectiveness in preventing bites and the transmission of diseases such as malaria and dengue fever. Bed nets are commonly used in regions where these diseases are prevalent. Bed nets come in various shapes and sizes, including rectangular and circular designs. They can be hung from the ceiling or attached to the bed frame. Using a bed net is a simple yet effective way to improve sleep quality and reduce the risk of insect-borne illnesses, especially in tropical and subtropical areas.
