Are Bed Sheets Toxic
Polyester-cotton bed sheets and “no-iron” cotton bed sheets are treated with a formaldehyde-based permanent-press finish to keep them wrinkle free. However, the formaldehyde resin continues to release formaldehyde fumes for the life of the fabric, since it becomes a permanent and irremovable part of the fiber. Although washing and wearing can diminish formaldehyde levels, the residues remain as long as the fabric wrinkle free. Unfortunately, formaldehyde exposure can cause headaches, skin rashes, respiratory problems, fatigue, and insomnia. Therefore, it is recommended to choose sheets made from cotton flannel, untreated 100-percent cotton, or knit cotton jersey.
