Sanding while pregnant is generally considered safe, but it should be done with caution. It is important to wear a dust mask and eye protection when sanding, as inhaling or coming in contact with the fine particles of wood can cause health risks. While there isn't an abundance of research on the effects of sanding during pregnancy, some studies suggest that exposure to sawdust and other airborne particles may increase your risk for preterm labor or miscarriage. Therefore, if you are pregnant and must do any type of sanding work, it's best to limit your exposure as much as possible by wearing protective gear such as gloves and goggles and ensuring adequate ventilation.
