No, definitely do not iron bed linen. There really is no need. If you hang them up straight to dry, they don't crumple. With fitted sheets they stretch out flat anyway.
The same goes for clothing. I only iron summer stuff which you can't get away with not ironing, shirts etc. the rest, if hung out to dry will generally not crease. I may occasionally iron my jeans if they are crumpled, but that's about it. Also I don't have a tumble dryer so have to make sure that clothing is laid flat when drying.
