silk saves my energy

I have been reading about the benefits of silk bedding, and in addition to the health aspects, I found one that appeals to my lazy side. Silk duvets require less cleaning than a conventional duvet. This is because the natural silk is an inhospitable environment for dust mites and other bacteria, which means they are inherently cleaner. And hanging the duvet out in the sun for a few hours a couple of times a year will give it sufficient airing as well as producing a fuller and softer feeling. Not only to I save energy (mine included), but I also save water.
