Why would CRYSTALS help us sleep?

There's a science behind crystals, and why they can help our bodies get into a more balanced "rhythm." If you haven't heard of Piezoelectricity, here's the definition:

Piezoelectricity is the ability of the material to develop electric charge in response to the applied mechanical stress (direct piezoelectric effect) and vice-versa (inverse piezoelectric effect). In bone, piezoelectricity was first observed by Yasuda.
