タイトルまたは説明

Quartz possesses a unique health-improving ability: when heated and then cooled with water abruptly it emits monatomic oxygen and as a result the air in the steam room is saturated with ozone. Ozone enriches blood with oxygen, improves your state in general and stimulates brain activities.
Abrupt changes of temperature cause mechanical deformations which make quartz crystals generate electromagnetic oscillations. It is called piezoelectric effect. These oscillations interact with electromagnetic fields of a human body, correct and restore its bioenergy system.
