When you are in a same posture for a long time, the "SOUBOUKIN" covering the shoulders gets tense and causes muscle fatigue.

Tense muscles contact repeatedly and become tight. This compresses blood vessels, and the circulation of blood becomes sluggish. The blood flow rate then descends, and muscles become oxygen deprived.

Then Algesic substances such as Lactic Acid are developed and start to irritate nerves in the muscles. This results in stiffness in the shoulders. When you ignore these symptoms, additional muscles become tense and you fall into a vicious cycle of stiffness.

Extensive magnetic effects help soothe the contraction of muscles, stimulating blood flow and getting rid of algesic substances. Colantotte helps stimulate body-wide blood flow by wide-ranging effects rather than a one-point-effect.
