[Linear polarized light irradiation around the stellate ganglion area increases skin temperature and blood flow].

We evaluated the effect of linear polarized light irradiation with a SUPER LIZER around the stellate ganglion area on skin temperature and blood flow in healthy adult volunteers. We carried out two experiments (study I and study II). In study I, we investigated one-sided irradiation around the stellate ganglion area or posterior neck on the skin temperature of the bilateral nasus externi and earlobes. In study II, we investigated one-sided irradiation around the stellate ganglion area or posterior neck on the skin temperatures of both hands and skin blood flow on the irradiated side. In study I, irradiation around the stellate ganglion area increased skin temperature on the irradiated sides of the nasus externi (wings of the nose), and in study II, skin temperature and blood flow were increased on the irradiated side of the hands. These results suggest that linear polarized light irradiation with a SUPER LIZER around the stellate ganglion area would be useful and beneficial in clinical therapy.
