Microbe inactivation processing method and cell activation processing method

A microbe inactivation processing method comprising:

• a step of applying light emitted from a light source through an optical filter onto a human body, with the light source configured to emit the light having a wavelength within a wavelength range of 190 nm to 237 nm, in order to perform inactivation processing of a target microbe in the human body with an energy of 300 mJ/cm2 to 1000 mJ/cm2, wherein
• when the light emitted from the light source is incident on the optical filter at an incident angle of 0°, the optical filter transmits at least a part of ultraviolet light having a wavelength within a range of not lower than 190 nm and not more than 230 nm, and transmits at least a part of ultraviolet light having a wavelength within a range of more than 230 nm and not more than 237 nm, and the optical filter blocks transmission of ultraviolet light having a wavelength within wavelength ranges of UV-B and UV-C excluding a wavelength range of not lower than 190 nm and not more than 237 nm.

A cell activation processing method comprising:

• a step of applying light emitted from a first light source through an optical filter onto a surface of a human body or inside of a human body, and applying light emitted from a second light source onto the surface of the human body or inside of the human body, with the first light source configured to emit the light having a wavelength within a wavelength range of 190 nm to 237 nm inside of the human body with an energy of 300 mJ/cm2 to 1000 mJ/cm2, and the second light source configured to emit the light having a wavelength in an infrared range, in order to perform activation processing of cells in a light irradiation area, wherein
• when the light emitted from the first light source is incident on the optical filter at an incident angle of 0°, the optical filter transmits at least a part of ultraviolet light having a wavelength within a range of not lower than 190 nm and not more than 230 nm, and transmits at least a part of ultraviolet light having a wavelength within a range of more than 230 nm and not more than 237 nm, and the optical filter blocks transmission of ultraviolet light having a wavelength outside of a wavelength range of not lower than 190 nm and not more than 237 nm.
