1. A method of significantly mitigating the effects of common colds, influenza, sore throats, and ear infections primarily caused by airborne viruses and bacteria and comprising:
- providing a light applicator including a housing, a power supply, and a light source when energized by the power supply emits light in the ultraviolet range consisting essentially only of UVA light and with a peak intensity of either about 380 nanometers or about 395 nanometers, each intensity with a full-width half maximum of about 20 nanometers, and an output of about 30 microwatts/mm2; and
directing the applicator precisely to aim the light within bodily orifices selected from the nasal passages, the throat passage and the ear passages to directly irradiate the passages within the orifices for periodic times, the periodic time for each passage sufficient for the light to supply the passage at a power within a range from about 10 to about 1000 microjoules/mm2 of the UVA ultraviolet light and sufficient to stimulate the production of an effective amount of hydrogen peroxide by the passages through the process of photooxidation to kill pathogens but insufficient to adversely affect the passages.

Abstract
A method of mitigating the effect of bodily pathogens including providing a light applicator including a housing, a power supply, and at least one light source wherein the light source is configured to emit light in the ultraviolet range when energized by the power supply, and directing the applicator toward a bodily orifice so as to directly irradiate the orifice for a period of time.

8. An ultraviolet light applicator for significantly mitigating the effects of common colds, influenza, sore throats, and ear infections primarily caused by airborne viruses and bacteria, by the applicator producing hydrogen peroxide through the process of photo-oxidation to kill pathogens but insufficient to adversely affect surrounding body cells, the applicator comprising:
-
a housing, a power supply, and a light source including a light emitting diode, the light source when energized by the power supply configured to emit light in the ultraviolet range consisting essentially only of UVA light and with a peak intensity of either about 380 nanometers or about 395 nanometers, each intensity with a full-width half maximum of about 20 nanometers, and an output of about 30 microwatts/mm2; a user interface for selectively energizing the light source for periodic lengths of time to supply the UVA ultraviolet light to each nasal, ear and/or throat passage at a power within a range from about 10 to about 1000 microjoules/mm2 of the UVA ultraviolet light; and an optical light guide proximate the light source including at least one pipe, lumen or cannula to direct the emitted UVA ultraviolet light to the selected passages, each for the periodic times sufficient to stimulate the production of hydrogen peroxide by the body cells through the process of photo-oxidation to kill pathogens but insufficient to adversely affect the body cells. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
