1. Gas-aerosol bath system which produces a spray (hereinafter referred to as "gas mist") by spraying and dissolving carbon dioxide or oxygen and liquid or a mixed gas (hereinafter briefly called "gas") from carbon dioxide and oxygen and liquid and causes skin and mucosa contact living organism directly with the aerosol at a density of not less than a predetermined value, and which hasgas supply means,gas generating means for generating an aerosol spray of the gas coupled to the gas supply means and having capacity for storing the liquid, a nozzle for supplying gas under pressure and a tube suction fluid for directing fluid to the front end of the nozzle a wrapper for the living body, covering the skin and mucous membrane of the living body, and formed with a space for the insulating gas within the aerosol supplied from the aerosol generating means of gas,sensors for measuring gas flow conditions, the gas and liquid aerosols andcontrol means for controlling the gas flow conditions of liquid and gas mist based on the measured sensor values,wherein the means for generating the gas mist is further provided with means for introducing gas into the gas supply of the gas mist generation means, irrespective of the nozzle to increase the gas supply pressure in the aerosol envelope for the living organism.2. Gas-pressure spray bath system of claim 1, wherein the shell for the living organism connected with pressurization means for the pressure inside the enclosure to a living organism.3. Gas-aerosol bathroom pressure system of claim 2, wherein the pressure generating means is connected with the shell of the living organism and has a hollow gas storage, allowing the gas to produce an aerosol into the shell of a living organism.4. Gas-pressure spray bath system of claim 1, wherein the control means turns on and off the supply of the gas mist into the shell of a living organism, to thereby provide a pressure discontinuity in the sheath for the living organism.5. Gas-pressure spr
