<p>PROBLEM TO BE SOLVED: To retain or improve physical power or improve the health of a body under various environments and prevent disease, accident or disaster caused by the deterioration of the physical power due to the shortage of oxygen by a method, wherein the concentration of oxygen is increased so as to be about 25 to 40% higher than that of normal air (the concentration of oxygen being about 21%) to bring rest by sucking the oxygen-enriched air. SOLUTION: An oxygen-enriched environmental apparatus is provided with an isolated chamber 2, forming an indoor space 2c isolated from outdoor air, an oxygen-enriched air supplying device 3, installed at the outside of the isolated chamber 2, and an air sending pipe 4 supplying oxygen-enriched air from the oxygen-enriched air supplying device 3 into the isolated chamber 2. According to this method, the oxygen-enriched air is supplied from the oxygen-enriched air supplying device 3 into the isolated chamber 2 via the air sending pipe 4 to constitute an oxygen-enriched atmosphere, whose concentration of oxygen is higher than that of outdoor air in the indoor space 2c of the isolated chamber 2.</p> |
