A human healing ability enhancing apparatus includes an airtight part that is capable of being airtight； a decompression pump that decompresses air pressure in the airtight part and communicates with an exhaust port of the airtight part； and an over-decompression prevention device for preventing over-decompression in which the air pressure in the airtight part is lower than a predetermined threshold air pressure. The apparatus that can favorably provide a stimulus, for enhancing healing capacity of a living body by a decompression control means sequentially and repeatedly controls a decompressing process in which air pressure in the airtight part that is capable of being airtight is changed to a decompression state that is equal to or higher than the threshold air pressure during 1 to 60 minute(s), and a pressurizing process in which the decompression state is changed to a wide-range normal pressure state that is a normal pressure or a pressure higher than the decompression state and lower than the normal pressure during 1 to 60 minute(s) can be obtained.獲得一種人體治癒能力提昇裝置，係具備：可氣密的氣密部、連通於該氣密部的排氣口而將氣密部內的氣壓予以減壓之減壓泵、以及防止前述氣密部的氣壓低於預定的臨限值氣壓而成為過減壓狀態之過減壓防止裝置；藉由控制成連續反覆地進行減壓步驟和增壓步驟之減壓控制手段，可良好地賦予讓活體的自然治癒力提昇之刺激。該減壓步驟，是在1~60分鐘讓氣密部內的氣壓改變成前述臨限值氣壓以上的減壓狀態；該增壓步驟，是在1~60分鐘從該減壓狀態改變成常壓或比前述減壓狀態高但比常壓低之廣泛常壓狀態。
