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.
