ABSTRACT:
A bed includes a bag filled with a transparent fluid and formed with a transparent portion at least at an upper surface portion thereof, and a light source for emitting light. The light emitted from the light source passes through the fluid and propagates to an outside of the bag through the transparent portion on an upper surface of the bag. As a result, a bedsore can be prevented, and a decrease in bone mass can be prevented, thus suppressing occurrence of osteoporosis.
