1. A bed comprising:
- a bag filled with a transparent fluid, said bag being flexible at least at an upper surface portion thereof, and formed with a transparent portion on a lower surface portion of said bag and on an upper surface portion of said bag;
a bed frame for holding said bag;
a light source, provided on a lower surface of said bag and arranged outside of said bed frame, for emitting light;
light-transmitting means for transmitting said light emitted from said light source to said lower surface of said bag;
an optical fiber, arranged on said lower surface of said bag, for radiating said light emitted from said light-transmitting means into said bag;
a power supply for supplying power to said light source,wherein said light emitted from said light source passes through said transparent fluid and propagates outside said bag through said transparent portion on said upper surface portion of said bag.

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.
