Photon energy bed can make blood and maintain human body temperature. Better mental outlook and improved immunity.

Photon is a quantum of light, a quantum of electromagnetic radiation, and a standard particle that transmits electromagnetic interaction, and is recorded as γ.

Its rest mass is zero, it has no charge, its energy is the product of Planck constant and electromagnetic radiation frequency, E=hv, it runs at the speed of light C in vacuum, its spin is 1, and it is a boson.
