thermally biological effects of infrared lights absorbed have been studied by nonlinear quantum theory and molecular biological theory on the basis of structures of cell and water molecules. There is a large number of water in the living systems, it play an important role in living activity, and has a lot of biological functions. There would be no life without water. We can confirm that the thermally biological effect is a result produced by disorder motions of bio-water-molecules according to the essence of heat, feature of molecular structure of water, theory of molecular physics, principle of resonante absorption and experimental fact that infrared light can heat liquid water. Therefore, mechanism of this effect is that the infrared light absorbed results in the quantum vibrations of water molecules with hydrogen bonds, the vibrational energy again transformes as thermal energy of disorder motions of a great number of water molecules in the living systems. The heating waters can cause a lot of biological effects and phenomena to occur in the living systems. Therefore, the infrared lights absorbed by the living systems have some medical functions.
