Abstract

We show that low levels of no coherent and no polarized infrared light induce modifications in human blood cells. An infrared GaAs 6 mW power output light emitting diode irradiate healthy erythrocytes for times from 1 to 30 minutes. We found a threshold time form which light induces changes in normal blood cells, changing its morphology and distribution. Irradiated fresh human blood from 82 healthy patients showed modifications independent of patient's age. This phenomenon may be explained by considering the rotational movement of lipids in both surfaces of lipid bilayer, their magnetic field and interaction with iron hemoglobin.
