Abstract: A method of biostimulating phototherapy is provided. The method comprises illuminating a subject's body portion with light having a first wavelength in the range of 600-900 nm. The method further comprises the step of at least one of reducing and preventing hyperthermia of the body portion by illuminating the body portion with light having a second wavelength which is at least one of in the range of 400-600 nm and in the range of 900-2500 nm. Further, a phototherapy device is provided which comprises a first light source and a second light source. The first light source is configured to emit light having a first wavelength which is in the range of 600-900 nm. The second light source is configured to emit light having a second wavelength which is at least one of in the range of 400-600 nm and in the range of 900-2500 nm. At least a portion of the device is a patch which is formed for conforming to at least part of the body portion. The device further comprises a sensor for sensing at least one skin property and a controller configured to operate at least the second light source as a function of the determined skin property.
