Photic feedback (PFB) is a method for promoting mental relaxation. In PFB, the frequency and amplitude of alpha waves, which are extracted from the frontal region of the head, are converted into a frequency and brightness of emitted light in real time. We have devised the PFB- Frontal Alpha Wave Pulsed Photic Synchronization (PFB-FAPPS) method, which avoids physical stress to the eyes from PFB-emitting light. We used a 660nm wavelength emission light as a light source, and we exposed the front of the head to the light. Ten healthy subjects each received 15 minutes of PFB-PPFAS 2-4 times a day, and their serum catecholamine levels were measured just prior to the first and the 21st sessions. Activation of the alpha wave rhythm and a significant decrease in serum epinephrine levels and nor epinephrine levels were detected. Repetitive use of PFB-FAPPS could possibly be useful for the reduction of stress.
