Phototherapy as a method of chronobiological therapy features properly timed incidence of light of suitable intensity and spectrum to human to remedy depression or to adjust sleep/wake cycle.
ChBFT is an abbreviation of Chronobiological Phototherapy in Czech language.
ChBFT is suitable therapy for depressions, not only seasonal affective disorder (SAD), but also general non-seasonal depressive disorder and bipolar disorder. ChBFT has rapid onset and short-term duration so pharmacotherapy must be used to stabilize the melioration. ChBFT is evidence-based and well documented by many studies in top medical journals. It is no alternative medicine.
The discovery of circadian rhythm, intrinsically photosensitive retinal ganglion cells, central gene clock in SCN support the therapeutic use of light with anatomical and physiological evidence.
