Banish Seasonal Affective Disorder

Research1 shows promising results using entrainment for depression. Particularly with seasonal affective disorder (SAD.) Specific frequencies of entrainment can positive change sluggish brain activity, depression, anxiety, fatigue and carbohydrate cravings. These frequencies increase activity in beta waves and cognitive function while simultaneously suppressing bands of slow alpha activity associated with depression and moodiness.

Our Banish SAD track uses the same frequencies used in the SAD study for both audio entrainment (a matrix of binaural, isochronic and amplitude modulation) and audiostrobe encoding (an enhancement for those with mind-machine devices like the Proteus, Kasina, Procyon or similar which use light goggles.)

The tones acting as “carriers” for the therapeutic frequency are based on the Solfeggio scale. While this scale isn’t validated scientifically, many sound therapists and their clients attest to its tonic properties.

You can try the track for free above, the higher resolution version with the full frequency ranges and audiostrobe is also available for download for iPhones, Androids, iPods, etc.

Dr. Joseph Puleo and Dr. Leonard Horowitz introduced Solfeggio frequencies in the seventies based on Pythagorean reductions of sacred verse. Many report the frequencies are deeply healing and restorative. The “active” ingredient of the track, however, is the entrainment frequency these carry from the study.
