The therapy works by reducing the arousal response that keeps people awake, aligning one’s routine to their circadian rhythm, strengthening the sleep drive, and conditioning the body and mind to have a sleep response produced from the bed. Dr. Holman takes a collaborative approach to tailor the treatment to meet your unique preferences and needs.
