Developed by Paul Swingle, Ph.D. from Harvard Medical School and the University of Ottawa, this CD can help reduce the time required for sleep onset. It has been found to be very effective for maintaining restorative sleep, as a complex harmonic blend is embedded at a much lower level than the audible filtered "pink noise" that you hear. Play in the background and use when you are ready to fall asleep.
