Developed and tested by Dr. Paul Swingle, the noted psycho-neurophysiologist. The harmonic blend in this CD embodies a proven new technology that has never been sold to the public. Precise frequencies are embedded at a much lower level than the audible filtered “pink noise” that you hear.

This technology has been successfully used in a number of clinical applications, and it has been shown to produce similarly effective results in ordinary, non-medical use among the general public. Includes delta entrainment frequencies.

Here are some of the benefits:

Reduces the time to fall asleep

Effective for restorative sleep

Enhances the quality of sleep

Effective for persons with high stress and pain

It seems like we all know someone who could benefit from Harmonic Sleep ... It really worked! TOOLS does it again ... bringing you breakthrough products to enhance the quality of life.

It can be used for 15 minutes prior to retiring for the night or can be played continuously throughout the night with your CD player set on “continuous play”.
