How many times should someone do a Sound therapy session in a week/month? Side Effects?

There are no side effects to Sound Therapy.

How many times should one get it done, depends on the person, and what objectives we are working to achieve.  Sound Therapy can be used to bring a glow to the skin and rejuvenate the blood, circulatory and glandular systems, and this can be done daily.  Some people who suffer from insomnia will have 2 sessions a week to learn how to use vocal toning to relax the body and mind.  So it really depends on the person and what we are working on.
