Sound vibration is an amazing way to both de-stress and limit the effects of the daily stresses in our lives.  Sound vibration has a massaging effect on the body so you automatically feel looser, but it also reduces cortisol levels and helps to release endorphins so you feel looser, calmer and happier.  Sonic machines are addicting you will want to use them more than once a day because you just feel better when you get off them.
