As well as bringing the rhythm of your breath and heart into sync, BreatheSync deepens your exhalation. This in turn stimulates the parasympathetic branch of your Autonomic Nervous System and that triggers your relaxation response which leads to lower stress and a clearer mind.
Controlled deep breathing has been shown in research to lower blood pressure and improve concentration and performance.
If at any time you feel dizzy, just stop. Consult your doctor or physician.
