Does anyone know if pulsing over the heart or lungs is safe? i know it's not suggested for users with pacemakers...but has ANYONE tried pulsing over the heart or lungs...does it screw up your normal rthymia?

Also i tried pulsing over my kidneys (backside) for a few sessions...i found that in the middle of the night i would get extremely hungry...does anyone have any clue why? i have slight adrenal fatigue.

thx!
