I dislike posts that serve only as blatant advertisements as much as anyone, but I thought our readers would appreciate a link to get $50.00 off an EmWave PC HRV biofeedback system. No apparent expiration date is given so order sooner rather than later because it can be pulled at any time.
EmWave PC is an extremely popular HRV biofeedback system that I use on daily basis in a neurofeedback clinical setting. I have personally found it to be a very effective tool that teaches patients how to self-regulate their autonomic nervous system, to induce coherent breathing, and reduce anxiety.
You can get the discount here.
