The 10-week HRV biofeedback protocol

Ten weeks of HRV biofeedback. A lifetime skill.

Heart rate variability biofeedback lets you gain control over your body's response to stress using signals from your own body. The benefits are felt within weeks — and once learned, cannot be unlearned. Sessions run 45–50 minutes and are entirely non-invasive.

The same protocol taught in this office appears in Dr. Lagos's peer-reviewed research. A sample of what ten weeks of training has produced under study conditions:

In their words

Described as life-changing.

Dr. Leah Lagos is an extraordinary being. I've never known a greater empath. I've also had the good fortune of observing up close her HRV biofeedback training with elite mental performers. The vast majority have described the experience as some version of life-changing, and I've been blown away by the immense performance benefits.

Josh WaitzkinAuthor of The Art of Learning · 8× US National Chess Champion · 2× Tai Chi Push Hands World Champion

I learned to let go and can now shift my stress level, at will, using the tools that Dr. Lagos taught me. The work I've done with Dr. Lagos has changed my life, not only on stage but also off the stage. I find myself expanding and pushing myself into new territories.

Katherine CrockettPrincipal Ballerina, Martha Graham Dance Company

Dr. Lagos was there for me and my team at the University of Miami from day one. She took the time to understand my needs as a coach as well as the challenges that faced our players. She is not only a good listener, but a problem solver who helped to create solutions.

Questions

Before you begin.

Re-training the heart and mind can bring up sensitive conversations that require trust and confidentiality. Every program is sculpted to your specific needs.

What happens at the first meeting?
An initial 55-minute consultation. At its close Dr. Lagos provides recommendations to optimize your health and performance — which may include the 10-week HRV biofeedback protocol, breath and mindfulness training, sleep re-training, or a referral to an outside specialist where appropriate. You decide together how to proceed.
Do I need to be in New York?
